Tugs & Workboats
Bergen Engines delivers robust, fuel-efficient engines designed for tugs and workboats. Our medium-speed diesel and gas engines offer exceptional reliability, low emissions, and flexible fuel options, ensuring your vessels perform efficiently in demanding marine operations.
Tugs and workboats play a vital role in ports, offshore operations, and coastal logistics, often operating in challenging conditions that demand exceptional performance and reliability. At Bergen Engines, we design and deliver medium-speed diesel and gas engines specifically engineered to meet the rigorous needs of these vessels. Our engines provide the consistent power, durability, and efficiency required for towing, maneuvering, and supporting operations at sea.
World’s First LNG-Powered Tugs
Delivered between 2013 and 2014, the sister vessels Borgøy and Bokn marked a milestone in tugboat innovation as the world’s first LNG-powered tug vessels. Built by Sanmar Denizcilik in Turkey and developed in close collaboration with Buksér og Berging, the vessels were engineered for escort, harbour towage, oil-recovery, and emergency towing operations – tasks that demand precision, reliability, and sustained power.
Both vessels are powered by 2 x Bergen C26:33LGPG gas engines each, delivering 1,705 kW at 1,000 rpm. The engines drive azimuth thrusters to provide rapid manoeuvring and a bollard pull of 70 tonnes, while an 80 m³ LNG fuel system with full redundancy ensures safe, stable, and continuous gas operations. The hull and propulsion design deliver 20% higher thrust efficiency compared to conventional tug designs.
Borgøy and Bokn operate under long-term contracts at the Kårstø terminal, supporting Gassco’s critical gas-export infrastructure. Their LNG propulsion offers substantial environmental benefits, including 92% lower NOₓ emissions, 20% lower CO₂, and a 98% reduction in particulates, demonstrating how advanced medium-speed gas engines enable powerful, low-emission performance.
Mission-Ready Performance for Spain’s Emergency Response Fleet
Heroínas de Sálvora sets a new standard in Spain’s emergency response fleet, combining purposeful design with dependable, mission-ready performance. Powered by two Bergen B33:45L8 engines and built by Zamakona Yards, this 82-metre vessel delivers strong, efficient capability across demanding operations. Its hybrid propulsion, DP2 system, FiFi2 firefighting suite, and high-capacity towing arrangement ensure precise handling, rapid response, and sustained power in harsh conditions.
Designed by Seaplace for multi-role versatility, the vessel supports drone operations from a dedicated flight deck and hangar, enabling advanced situational awareness during search-and-rescue missions. Two offshore cranes, a large aft deck, and a full antipollution package, including sweeping arms, skimmers, and 1,800 m³ of oil-recovery capacity, equip the ship for complex salvage and environmental protection tasks.
Heroínas de Sálvora’s design prioritizes efficiency and environmental performance, achieving significant reductions in fuel consumption and emissions through integrated power management and optimized hull form. Accommodations for crew and survivors, medical facilities, and robust seakeeping ensure readiness for long-duration operations.
Reducing Emissions While Increasing Operational Efficiency
OV «Hekkingen» is the latest addition to Kystverket’s environmentally advanced fleet, following the innovative OV «Ryvingen». Built on the same hull design and incorporating the latest hybrid technology, «Hekkingen» continues Kystverket’s focus on reducing emissions while increasing operational efficiency. The vessel is powered by a Bergen Diesel C25:33LA6-1000 engine, paired with a comprehensive Kongsberg-supplied diesel-electric system, including propellers, main switchboard, and bow thruster.
Equipped with two Palfinger cranes and advanced oil-spill response gear, «Hekkingen» is designed for multifunctional coastal operations, including navigational aid maintenance and environmental response. Its diesel-electric hybrid setup reduces fuel consumption and emissions by 30–35% compared to earlier conventional vessels, while still providing the flexibility required for demanding offshore tasks.
The hull was constructed in Poland, with interior outfitting by R&M Ship Interior, and electrical systems installed by Vassnes. The vessel reflects lessons learned from previous ships in Kystverket’s renewal program, combining durability, operational reliability, and cutting-edge environmental technology. «Hekkingen» exemplifies Kystverket’s leadership in sustainable maritime operations and serves as a platform for testing future innovations in hybrid propulsion and low-emission solutions.
