Incat Crowther to Design 43M Dive Support Vessel
Incat Crowther has been contracted to design a pair of 43m Monohull Dive Support Vessels. The design is an innovative concept comprised of the latest ideas from designer, builder, and operator. The design has been developed to meet RINA class requirements for special service, diving, and dynamic positioning.
The vessels are currently under construction at Arpoadar Engenharia in Guaruja, Brazil, and will be delivered to Oceanica Offshore for service in Brazil with Petrobras.
The aft main deck features a large working deck, which will house the Hyperbaric Chamber, Dive Bell Crane, Portside Deck Crane, and ROV Crane. Inside the main deck house are functional areas including a dive operations office, a workshop, two toilet spaces, laundry room, TV room, lunch room, galley featuring space for a large walk-in cooler and freezer, pantry, and dining/meeting room.
On the mid deck, the outside cabin features a davit crane for a rescue work boat, a waste storage area, and anchor winch. Inside the cabin are crew quarters that accommodate 12 crew members. Each stateroom features bunks, desk, lockers, and ensuite bathrooms.
The upper deck houses a spacious wheelhouse, with forward and aft facing vessel control stations and a desk wrapping around the stairwell for workspace. Aside from perimeter windows providing 360-degree visibility, overhead windows are also fitted both forward and aft for increased visibility around offshore structures.
Below decks are accommodations for the remaining 24 crew members with six 4-berth cabins. All accommodation cabins feature bunks, desks, lockers, and ensuite bathrooms. The amidships portion contains a large machinery space housing compressors, pumps, main switchboard, and other diving support equipment. A sizeable engine room and a waterjet compartment are located aft.
Four (4) Cummins QSK-19 main engines, each producing 492kW, will power the vessels. The vessels will be propelled by four (4) Hamilton HM-521 jets. The waterjet propulsion has been selected to reduce diver risk. Electrical power will be provided by three (3) Cummins QSM 11,300 ekW gensets plus one (1) Cummins 6BT5.9, 92 ekW emergency genset. Two (2) Rodriguez 150kw tunnel thrusters provide maneuvering and station keeping power. The vessels will have a service speed of 12.5 knots.
Incat Crowther's expertise will help deliver a unique design for a dedicated, functional dive support vessel with great standards of seakeeping and crew habitability.
