Lifecycle support for floating wind: navigating challenges with expertise

1. Pre-feed and planning

Before breaking ground, meticulous planning is essential. Our services include:

• Mooring and cable concept screening: we assess various mooring and cable options, considering feasibility and cost-effectiveness.
• Site characterisation recommendations: understanding the environment is crucial. We provide insights into soil conditions and other site-specific factors.
• Floating hull assessments: evaluating hull designs to optimise performance.
• Preliminary schedules and pricing: early planning and budgeting ensures smooth execution.

2. Site characterisation

Accurate site characterisation is the foundation of successful projects. Our geo-services cover:

• Geophysical surveys: utilising autonomous surface vehicles (ASV), autonomous underwater vehicles (AUV), and ultra-high-resolution seismic techniques.
• Geotechnical investigations: from downhole coring to laboratory testing.
• Cable route surveys: ensuring optimal cable placement.

3. Feed and detailed engineering

Our engineering expertise spans:

• Global performance assessment: a rigorous review of mooring and anchor options.
• Cable lay analysis: ensuring viable cable layout.
• Risk assessments: identifying and mitigating potential challenges.
• Digital twin: creating a virtual model for real-time monitoring.
• Installation engineering: precise procedures for seamless execution.

4. Mooring provision

To secure floating wind platforms, we customise mooring solutions based on project requirements:

• Drag and plate anchors: robust anchoring systems for station-keeping.
• Suction, driven, drilled, and grouted piles: tailoring foundations to soil conditions.
• Chain/wire/fibre rope: versatile options for varying depths.
• Connectors: ensuring reliable connections.
• Buoyancy and clump weights: balancing buoyancy and stability.
• Tensioners: ensuring optimal tension.

5. Marine operations

Efficient marine operations are critical. Our services include:

• Quayside and nearshore movements: safe handling during assembly and deployment.
• Offshore pre-lay mooring: precise positioning before installation.
• Nearshore and offshore towing: transporting offshore floaters with care.
• Optimised array cable layouts: streamlining cable networks.
• Experienced marine personnel: skilled professionals for seamless execution.

6. Monitoring and inspection

Ensuring project integrity through:

• Sensors and monitoring systems: real-time data for performance assessment.
• Corrosion prevention: protecting against environmental factors.
• Integrity engineering services: detecting anomalies and ensuring reliability.
• Digital response twins: virtual models for predictive maintenance.

7. Repair and maintenance

Minimising downtime with:

• Emergency response planning: ensuring swift action during unforeseen events.
• Disconnect and tow procedures: safely managing maintenance.
• Mooring line and cable repairs/replacements: ensuring continuous system reliability.

8. Decommissioning

A well-executed end-of-life process involves:

• Unhooking and recovery of mooring lines: safely disengaging from the seabed.
• Towing to shore: efficient retrieval of floaters.
• Cable recovery: retrieving valuable assets.
• Cutting services: removing subsea infrastructure.
• Site surveys: assessing environmental impact.
