Gas analysers for oil industry diving
gas checks
Dominion Gas now serves the North Sea oil industry with cylinder gases from production units in Stavanger and Bergen in Norway and from Singapore serves South Asia
Supplying cylinder gases for diving, welding, industrial, laboratory, test and calibration gases demands standards setting, quality and rigorous procedures: since its foundation, Dominion has used gas analysis equipment from Systech Instruments to underpin its quality assurance programme "We have used Systech gas analysers since day one because they give us the reliability we must have to protect our reputation," says Dominion Gas Quality Manager, Graham McIntosh, "for supplying a high quality product

A large part of the Dominion Gas business is the supply of specialised diving gases where purity is a matter of life and death.
Although a few years ago it was forecast that ROVs (Remotely Operated Vehicles) would dramatically reduce the need for human divers to maintain undersea installations, there are still many activities that only a human diver can undertake.

This has increased the demand for diving gases, especially for special mixtures that enable divers to work for longer periods at greater depths.
The most widely used are 'nitrox' a mixture of nitrogen and oxygen, 'heliox', a helium and oxygen mix, and 'trimix', helium, nitrogen and oxygen.
The proportions of the gases in the mix, depends on the dive depth, must be precise: purity is paramount.
At each of its four production units, Dominium Gas has a rig built using four Systech gas analysis instruments to continuously monitor both gas content and purity.
Systech 830 and ZR894 zirconium oxygen analysers to monitor O2 content, a Model 542 programmable gas analyser to monitor the proportion of gases in a mix and a Model 300 to detect any trace of carbon dioxide in the mix.
Graham McIntosh has developed a standard rig that is now used in all the production units so that the layout is always familiar even to technicians who might work at more than one site.
"Whether we are producing gases for diving, welding or calibration use," says Graham McIntosh, "quality is equally important.
Dominion Gas has an outstanding reputation for reliability and the quality of our products - with diving gases, a man's life depends on our rigorous quality assurance techniques.
We constantly assess gas analysis equipment from other manufacturers but we have yet to find one that matches the Systech equipment for built-in experience, quality and reliability".
