Our Technical Department is continuously developing advanced vessel designs and optimizing technical solutions across existing fleet and newbuilding projects.
Recent innovations and technology developments include:
- LNG‑powered Escort Tugs (Borgøy and Bokn)
Development and delivery of the world’s first LNG‑fuelled escort tugs for the Kårstø terminal. The LNG system, engineered by AGA Cryo, incorporates an 80 m³ LNG tank, dual cold boxes, and a fully integrated bunkering system. Both vessels hold DNV Gas‑Fuelled notation and were designed to demonstrate reduced emissions and stable low‑vibration operation under high‑load escort conditions. - High‑Performance Escort Tug Design with Voith Propulsion
Design and implementation of an “egg‑shaped” hydrodynamically optimized escort‑tug hull form. When paired with Voith Schneider Propulsion, the vessels achieve a DNV‑classified steering force of 160 tonnes at 10 knots. The propulsion arrangement increases water inflow efficiency during escort operations, improving course‑keeping forces and overall escort performance. - Low‑Emission IMO Tier III Escort Tugs
Over the past decade, Buksér og Berging has introduced a series of next‑generation escort tugs designed to comply with IMO Tier III NOx emission limits. These vessels incorporate optimized combustion, advanced exhaust after‑treatment, and improved operational efficiency to reduce emissions during high‑load escort towage. - Zero‑Emission Harbour Tug (BB Electra)
BB Electra is the first fully electric tug in operation in Northern Europe, delivered in 2024. She is powered by a 1,718 kWh Corvus battery system that enables zero‑emission operation in harbour towage missions. A Caterpillar C32 IMO Tier III‑compliant diesel generator provides redundant backup power for extended operational envelopes and emergency capability. - Hybrid Offshore & Terminal Tug (BB Power)
BB Power is a high‑capacity hybrid offshore and terminal tug designed to Robert Allan Ltd.’s RAmpage 4100BB‑H specification, delivered in 2025. The vessel is equipped with two 2,800 kW diesel main engines with two 900 ekW electric shaft generators, delivering a bollard pull of 120 tonnes for offshore towage, anchor handling, and coastal assistance. An innovative integrated bridge system from Marine Technologies provides four operator stations. - Fuel Reduction Technologies in Pilot Boat Operations
Cutting 25% of fuel consumption on pilot boat operations by implementation of Volvo’s IPS propulsion and weight control by dynamic loading conditions.
