Norwegian vessel owner Bukser & Berging has contracted Turkish shipbuilder Uzmar Shipyard to construct a new offshore tug with hybrid propulsion
Uzmar will build a 41-m vessel for worldwide inshore, offshore and towing operations after the contract was signed at Bukser & Berging’s headquarters in Lysaker, Norway in the final week of December 2022.
Uzmar will build this hybrid offshore tug to Robert Allan Ltd’s RAmpage 4100BB-H design with a beam of 14 m, dynamic positioning and accommodation for 10 crew. The vessel’s hull is designed for maximum manoeuvrability, high bollard pull, good seaworthiness and low fuel consumption.
Its propulsion will include two medium-speed main engines, developing 2,800 kW of power to run two azimuth thrusters with input of 3,700 kW.
Uzmar will equip this vessel with two 900-ekW inline electrical motors and shaft generators for boosting power to the thrusters. These electrical motors will be powered by four powerful generator sets of 555 ekW each.
With both motors and the main engines, this vessel should achieve a maximum bollard pull of around 120 tonnes for offshore towage operations. There will also be a bow thruster of 500 kW to increase manoeuvrability and enable dynamic positioning.
Maximum crew comfort is a priority in the design of the new RAmpage 4100BB-H, as the vessel will have COMF-NOISE 3, COMF-VIB 3 class notations.
