‘Tern Island’, a pioneering new vessel, designed with Terntanks Hybrid Solution, has arrived at Gothenburg Port, successfully performing zero emissions port operations.
Tern Island is equipped with an electric hybrid power system, including a battery pack, on-shore power supply and a DC-Link system which is reported to be able to reduce auxiliary energy consumption during port operations by almost 100%. The shore power connection has been developed together with the Port of Gothenburg, which is said to be the first port in the world that can connect tankers to electricity.
In addition, Tern Island is 100% biofuel compatible, with main engine, boiler and auxiliary engine all designed to operate safely on biofuels. By combining the optimised hull and rudder design with dual fuel capability, when utilising 30% biogas, in comparison to a same sized conventional vessel, Tern Island can reduces CO2 emissions by 70% and almost eliminate SOx, particulates and NOx.
The ship was designed by Terntank and Kongsberg Maritime and constructed at China Merchants Jinling Shipyard, Yangzhou, Tern Island is the first of pair of 15000 dwt chemical and product tankers in the Terntank Hybrid Solution series. The vessel combines a dual-fuel engine that uses LBG (liquefied biogas) or LNG, which means that it is able to operate on completely fossil-free fuel. The vessel, is part of what Terntank says is its most significant expansion order throughout its history.
The Hybrid Solution additionally enables peak shaving to further reduce emissions, the battery packs providing an energy reserve for power generation, limiting unnecessary parallel running of generators and providing a blackout prevention function that keeps the electrical network alive. Tern Island has a cargo capacity of 16,500m3 in 14 epoxy coated tanks.
The shore power supply is part of Gothenburg’s Energy Port initiative, believed the first of its kind. When complete it will enable a reduction in CO2 emissions from vessels in the port by 1,800t/yr.
