Short Science Summary: Entanglement with Marine Renewable Energy Mooring Lines
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. The Entanglement Short Science Summary was developed based on the Annex IV 2016 State of the Science and represents a general overview of the research, produced by OES-Environmental under Ocean Energy Systems.
