New Horizon Mid-Life Refit:
Project Goal: Improve New Horizon' s ability to support scientific operations by taking maximum benefit of the opportunity presented by an extended mid-life refit period through orderly planning and execution of repairs and upgrades which will ensure continued reliable operations and which conform to the UNOLS "Scientific Mission Requirements for an Intermediate General-purpose Oceanographic Research Ship" as closely as possible. Elements of the refit which support this goal are:
Resolution of long-standing stability problems,
Repairs, upgrades, and modifications that improve operation, reliability and maintenance of the ship by correcting design deficiencies, replacing worn out or obsolete equipment and machinery and capitalizing on technical advances since delivery,
Improvements, modifications and installations which will result in improved ability to support scientific operations in both coastal and open ocean areas,
Habitability improvements resulting in a higher quality of life for the science party and crew
Funding: The funding for the planned refit will come from three sources. Normal overhaul projects will be funded from the Major Overhaul Stabilization Account. The University of California' San Diego proposes to share the remaining cost of the refit with the National Science Foundation. The University's percentage of the cost will be the same as the percentage of use for state projects. Historically , in the past 10 year period since 1985, this amounts to 21% of ship's scheduled operations. An estimated cost breakout will be presented later in this proposal.
Timing: New Horizon completed her last regular overhaul period in January 1993. Normal interval between dockings is 2-2 1/2 years. A conscious decision was made to extend this interval to ensure that the ship was available for science during 1995 because of a large number of requests for her services. Additionally, predictions from funding agencies for 1996 have consistently indicated a lighter operating schedule for-all ships. As an ABS classed vessel, she must be drydocked and inspected no later than January 1996 to remain in class . Normal maintenance and repair efforts have continued during this extended period, but the ship now needs overhaul. This timing also supports accomplishment of work items scheduled at intervals longer than the normal 2 year cycle such as gearbox overhaul and tail shaft clearance measurements which are now due.
1995's operating schedule for New Horizon currently ends on 21 November. We propose to immediately place the ship "out of service, and commence preparing for the shipyard phase of the refit which will commence in December. Upon completion of the shipyard availability, New Horizon will return to Nimitz Marine Facility for a second phase which will consist of additional contractor and MARFAC shop work. We plan to complete the refit in approximately five months.
Scope: As evidenced by her ability to successfully complete extensive, complex science schedules each year, New Horizon is in excellent material condition with a minimum of deferred maintenance. Engines, pipinq systems and the ship's structure are fully sound. The long standing stability problem which result in a limit on mission duration have been continually documented. Correction of these problems is the highest priority and in the refit package. Because the work necessary to resolve stability problems is so extensive, it will define the critical path of the refit Another major item is the replacement of the underpowered, retractable bow thruster with a modern tunnel thruster
Improvements in deck systems will be included to take advantage of the full capabilities of the DYNACON traction winch which was installed in 1994 as an .initial phase of the refit.
A common occurrence in shipyard overhauls which can cause significant delays and cost over runs is the discovery of asbestos in a ship after commencement of work. To guard against this possibility, a full hazardous material survey of the ship has been accomplished with UC funds. This survey verified that New Horizon is asbestos free
The following four tables detail the work planned during New Horizon's mid-life refit. Items funded in previous Shipboard Scientific Support Equipment or Oceanographic Instrumentation Proposals are indicated. The tables cover;
With funding provided as part of the University of California cost share, the Glosten Associates conducted a Feasibility Study of major mid-life refit work items. After review of this study and selection of the applicable items, UC funding was provided for development of detailed work-Item Specifications, General Specifications, Work Item Drawings and a Purchase Specification for Tunnel Thruster, which have been used to develop cost estimates for major elements of the refit. Justification of all work items in the tables is provided in Appendix A. Annex I to Appendix A contains the detailed Work Item Specifications, Work Item Drawings, General Specifications and the Purchase Specification for Tunnel Thruster developed b-y the Glosten Associates for the major structural refit items. Annex II is the Glosten Associates letter describing estimated costs-for various options to resolve the ship's current admeasurement problems. Vendors, quotes and other amplifying information related to overall refit costs are included in Annex III.
