Langlee Wave Power
The Langlee Wave Power concept, 
Langlee E2, is a floating OSWC envisa-
ged to be operating in the nearshore. 
The device is as most other OSWCs 
a hinged panel type device where the 
distance between the panels will be 
designed to be half the typical wavel-
ength of the site. The panels at each end 
will then swing in opposite direction to 
minimise tension in the moorings.
The flaps pump hydraulic 
fluid that drives the PTOs, 
which are located in the 
pillars. 
The concept has been tested 
in the Aalborg University, 
and the Trondheim Univer-
sity wave basins. 
Fred Olsen
The Fred Olsen has previously develo-
ped a multi point absorber rig called 
FO3. This project is however now ter-
minated and the efforts are now focused 
on a single point absorber device called 
the Bolt. 
The previous concept was left after 
refined calculations showed that the 
envisaged installed capacity of the FO3 
was around 3 times too large.
Concerning this new Bolt 
device there is not much 
published and e.g. the PTO 
solution is therefore unknown 
to the author. 
The 5,15 m in diameter and 
1,45 m high buoy weights 
around 6 tonnes and will have 
a rated capacity of 45 kW.

Wave Energy
The Sea-wave Slot-cone Generator 
(SSG) is an overtopping concept propo-
sed in three different WECs, one ons-
hore, one breakwater, and one offshore 
device. 
Depicted on the right hand side is the 
breakwater concept. 
The company WAVEenergy is based 
outside Stavanger in Norway and was 
founded in 2004. 
Since then the PTO technology has been 
tested in the company’s in-house wave 
tank and at Aalborg 
University in Den-
mark. 
Wave Energy is cur-
rently investigating po-
tential sites suitable for 
full-scale demonstra-
tion of the breakwater 
concept.
