Sweden: Sludge oil collection tanker “Northern Skagerrak” to undergo hybrid conversion

05 Jan 2022

The sludge oil collection tanker Northern Skagerrak will be converted to hybrid operation during the second quarter of 2022, informs the Gothenburg Port Authority.

The vessel will run mostly using electric power and be fitted with an auxiliary engine that runs on the renewable hydrogenated vegetable oil (HVO).

All ports in Sweden are obliged to receive sludge from ships arriving at the port. Northern Skagerrak will collect oily engine room waste, known as sludge, from ships arriving at the Port of Gothenburg.

The Gothenburg Port Authority procured the service from Northern Energy & Supply and the service ship will begin operating during the second quarter of 2022.

The conversion will save 680 tonnes of carbon dioxide.

“We are a company that is very much at the forefront in developing innovative solutions,” said David Kristensson, Group CEO at Northern Energy & Supply.

“We are grateful once again to be entrusted with the task of working with the Port of Gothenburg on a project that will result in an improved environment in the Gothenburg area.”

When the invitation to tender for sludge collection was issued, the Port of Gothenburg climate objectives were used as a starting point in the evaluation model.

Carbon emission mitigation was one of the quality criteria applied when assessing potential service providers.

Following collation and evaluation, the Northern Energy & Supply fossil-free solution proved to be the best option.

“Our aim at the Gothenburg Port Authority is to reduce carbon emissions at the port by 70% by 2030,” notes Erik Waller, Deputy Harbour Master at the Gothenburg Port Authority.

Northern Skagerrak will serve around 6,000 incoming ships each year and the conversion to hybrid operation will be a significant step in the right direction.”
