Venting arrangements for cargo oil tanks on floating installations

摘要

The UK's Health and Safety Executive has issued a safety notice that highlights the need to ensure suitable and sufficient assessment of the adequacy of venting arrangements for cargo oil tanks on FPSO (floating production, storage and offloading) and FSU (floating storage unit) installations.rnThe notice follows a fire that has recently occurred as the result of the ignition of flammable vapours from an FPSO cargo tank vent. The incident occurred during calm low wind speed (0-2 knots) stable type weather conditions, which were considered to be a contributing factor to the event.
