Reference Projects

Engines for cruise vessels on new Havila Kystruten route along the Norwegian coast

Havila Capella and her three sister vessels are equipped with two Bergen C26:33L6A and two C26:33L9A gas engines each. In total, a delivery of 16 powerful engines, which apply variable turbo geometry to provide an optimal response at all speeds. The liquid natural gas used in these engines reduces CO2 by 25 percent and NOX by an astonishing 90 percent.

Green solutions for three Hurtigruten vessels

A combined project between Kongsberg Maritime and Myklebust Verft will convert three Hurtigruten Norwegian Coastal Express vessels to hybrid operation as part of plans to cut coastal CO2 emissions by at least 25 percent. Two new, energy-efficient Bergen B33:45L6P diesel engines will propel each vessel, equipped with Selective Catalytic Reduction (SCR) to ensure optimal emissions control and compliance with IMO.

Eco-friendly bulk carrier

The gas-powered ship – which can be fuelled using either zero CO2 emission LBG (Liquefied Biogas) or conventional LNG – is being built for the Norwegian short sea shipping company Seaworks. It will be powered by a Bergen C26:33L6P gas main engine.

Powering four new cruise vessels for Mystic Cruises

The 126m, 9,300-tonne luxury craft will join an existing trio of sister ships to bring the fleet to seven identical vessels, the first of which – World Explorer – entered service in 2019. Each vessel will be equipped with two Bergen C25:33L8P main engines and a Bergen C25:33L6P auxiliary dual generator. A hybrid propulsion system allows the Bergen engines to operate at variable speeds, maximising their efficiency for the required power and reducing fuel consumption and CO2 emissions.

New Egil Ulvan Rederi AS multi-purpose cargo vessel

Powered by a Bergen B36:45L6PG gas engine, the new vessel will trade a roundtrip route serving the Norwegian coast from Østfold to Tromsø and will among others have reefer capacity and capability to discharge feed to fish farms.

Medium speed marine gas engines

Our natural gas fuelled marine engines offer exceptionally low emissions of NOx, CO2, SOx and particulates. Innovative technologies like variable valve timing, individual cylinder pressure monitoring and variable turbo geometry ensure optimized and efficient operation.
