Large marine animals, especially great whales such as grays or humpbacks, may potentially become entangled in mooring lines and power cables, resulting in drowning, or the lines may abrade the whale’s skin, allowing debilitating infections to result in injury or death. Many wave devices and floating tidal turbines are attached to the seabed with mooring lines. In addition, marine renewable energy (MRE) devices must send energy to shore through large export cables, usually placed on the seabed; cables that collect power from individual devices may be strung in the water column before joining a single cable heading to the sea floor. This summary represents a general overview of the research, produced by Annex IV under Ocean Energy Systems. The table below contains the literature relevant to entanglement and the marine renewable energy industry and will continue to be updated as new literature is added to Tethys.
