SUMMARY
This information sheet applies to offshore installation moorings. It replaces OTO 2001/50 on Station keeping; SPC/ENF/50 on the Reporting of Mooring Failures; and supplements Safety Notice 3 2005 on FPSO (floating production storage and offloading vessel) mooring inspection. The guidance is for marine technical authorities and their contractors engaged in design, installation, inspection, and monitoring of mooring systems. It sets out the actions required of duty holders, and gives further guidance on offshore installation moorings in the appendices. This information sheet takes into account the lessons learned from recent mooring failures during on the United Kingdom Continental Shelf (UKCS) and reflects the emergence of newer, widely accepted codes and standards. It also clarifies the HSE position on interpretation of safety case legislation for the UKCS as this differs from the location approvals given in the Norwegian sector.
This report and the work it describes were funded by the Health and Safety Executive. Its contents, including any opinions and/or conclusions expressed, are those of the author alone and do not necessarily reflect HSE policy.
