Arrays of floating offshore wind and marine renewable energy devices may create a web of mooring lines, anchors, and export cables that can cause larger animals such as marine mammals to feel trapped or disoriented. These animals may be at higher risk of predation while trapped and may injure themselves in panic. Entrapment is distinct from the concept of entanglement. Typical mooring systems do not have any loose ends, so entanglement is not possible unless derelict fishing gear were to wrap around mooring lines or cables and entangle marine animals.
