Maersk to test electric charging buoy at Ørsted offshore wind farm in 2021

01 Oct 2020

A.P. Moller-Maersk on Monday (28 September) said Maersk Supply Service A/S, a part of A.P. Moller-Maersk, has joined forces with Ørsted, the world leader in offshore wind, to test a proto-type buoy that will act as both a safe mooring point and a charging station for vessels, potentially displacing a significant amount of marine fuel with green electricity.

 

The solution, developed by Maersk Supply Service, will be tested on one of Ørsted’s offshore wind farms in 2021, it said.

 

The aim of the partnership is to test an innovative charging buoy that can bring green electricity to offshore wind farm service vessels and potentially to a wide range of maritime vessels.

 

The buoy can be used to charge the smaller battery- or hybrid-electrical vessels and to supply power to larger vessels, enabling them to turn off their engines when laying idle, explained Maersk.

 

By substituting fossil-based fuels with green electricity, virtually all emissions are eliminated while the buoy is in use.

 

The proto-type buoy has been developed by Maersk Supply Service while Ørsted is responsible for the buoy’s integration with the electrical grid at the offshore wind farm.

 

The charging buoy will be tested in the second half of 2021, where it will supply overnight power to one of Ørsted’s service vessels.

 

Upon technical validation and commercial ramp up, the electrical charging buoy has significant potential, short to medium term, to contribute positively to reduce emissions for the maritime industry.

 

Within five years of global operation, Maersk Supply Service said it has the ambition to remove 5.5 million tons of CO2, additionally avoiding particulate matter, NOx, and Sox.

 

Ørsted intends to make any intellectual property generated in designing the integration of the buoy into the offshore wind asset publicly available to maximise the uptake potential of this carbon reduction innovation across the offshore wind sector.

 

“The charging buoy tackles a multitude of problems; lower emissions, offering a safe mooring point for vessels, better power efficiency and eliminating engine noise,” said Jonas Munch Agerskov, Managing Director for Offshore Renewables at Maersk Supply Service.

 

“This is also a solution that can be implemented on a global scale, and one that can be adapted as the maritime industry moves towards hybridisation and electrification.”

 

“Ørsted has set the ambitious target of having carbon neutral operations in 2025, which includes the operations of our offshore wind farms,” added Mark Porter, Senior Vice President and Head of Operations at Ørsted Offshore.

 

“We are happy to team up with Maersk Supply Service to test this innovative charging buoy, which brings us a step closer to creating a world that runs entirely on green energy.”

For the demonstration phase of the project, Maersk Supply Service has received one of the largest EUDP grants (Energy Technology Development and Demonstration Programme, under the Danish Energy Agency) in 2020 supporting with DKK 22 million (USD 2,365,591) to the engineering and demonstration of the power buoy.
