The SeaWEED wave energy converter generates electricity by floating on the surface of the ocean and riding over the rising and falling motion of waves, and has the power capacity of 750 kW.
Each SeaWEED unit consists of four modules that are connected by truss structures.
The four module array includes a non-energy producing nose module in the front, followed by two energy producing modules, with another non-energy producing module at the rear.
The producing sections are 8 m wide, 5 m high, and 16 m long. The maximal overall length of the structure is 150 m. The movement of the modules rising and falling over passing ocean waves drives 4 on-board double acting hydraulic rams that feed electrical generators, which in-turn generate clean renewable energy that is then transmitted to industry standard subsea hubs.
The SeaWEED is anchored to the seafloor by a mooring design which includes a three point catenary slack mooring system at the front of the device and a single leg slack mooring system at the rear.
This mooring design can be deployed by any anchor hauling vessel.
The SeaWEED can be deployed in locations with water depths of greater than 50 m.
Grey Island Energy is Canadian wave energy developer that aims to develop a proprietary wave energy device (SeaWEED) into a commercialized, patented full scale system.
Take a look at the animated video of Grey Island Energy’s SeaWEED wave energy converter producing power from the waves.
