Hybrid tanker “Tern Island” boasts zero emissions during Gothenburg port operations

14 Feb 2022

Swedish tanker operator Terntank and the Port of Gothenburg will make maritime and environmental history on Thursday (10 February) welcomed Tern Island, a tanker that emits no greenhouse gases or carbon particulates during port operations.

Tern Island is equipped with new electric power supply hybrid systems, including a battery pack, on-shore power supply and a DC-Link system which is reported to be able to reduce its auxiliary energy consumption during port operations by -99%.

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.

Furthermore, Tern Island is 100% biofuel compatible. Its main engine, boiler and auxiliary engine are designed to reduce the environmental impact and perform safe operations running 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 reduces emission by: -70% of CO2 and almost eliminated the emissions of sulphur oxide (-99%), of particle emission, (-99%) and nitrogen oxide (-97%)

Designed by Terntank and Kongsberg Maritime CM AS and delivered on the 15th of December, 2021 at China Merchants Jinling Shipyard, Yangzhou, Dingheng Co. Ltd., the vessel is the first of a series of two 15,000 dwt chemical and product tankers in the Terntank Hybrid Solution® series.

The vessel combines a dual-fuel powered engine that uses LBG (liquefied biogas) or LNG (liquefied natural gas), which means that it is able to operate on completely fossil-free fuel. The vessel, is part of Terntanks most significant expansion order throughout the company’s history, for delivery of a next generation fleet, aimed at sustainable performance.

The Hybrid Solution® of Tern Island does not only enable performance on fossil free port operations, but also enables peak shaving to reduce the emissions even further. The battery packs also provides an energy reserve for power generation, limiting unnecessary parallel running of generators and provides a blackout prevention function that keeps the electrical network alive.

Tern Island has a cargo capacity of 16500 cubic meters in 14 epoxy coated tanks, will be commercially operated by the Finnish North European Oil Trade (NEOT) in the Baltic Sea area and will be included in a pool along with other vessels from Terntank.
