Delivery of 43m Dive Support Vessel

By Joseph R. Fonseca

Incat Crowther completed delivery of the Oceanicasub
V, the second of a pair of 43m Monohull Subsea Dive Support
Vessels (SDSV) constructed by Arpoador Shipyard in Guaruja',
Brazil.

The vessels are owned and operated by Oceanica of Rio de Janeiro
for charter by the Brazilian oil giant, Petrobras. The innovative
design is the culmination of a close collaboration by the
designer, builder, and operator.

The RINA-classed vessel is efficiently equipped for a crew
complement of 36 and features a wide 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. As a result, the
vessels are exceeding expectations of both operator and
charterer.

Four (4) 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 (3) Cummins QSM 11, 300 ekW gensets plus one (1) Cummins
6BT5.9, 92 ekW emergency genset. Three (3) 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.
