Before World War II the British Admiralty conducted a few experiments with helium in collaboration with Siebe Gorman & Co. Ltd and several of the firm's associates, including Sir...
The early 1980s saw a major step forward in saturation diving with the introduction of helium recycling, whereby instead of exhaling the gas mix into the water, it is returned to the bell and thence to the support vessel, where it is scrubbed, sent back down and reused. Recycling systems are...

In the summer of 1957, Associated Divers, at the time the dominant diving company in California, were contracted to provide standby divers for a job in 312'/95M of water. S.V. "Sammy"...

The divers were to work out of the Purisima in Aquala dry suits and full-face masks. Some time before, in the abalone fishery, Bev Morgan and Ramsey Parks had bolted a demand regulator onto a free-flow Widolf mask, which allowed them to use a smaller compressor. After a period making his own...

The worst nightmare for a bell diver is the prospect of having to rescue an unconscious partner. Prompted by the spate of accidents in the mid-1970s, diving companies in the North Sea...
In August 1965, in a cramped chamber at the Ocean Systems research laboratory in Tonawanda, New York, Bob Christensen and Art Noble spent 48 hours at 650ft/198M - a longer and deeper dive than anyone had done before.

Experience with the RCV-125 soon led to a fully-fledged commercial version, the RCV-225, which Martech also ordered. The second American customer for the vehicle was Taylor Diving, a company that became a major operator of ROVs.
The RCV-225 was a great success. As John Lawrence of the former...
