Memo to: Unols Fleet Improvement Committee February 2, 1996
From: Quentin Lewis, Marine Superintendent
Subject: R/V CAPE HATTERAS midlife refit
At the present time, conditions look favorable for a stretch of the HATTERAS in 1998, assuming both NSF approval and funding. Tidewater Navel Architects of Norfolk, Virginia, was hired in late 1995 to perform an initial feasibility study of the HATTERAS concerning a midbody extension. Two items were addressed;
1) What is the largest midbody that can be added keeping the vessel under 500 Gross tons (the cutoff point for Uninspected Vessels)?
2) Could My midbody be added and still allow the vessel to retain its warrant uninspected status?
The answer to #1 is that, based on preliminary tonnage calculations, a 23 foot midbody could be added.
The answer to #2 has not been officially received yet, but all indications from ABS and USCG are that a midbody could be added without a vessel status change.
We are planning to officially propose Phase I (Feasibility study) to NSF this spring. If this is approved and completed in 1996, then Phase II (Contract Design) and Phase III (Detail Design) would be proposed in January, 1997, During 1997, Phase II and III would be completed, and Shipyard Bid Packages sent out by November, 1997. Phase IV (Construction) would be proposed late in 1997. If funded, the actual midlife would be completed during the first half of 1998.
Items to be included in the midlife refit (with stretch) are:
