Design considerations of a new generation swath diving support vessel
This paper presents design considerations of a SWATH (Small Waterplane Area Twin Hull) Diving Support Vessel (DSV) presently under construction for delivery in 1995. It is designed to transit on twin pontoons at 12 knots and operate semi-submerged with dynamic positioning or a spread mooring. It will provide multi-purpose support for shallow or deep water operations that include saturation diving support, pipe laying, trenching, well intervention, and offshore fire fighting services for worldwide use. This vessel greatly increases the capability of the offshore industry to perform deep water diving and other support functions in sea conditions that significantly exceed the operating limits of monohulls. This paper summarizes the design basis for the SWATH DSV encompassing the evolution from concept to the final design approved by the American Bureau of Validation of analytical predictions of motion and station keeping with model tests are also presented. The vessel represents an important advance toward cost effective deep water operations.
