What the Byford Dolphin Actually Is
The Byford Dolphin was an offshore oil and gas platform in the North Sea, operated by Phillips Petroleum. It produced oil and natural gas from fields in the UK sector throughout the 1980s and 1990s before being decommissioned. That is the entire thing. There is no software called Byford Dolphin Platform. There is no download link. There is no tutorial. It was a steel structure sitting in the sea, and it stopped being one several years ago. The platform is most frequently searched for because of a well-documented incident that occurred on November 6, 1983. During routine decompression of a caisson to replace a drill bit, the blowout preventer stack blew out due to high pressure. Two workers, Steve Wood and Trevor Clayton, were exposed to explosive decompression. It is one of the most studied cases in occupational safety and hyperbaric medicine. The event reshaped how diving and surface-supplied work protocols are handled in the North Sea industry, particularly around pressure management procedures and lock-out tag-out discipline. I have never worked on that platform. It was decommissioned in the late 1990s. I have read incident reports, HSE documentation, and papers on the medical aspects of the event. What I can tell you is that if you are looking for anything downloadable or procedural about "Byford Dolphin Platform," you are going to come up empty. There is no tool, no software, no guide with that name.
What people actually seem to want when they search this
People who type "Byford Dolphin Platform" into a search engine are usually looking for one of three things. First, they want information about the 1983 incident itself, the safety failures, or the legal aftermath. Second, they confuse it with something else entirely, possibly mixing it up with a software product or a different platform name that sounds similar. Third, they are researching decompression sickness protocols for diving work and found references to Byford Dolphin in technical literature. If you are in the first category, the correct sources are the Health and Safety Executive reports, thefatalaccident inquiry documents, and peer-reviewed papers in journals like Occupational and Environmental Medicine. If you are in the second category, check the exact name you are looking for against something like North Sea offshore platform databases or industry directories. If you are in the third category, the Byford Dolphin case is relevant to recompression chamber procedures and emergency response planning, but it is a historical reference point rather than a working protocol you can implement today. The platform sat at coordinates roughly 57°54'N, 1°35'E in the Viking Graben. It was a six-legged, concrete-based structure. Production began in 1980. It was stripped down and removed by 1999. That is the factual timeline. Anything beyond that is either historical documentation or speculation, and I would advise treating the latter with appropriate caution.
If you are working in offshore safety, I would recommend looking at the current IMCA guidance and HSE's updated technical memorandum series instead of relying on incident-specific documents from the 1980s. The regulatory landscape has moved significantly since then. But that is general advice for anyone in the field, not something specific to the Dolphin itself.
