This report presents a review of the Norwegian ‘Risk Assessment of Buoyancy Loss ’ (RABL) project, completed in 1988. RABL was undertaken in the aftermath of the Alexander L. Kielland and Ocean Ranger accidents. RABL’s stated purpose was to investigate causes of loss of buoyancy of semisubmersible drilling platforms, with the overall objective of developing an analytical procedure for consideration of buoyancy loss. This procedure was intended to be analogous to guidelines applied to fixed platforms in Norwegian waters. RABL demonstrated that it is practical to carry out a risk assessment of buoyancy loss for semisubmersibles. The RABL methodology and procedure were considered to be robust and sensitive to differences between concepts, and RABL recommended that the new analysis methodology should be used to assess safety levels for new platform designs, or for existing platforms subject to changes in operational premises. This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy
