Coastal Virginia Offshore Wind (CVOW)

The CVOW project is a great example of Tekmar Group’s complementary technologies and services working together to support multiple stages of an offshore project.

Tekmar Group companies; Ryder Geotechnical, Agiletek Engineering, Tekmar Energy, and Pipeshield International all contributed to the Coastal Virginia Offshore Wind Project (CVOW) on the East Coast of the US.

The 12 MW CVOW project is the first offshore wind project in US federal waters. This significant project includes the deployment of two 6MW commercial-scale offshore wind turbines that will help to determine the best practices for future offshore wind projects located on the East Coast.

Ryder Geotechnical, who specialises in geotechnical design and analysis, was the first group company to support the project, delivering a Cable Burial Risk Assessment (CBRA) on behalf of Ørsted in 2019. The CBRA was performed during the design stage of the project to quantify the risk to the subsea export and array cables from external sources.

Tekmar Energy, who specialises in subsea protection solutions, has since supplied Seaway 7 with TekLink® cable protection systems and TekDuct cable crossing protection for the construction phase of the project. AgileTek Engineering, who specialise in advanced engineering analysis, performed product design verification analysis on behalf of Tekmar Energy.

CVOW is one of several recent contracts awarded to Tekmar Energy by Seaway 7 and marks a clean sweep for the company in the US offshore wind sector, having previously supplied cable protection systems for Block Island offshore wind farm.

Pipeshield International, who specialises in concrete stabilisation and protection solutions, was also awarded a contract from Seaway 7 to design, manufacture and supply 30 bespoke concrete mattresses and associated lifting equipment for the protection and stabilisation of subsea cables on the wind farm.  Pipeshield’s in-house technical design department has developed a solution incorporating heavy density minerals, a high-quality concrete mix, and their patented N2 edge blocks to provide the industry’s most stable mattress.
