Abstract

This paper presents an investigation of the impact of mooring line slackening due to additional inverse catenary cut-in imposed by severe loading conditions on the offset integrity of a deep water floating production unit. The slackening in the moorings may be caused by the action of extreme loading conditions such as hurri- canes, or by tensioning the catenaries to load levels higher than those occurring during the installation phase. The assessment presented here considers how this change in the inverse catenary affects the behaviour of the mooring.
