Classification society DNV has approved a new series of high-speed eight-cylinder diesel engines ready for workboats and fast transfer vessels
BUKH gained class approval of its V8P series engines following an extensive testing and validation process.
These engines have a power range of 300-530 hp (220-390 kW), 6.6 litre displacement, eight cylinders in the V formation and four valves per cylinder, said BUKH sales manager for Europe and Africa and head of sales support Søren Ortved.
He told Riviera Maritime Media at the SMM 2022 exhibition in Hamburg, Germany these are “powerful, compact, lightweight diesel engines to suit commercial and leisure applications.”
The V8P-300 generates 220 kW of power and maximum torque of 735 NM, while the VSP-530 produces 390 kW and torque of 1,220 NM. Both have a rotary speed of 3,000 rpm at maximum load.
“These engines were approved by DNV for use on fast vessels, high-speed craft, workboats, patrol boats and water taxis,” said Mr Ortved.
Denmark-headquartered BUKH has adapted a Duramax base engine with a nitride-hardened steel crankshaft and aluminium cylinder heads for maritime applications.
The series has a dry weight of 578 kg, a bore of 103 mm, stroke of 99 mm, compression ratio of 16:0.1 and electronic diagnostics functions on a 3.5-in display.
Features include flexible engine mountings, an external fuel filter, front-end gear train and an external oil filter relocated in the upper position for maintenance accessibility. The fuel system includes a cooler, DENSO HP4 high-pressure injection pump with a common rail system and G4S injection system.
BUKH V8P engines also have pilot injections to reduce combustion noise and a seawater-cooled charge air cooler and heat exchanger.
An easily accessible seawater pump is on the engine front and an electrically controlled variable geometry turbo is included. The electrical system includes a 12-V alternator, glow plugs and options for a dual-electric starter and an additional 24-V alternator.
