Bukser og Berging expands fleet with hybrid-propulsion tug
Uzmar shipyard has built the first of a new generation of offshore tugboats for a Norwegian owner with electric shaft generators for additional power and lower emissions
Bukser og Berging has welcomed a newbuild offshore and terminal tug to its growing fleet in Norway as it stives to raise safety, efficiency and cut emissions. Uzmar Shipyard built Bube (BB) Power as a hybrid offshore tugboat for the Lysaker, Norway headquartered owner to assist ships, undertake ocean and coastal towage and handle anchors and mooring lines.
This newbuild of yard number NR-171 was constructed to Robert Allan Ltd’s RAmpage 4100BB-H design with a beam of 14.5 m and hybrid propulsion that delivers additional power to enable this 41.2-m vessel to achieve a bollard pull of 120 tonnes.
Berg Propulsion integrated all the propulsion and automation systems for BB Power. This included two main diesel, four-stroke engines from Anglo Belgian Corp, each with 2,800 kW of power and two ABB 900 ekW electric shaft generators and two 3,700-kW azimuth thrusters and one 500 kW bow thruster.
Volvo Penta supplied four 555 ekW auxiliaries, Kongsberg Maritime delivered the advanced winch system for ship towage and anchor handling, Palfinger provided a PK90002H deck crane and Marine Technologies supplied the integrated bridge system and Dynapos dynamic positioning system.
BB Power bridge was designed for full operational command from operator chairs for ergonomics and precise control. It has four control stations enabling crew to operate the winch, manoeuvre the vessel, and navigate using ECDIS, radar and other devices and aids.
“BB Power is a vessel that truly embodies the future of advanced marine operations,” said Bukser og Berging chief technology officer Thomas Sørgjerd. “This hybrid tugboat represents not only engineering excellence and environmental responsibility, but also the strength of collaboration between Uzmar, Robert Allan, and our dedicated team. BB Power will be a cornerstone in our fleet, enabling us to serve with greater capability, safety, and sustainability.”
BB Power has Bureau Veritas class notations Comf-Noise 3 and Comf-Vib 3 with onboard systems designed for crew comfort and low noise and vibration. This 1,100-gt vessel has a beam of 14.5 m, a moulded depth of 7.6 m, an operating draught of 6.6 m, accommodation for 10 crew members, and capacities for storing 450 m3 of fuel and 40 m3 of water.
“BB Power will be a cornerstone in our fleet”
Its deck machinery includes an anchor-handling winch with a maximum pull of 175 tonnes and a brake of 250 tonnes for 670 m of 64-mmm diameter wire, and a towing winch of similar capacity, but with 1,000 m of 64-mm wire.
BB Power also has a 6-m stern roller with a safe weight load (SWL) of 250 tonnes, two tow pins, two sharjaws, two windlasses and two capstans, plus a J-chaser of 110 tonnes SWL and grapnel of 110 tonnes SWL, a storage reel for over 1,650 m of 76-mm wire and another for 1,200 m of 76-mm wire.
“BB Power reflects our commitment to sustainable engineering and our ability to meet the evolving demands of offshore operations with smart, future-forward solutions,” said Uzmar chief executive and president Ahmet Noyan Altug. “Together, we have created a vessel that raises the bar in performance, efficiency, and environmental responsibility.”
A delivery ceremony was held at Uzmar’s shipyard in Turkey the end of September and BB Power will be mobilised to begin operations from the port of Stavanger, Norway in October.
