The early days of the 'oil goldrush' are long gone, as is the 'experimental' era of Commercial Diving. We know now what is safe and what is not. There is, then, NO excuse, other than Financial expediency, for Divers to continue to die. People say Diving is inherently dangerous. It is not. There is, however, a great deal of RIsk involved. Risk can be identified and managed. Admittedly, some Divers are their own worst enemy, willing to go a little too far for the 'company' or getting into a financial position where they have to accept work which they may feel dubious about, but if the company and senior staff have a strong grip on safety, and a willingness to do the work the right way, then even these Divers would not be put in this position in the first place. There are also far too many clients (especially in the inshore sector) who do not know the regulations, and are happy for Diving Contractors to work unsafely with the defence that they are the experts, and should know what they're doing. Not good enough.
If these Divers had been in another profession, say Crab Fishermen for example(!), it would be front page news. Why do so few people care?
