Mooring systems have been extensively used in the maritime and O&G industries for decades.  Today floating marine energy converters (MECs) are growing in popularity amongst researchers, developers and investors.  The first floating windfarm, Hywind Scotland, is in construction showing that technology once confined to research and development is ready to unlock expanses of ocean for generating renewable power.  At the same time wave and tidal devices are successfully being developed and tested at dedicated sites around the world.  The future also sees large scale fish farms developed in offshore, harsh environments.


In all cases ensuring mooring system reliability is a challenge.  In O&G, over the last 10 years there have been several multi-million-pound failure incidents of mooring systems for floating production units (FPUs).  We are now seeing more ageing assets and proposed re-use of mooring chains from decommissioned rigs.


This talk will provide mooring line failure statistics in O&G; why incidents occur and where is the mooring system most vulnerable.  We will then step through the mooring integrity management lifecycle approach; a mechanism for understanding the risk profile of a mooring system and ensuring that it is appropriately specified, designed, tested, installed and maintained.  This recipe for evaluating and minimising risk will be applied to floating MECs and specific integrity considerations discussed.
