Port’s inspection vessel now electrified

21 Mar 2024 / Gothenburg, Sweden

Having served round the clock as an inspection vessel in the Port of Gothenburg since 1979, M/S Hamnen has now been converted to electric propulsion. Following today's re-inauguration, the vessel is expected to remain in service for many years to come…

…The vessel undertakes a variety of tasks, but its foundation lies in representing the Port Authority and ensuring compliance with regulations according to port ordinances. Around the clock, all year round…

M/S Hamnen is in active operation for approximately 1200 hours per year. With the previous engine, the vessel consumed 25,000 liters of diesel, resulting in 67 tons of carbon dioxide emissions - equivalent to 15% of the Gothenburg Port Authority company’s total emissions - which are now eliminated.

A total transformation has taken place in the engine room as the previous diesel engine has been replaced by a brand-new electric motor with 250 kW of power. In addition, a battery bank of 520 kWh has been installed, which can be supplemented with additional battery capacity in the future if required. A diesel auxiliary engine has also been installed, which can be activated in exceptional circumstances…

…The vessel left the Ö-varvet shipyard on Öckerö in the Gothenburg archipelago in January. In addition to electrification, the vessel also received a new bridge, as well as a range of measures to enhance working environment and extend lifespan. Since then, the vessel has undergone real-world testing before today's official re-inauguration…
