Maersk Supply Service orders a Wärtsilä battery for

Danish offshore support vessel owner Maersk Supply Service has ordered a battery pack for one of its M-class vessels, Anchor Handling Tug Supply Maersk Minder, as part of its plan to reduce the intensity the company’s carbon footprint by 50% on its entire fleet in 2030..

Mark Handin, COO of Maersk Supply Service, said: “Maersk Supply Service is playing an active role in decarbonizing the offshore support vessel industry. This requires both behavioral changes in the way we operate our vessels, as well as technological upgrades to our fleet.With this new upgrade to the hybrid battery solution, we are taking an important step forward on our path to further reduce emissions from our diesel-electric vessels.

“The use of hybrid batteries / energy storage systems has proven to be an effective solution in the platform supply vessel (PSV) industry; however, we believe we are on the cutting edge in terms of integration of this technology into the Anchor Handling Tug Supply Segment (AHTS). To our knowledge, this will be the world’s first AHTS hybrid battery conversion, “says

Maersk Supply Service chose Wärtsilä as their hybrid battery supplier, citing Wärtsilä’s extended battery life and innovative design that helps reduce ship emissions, reduce maintenance and increase operational performance.

For its first ship battery installation, Maersk Supply Service selected the Maersk Minder AHTS, SALT design, designed for deep water anchor handling and oilfield operations.

“Powered by five mid-speed engines with a total output of over 23,000 horsepower, a flexible and fuel-efficient hybrid propulsion system and a fixed pitch on all side thrusters, the vessel offers good fuel economy, low emissions and excellent station keeping capabilities (ERN 4 x 99), “MSS vessel description reads.

“The vessel will operate in the North Sea from the third quarter of 2021, with plans to install the battery in late 2021 or early 2022, depending on delivery time. The concept is designed to meet our customers’ demand for vessels to low carbon, ”the company said. .

Allan H. Rasmussen, head of technical organization and responsible for decarbonization initiatives at Maersk Supply Service, said the new battery pack is expected to reduce fuel consumption and thereby reduce CO2 emissions by 15%.

“The responsibilities of anchor handling vessels vary widely, from heavy towing of floating units at sea to underwater work in dynamic positioning mode. Given the specialized tasks and the variety of operational capabilities, it is important that we thoroughly test the vessel configuration using the batteries and validate the CO2 savings during the first few months of operation, ”adds Rasmussen.

Kenneth Bang, Account Manager at Wärtsilä: “The Wärtsilä Low Loss Hybrid Battery System (LLH) integrates seamlessly with a conventional engine, such as Maersk Minder. load fluctuations thanks to the batteries. We see this renewable LLH solution as an ideal solution for Anchor Handling Tug Supply Vessels. “

According to Maersk Supply Service, the company has since 2018 reduced its carbon intensity by more than 13% across its entire fleet.

As a reminder, Maersk Supply Service said earlier this month it would change the flag of one of its anchor handling vessels to the Norwegian flag, hire a Norwegian crew and open an office in Bergen. The plan is to have its first vessel ready for operation in Norwegian waters during the summer of 2021, the company said.

The marine engineer asked Maersk Supply Service at the time which ship exactly would be sent to Norway.

“We expect it to be Maersk Minder,” a Maersk Supply Service spokesperson said.
