The Pull and Lock Marine (PALM) connector proposes robust, reliable and repeatable connections of the Wave Energy Converter (WEC) in a short, simple marine operation.
The PALM is based around a submerged buoy mooring with an integrated electrical riser. Tugs are used to position the WEC, engage the PALM and complete the mechanical and electrical connection. The core innovation is the design of a formed plug component and catcher arm. Coarse and fine guide slots ensure tight alignment, so that electrical connection can be completed simultaneously. The resulting linkage is fully articulated, while riser tension ensures continuous connection in all sea states. Disconnection is effectively the reverse of the connection operation.
All components are based on proven marine technology. The number of moving parts is kept to a minimum, and load-bearing components are rugged.
