Wartsila engines for ROV mothership
Wartsila Corporation has been awarded a contract worth about EUR 2.7 million by Aker Yards ASA to supply main engines for a new offshore support vessel contracted by Geo ASA. (See earlier story)
The main engines will be four six-cylinder Wartsila 32 diesel engines with a combined output of 11,520 kW at 720 rpm.
The vessel will principally serve as a mothership for unmanned remotely-operated subsea vehicles (ROV) which can be launched by crane over both sides of the vessel as well as through a moon pool.
Important requirements concerning the choice of engines included low fuel consumption and fulfilment of the Clean Design notation of DNV classification.
The Clean Design notation sets high environmental standards for the control and limiting of all types of emissions and discharges. These standards involve not only the choice of equipment in a vessel, and its installation design but also a vessel's operational procedures.
