4Subsea has been awarded a project under the DeepStar® consortium to develop a guideline for monitoring of polyester mooring lines used in deepwater floating systems. The project will support the establishment of best practice for integrity monitoring, contributing to safe operations, reduced risk and improved design verification.
The guideline will address what to monitor, how to monitor it, and how to interpret monitoring data for polyester mooring lines. The work is based on operator needs and operational experience and includes data quality and analytics, best-practice monitoring strategies tailored to polyester rope behaviour, and model-supported evaluation using monitoring data and OrcaFlex analyses.
Peter Jenkins, CEO of 4Subsea, said: ““We are pleased to be given the responsibility of developing a practical industry guideline for monitoring of polyester mooring systems, supporting informed integrity management decisions throughout the asset life.”
Polyester lines are increasingly used in high tension mooring systems due to their low weight and fatigue performance. Their time-dependent mechanical behaviour requires fit-for-purpose monitoring to ensure long-term integrity. The guideline aims to support a consistent and practical monitoring approach, enabling early detection of abnormal behaviour and timely decision-making.
