Project Summary
TADEK and Tardra collaborated to develop a robust mooring solution for a floating offshore wind development, progressing from conceptual anchor design and geotechnical assessment through to installation methodology, vessel selection, commercial evaluation and operational risk assessment.
The Challenge
Significant geotechnical variability across the site required a flexible yet practical anchoring strategy.
- Soil conditions varied significantly across the development area
- Multiple anchor concepts required evaluation
- Full field installation needed to minimise anchor types
- Equipment and vessel spreads required optimisation
- Installation strategy needed to support a simple commercial T&I model
TADEK‘s Role
TADEK supported the engineering and operational definition of the mooring system.
- Evaluated anchor concepts including driven and drilled piles
- Assessed installation vessel spreads and deck layouts
- Developed operational installation sequences and storyboards
- Performed commercial and operational risk assessments
- Supported integration of engineering with project delivery strategy
Our Approach
A staged engineering approach combined geotechnical assessment, installation planning and market analysis.
- Assessed soil conditions to identify viable anchor solutions
- Defined installation spreads and offshore support requirements
- Applied combined installation strategies across anchor types
- Evaluated vessel availability and market readiness
- Aligned engineering with commercial and contractual considerations
Outcomes
The study delivered a clear pathway for practical and commercially viable mooring installation.
- Anchoring strategy aligned with variable site conditions
- Installation methodology based on proven vessels and equipment
- Reduced project risk through simplified anchor typologies
- Commercial dossier prepared for developers and T&I contractors
-
Increased stakeholder confidence in project constructability
