Maersk Supply Service A/S, a part of A.P. Moller-Maersk, and Ørsted have joined forces to test a prototype buoy that will act as both a safe mooring point and an alternative maritime power (AMP) charging station for vessels.
In a statement the company said the buoy will initially be used for offshore wind farm service vessels but if successful will be utilised in a wide range of vessels, including containerships. It will be tested on Ørsted’s offshore wind farms in 2021 where it will supply overnight power to a service vessel.
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. By substituting fossil-based fuels with green electricity, virtually all emissions are eliminated while the buoy is in use.
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, according to Maersk Supply Service A/S.
This will happen through displacing tens of thousands of tons of fuel consumed every year in the wider maritime sector by enabling inactive vessels to turn engines off and replace energy consumption and charge batteries with renewable electricity.
Within five years of global operation, Maersk Supply Service aims 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.
As large parts of the global maritime fleet are getting ready to receive shore power in ports, timing is right for implementing this clean ocean-tech innovation. The charging buoy is applicable as a mooring point outside ports, in offshore wind farms, and near vicinity to other offshore installations. Additionally, it will further help limit the increasing vessel congestions and remove air pollution in port areas.
Jonas Munch Agerskov, Managing Director for Offshore Renewables at Maersk Supply Service said: “The charging buoy tackles a multitude of problems; lower emissions, offering a safe mooring point for vessels, better power efficiency and eliminating engine noise.
“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. Technical and commercial innovation is central to Ørsted’s ability to provide real, tangible solutions to achieve our operational ambitions – and we need our partners’ support.
Mark Porter, Senior Vice President and Head of Operations at Ørsted Offshore, also commented: “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 ($3.5 million) to the engineering and demonstration of the power buoy. The Danish Maritime Fund has provided initial co-financing to conceptualise the project.
