This is a follow up of my previous impression a few weeks ago, concerning the development of an offshore charging station for the vessels. This was a joint venture between Maersk and Ørsted and it was called the Stillstorm. In January this year, the Maersk Supply Service partnered up with Ørsted and launched Stillstrom (‘quiet power’ in Danish) to demonstrate the world’s first full-scale offshore charging station for vessels at an offshore wind farm in the third quarter of this year. Stillstrom is owned by Maersk Supply Service and receives financial support from the Danish Maritime Fund and the Energy Technology Development and Demonstration Program (EUDP). The company is also working with offshore wind power giant Ørsted on the first full-scale demonstration of a charging buoy to power one of its service operation vessels (SOVs) overnight.
This impression is about the employment of this off shore charging station at one of the ports in Scotland. AP Moller-Maersk’s offshore charging spinout, Stillstrom, is partnering with the Port of Aberdeen on a groundbreaking project to reduce emissions from ships waiting outside the port. As part of the MoU, the partners will conduct a collective feasibility study this year with the goals of developing a roadmap for the potential introduction of offshore charging infrastructure at the Port of Aberdeen. Developed in-house by Maersk Supply Services, the Stilstrom concept provides ships with a platform to harness power from offshore wind or grid power, eliminating the need for ships to consume fossil fuels when idling. This product also allows charging of suitable vessel battery packs. The concept of off shore vessel charging was introduced by Maersk when the company said it had joined forces with the offshore wind major Ørsted to test a prototype buoy that will act as both a safe mooring point and a charging station for vessels on one of Ørsted’s offshore wind farms.
The establishment of off shore wind farms for vessel charging can be of great importance for electric vehicles that are destined for long journeys. One of the limitation of wide spread use of vessel charging was the inability to charge the batteries while at the sea as it was only possible to get the batteries charged while docked at the port. In addition to this there will be a marked reductions in the emissions of auxiliary engines as the ships will not have to turn to the engines for the provision of power when the charged batteries run out. Testing the use of these off shore wind farms at the port of Aberdeen will provide an in depth analysis of the feasibility and limitations of the incorporation of off shore wind in vessel charging.
