Offshore devices are generally floating structures moored to the seabed that operate in deep waters to take advantage of the larger wave resource. While there are many different concepts, as yet, there is not a clear leading technology. Several small scale models have been tested in the sea, as well as a handful of full scale prototypes.
The advantage of offshore devices is that they have access to more powerful waves. As waves pass into shallower water, energy is lost through interaction with the sea bed. However, the deeper offshore waters cause greater difficulties for grid connection and the mooring of devices, as well as being harder to access for maintenance.
