Sarens has announced that all the monopiles for the 882MW Moray West offshore wind farm in Scotland have now been installed.
Ocean Winds awarded SarensPSG the contract to provide the intermediate delivery base services for the Moray West monopiles.
Sarens PSG is a JV between Sarens and PSG Marine & Logistics.
The manoeuvres undertaken by SarensPSG took place in the port of Invergordon and involved the marshalling of 62 monopiles, each weighing up to 2000 tonnes, the largest and heaviest XXL monopiles ever to be handled in the UK, with diameters reaching up to 10 metres and a length extending to 84,7 metres.
That stage was recently completed using a self-propelled modular transporter (SPMTs) of 166 axle-lines, marking an important milestone in the UK’s transition towards sustainable energy, Sarens said.
Despite facing adverse weather conditions, including particularly wet and snowy periods during the winter, the team managed to maintain the optimal ground conditions to uphold operational integrity.
The mobilisation and demobilisation of equipment, spanning approximately three weeks each way, demanded detailed coordination and execution, according to the company.
Moreover, the construction of soil bunds for monopile storage, a key element of SarensPSG Scope of Work presented a significant mobilisation effort, extending over 2-3 months.
The SPMT configuration comprised two sets of 80 axle-lines each, complemented by a 6-axle setup for smaller components.
The selection of this equipment was determined by its flexibility, enabling seamless transport and handling operations throughout the project, Sarens added.
To handle the huge monopiles, the crew also devised strategic storage arrangements and sequencing methodologies to ensure efficient access to the monopiles during load-out.
Steve Clark, managing director of SarensPSG, said: “SarensPSG has unparalleled expertise, innovation, and commitment to drive positive change in the renewable energy landscape.
“As the industry continues to evolve, SarensPSG remains at the forefront, proving to be the ‘Sustainability Accelerator’.”
