MEMBER NEWS: Rovco wins survey contract with Flotation Energy for Cenos floating offshore wind farm

Rovco, a global provider of technology-enabled project solutions to the offshore renewable energy sector, has been contracted by Flotation Energy to carry out a geo-environmental survey at its planned Cenos floating offshore windfarm, 200 kilometres off the north-east coast of Scotland.

Located in the Central North Sea, the 1.4GW Cenos floating wind development will cover approximately 333km2. Rovco, having recently launched a dedicated marine site characterisation business line, will deploy its multi-purpose, custom-reconfigured DP2 survey vessel, the Glomar Supporter, to carry out the work.

It is expected that the project will comprise subsea studies of the floating wind turbine generators, mooring line anchor locations, inter-array cables, fixed foundation substation areas, and the portion of export cables that fall within these locations.

Rovco’s scope of work involves the acquisition of geophysical and benthic information to provide detailed data to inform environmental impact assessment (EIA) consents and the engineering processes from engineering to early front-end engineering and design (FEED) study.

The geophysical element of the workscope requires the acquisition of multi-beam echo sounder, side scan sonar, magnetometer, sub-bottom profiler, and multi-channel seismic data along with associated analysis, processing, interpretation, and reporting.

Flotation Energy’s partner on Cenos is Norwegian-offshore wind company, Vårgrønn; a joint venture between energy company Plenitude (Eni) and investor HitecVision. The joint venture secured a lease earlier this year as part of Crown Estate Scotland’s INTOG (Innovation and Targeted Oil & Gas) round.

Craig Davis, Director of Site Characterisation for Rovco, said: “We’re extremely pleased to be working with Edinburgh-based Flotation Energy on this project. The company has been a significant contributor towards the building of a strong offshore wind industry in the UK and beyond.

“Our dedicated site characterisation division was launched specifically to provide the full range of survey solutions to offshore wind projects such as Cenos, in order to take it from pre-construction to first energy as swiftly, efficiently, and cost effectively as possible. Having access to the full range of tools, equipment, and technology on the Glomar Supporter, along with our highly experienced and specialist team, will be instrumental in helping Flotation Energy meet its timescale for this project utilising a local supply chain partner.”

Dan Wright, Supply Chain Manager at Flotation Energy, commented: “Having secured Rovco’s extensive offshore renewables experience to support the subsea studies will add immense value to our Cenos project and also reaffirms our commitment to building a robust local supply chain for our offshore wind projects. By focusing our efforts on creating flexible and collaborative partnerships with Scottish-based companies such as Rovco, we can provide opportunities to establish a floating wind supply chain ready to deliver for Scotwind licensing projects and beyond.”

“The successful delivery of our survey campaign with Rovco enables us to maintain our fast-track delivery schedule for Cenos, a project that will decarbonise North Sea oil and gas assets and remove over 2 million tonnes of CO2 a year, helping to support Scotland towards its 2045 Net Zero targets.”

Launched at the turn of the year, Rovco’s marine site characterisation business unit was established to help address a critical industry shortage of companies with the all-round capabilities and expertise to support a rapidly emerging market during the earliest phases of offshore wind farm development.

At its heart is the multi-purpose DP2 survey vessel, Glomar Supporter. On long-term charter from Glomar, the vessel underwent an extensive rebuild and refurbishment in 2021 and has been reconfigured to permanently carry an entire suite of state-of-the-art survey sensors and equipment, aimed at providing the highest quality data capture, reporting and technology-enabled solutions for a streamlined and efficient site characterisation offering. This package offers complete flexibility while on site, to adapt and respond to different challenges in a single offshore trip.

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.
