RR473 - Review of issues associated with the stability of semi-submersibles

This review study was undertaken as part of a wider exercise to assess the need for HSE Guidance within the UK Safety Case regime. The study included a comparison between stability standards specified by key regulatory authorities and classification societies for intact and damaged semi-submersible units, a review of relevant published literature and of HSE/ Department of Energy reports, a review of past incidents involving loss of stability of semi-submersibles, and a review of issues associated with alternative uses of semisubmersible units.

A key recommendation coming out of this study is that the HSE should investigate further the practicality of reconciling traditional prescriptive stability standards with a risk-based Safety Case approach.
