Maersk Supply Service to install first hybrid battery on AHTS

Maersk Supply Service has chosen a hybrid battery pack from Wärtsilä to retrofit the Maersk Minder, a diesel-electric anchor handling tug supply (AHTS) ship built at Kleven Werft in Norway and delivered in 2018.

One of six M-class vessels, the Maersk Minder is due to operate in the North Sea from the third quarter of 2021. The battery installation will be carried out late in 2021 or early 2022, depending on delivery time. The conversion is designed to meet its customer’s demand for lower carbon vessels, Maersk Supply Service said.

“To the best of our knowledge, this will be the world’s first AHTS hybrid battery conversion,” said Mark Handin, chief operating officer of Maersk Supply Service. “We believe that we are on the leading edge in terms of bringing this technology into the AHTS segment.”

Allan H. Rasmussen, head of Technical Organisation in charge of decarbonisation initiatives at Maersk Supply Service, added: “The expectation is that the new battery pack will decrease the fuel consumption and thereby reduce CO2 emissions by 15%. With the specialised tasks and variety of operational capabilities, it is important that we thoroughly test the vessel setup utilising the batteries and validate the CO2 savings during the first few months of operations.”

Since 2018, Maersk Supply Service claims to have reduced carbon intensity across its fleet by 13% and has allocated resources for future upgrades to reduce emissions further.

The company currently operates 28 AHTS vessels.
