AMEC is part of a consortium setting up wave power trials in Scotland to see if renewable energy has commercial potential.
A full-scale trial is being set up at the Marine Energy Test Centre in Orkney and the units will start producing energy this summer.
Amec spokesman Alastair Rennie said: 'This will allow us to see the technical and commercial potential of the technology and, if commercially acceptable, could pave the way for large-scale application of this environmentally friendly source of energy.'
The project is known as Pelamis which is Greek for sea snake. It consists of four 24 m canisters which sit perpendicular to the waves and generate electricity from the motion between their flexible joints.
Amec is in a joint venture with ScottishPower and Ocean Power Developments.
