Incat Crowther has announced the delivery of Sistac Victoria, a purpose-built RINA-classed, DP-2 monohull dive support vessel intended for service in Brazilian offshore waters.
The vessel was designed by Incat Crowther in collaboration with the vessel’s builder, SeaSafe Barcos Manufacturados S.A. in Angra dos Reis, Brazil for Sistac Sistemas De Acesso S.A.
The Sistac Victoria’s aft working deck includes multiple A-frame assemblies with integrated winches for ROV and dive bell launching and retrieving as well as a knuckle boom crane for handling deck gear and a small rescue/service vessel. The aft deck also features a lower platform at the stern to facilitate direct access to the sea by diving personnel. Completing the aft deck arrangement is a dive shop and dive control center, which is centrally located on the aft deck.
Below decks are accommodations for the 33 crew and dive personnel, which are designed as two, three, and four-berth cabins.
A wheelhouse features forward and aft facing controls, numerous lockers, a refreshment center, and two ROV control stations. A large deck ahead of the wheelhouse provides a landing area complying with Petrobras requirements for accommodating a crane-loaded man-riding basket, and for carriage and delivery of supplies and small cargo.
Four Scania DI13 main engines driving Hamilton HM 521 waterjets through ZF 665 gearboxes supplies propulsion power to the vessel. Diver safety and maneuverability were key drivers in the selection of waterjet propulsion. Station-keeping and maneuverability are further enhanced by three Thrustmaster 30TT200 tunnel bow thrusters. Main electrical power is supplied by four Scania DI13, 375 ekW gensets.
