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). 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. The paper summarizes the design basis for the SWATH DSV encompassing the evolution from concept to the final design. Validation of analytical predictions of motion and station keeping with models tests are also presented.
