Pelamis Wave Power
Scottish Pelamis Wave Power develops 
an attenuator type WEC. 
The current machine under develop-
ment is the P2 WEC, which is conside-
rably larger than the previous P1.
The P2 is 180 m long and approx 4 m 
wide, and the device will have a rated 
capacity of 750 kW.
The PTO is hydraulic, and individual 
PTOs are located at each joint of the 
machine. 
The previous machine, the P1, was 
installed at EMEC and in Portugal was 
three P1 machines connected to 
the Portuguese national grid.
Pelamis is currently assembling 
a P2 machine for E.On that will 
be deployed at EMEC in the 
summer of 2010. 
Scottish Power has also ordered 
a P2 for an EMEC installation, 
which will be constructed after 
the final assembly of the E.On 
machine.
Aquamarine Power
Aquamarine Power, based in Edinburgh, 
develops an OSWC called Oyster. 
The hinged flaps pumps seawater to 
an onshore PTO station, which much 
resembles a hydropower plant.
The WEC system is designed for nears-
hore installation where the horizontal 
component of the water particle motion 
is larger due to the shallower water depth.
The Oyster 1 is currently installed and tested at 
EMEC.
Aquamarine Power is currently developing the next 
generation Oyster, the Oyster 2. 
The company plans to deploy three Oyster 2 units, 
connected to one PTO at EMEC 2011. This project 
is envisaged to have a rated capacity of 2.5 MW.

Wavebob
The Irish Wavebob is a point absorber 
type WEC. 
The working principle is to utilise the 
relative motion between to separate 
bodies.
One body, the Torus, rides the waves 
whilst the other, the Float-Neck-Tank 
(FNT), has a different wave activated 
response. 
The inertia of the FNT is to a large ex-
tent derived by captured water, and the 
device will be tuned according to wave 
climate by means of venting water in 
and out of the FNT. 
The PTO is based on hydraulics, and 
the envisaged nameplate capacity is 1,5 
MW. 
A 1:4 scale Wavebob has been subjec-
ted to two sea trials in Galway bay. 
A part EU funded project aims to see a 
grid-connected scale Wavebob installed 
off the Portuguese coast during the 
course of year 2011.
