OEG Renewables’ subsidiaries 23 Degrees Renewables and Seajet Systems have successfully delivered a turnkey cable burial campaign for Nexans.
Seajet utilised its 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 unnamed offshore wind farm in the UK.
Nexans project manager Geir Korstad said: “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 multicat 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 into the limited deck space, the company said.
The project offered challenges with regards to the operational conditions; presenting tight weather windows to conduct work within, and aggressively fluctuating tidal ranges, it added.
Seajet managing director Faisel Chaudry 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.”
