ScottishPower Renewables UK Limited (SPR)
is developing the world’s first tidal power
array in the Sound of Islay, on the west coast
of Scotland. The array is to consist of ten
1MW tidal turbine generators (TTGs) and will
be classed as a “Large Power Station” in grid
terms, requiring compliance with the Grid
Code.
The array is located in the Sound of Islay, off
Port Askaig, in the channel of water which
separates the islands of Islay and Jura on
Scotland’s west coast.
UK’s first wave farm
The array of ten 1MW ANDRITZ HYDRO
Hammerfest (AHH) tidal turbines will be
installed on the seabed at depths of around
50 metres.
These turbines are fixed to the seabed and
are of horizontal axis, three-bladed design;
similar in arrangement to a wind turbine. The
TTGs shall be connected to the Distribution
Network Operator’s (DNO) network at 33kV
via one metering circuit breaker.

Foundation design
The scheme is jointly funded by the
government, the South West Regional
Development Agency (SWRDA) and the EU,
and will be the UK’s first offshore facility for
demonstrating a commercial-scale wave
power plant.
Wave Hub is described as an electrical ‘socket’
on the seabed connected to the national grid
via a subsea cable.
The completion of the £30m project will result
in it being the world’s largest wave energy
farm, with an initial capacity of up to 20MW
and a possibility of this being upgradeable to
48MW.
The scope of the project was considerable,
taking in responsibility for the overall design
of the system, including subsea cables,
connections, transformers, grid connections,
and procurement, fabrication management,
and project management on behalf of the
SWRDA.
In addition to the energy produced by the
project, it is expected to provide important
technological research outcomes for the
rest of the industry, particularly with regard
to larger scale projects, and foster local
expertise and growth in the renewable
energy industry in the south west.
The development is a groundbreaking wave
energy project off the south west coast of
England, approximately 10 miles from the
coast of Cornwall. With water depths ranging
between 48m and 58m, the site is considered
to have one of the best wave climates in
Europe.

the mouth of the Firth.
Wood Group Kenny
As part of an internal research and
technology development programme, Wood
Group Kenny conducted an in depth study
on tidal array energy yield, based on real
device data and with input from marine energy suppliers. Particular focus was placed on
the effects of wake and shield to
demonstrate the capability for complex
analysis related to the optimisation of an
array.
By applying the findings of this rigorous
research to existing knowledge, we are set to
enable significant further development in the
accuracy of yield predictions for tidal farms.
We foresee significant benefits for the
industry and our potential clients, including:
•
A capability of modelling and analysing
the wake and shielding associated with
tidal devices within an array
• Knowledge of key factors influencing
wake and shielding, and an ability to
quantify the effects on individual turbines
or an array
• The ability to apply an approach to
accurately predict energy yield from tidal
devices within an array.

Due diligence and
project support
SgurrEnergy undertook a comprehensive
technical and energy forecast assessment
and due diligence of the Pelamis wave
energy device on behalf of Scottish Power,
prior to the utility making a final decision to
progress with a project to consist of four
Pelamis devices.
Our work included reviewing the resources
and capabilities of Pelamis wave power, its
capacity for supporting operational projects
in the future, and its ability for expanding
production levels. We also undertook a
detailed review of the reliability and availability
levels of the wave energy converter, and
provided our client with expert support in
assessing wave energy forecasts and device
performance analysis.
SgurrEnergy worked alongside
ScottishPower, and the Pelamis developers to
identify issues affecting the survivability of the
Pelamis wave energy converter. This project
included an assessment of the extreme
waves, sediment stability, and risk of mooring
failure, estimating extreme temperature, and
icing conditions.
Our health and safety team provided
consultancy services to Aquamarine Power’s
new health, safety and quality manager.
During an important phase in the
development of their Oyster 800 wave
energy generator, it
was essential that the handover of the health
and safety manager’s role was seamless, and
the team aided in this transition by providing
support and assistance.
Additional support included the provision of a
full health, safety, environmental and quality
gap analysis of their current processes and
procedures to offer the health, safety and
quality manager ideas and suggestions on
potential areas of improvement throughout
the operation.
