In 2010, GPA signed a contract with Brazilian shipyard EISA. Estaleiro Ilha for one GPA 462 OSRV, designed specifically to Petrobras requirements (OSRV 750). Later on, an order for one identical OSRV followed. Both vessels are currently under construction at EISA for the Brazilian offshore operator Astromaritima Navegacao S/A.
The GP 462 OSRV, measuring 62-meters in waterline length, are outfitted with a diesel-electric propulsion configuration. The system consists of two azimuthing drives, each rated for 1,700kW, and two bow thrusters, each rated for 448kW. The propulsors and bow thrusters will run on three generator sets each rated for 1,700kW.
The use of a diesel-electric propulsion system creates valuable flexibilities, allowing for the maximization of cargo carrying capacities below deck, as the engine room is located above the main deck. Besides fresh water tanks (315 m³), permanent fuel oil tanks (489 m³) and day oil tanks (33.3 m³), these OSRVs will be capable of transporting a maximum of 800 m³ of recovered oil.
