The Bergen B32:40 is derived from the B32:36 series, first introduced in 1985. The long stroke version was launched in 2001. Compact and powerful with low fuel consumption, the B32:40 engine family is able to operate on Marine Diesel Oil (MDO) and Heavy Fuel Oil (HFO).
In 2006, the first B32:40 engines with Tier 2 certification entered service. These stringent emission levels are met with no additional off-engine clean up features, 6, 8, 9, V12 and V16 engines are available with powers of 2,880 to 8,000kW.
This 6th generation rig will be able to operate in extreme conditions such as ultra deep waters, tough weather regions including the Arctic, and locations far from established infrastructure.
It is designed to operate in wave heights up to 36m.Eight Bergen B32:40 V12A generator sets provide all the power which totals 42,400kW.
Two of the eight units will be classed by DNV as emergency units capable of operating at 25 degrees of inclination in any direction.
This unique circular production platform has been developed by Sevan Marine in Norway and is capable of operation in ultra deep waters and in harsh conditions.
It is powered by 8 Bergen B32:40V12A engines, which drive eight Rolls-Royce UUC 355 azimuth thrusters each rated at 3,800kW as well as providing electrical power.
A 92.7m anchor-handler of 4,800dwt. Four Bergen B32:40L8P CD engines provide a total power of 16,000kW to give a bollard pull of 240 tonnes. A special Rolls-Royce hybrid propulsion system reduces the amount of fuel burnt by matching power to the operating mode.
Various combinations of diesel mechanical and diesel electric drive can be selected. In addition a catalyst system for exhaust treatment was specified to further reduce emissions.
Equipped with a 500t anchor handling winch the vessel is powered by two Bergen B32:40V12P engines that drive CP propellers in nozzles. With the two azimuth thrusters fore and aft deployed bollard pull is in the region of 230t. Island Vanguard can place anchors with precision at depths up to 2,000m.
