MEMBER NEWS: Rovco awarded contract at Galloper Offshore Wind Farm

Rovco, a leading global provider of subsea robotic and hydrographic survey solutions, has been awarded a contract for the provision of offshore rock bag deployment and installation at the Galloper Offshore Wind Farm in the Outer Thames Estuary.

The project scope covers the application of an operator engineered solution for the installation of rock bags, which need to be placed at precise locations on and around the Cable Protection Systems (CPS) on the wind farm, located 27km off the Suffolk coast.

Following previous subsea surveys, rock bag placement was selected from a number of options considered by the operator as the most suitable solution to eliminate or vastly reduce excess cable movement of the CPS, stabilising and prolonging the life of the array cables which carry the generated electricity from the wind turbines.

Rovco will deploy the DPII subsea support vessel VOS Star, on charter from Vroon Offshore Services, during the project. The vessel will be pre-installed with cutting-edge survey equipment and Rovco’s powerful Seaeye Leopard WROV which will be fully calibrated, and system tested for swift commencement.

The project is led by personnel from Rovco’s experienced offshore team and a dedicated onshore project manager who will be assigned to the project throughout, to ensure safe and efficient operations.

The 353MW Galloper Offshore Wind Farm has a site area of 180km2 with wind turbine generators located in depths between 26.5m-39.5m (LAT). Galloper’s 56 turbines will generate enough green electricity every year to power the equivalent of more than 380,000 average homes in the UK.

Sean Chenery, General Manager at Galloper Offshore Wind Farm said, “We selected Rovco to install the rock bag solution due to their knowledge, experience and competitiveness in subsea operations. Placing rock bags on live cables at water depths of 26m–39m with tight tolerances is where Rovco’s equipment excels.”

Simon Miller, Chief Revenue Officer of Rovco, and its sister company Vaarst, said, “Engineering solutions to extend the life of critical subsea infrastructure and ensuring uptime of these offshore assets and installations is crucial. This award by Galloper Offshore Wind Farm, to help them detect issues and implement their designed solution post engineering analysis, is testament to our team’s efforts across the company and real recognition of our growing presence in this market. We are thankful to Galloper for placing their trust in us to deliver an efficient, safe, cost-effective solution.”

“Rovco’s highly experienced team and our expertise in developing and providing subsea solutions for the offshore wind sector can help operators, detect, report, consult, design and implement mitigation programmes to limit the effects of existing issues, whilst minimising the risk of problems arising in the future and most importantly prolonging the life of major subsea components to extend operations.”

AREG is the original energy transition organisation, working on behalf of members to empower the energy supply chain and champion its expertise. Please get in touch if you have any questions or would like to find out more about membership.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.


Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.


Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
