DSV Sistac Victoria deliveredVessel & ROV News // March 12, 2015
Designer Incat Crowther has confirmed the delivery of Sistac Victoria, a purpose-built RINA-classed, DP2 monohull dive support vessel (DSV) intended for service in Brazilian waters.
The vessel was designed by Incat Crowther in collaboration with the vesselís builder, SeaSafe Barcos Manufacturados SA in Angra dos Reis, Brazil for Sistac Sistemas De Acesso SA.
Sistac Victoriaís generously sized aft working deck includes multiple A-frame assemblies with integrated winches for ROV and dive bell launching and retrieving as well as a knuckleboom 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.
The interior of the main deck house includes an emergency generator space, a decompression chamber, office, TV/entertainment Room, meeting room, lunch room, galley with generously sized freezer, cooler, and pantry, and three single-berth cabins with en-suite bathrooms for senior personnel.
Below decks are accommodations for the 33 crew and dive personnel, which are designed as two, three, and four-berth cabins, each with their own en-suite bathrooms.
A spacious wheelhouse features forward and aft facing controls, numerous lockers, a refreshment center, and two 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 manoeuvrability are further enhanced by three Thrustmaster 30TT200 tunnel bow thrusters. Main electrical power is supplied by four Scania DI13, 375 ekW gensets.
