The presence of a simultaneous combination of several hazards is common during scuba diving, and the effect is generally greater for the diver, especially if the occurrence of an incident due to a hazard triggers other hazards with a cascade of incidents resulting. Many dive discs are the result of a cascade of incidents that overwhelm the diver, who should be able to deal with any reasonably foreseeable incident. [Citation required] Statistics on injuries related to commercial scuba diving are generally collected by national regulatory authorities. In the United Kingdom, the Health and Safety Executive (HSE) is responsible for the inventory of approximately 5,000 commercial divers, and in Norway, the appropriate authority is the Petroleum Safety Authority Norway (PSA), which has been managing DSYS es ese data since 1985 and collects statistics on 50,000 hours of diving per year. [Citation required] Some diving support vessels have an opening through the bottom of the hull, called „Moonpool“, to facilitate the use of divers. This is usually the part of the ship with the slightest vertical movement in a sea route that allows to start and restore the bell or scene easier, safer and more convenient for divers. [Citation required] On July 1, 1978, a number of „temporary rules“ [for diving] were introduced 12 years after the start of scuba diving and 11 years after the first serious accident. The diving industry is dangerous and has had a number of serious accidents over the years, and although work processes and equipment have evolved in response to accident analysis and the balance sheet has improved, diving at sea remains a relatively dangerous occupation. This section lists some of the most notable incidents. It dates back to the early 1980s and regulates the minimum wage, benefits and health insurance for British divers. Molloy added that the agreement would allow the parties to refocus on helping industry achieve Vision 2035, a common goal to give the North Sea a generation of production life and double the international supply chain opportunities to provide $920 billion to the UK economy between 2018 and 2035. Divers can work on offshore lifts (pipes that extend an underwater oil well to a surface facility) and Blowout prevention batteries on all types of production facilities when the depth is in a dive area.

The work can be oriented on the surface or in saturation, depending on the depth and duration. RMT said about a thousand workers in dive teams voted on the agreement negotiated every three years.
