BRUNVOLL TWO-SPEED SYSTEM FOR TRAWLER NEWBUILD

BRUNVOLL TWO-SPEED SYSTEM FOR TRAWLER NEWBUILD

Monday, May 10, 2021 

Brunvoll has signed a contract with Cemre Marin Endstri of Turkey, for propulsion and manoeuvring system for a newbuild pelagic trawler, 'Liafjord', designed by Salt Ship Design, for owner Liegruppen Fiskeri of Norway.

The Brunvoll delivery consists of an integrated system package with gear and CP propeller systems with shaft and stern tube, tunnel thrusters and control system. The propulsion system is a two-speed system with PTO / PTH function from a combined shaft generator /electric motor. This means that the ship can supply surplus energy to the main switchboard from the main engine in PTO mode, and in PTH mode the ship runs electrically in emergency mode.

The integrated system package is designed with a focus on user-friendliness, sustainability and the lowest possible energy consumption. The two-speed system is designed for high flexibility with two different propeller speeds for efficient operation adapted to the ship's operating profile. Optimisation of propeller speeds means that the zero-pitch loss is reduced to a minimum, and the ship achieves significant fuel savings, lower emissions, and reduced costs. Liegruppen Fiskeri has been a customer of Brunvoll for many years.

"For the new Liafjord, we have together with Salt Ship Design and Liegruppen come up with a propulsion and manoeuvring system that satisfies the shipowner's requirements for modern, efficient and optimal operation of the vessel," said Geir Arne Kaspersen,VP Sales, Brunvoll.
