The following is from the wiki. Note the word 'claim'. I don't think that there is any evidence that the Peter Bruce who was responsible for the yachting Bruce anchor ever supplied anchors to the oil industry. This comes from:-
http://en.wikipedia.org/wiki/Anchor#Bruce.2FClaw
Bruce/Claw This claw shaped anchor was designed by Peter Bruce from the Isle of Man in the 1970s [2]. Bruce claims the invention to be based on a design used for anchoring floating oil derricks in the North Sea. The Bruce and its copies, known generically as "claws", have become a popular option for smaller boaters. It was intended to address some of the problems of the only general-purpose option then available, the plough. Claw-types set quickly in most seabeds and although not an articulated design, they have the reputation of not breaking out with tide or wind changes, instead slowly turning in the bottom to align with the force.
Genuine Bruce anchorClaw types have difficulty penetrating weedy bottoms and grass. They offer a fairly low holding power to weight ratio and generally have to be over-sized to compete with other types. On the other hand they perform relatively well with low rode scopes and set fairly reliably. They cannot be used with hawse pipes.
Bruce Anchor Group no longer produce the genuine anchor although other companies make reproductions

This is the one they use for oil rigs:

Obvious similarities I'd say
