The electric power produced by offshore wind turbine generators (WTG) needs to find it’s way to the main land through electric power cables, connecting the WTG to the offshore substation (OSS) and the OSS to the main land. These thick and heavy cables are transported close to the structures by means of an installation vessel. By diverting an extra length of cable over a cable deployment bow, also called a quadrant, the vessel can maintain a safe distance to the connection point, thus preventing accidental damage.
