Milestone Achievement: Tekmar Energy and RYDER Support Successful Installation of Over 200 Miles of Inter-Array Cables on Dogger Bank A

30/07/24

In a significant milestone for offshore wind energy, over 200 miles (328 km) of 66KV inter-array cables have been successfully installed on Dogger Bank A. The operation, which saw cables laid by DEME Offshore’s Viking Neptun and buried by the Living Stone, represents a key advancement in constructing the world’s largest offshore wind farm.

This network of 95 cables, some stretching up to 8.6 miles, links Dogger Bank A’s 95 Haliade-X 13MW turbines to the offshore converter station. From there, electricity is converted to direct current and transmitted to the onshore converter station via an advanced HVDC system. The successful installation followed extensive underwater surveys to secure a clear cable laying corridor.

Tekmar Energy played a pivotal role in this project by providing the essential cable protection systems (CPS). These systems are crucial for shielding the inter-array cables from physical damage, ensuring their reliability and longevity. Tekmar Energy’s innovative CPS technology is fundamental in maintaining the integrity of these cables during installation and throughout their operational life.

Furthermore, Tekmar Group business unit, RYDER, supported the dynamic analysis and geotechnical design for the project. This technical analysis and design work ensured that the cables were optimally installed and protected, taking into account the challenging offshore conditions. RYDER’s expertise in offshore engineering consultancy services has been integral to the project’s success.

The cables were manufactured by Hellenic Cables under a contract with DEME Offshore. This achievement is a significant milestone in the ambitious inter-array cable installation program, the largest of its kind in offshore wind energy to date.

Marc Bell, Managing Director at Tekmar Energy, expressed his pride in supporting the Dogger Bank project and highlighted the successful partnership: “We are incredibly proud to support the Dogger Bank Wind Farm with our advanced cable protection systems. This project showcases our commitment to innovation and excellence in the offshore wind sector. The successful completion of this phase is a testament to our strong partnership and collaborative effort.”

Fraser Gibson, Managing Director of RYDER, also emphasised the importance of their contribution: “Our team at RYDER is delighted to have supported the critical dynamic analysis and geotechnical design for the Dogger Bank project. This work underscores our confidence in our technical capabilities and our commitment to delivering high-quality solutions in offshore engineering. RYDER’s offshore engineering consultancy services are designed to ensure the success and integrity of such ambitious projects. We are excited to see the successful implementation of our designs and look forward to contributing to future phases.”

The completion of this phase establishes a strong foundation for the subsequent phases of Dogger Bank B and C, underscoring the dedication and expertise of all involved parties.
