Calling for entries from companies and consortia interested in undertaking a study to establish an evidence-based understanding of the environmental and sustainability performance of synthetic mooring ropes across their life cycle, supporting informed decision making for floating offshore wind deployment.

The Floating Wind JIP would like to determine the impacts of fibre ropes as a sustainable solution for mooring systems and if further research is required to understand their impact over their life cycle by:

• Understanding Degradation and environmental release: Assess expected rope degradation over the project lifetime, the factors driving it, and the potential release of microplastics, coatings or additives. Where feasible, this should consider whether indicative release rates and potential quantities can be estimated to support shared understanding and informed engagement between developers, regulators and statutory nature conservation bodies.
• Manufacturing considerations and sustainable material alternatives: Assess waste and energy requirements from raw material production and rope manufacturing, including the feasibility of bio based, biodegradable or recycled material alternatives. This should consider whether such materials can meet the durability, creep resistance and fatigue life required for commercial floating wind mooring systems.
• Approaches to end of life and recycling: Feasibility of closed loop recycling, including material recovery, reprocessing, and reuse.

The deadline for clarification questions is 30 July 2026.

The closing date to receive tender submissions is 17:00 BST 20 August 2026.

All clarification questions and tender submissions should be sent electronically, by their respective deadlines to michael.archer@carbontrust.com, with floatingwind@carbontrust.com in copy.
