DANFOSS DRIVES AND BIOFUEL HELP DECARBONISE MAERSK SUPPLY SHIP

DANFOSS DRIVES AND BIOFUEL HELP DECARBONISE MAERSK SUPPLY SHIP

Friday, December 10, 2021 

The Maersk Supply Service vessel 'Maersk Tender', which uses Danfoss AC drives to power its thrusters, has completed a test with The Ocean Cleanup to mix biofuel into marine oil to reduce CO2 emissions.

According to Danfoss, test results were very promising, but as biofuel is an expensive alternative to standard marine oil, the trial was carried out to provide valuable insight into technology which further reduces emissions in the long term. The retrofit with AC drives from Danfoss Drives on each of its four thrusters is part of this carbon-cutting exercise, helping to achieve energy savings, since the thrusters no longer rotate continuously and thus only consume electricity when actually required. Thrusters usually run at full speed. Now, each is controlled individually, which is useful when running in DP mode, during which fuel savings of around 30% were recorded. Danfoss Drives supplied two 800 kW VLT AutomationDrive FC 302 and two 500 kW VLT AutomationDrive FC 302 units for control of the thrusters.

In addition, Maersk Supply Service installed Danfoss AC drives to improve efficiency of all engine room fans. According to the company, the results of this study can now pave the way for similar upgrades to be carried out on several of Maersk Supply Services’ T-class vessels.

Caspar Daugaard Andersen, Key Account Manager, Danfoss Drives Sales Denmark, said: "It has been an exciting process to help make a difference in reducing the carbon footprint at Maersk Supply Service. We have many other exciting collaborations in the pipeline, where we will hopefully achieve the same good results."
