Meeting Minutes
Day
1 November 3, 2004 –
Meeting Called to Order - Dale Chayes, RVTEC Chair, called the
meeting to order at 0830. Florida
Institute of Oceanography (FIO) hosts the 2004 RVTEC meeting on the St.
Petersburg campus of the University of South Florida (USF). The meeting agenda is attached as Appendix
I. Introductions were made
around the room. The attendance list is
included as Appendix II.
Introductory
Remarks - Rob Walker,
FIO, greeted everyone and went over meeting logistics.
Welcoming
Remarks - John Ogden, FIO
Director, welcomed everyone. Dr. Ogden
gave some background information on their institution: FIO is a consortium of 17 members including
the University of Miami. FIO is a UNOLS
Non-Operator member of UNOLS. They fund
100 ship days on a competitive basis to members. Ship time is primarily for educational purposes but there are
some days devoted to research mostly in Florida waters. Dr. Ogden went on to say that, like other
institutions, they are trying to build a new ship to stay in the education-oriented
niche at $3K/day for a 24x7. Their
campaign for a new vessel has been going on for six years.
Agency Reports
National
Science Foundation - Sandy Shor (Appendix
III) - Sandy states
that NSF does not have a budget yet for 2005.
NSF is on a continuing resolution until mid-November. He said to expect a flat budget, plus or
minus a percentage or two. Expect about
3,000 NSF funded ship days this year. Last year was approximately 3,200.
The Instrumentation proposals deadline was three weeks ago. Sandy said he has
about two-thirds in hand and says there is no surprises and that he is
pleased. The Technical services
proposals are due November 15th but only consist of annual reports
this year. Dolly handled two $20M
facility proposals in 2004, one to support acquisition of a new seismic vessel,
and the other a replacement human occupied vehicle at WHOI. The new seismic vessel, Western Legend, will replace Ewing (LDEO) and will be owned
by NSF after the conversion to support research operations. The vessel will be renamed, Marcus
Langseth. The new submersible will
replace ALVIN and have a depth
capability of 6,500m. The design and
build proposal is funded to be completed in two stages, pending proof of hull
welding. There are extensive oversight
committee structures for both efforts.
Sandy also reported that
Jim Yoder (NSF) adjusted the NSF budget process so that ship construction up to
$25M can be supported mid-size Infrastructure within NSF's program
budgets.
Office
of Naval Research (ONR) - John Freitag (Appendix
IV) - John reports
that ONR has a budget for FY2005. Ship time is down approximately 25% this year
driven by program demand. Field program work was high last year and is expected
to high next year. There are about 525 ship days planned so far for 2005, but
will likely go up a bit as the year goes on.
INSURV Associated Science Inspections: R/V Thompson (UW) was the first Navy
ship inspected that included participation by RVTEC members. Seventeen Navy
personnel plus four science personnel (Stewart Lamerdin, Marc Willis, Mike
Webb, and John Freitag) took part in the inspection, which was declared
successful. Two days of the inspection
were held dockside, two were at sea, one day was devoted to the report
write-up, and one day was for the Inspection debrief. A round table review (for
science,) generated a 75-page report. R/V
Melville will be next (in a couple of weeks.) Tony Amos will replace
Stewart on the science team (Stewart will be at sea at the time of the
Inspection.)
Handling Systems: R/V Kilo Moana has
had consistent problems with CTD handling. John said that heavy weather and
small ships are, “an accident waiting to happen.” NSF (Dolly Dieter), and ONR have agreed to fund a study on
different handling systems. The study will not only focus on systems used in
the US but also on foreign vessels as well.
A committee has been formed (Matt Hawkins, UDel (based on his track
record with the lab vans and the R/V Cape
Hatteras replacement), Marc Willis (OSU), Jim Holick (RPS), Andy Bowen
(WHOI), and Tom Althouse (SIO). The
committee has completed a preliminary (non-UNOLS) report that is not yet
public. The first part of the report addresses the Kilo Moana. John said he is
happy to address any questions off the record and also mentioned that the
committee visited several foreign vessels.
A comment was made that RRS James Clark Ross has a very good CTD
handling system, big and expensive, but completely hands-off.
Ocean Class vessels: The
Science Mission Requirements (SMRs) for the Ocean Class vessels are complete.
Hull studies funded by ONR are also complete. The Federal Oceanographic
Facilities Committee (FOFC) long-range fleet plan is being updated on the
5-year schedule. The plan calls for the renewal of the Ocean Class. RADM Jay Cohen announced that he would like
to fund the Ocean Class construction from core 6.1 (R&D) money that is
quite different than the historical approach.
RADM Cohen Is very Interested In the X-Craft hull form, which were
designed a littoral warfare design. He has asked that UNOLS give the hull form
serious consideration. A committee has been formed that Includes Ocean Class
Steering Committee members and the Fleet Improvement Committee who will visit
the shipyard where the X-Craft is under construction. The Admiral says he is
open to other hull form approaches as long as the pros and cons have been weighed. There will be an operator selection process
for the Ocean Class vessels soon.
National Oceanic and Atmospheric
Administration (NOAA) - Mike Webb - Mike reports that NOAA has two new
ships on line. The USNS Indomitable has
replaced the McArthur as the McArthur II. Several other T-AGOS vessels have been transferred to
NOAA over the last few years and integrated into their fleet.
R/V
Fairweather is out of
the shipyard, in Ketchikan, doing charting work in SE Alaska. The Fisheries Research Vessel FRV1, Oscar Dyson has been launched and will be home ported in Kodiak.
FRV2, Henry Bigelow, is under construction at Halter shipyards. Both ships
were fortunate to stay clear of harm from the recent hurricanes.
The USNS Ship Capable has been transferred from the Navy to NOAA with $18M
to convert the vessel for use as an Ocean Exploration vessel. They are developing the
requirements for the conversion.
Mike said that there has been a high turnover of the Electronic Technicians
(ETs). Most of their ETs are very new to this business and there is much
training needed. There is a feeling in some quarters that “You can just hire
people off the street, no problem.” A76 (a contracting out) process is thought
by some to be the right answer.
It was noted that the NOAA Ship Townsend
Cromwell went to American Samoa to be used but it was sold for 1/2 the
value of the fuel that was in it.
U.S. Coast Guard (USCG) - Jon Berkson/
Lt. Cmdr Don Peltonen - Jon reports that heavy Antarctic ice conditions
since 2002 have led to a two-ship norm to break out McMurdo Station. Breakout
had been 50 - 100 NM of ice compared to nearly 200 NM this year.
The propulsion motors on
the USCGC Polar Sea have been
condemned. It is estimated that it will take two years for the repairs to be
made. The ship is currently dockside in
Seattle, WA. The USCGC Polar Star will deploy shortly. Its motors are not that much better than Polar Sea but
they are “okay.” The USCGC Healy is fully operational and had
a port call in Provideniya recently.
Replacement plans: The Ocean Commission’s Recommendation 6-4 says to refurbish
or replace the two USCG polar icebreakers. The CG has commissioned Booz Allen
Hamilton to do a study, which is due in December 2004. The next step will be to
do a mission needs statement and then a preliminary requirements analysis. The Office of Science and Technology Policy
is coordinating a US heavy icebreaker National policy summit that will take
place at the same time as this RVTEC meeting. There will be presentations on past
and present roles, national needs, agencies, funding, and policy. Participants
will include the CG, John Marburger, Dir. OSTP, and NOAA.
John also reports that the Department of Homeland security has their FY05
budget. They have directed funding of a National Academy study on the role of
icebreakers. The report should be out by September 2005.
Research
Vessel Operators' Committee (RVOC) and Safety Committee Report - Bill Martin,
UW (Appendix V) - Bill summarized the reports and workshops
that were provided during the October 2004 RVOC meeting Special reports were
given on the van pool status, the load handling systems,
the long core system, research vessel updates, and vessel security requirements
(CMMS). Speakers included Dennis Nixon who discussed insurance and liability issues for operators.
Bill announced that the medical support contractor for the UNOLS Fleet, Medical
Advisory Systems (MAS) was bought out by Medaire, based in Tempe, AZ.
The UNOLS Safety Committee
plans to re-write the RVOC Safety Training Manual. The chapters will be
reformatted and will be available on the Web including a chapter on hazardous
materials. There will also be a pull
out section to give to chief scientists and PI’s. Revised chapters are due
January 15th. The assignment list is not quite finished yet. There was a
question as to how safe working loads for wires would be addressed in the
manual. The wire committee and load handling committee will provide
information. RVTEC members indicated
that this is an Important Issue that must be addressed by the re-write.
Fleet Improvement Committee (FIC) - Marc
Willis, OSU (Appendix VI) - Marc
reports that there is a projected gap between ship days that will be available
In the future as compared to the estimated ship days needed to meet future
science Initiatives. His slides include
a chart that shows the shortfall. Fleet
renewal efforts are underway:
Regional Class - NSF has
indicated that they will fund the construction of three Regional Class
vessels. They have partnered with
NAVSEA through a Memorandum of Agreement (MOA) to acquire the ships using the
integrated project team (IPT) approach
Ocean Class: ONR is
funding a hull form study that will compare the monohull, SWATH, and
X-Craft. The X-Craft vessel is
currently under constructions at the Nichols Brothers shipyard In Washington
State <www.nicholsboats.com>. UNOLS has been asked for their
recommendation and a decision is needed within a very short time frame. Someone
from the RVTEC community is needed to participate in this effort and in the
shipyard visit on November 17th.
Large ship mid-life refits are coming up soon: Thompson (2006), Revelle
(2011) and Atlantis (2012)
A steering committee has been formed to update the science mission requirements
for the Global ships.
There was then a
discussion of Service Life Extension Projects (SLEP.) The operators of UNOLS
vessels were tasked to provide SLEP estimates that would not enhance the
capabilities of the ships (maintenance only). The estimates range in the price of
$1M to $5M per ship for a 5-year extension. The resulting capabilities would be
considerably less than that called out by the SMRs, that the science would
suffer.
The UNOLS Fleet Improvement Plan update is proceeding as well as the FOFC
Long-Range Fleet Plan update.
Marc updated the group on the status of facility design and construction
efforts for the Alaska Region Replacement Vessel (ARRV), the Cape Henlopen
Replacement Vessel (CHRV), and ALVIN replacement.
The Americans w/ Disabilities Act will have impacts on research vessel design.
The ADA requirements were considered in the ARRV design. There is not as much
guidance in the regulations for research vessels as there are for cruise ships.
FIC is reviewing the ADA requirements to determine how they could be applied to
research vessels.
Arctic Icebreaker Coordinating Committee
(AICC):
Dale reported that:
Break
UNOLS
report - Annette De Silva, UNOLS (Appendix
VII) - Annette
provided an overview of UNOLS activities and goals for 2005. She also provided updates of several UNOLS
Committees: The DESSC has been
participating in the ALVIN replacement
and Hybrid ROV project. DESSC will meet
the day before AGU in December in San Francisco. The SCOAR Committee is working on developing criteria for broader
use and accessibility of aircraft.
Their outreach efforts included an article in EOS and another in
Oceanography Magazine. They continue to
work on the format for an aircraft request form that will be modeled after the
UNOLS Ship time Request form.
Adding a RVTEC liaison to SCOAR has not
moved forward since the last meeting. At the last meeting Steve Hartz expressed
an Interest In serving as the liaison.
The RVTEC Chair will send a letter to SCOAR recommending Steve Hartz's
appointment as an ex-officio member.
Scheduling: The global
ship schedules will be reduced In 2005 to 280 days with down time in each
vessel's home port. There are a large number of deferred ship days slated for
2006.
Quality Improvement Efforts
continue with reviews of the Post Cruise Assessment reports (PCAR) and debriefs
from Kilo Moana. An MTS article on fleet renewal was
published.
Information on
acoustic/marine mammal permitting procedures is available on the UNOLS web site
at: <http://www.unols.org/committees/ssc/permits/permits.html#mamm>.
Peter Wiebe from WHOI was
elected as the new UNOLS chair and Marcia McNutt from MBARI was elected to the
chair-elect position.
Definitions
of Levels of Technical Support – Annette DeSilva, UNOLS (Appendix VIII)
Annette reports that at the last RVTEC meeting it was agreed to standardize how
we communicate UNOLS technical services to the public. A technical services
outline was endorsed at the last RVTEC meeting. No additional comments were
received from RVTEC regarding the outline. The UNOLS Council has
enthusiastically endorsed this approach.
The plan is to develop a fleet-wide database of technical services
Information and centrally maintain the information. Each institution will have to provide their own content. The timeline to have the system up and
running on the UNOLS website is unknown, possibly 6 months. It will depend on the availability of
resources. There are potential conflicts between the offered services and the
post cruise assessment via the database and conflicts between the ship time
request form and the services that are advertised”. UNOLS is working on a
“unified” database that would tie everything together, the ship time request
form, the schedule, the post cruise assessment report, and the technical
services database. The plan is to
maintain a revision history of changes and perhaps an automatic notification of
change service.
The RVTEC was asked to
review and if needed update the list of points of contact. The list will be used to reach the
Individual responsible for maintaining the information.
Ewing replacement - Dale Chayes, LDEO - Dale displayed the PowerPoint
presentation that was provided by John Diebold, LDEO. (Appendix IX). Dale
also mentioned that NSF is returning the Title for the R/V Ewing back to Columbia University so that the ship may be sold.
Alaska
Regional Research Vessel (ARRV) - Steve Hartz, UAF (Appendix X)
Work is continuing on the acquisition of an Alaska Region Research Vessel
(ARRV). Steve reports that they now have an ARRV Website: <http://www.sfos.uaf.edu/arrv/>. They are also working on solutions to
address ADA issues including one ADA stateroom. The ice class is unknown at the
moment. The estimated total cost to build the ARRV will be $83M. The operating
cost estimate is at $23,800/day. Steve said they expect funding to be included
in the NSF/Major Research Equipment & Facility Construction (MRE/FC)
request to Congress in 2006.
R/V Cape Henlopen
Replacement Vessel -
(Tim Deering, UDel.) (Appendix XI) - Tim reported that the
current schedule is for the Cape Henlopen
to be retired from service on October 1, 2005. The shipyard building the
new vessel is Dakota Creek Industries in Anacortes, Washington. New
construction is done using “modular” build.
The final design phase took place during 2004 and construction is well
underway. All major equipment has been ordered and is arriving at the yard. It
will start “looking like a ship” in January 2005, when major outfitting should
begin. The new vessel will be delivered
from the shipyard to Florida by a heavy lift ship on October 15, 2005. The UDEL
crew will deliver the new ship to Delaware. From November 2005 through February
2006 they will cross deck equipment and complete the outfitting of the new
vessel using UDEL funding. The new vessel should be ready to begin operations
around March 2006. 1230 LUNCH
1320 Meeting reconvened
Dale Chayes went over
RVTEC meeting trivia. Candidates for
RVTEC Chair and the venue for next year's RVTEC meeting were discussed. Meeting attendees were instructed to give
their money to Annette for tonight’s dinner.
Acoustic Doppler Current Profilers
(ADCPs)- Stewart Lamerdin, MLML (Appendix XI a and b) - Stewart
presented a PowerPoint presentation summarizing ADCP survey results from the
RVTEC members. Approximately 50% of the
installations include a window. Fouling problems and anti-fouling measures were
discussed.
NSF (Sandy Shor) has funded Eric Firing and Jules Hummon through the SOEST ship
technician support grant to provide some level of support for ADCPs in the
UNOLS fleet. The level of support has not been defined as yet.
Discussion followed on how to quality control the data and questions arose on
how to train and how to deal with troubleshooting and technical support at RDI.
A comment was made that at RDI, their first level of support has not always
been the most helpful. Further comments were that:
-
The
vessel-mounted component of their company is a very small portion of their
business and there have been quality control problems.
-
RDI does
not seem to have much in the way of in-stock spares.
Further discussion items
included:
-
How to
establish configuration parameters.
-
Broad range
of users and levels of understanding on the part of different science parties.
-
The older
narrow band transducers had big problems with transducers de-laminating.
-
Design for
maintenance.
-
There is a
new version of VMDAS coming.
-
Setting up
a list-server for this discussion, particularly when Jules gets back (from her
current event.) Open source might help move this process forward a bit.
OS38
installation on R/V IB Nathaniel B.
Palmer - Michael Carpenter, Raytheon Polar Services (Appendix XIII)
- Mike reported that on
the Gould Installation there was sand blasting grit was trapped in the well and
there was a bubble on the face of the transducer. Ethylene glycol is being used in the wells on the Gould and propylene glycol is being used
on the Palmer. The window is Zelux W
(1 and 1/2” thick) and is optically clear (characteristics are provided in the
slides). There is a waterline free-surface, no hydrostatic head.
Discussion of cables, bend
radius, and interference followed.
Organizational
Excellence Driven by Customer Satisfaction- Mr. Lynn Wright, Architecture for
Excellence (Appendix XIV) - Lynn
presented a PowerPoint presentation giving an overview of their company’s
approach to the process of improving team and organizational performance.
Alliance
for Coastal Technologies (ACT) - Sheryl
Gilbert (Appendix
XV) - Sheryl provided an overview of the ACT program and the Integrated
Ocean Observing System (IOOS)
Coastal
Ocean Monitoring (COMPS) and Physical Oceanographic Real Time Systems (PORTS) -
Cliff Merz, USF (Appendix XVII) - A presentation on in situ real-time
measurements and modeled data was presented.
Center
for Ocean Technology (COT) - Larry Langbrake, Director of the Center for Ocean Technology (COT),
University of South Florida (USF), College of Marine Science The COT Engineering Group are capable of
producing, from the ground up, scientific instruments for use in the research
milieu, especially targeting the oceanographic environment. COT is capable of
production of instrumentation from the conception stage to the actual machining
and assembly of the prototypes and prospective production models. Some of the
on-going projects include a particle imager, called SIPPER, a profiler, known
as BSOP, and an optical platform referred to as the ROBOT. Information about COT can be found at <http://cot.marine.usf.edu/>. Larry reported that they started out
developing applications to go in AUVs.
Then moved on to in situ mass spectrometers and absorption techniques.
Moving on to MEMS so that they can be smaller, less expensive and cheaper. With the increasing demand for micro or
miniaturized devices, COT established its MEMS group. They are able to both
develop and micro-manufacture miniaturized devices. This group is playing an integral part in the development of new
systems for scientific instruments and other devices. They have miniature cylindrical ion traps (500 microns in
diameter.) They have a working one in the laboratory at about 10 ppb
sensitivity. COT is working on 3D
imaging (acoustic and laser line scan) for port security applications.
The day concluded with FIO and USF
Facilities Tours.
Day
2 November 4–
Meeting
business: There are now
three candidates for the RVTEC chair position: Lynn Butler (URI), Woody
Sutherland (SIO), and Bill Martin (UW)
SeaNet
- Dale Chayes, LDEO (for Andy Maffei,
WHOI) - Dale reported for Andy Maffei, who could
not attend the meeting. Dale reports
that at present, operational support for SeaNet continues through Laura
Goepfert at WHOI. Future support for
the program will be through Jim Aikens At WHOI.
Radio Frequency Spectrum – Individuals interested in
participating in this effort should contact the UNOLS office.
HiSeasNet
- Steve Foley (Appendix XIX)
Steve offered some basic
background information on the company and what they can offer. HiSeasNet is an
IP data link at 96k bits per second. It is not RoadNet, which is software. The bandwidth is leased so that they can use
whatever they want with it. The
hardware to run the system is large and is housed at UCSD/San Diego
Supercomputer Center (SDSC.)
The system requires GPS and gyro feed. At the ship end there is a small Cisco router
and a 2.4m SeaTel antenna in a 3m-diameter “dome”. At present, current ships
using HiSeasNet are Revelle, Thompson and Melville. They will be adding the Ewing Replacement, Atlantis
and Knorr. On the downside, in heavy weather the link fails. Traffic can
overload (saturate) the link.
-
Question:
How does the “fair” queue get implemented?
-
Question:
How can they insure the videoconference of “96K”? (Reply - shut down other
services.) Out going (mostly) only
Voice Over IP (VOIP) phone calls.
C-band is $35K/ship/year (bandwidth + support) Limit VOIP to a couple of
handsets on the Revelle.
-
Question:
How much effort is it to take care of the link? Shipboard technicians generally handle maintenance from the ship
end. There are drifts of satellite occasionally. For Windows, they run a local
Windows update server on each ship and control updates from there. By normal
configuration, they block most outbound traffic. They use a web proxy (helps
with traffic management).
SeaWave
- Bill Fanning, URI -
Bill referred to the company’s presentation at last years’ RVTEC meeting. Based on the company’s presentation last
year it was decided to install a system on the Endeavor. Since the company
was local, URI took it on a trial basis. The company was very responsive. But, after it was installed, many felt that
it was not quite ready for prime time. It seemed like they expanded and patched
up an older system that used HF radio to handle new communications channels and
the system doesn’t seem like it was actually designed for this. Two months ago,
the company provided a new system, which is much better. This new system is an
IP-interfaced box. An Iridium and GSM
cell phone are attached. Inmarsat can be used externally but is not working
correctly yet. E-mail is either browser based or IMAP. Phone service is through
a PBX. The cost is about $0.18 per
kilobyte, which is in the range of $.95 to $0.10/kbyte depending upon
efficiency of usage. HBOI/RSMAS have Fleet 55 on one ship and Fleet 77 on the
other. Initially, customer support quality was disappointing but has gotten
somewhat better. UW has a system onboard for phone calls. They have also
changed their billing plan to charge a minimum of $5/per month even if there is
no usage. So, if there is no usage there will be charge and if there is traffic
there will be a $5.00 minimum charge. If you de-assign or delete the account
there can be no traffic.
Question: What is the plan for ships that have SeaWave when HiSeasNet comes on?
Dale Chayes answered that running multiple mail servers onboard leads to far
more hassle than it’s worth.
VSAT
on RRS Ross and Shackleton - Geraint West, Southampton Oceanography Centre
(Appendix XX) - Invsat,
which is a wholly owned subsidiary of Inmarsat is using a commercial earth
station at Aberdeen, Scotland. So far, the stations are run as “ships” (e.g.,
Ross, Shackleton, Rothera, Cambridge). More bases are expected to be connected
this year. They also offer a single mobile email account that can be used
“wherever” you are. They will also perform the same service on the Cook.
The cost to install per ship is approximately 80K pounds ($150,688 US.)
And 3.5 to 5K pounds ($6592 - $9418 US) per ship for higher bandwidth.
Dragging for a lost mooring - George
Tupper, WHOI (Appendix XXI) - The example shown was from Endeavor with a science party of
one. The mooring in the example wasn’t
designed to be released or recovered.
It was working when it was launched but after a few months it was determined
that it was not working. A transit leg was used to install the replacement and
then drag for the failed one. There have been seven of eleven of a suite made
by Webb Research that has failed. There have been two previous attempts to
recover a failed one and to try to figure out what is wrong. George's slides diagram how the mooring was
retrieved. They wrapped the trawl wire
around the mooring and then sawed it off.

INMARTECH
2004 report - Woody Sutherland, SIO (Appendix XXIII) - Woody reported on the INMARTECH 2004
meeting hosted by British Antarctic Survey.
There were approximately eight people from the US and a total of
approximately 40-50 who attended the meeting.
Those from the US were: Woody Sutherland (SIO), Marc Willis (OSU), Toby
Martin (OSU), Sandy Shor (NSF), Barrie Walden (WHOI), Andrew Giard (WHOI), Phil
McGillvary (USCG), and John Freitag (ONR)
Follow
on discussion of INMARTECH 2006 - The meeting location for INMARTECH
2006 will be at WHOI. Eric Zettler
(SEA) and Mary Lynn Dickson (URI) volunteered to work with Barrie Walden to
organize the meeting.
Lessons learned from the 2004 meeting
included:
-
Meeting
focus should be straightforward. It was not made particularly clear in the
past.
-
Transportation
will need to be organized (Boston to/from WHOI) then to/from airport(s.)
-
There also
needs to be organized transportation to/from the meeting and also during.
-
Presentations and talks should contain
substantive information.
-
For
concurrent sessions there needs to be a significant subject content. Is this warranted at present?
-
Expectations
should be that there would probably be a large US contingent in attendance than
at previous INMARTECH meetings due to the fact that there are more technicians
in the US.
-
Effort
should be made to engage a broader international range of groups.
-
Collaboration
should be made with the other INMARTECH folks.
-
There may
be travel funds available from David Blake left over from this year’s meeting.
Foreign
Clearances - Woody Sutherland, SIO (Appendix XXIV) - Woody opened the discussion on how to get
permission to run normal underway data on transits and in foreign EEZs. There are a variety of reporting issues:
timing, formats, media, and content.
Lunch
Meeting
reconvened
There was discussion as to
where and when the next RVTEC meeting will be held. It will be held in the US
on the West Coast and a tentative offer has been made from OSU to host the
meeting in Corvallis sometime in the fall.
No date has been set yet but we need to coordinate and not conflict with
the RVOC meeting and Oceans meetings.

variable speed winch drive
-
Added a
break-out box to allow easy reconfiguration
-
Increased
wing size makes it easier to control.
-
The system
comes only with a pressure sensor and actuator for the wing.
-
With manual
control you can get 6 cycles per kilometer at 6 knots. With auto control, only
one.
-
It is easy
to deploy, more water, easy to add to, small, light.
-
The cost of
Acrobat itself, without SeaBird is approximately $30K.
-
Two 3-4
days 24x7. Usually the science party fly.
-
Controls
are over 4 conductors, data are four more. Nutrient sensors require 1 amp.
Bought a 10-conductor cable.
-
Maximum
depth is 600m but usually doesn’t go deeper than approximately 100m.
-
Controller
software gets depth from the sounder in real-time.
-
If you hit
the bottom, it will roll automatically.
Scanfish
MKII - Dave Nelson, URI (Appendix XXVI)
-
Originally
was made by GMI, now owned rights by EVA, which they bought from Chelsea who
bought GMI. McArtney was supposed to have bought GMI. The engineer who built it
ended up with McArtney.
-
URI, UDel
and Maryland all have similar units.
-
Carries SBE
911 (24 scans/second.)
-
Have
installed fast scan (400HZ) microstructure surveys.
-
Lost the
first one off the Pt Sur two hours into the first cruise. Could not lube
the faired cable.
-
The
original system sampled the water inside the wing.
-
An
emergency beacon was installed on the new tow fish, just in case.
-
It has an
onboard altimeter that automatically causes the auto cycler to turn around.
This does not work right in the presence of a deep scattering layer, which can
be over ridden (with care.)
-
Also have
attitude sensors.
-
Put an
optical plankton counter (OPC) on the fish.
-
Recommendation:
Do not go to sea without a Dremel tool.
-
Minimum
speed is 3-5 knots, maximum is 10 knots without OPC and 8 knots with.
-
Automatic
bottom avoidance feature is very good.
-
Max depth
about 200m w/ 900m of wire out.
-
It is
possible to roll the vehicle if it gets launched up side down.
-
It is
heavier than the Acrobat, but still light.
-
If the
Mocness is the Model T of the fleet, then the GMI Scanfish is the Jaguar.
-
Existing
flight software is MS-DOS based. New, Windows software is in the budget. Also
buy the software to play back the flight data.
-
Ordered
winch was different than what was accepted. The current one is too big and not
computer controllable. Will probably order a new one.
-
A301301
(1/2” wire) three coaxes (fish, CTD and OPC) and two copper (one for power /w
armor.)
-
Recovery
pole w/ hook and V.
-
Gear
deflectors work fairly well, but not against seaweed.
-
The cost
for a Scanfish alone is $95K, and a CTD
is $40K w/transmissometer and winch.
-
The system
is complex and there is a question as to whether or not there should be a
dedicated technician operating the unit.
-
Flaps are
operated electrically via drive screws w/angle sensor and arm.

limit: 10m above the bottom in any water depth
Moving Vessel Profilers
- Arnold Furlong, Brooke Ocean Technology (BOT) (Appendix XXX)
Mr. Furlong presented an overview of their products and equipment, including
handling systems, ocean profiling systems, Moving Vessel Profilers (MVP), laser
optical plankton counter (OPC), free fall penetrometers, handling systems,
small winches, metering sheaves, and moored wave profilers.
He gave examples of
maximum speeds/depths for three of their MVPs:
· MVP30 (to 30m at 12 knots)
·
MVP100
(100m CTD, and sound speed)
·
MVP800
(800meters at 12 knots)
Thirty MVP systems have
been delivered to date. And they have experienced some losses due to cable
termination problems. (e.g., one was snagged while towing and the cable was
stripped off the reel.) One was lost in the UK.
The Dutch Navy performs
about 600 casts per day on two ships.
Cable is Kevlar or Vectran. Only one system has steel (on the ferry) and it’s
showing a bit of bird-caging in armor. Four conductor cables (using two:
RS-422.) Kilo Moana has not used for multibeam yet. It has various sensors: CTDs, flourometer,
LISST, etc.
Kilo Moana
MVP - Steve Poulos, UH (Appendix XXXI) - Steve presented a PowerPoint slideshow
detailing aspects of the installation of their MVP 3000 system that was
installed in July 2004. A few items
were noted:
-
The level
winding of the cable can be done more precisely by moving the drum laterally.
-
Preferred a
SeaBird but took an Applied Microsystems due to shock loading.
-
Loading
cable on the winch is a bit tricky.
-
Takes two
technicians two days to wind/unwind 3,400m of cable.
Lessons learned from MVP on the Discovery - Geraint West, SOC (Appendix
XXXII) - Geraint
reported that they have been using their system since 2001 and have experienced
many problems, possibly more than everyone else combined. They experienced the brake solenoids burning
out when the ship took a significant roll. The Scanfish was lost. The roll was significant enough to shift
equipment in the labs. Inspection revealed that a rope guard was torn and then
the Scanfish was lost. There were
questions as to whether it was an installation or maintenance problem. A formal
report is pending. Geraint said that it was possible that there was enough
roll-induced slack for the rope to catch the guard. A confidence rebuilding
activity is pending after the lesson, (whatever that might be) is learned. But Geraint said that BOT has been very
supportive and there is attitude data available. There is attitude data available.
Ship’s
Wireless Access [Project/Protocol] (SWAP)
- Val Schmidt, LDEO; Toby Martin, OSU; and Geoff Davis, SIO (Appendix
XXXIII) - The SWAP
presentation demonstrated it to be a simple, commercial, inexpensive wireless
networking hardware and software system.
There are seven shore nodes in place at present. There is a 10-step program to begin using
SWAP:
1.
Sign up for
the SWAP list server
2.
Review the
hardware requirements
3.
Determine
antenna locations.
-
There
probably good reasons in a high multi-path (such as ships and water) diversity
antennas. Location matters, Altitude is good. Cable runs and routing.
-
Generate a
hardware list for your installation - you need to if you want to play by your
self.
4.
Get your
network IP assignments
5.
Download,
install and configure the latest SWAP distribution
-Requires a Linux box and a flash card
interface
6.
Assemble
all the pieces
7.
Consider
your networking topology (setup)
8.
Insert your
(properly configured) CF card, boot and test
9.
Install the
hardware on your ship SWAP on!
Broad range of discussion followed regarding scalability and other uses.
System
backup, restoration, dissemination etc - Val Schmidt, LDEO (Appendix XXXIV)
Val’s presentation
included a summary of the responses to the Data Management Survey. A few findings from the questionnaire
revealed that some operating systems are “supported” because some applications
only run on those systems; system admin complexity increases dramatically as
the number of operating systems increases; there have been problems with system
integration and authentication with “all in one” RAID servers administration
front ends; DVD-R and CD-R have longer life than re-writable media; the manufacturing
process (which changes) has a huge impact on longevity of storage. Newer storage media is around 50 years. One
of the failure modes is the type of dye used, another is the lamination
process.
Adjourn day 2
Day
3 - November 5:
MATE
report - by Annette DeSilva, UNOLS (Appendix XXXV) - Annette presented the report submitted by
Jill Zande, which described the MATE Center’s activities and also named the
winning teams at the recent MATE ROV Competition. More information on MATE is available on their Website at: < http://www.marinetech.org/home.php>
There was some follow on
discussion regarding MATE internship experiences. Mostly mixed. A suggestion was made of possibly doing telephone
interviews with interns before they arrive on site.
Equipment Maintenance Database - Ilya
Nikanorov, HBOI (Appendix XXXVI) - Ilya provided an overview of the
structure of the database via PowerPoint presentation. The database was begun in December
2003. A very comprehensive approach was
taken to inventory all equipment.
Included in the database is information on scheduling, resource
management, configuration management, documentation, log books, and knowledge
base built on distributed databases between ships and shore site(s). When done
with this set of goals the intention is to add project management, procedure
development system, financial controls, data comparison, and analysis tools.
Initially the database was began using the Access Software program, and then it
was moved to an MSQL-2000 server. It
was noted that the Web interface also works from PDAs via wireless ‘net.
Although they are trying to be ISO-9000-lite, they do not have a roll out
schedule. At this time the goal is just
to get the inventory system under control. A software developer is working on
this effort.
Question: How would this scale down to
small ship operations? Answer: They
have ~1/2 an FTE working on this effort.
Geraint West commented that his organization is working on a similar effort.
There are tens of thousands of items to catalogue and it can be hard to
get buy-in from technicians, spread
over multiple sites.
Printed
Circuit Board Fabrication and PIC Processor Development - Tom Wilson, SUNY
(Appendix XXXVII) - Tom
began his talk with a humorous disclaimer to his presentation. His PowerPoint talk included step-by-step
instructions for desktop PCB design and fabrication. Also included were descriptions and slides of the various PIC
processors available. Tom also said
that in spite of manufacturer’s claims, there is still a need for the design
and fabrication of custom hardware.
Printed Circuit board fabrication and PIC
processor development: Tom Wilson
-
Print the
design on a magic paper (decal with a glue layer) available from DigiKey,
Mouser, etc. has to be a laser printer.
-
Stick the
“decal” on G4 or Kapton (flexible) with a modified “standard” laminator from
the office supply house.
-
Soak the
decal and then peel the resist off.
-
Etch with a
tank and sponge (with gloves on.)
-
Clean the
resist off w/ acetone
-
Drill
(first)
-
Tin plate
with immersion method, now available from Dow Pro
-
Review of
PIC processor range
-
Microengineering
Labs has a BASIC compiler for PICs.
Cape Hatteras
Internal Communications - John Ahern, Duke U - John said that they are looking to replace their
Atkinsons and family band radios. The
new Atkinsons are greatly improved but don’t mix and match well in some
cases. There are two problems: Internally and out on deck. They use an internal wired intercom system
and external use is via 21MC’s.
There have been problems with feedback if the two units are too close together
because they are so sensitive. Simplex
systems have a problem when trying to countermand a communications problem.
John suggested that if you are looking at buying a new system to attend a
workboat expo where the different systems are available. Whichever one you use or plan to use it is
necessary to have a plan.
Comments and suggestions were made by the group and will be summarized and
circulated to RVTEC:
-
Don’t
forget about hand signals
-
Kilo
Moana: “clear coms”
allows listening to VHF radio communications in the lab.
-
Radios
always have battery problems.
-
Antenna
location.
-
Voice
activated mikes can be a problem in high noise environments (such as on deck.)
-
High noise
(motorcycles, cockpits, etc.) (Autocom, J&R and Baer) radios might be helpful.
-
Wind noise
can be reduced by a separate mike.
-
Noise-canceling
mike makes a huge difference.
Submit ideas to the RVTEC
listserver
Committee
Reports:
Wire Subcommittee - Rich Findley, HBOI - Rich said that a clear definition of “safe working load” is
needed and that the ad hoc committee (Marc Willis, OSU, and Rich Findley, HBOI)
will work on a formal “one sentence” definition which they will then put
forward to the UNOLS Safety Committee.
It was noted that there is already in place a clear definition of
ratings for the over boarding gear chain.
There was some discussion of who and what the safety factor is. Rich, Marc and
Tom will draft a “one sentence” question that RVTEC will put to the UNOLS RVOC
Safety Committee.
A revised UNOLS wire performance spec was posted on the UNOLS website for
review and comment.
Break
Training
and Education Committee - Bill Martin, UW - For next years’ meeting we would possibly like to have Phil
Gibson, Pres., Tension Member Technology (TMT) give a presentation on wire.
Europe and Asia have more
experience with synthetics than in the US. Would be a good thread for INMARTEC
Election
of chair - Jay Tustin, SFSU - Jay
Tustin, Nominating Committee Chair Introduced the three nominees for Chair to
replace Dale Chayes who Is completing his second term. The nominees Included Bill Martin, UW, Woody
Sutherland (SIO), and Lynne Butler (URI).
Voting was conducted and Bill Martin was elected as Chair for
confirmation by the UNOLS Chair.
Discussion
of next meeting location
- Marc Willis, OSU has offered to consider hosting at OSU in Corvallis. The meeting date has not been set but should
be scheduled from about mid-October to early December. Question: Does the meeting have to be at an
operating institution? Answer: Not really,
but it’s nice to see the facilities and ship. It does make it easier for
personnel from the local institution to participate.
Disposal
of Chemicals at Sea – Stewart Lamerdin, MLML - This was a discussion to find out what everyone is doing
on this subject. Questions included:
-
What are
the rules?
-
Where
should guidance come from?
-
What goes
down the drain?
-
What can go
over the side?
Comments made included:
-
The Seawolf
is a zero discharge vessel but it only handles very short legs.
-
Storage on
board can be problematic and/or raise safety issues.
-
Point: At
SIO, UCSD guidelines apply, then SIO reviews the plan(?) Answer: They usually
go along if the home institution assumes the liability.
-
USCGC Healy has a list for handling chemicals.
-
Your
institutional safety committee will have guidelines. Most, (if not all)
institutions require an end-to-end plan for chemical handling.
-
Bill said
that as part of his participation in the safety committee he would re-write
this chapter for the safety committee. An early draft will be circulated to the
RVTEC list for comment. This chapter has to be complete by January 15th. Draft
will be sent to the list by mid-December for review.
-
Physical
safety issues associated with outside storage of HAZMAT. No more than a one day
supply in board.
Notice - Human powered submarine races are
being revived. Contact
