Oceanicasub V, the second of a pair of 43m Monohull Subsea Dive Support Vessels (SDSV), has been delivered for owner and operater Oceanica of Rio de Janeiro for charter by Petrobras.

Oceanicasub V was constructed by Arpoador Shipyard in Guaruja’, Brazil. The design is the culmination of a close collaboration by the designer Incat Crowther, builder and operator.

The RINA-classed vessel is equipped for a crew complement of 36 and features an array of dive support equipment including deck crane, ROV A-frame, dive bell A-frame, hyperbaric chamber, HIPAP, rescue/workboat with associated davit and all necessary dive operations related spaces and equipment. Crew accommodation and operational spaces are finished to a high standard and the layout of machinery and open deck spaces are well thought out to provide safe operations, according to the designer.

Four Cummins QSK-19, 660 bhp main engines, coupled to Hamilton HM 521 waterjets through ZF 2000 gearboxes, provide propulsion power to the vessel. The waterjet propulsion has been selected to reduce diver risk. Electrical power is provided by three Cummins QSM 11, 300 ekW gensets plus one Cummins 6BT5.9, 92 ekW emergency genset. Three Thrustmaster 150kw tunnel thrusters provide maneuvering and station keeping power. Class 2 dynamic positioning is provided via a Kongsberg system and a quartet of Intermarine fin stabilizers are provided to reduce vessel motions and enhance crew comfort.
