The Submersible Hull Vessel (SHV™) concept was born out of the marriage of two ideas, one; any normal hull form for a displacement vessel which has reasonable transit speeds but high vessel motion in bad weather and two; the deep semisubmersible which has minimal vessel motion in bad weather but a very slow transit speed. The concept proposes the splitting at or near the water line of any current for future displacement hull form, and allowing that separation to be extended by a combination of the mechanical lifting of the above water portion coupled with a ballasting of the sub merged portion to transform a vessel from one mode of operation to another. The first design is targeting the offshore wind farm maintenance market by using a high speed catamaran hull type for fast transits and transforming that into a semisubmersible enabling on site operations through most weather conditions.
