Intermoor completes studies for floating windfarm in Aberdeen, Scotland

Intermoor, Acteon's Moorings and Anchors business line, is pleased to announce the successful completion of multiple study packages for the planning, installation, operations, and maintenance of a commercial-scale floating windfarm in the United Kingdom. The windfarm, with a capacity of up to 1GW and water depths ranging from 85 m to 150 m, represents a significant advancement in renewable energy.  

The completed studies include:  

1. Mooring system costs and installation comparison study

• Evaluated equipment procurement, vessel requirements, installation methodology and installation costs for 25 Floating Offshore Wind Turbine (FOWT) units.
• Assessed drag anchor feasibility for six mooring configurations, including catenary and semi-taut systems.
• Developed method statements for pre-installation of anchors, anchor test tension, polyester pre-stretching and FOWT hook-up options.  

2. Mooring repair and sparing philosophy study

• Analysed repair strategies and sparing philosophy for six FOWT mooring systems covering hybrid catenary, semi-taut, and taut configurations.
• Reviewed historical data to identify probable mooring component failure modes.
• Developed sparing philosophy for each mooring system component.  

3. Port facilities study: FOWT mooring storage and mobilisation

• Assessed storage, handling and mobilisation methodology for each mooring component.
• Developed delivery and installation schedules and prepared indicative operational costs to meet annual demand for up to 20 FOWT units per year.
• Developed port facility specification for various mooring configuration scenarios.
• Evaluated local port facilities against specified requirements.

4. Anchor feasibility study

• A feasibility study in relation to selection, fabrication, and installation of anchor solutions for a UK-based floating offshore wind farm with anchor loads in the range of 1000 t to 2000 t

5. FOWT temporary mooring study

• Proposed technical solutions and cost estimates, considering preliminary temporary mooring design, indicative anchor design, installation/hook-up methodology and estimated costs for temporary mooring of FOWT foundations.

These studies position Intermoor at the forefront of floating offshore wind development, driving innovation and efficiency for our customers.
