Battery Powered Offshore Supply Vessels
Offshore Supply Vessels often help port services to transport certain services to specific and often near-port destinations, for example, to shuttle food and personal services to an oil rig. They can also assist off-shore projects by carrying materials to offshore wind farm constructions.
Maersk Supply Services is installing a container shaped battery system (a hybrid battery/energy storage system) to one of its supply vessels by early next year. It is intended to eliminate fuel consumption on the vessel by 15%. Maersk's overall plans are to reduce 50% of carbon emissions by 2030.
This system will be used primarily on Platform supply vessels (PSV) but there are also aspirations to use them more broadly on Anchor-Handling Tug Supply (AHTS) vessels.
Platform supply vessels (PSV) are ships specifically designed to supply offshore projects, such as oil and gas rigs, or wind farm projects. These ships are compact in size - about 50 to 100 metres long (160 to 330 ft). The primary function of most of these vessels is logistics support/transportation of goods, such as material to build the project. In the case of a wind farm project, the vessel carries poles, propellers for the windmill, tools, equipment and personnel to and from offshore platforms and the port.
Anchor-Handling Tug Supply (AHTS) vessels are built to handle anchors for windmill or oil rigs, tow them to locations, and use them to secure the rigs in place.
The PSV pictured was converted to a wind farm service vessel. An offshore crane was added, together with a new walkway system for the transportation of wind turbines.
