RR1095 - Guidelines for monitoring the service and behaviour of mooring systems for floating offshore installations. Mooring Integrity Joint Industry Project Phase 2

Mooring integrity for floating offshore installations is an important safety issue for the offshore oil and gas industry. This report is one outcome from Phase 2 of the Joint Industry Project on Mooring Integrity. This work ran from 2008 to 2012 and had 35 industry participants. It followed the Phase 1 work described in HSE Research Report RR444 (2006). The Phase 2 work compiled research on good practice and an overview is given in HSE Research Report RR1090 (2017).

This report provides guidelines for monitoring the service and behaviour of offshore mooring systems – the loadings and movements to which they are subjected by wind, waves, sea currents and sea levels. Monitoring is used to give confidence in the ongoing integrity and fitness of a mooring system. The report covers: the importance of identifying whether a monitoring campaign or installation of a permanent monitoring system is required; minimum requirements for different types of monitoring scenarios; options for monitoring methods; and data management.
