The company has initially installed the wave buoys in December 2013 and removed them from site for a few weeks in the summer to allow for battery replacement and maintenance.
Pelamis crew has returned them to site this week in conjunction with the Environmental Research Institute based in Thurso.
The company has also installed an Acoustic Doppler Current Profiler at the site, which will provide an understanding of currents in the area.
Pelamis is developing an offshore wave energy farm of about 10MW to prove the Pelamis wave energy converter in a commercial demonstration project.
The Farr Point project is an Official Competitor for the Scottish Government’s Saltire Prize, an international challenge for the marine power sector.
An ‘Area of Search’ is situated about 5km to 12km off the Sutherland coast, with flexibility to take into account other sea users, survey data and environmental data before defining the final site location.
A Pelamis wave farm of 10MW size would occupy a much smaller area of 2km² to 3km².
The project will feature about 10 Pelamis wave energy converters, in an array layout.
Electricity from the array will be exported to shore through a single subsea cable to a substation at an onshore landfall point on the north coast for connection into the mainland grid.
