CF16539GG 1 Pelamis WEC technology - Features PELAMIS Features � Offshore deployment � Inherent survivability � Highest power capture/unit weight � Available technology � INDEPENDENTLY VERIFIED � Forecastable output � Negligible visual intrusion � Minimal environmental impact � Minimum on-site construction work � Off-site maintenance 4
CF16539GG 1 5 Experimental and numerical modelling
CF16539GG 1 Pelamis WEC technology – SURVIVABILITY � Small cross-section, finite length, streamlined form, compliant moorings � Self-limiting ‘ hydrostatic loading ’ => limits absorbed power in large waves � Almost invisible to ‘ hydrodynamic loading ’ in large seas � Too short to react against extreme storm waves 6
CF16539GG 1 7 Extreme ‘100 year’ wave – 28m wave height
