Incat Crowther to design catamaran DSVsVessel & ROV News // April 25, 2017
Incat Crowther has secured a contract with Legacy Marine Group of Port Elizabeth, South Africa for the design of two 18m catamaran Dive Support Vessels (DSVs) to be built for Stapem Offshore for operation in the coastal waters off Angola.
The vessels will feature a customized design specific to supporting offshore dive operations. The aft exterior deck utilizes available space by combining deck lockers and racks for diving equipment storage with a covered dive prepping area. The vessel will have four fold-down dive ladders for water access, three swing davits for assisting divers, and one equipment deck crane for additional operational support.
The bow configuration is designed for efficient interaction with personal transfer ladders of Offshore FPSOs and platforms. Robust fendering is to be provided around the perimeter of the vessel to protect it from damage.
The main cabin has seating for fourteen persons and also a SL3 diving operations panel for monitoring dives.
Designed to achieve speeds in excess of 20 knots, the propulsion will comprise two MAN D2876LE402 main engines, each coupled to a Hamilton HJ403 waterjet through ZF 360 gearboxes. Electrical power for the vessel and all dive operations will be provided by two Fischer Panda generators.
Other items fitted below deck include a HPU system with its own designated engine and pump, a Caviblaster system, high pressure and low pressure compressors and storage systems.
