The outstanding performance of titanium
and its alloys in sea water, brackish and polluted waters, and petroleum
refinery environments has been fully exploited in recent years by the offshore
oil and gas industry.
Today, principally in the Norwegian sector of the North Sea , the number and variety of applications of
titanium and titanium alloys offshore is increasing at an exponential rate.
From no more than a few hundreds of
kilos used in chlorination systems and heat exchangers twenty years ago, total
consumption of titanium now exceeds several thousand tonnes, with each new
project likely to see greater use of titanium than its predecessor, Persistent corrosion problems with steels, particularly crevice corrosion, have
been eliminated by use of titanium for low pressure ballast, fire and service
water pipework. Typical consumption for topside pipework now ranges from 50 to
150 tonnes per platform.
