DSV SAND ISLAND Technical Specifications VESSEL OVERVIEW

The vessel was originally built in 1982 to serve as an offshore supply and rescue vessel built to ABS and USCG standards. It serves the Cook Inlet and Alaska Gulf coast waters. The Sand Island is an 80' by 25' wide dive support vessel that berths 12 people. The vessel is powered by twin Cummins engines with a combined 700hp. It has the capacity to make efficient crossings in the Cook Inlet Basin against extreme tidal currents. This allows shorter run times between tasks and can reduce travel times. The vessel also supports a deep diving air system and hydraulic tool support. It has enough deck space to support additional equipment as needed. Specifications Owner Global Diving & Salvage, Inc.
