There were numerous offshore wind industry leaders in attendance – including sales partner Tekmar Energy Limited, DONG Energy, VBMS, Jan de Nul, and CWIND. The event was held at The Underwater Centre near Fort William in Scotland and involved a full scale demonstration of the installation and removal of a CPS from mock-up offshore foundations.
Cable protection systems are designed to be maintenance free for the full service life of the windfarm. However, for decommissioning purposes and in order to reduce risk within the industry it is important that any equipment that is installed subsea has a proven and robust method of removal.
The Underwater Centre provided a Workclass Remotely Operated Vehicle (WCROV) which was launched from an offshore vessel and carried out the operations in Loch Linnhe which is a seawater lake.
The demonstrations were carried out over a two day period. On the first day the removal operation was performed on a mock-up j-tubeless monopile foundation, whereas the second day was reserved to carry out the same operation on a mock-up j-tube. Both demonstrations were considered successful with operations being completed considerably quicker than expected.
