Teesside

Background

Teesside Offshore Wind Farm is located off the North East Coast near Redcar in Cleveland, and has been operational since 2013 with the capacity to generate up to 62.1 MW of low carbon electricity.

EDS’s involvement

EDS was selected from many by energy company EDF Energy Renewables (EDF-R), to provide the Technical and Safety Representative during the completion phase of this project. EDS was also awarded a three-year contract for operations and maintenance (O&M) management of the High Voltage Network at Teesside Offshore Wind Farm.EDS was awarded this contract following a competitive tendering process involving three other major players in the sector, and are responsible for the operations and maintenance (O&M) of the High Voltage Network at the windfarm, with Teesside under the remit of the EDS’s 24/7 Control Centre.

Tap Changer Maintenance

In 2018, as part of EDS’s planned preventative maintenance programme for the HV network, EDS HV successfully completed on-load tap changer maintenance work on Teesside’s 66kV/33kV generator transformers.

As industry experts will know, tap changer maintenance is a very complex and intricate operation and EDS were happy to provide the high level of skills that are required for such an operation.

Ryan Murphy, EDS’s Asset Manager said:

“Our planned preventative maintenance programme for the generator transformers at Teesside indicated that the condition of the oil within the tap changer compartments was deteriorating. EDF-R, recognising the criticality of their transformers were very proactive in bringing us in to carry out this work.”

“At EDS, we pride ourselves on having highly skilled resources in-house to carry out such tasks, enabling us to provide an excellent and efficient turnkey solution to the client.”

Lincs

BACKGROUND

Lincs Offshore Windfarm is situated 8km off the east coast of England.
Consisting of 75 turbines, it was officially opened in 2013.

EDS`S INVOLVEMENT

EDS were once again selected on the basis of cost, competency and reputation
to provide the skilled Engineers to carry out the termination and testing of the 132kV
export cable on the OSP at this site. As a result of this work being carried out on
time and to budget, and as recognition of the dedication and experience of the people
involved, EDS was then invited to submit documentation to complete a string of turbines
to termination and testing level. This was required on an urgent basis as time was in
very short supply and the project, already running late was at risk of not hitting the
`turn on` date. We submitted the bid and were once again chosen as the partners
of choice for the task. The task was completed in the timescale submitted and as
a result of EDS intervention the `turn on` date was achieved. our performance was
described as `exemplary` and our approach as `prompt, accurate and succinct`.

Robin Rigg

BACKGROUND

Robin Rigg wind farm is located in the Solway Firth on the Scottish side of the Scottish/English Border. One of the first major offshore windfarms in the UK, it consists of 60 turbines that produce enough energy to power nearly 120,000 homes.

EDS`S INVOLVEMENT

From the first fault & emergency call, EDS were able to mobilise a team of experts and get to site within 12 hours. Initially offshore access to the substation platform wasn’t available due to poor weather, but as soon as they were able to get out, EDS quickly located the fault using their innovative new fault finding equipment in addition to traditional fault location methods.

Delighted to showcase their turnkey solution, EDS planned the job from start to finish in close liaison and with the consent of Transmission Capital (the OFTO) and E.on the owner of Robin Rigg Offshore Windfarm. After finding the fault they were able to excavate the area, source the materials quickly (an almost impossible task, but helped by the fact that EDS have excellent relationships with their suppliers), plan and carry out the repair, and then test before re-energisation. Remarkably, all this took place in just 12 days, despite the first 2 days being lost to poor offshore weather, and atrocious wet weather conditions for the rest of the time.

Blyth Offshore Wind Demonstrator Project

EDSHV Group choosen by VBMS to carry out cable termination and testing at Blyth Offshore Wind Demonstration Project

Background

Blyth Offshore Demonstrator wind farm (BOD), located 5.7km off the North East coast currently comprises of 5 turbines, although it has consent for up to 15 turbines when fully constructed.

The BOD project has enabled owner and developer, EDF Renewables UK, to trial new technology and it is the first offshore wind farm to be built upon gravity-based foundations. Importantly, BOD is also the first offshore wind farm to use a 66kV cabling system. This is a critical development for the industry which will lead to more cost-effective power collection and transmission to shore, as well as being a crucial development in the push to continuously reduce the Levelised Cost of Energy (LCOE).

EDS’s Involvement

EDS were chosen by VBMS (now Boskalis) to carry out cable termination and testing at the EDF Energy Renewables (EDF ER) Blyth Offshore Wind Demonstration Project in Northumberland.

As the first in the industry to use 66kV cabling, use of this higher voltage required a much higher skill set and an experienced company such as EDS were the obvious partner.

EDS were able to provide the necessary expertise to complete 66kV terminations and testing on all 5 assets, along with fibre optic termination and testing.

Ken Ritson, group managing director of EDS said:

“EDS was delighted to be chosen to assist EDF Renewables UK in the commissioning of this landmark project. We believe that 66kV will quickly become the industry norm and we are pleased to offer the necessary level of competence and experience required to manage this change within the industry.”
