23 Degrees Renewables and SEAJET complete cable burial campaign for Nexans

OEG Renewables announce that two of the businesses within its cables service line, 23 Degrees Renewables and SEAJET have successfully delivered a turnkey cable burial campaign for Nexans, a leader in the design and manufacture of cable systems and services.

OEG Renewables, a division of OEG Energy Group Limited, is pleased to announce that two of the businesses within its cables service line, 23 Degrees Renewables and SEAJET Systems (“SEAJET”) have successfully delivered a turnkey cable burial campaign for Nexans, a leader in the design and manufacture of cable systems and services.

SEAJET utilised their innovative all-electric controlled flow excavation (E-CFE®) technology called HYDROMOLE to execute the work scope, which included trenching and burial of shallow water export cables at an offshore wind farm site in the UK.

The advanced control system built into HYDROMOLE, allows performance to be monitored and optimised in real-time, ensuring reliability and maximising project uptime. Other major benefits include vastly reduced CO2 emissions, eliminating the risk of high-pressure, high-volume oil spills into the marine environment and reduced noise pollution.

Geir Korstad, Project Manager at Nexans commented: “There is no doubt that the HYDROMOLE is a very powerful tool, and we are extremely impressed with the burial results from this campaign. The environmental benefits of the HYDROMOLE were greatly appreciated and the SEAJET team were highly skilled and professional in successfully delivering the project for us.”

The HYDROMOLE was deployed from an ultra-shallow draft multicast vessel for completion of the work scope. The compact deck space onboard the vessel allowed SEAJET to demonstrate the adaptability of the equipment spread, which was easily accommodated onto the vessel deck which had limited available space.

The project offered challenges with regards to the operational conditions; presenting tight weather windows to conduct work within, and aggressively fluctuating tidal ranges. The specialist SEAJET team, who are experts in working in these challenging shallow water conditions, successfully demonstrated that the HYDROMOLE system delivers up to 100% more power than any legacy hydraulic CFE systems currently on the market, even when presented with some of the most challenging conditions considered for this type of seabed intervention works.

Faisel Chaudry, Managing Director of SEAJET, said: “The SEAJET team has over 20 years of operational experience with traditional hydraulic CFE systems, and we have never seen a CFE system deliver such high performance results as this, which was particularly impressive given the challenging shallow water environment with a high tidal range. Our clients are now seeing the benefits of our HYDROMOLE system, which offers unparalleled power, and highly acclaimed health, safety and environmental advancements, and we are delighted to have delivered such a successful work scope.”

David Carr, Chief Commercial Officer of OEG Energy Group, and Director of OEG Renewables’ Cables division, added: “We are thrilled to have successfully delivered this integrated solution, providing excellent results for our customer through leveraging the combined strengths, capabilities and technological expertise from two OEG Renewables businesses within our cables service line.

“SEAJET is just the latest technology company that we have invested in and nurtured with the intent of developing a stronger UK supply chain creating highly skilled jobs and cutting edge British designed and built innovative solutions for the offshore renewables sector.”
