Scenario: A small, independent oil company has discovered oil/gas in a remote part of the North Sea and early indications show that this would develop into a small to medium size field. The anticipated high price of energy coming from the field appeared to make it reasonably profitable venture over the life of the project. In developing the piping for the extraction and transportation of the oil/gas, the chief engineer and the design team carefully considered the optimum materials of construction for the transportation in the salt water environment. Titanium was strongly considered as a candidate material given the harsh environment and remoteness of the location. Concern was expressed about possible galvanic corrosion resulting from dissimilar metals/alloys/composites found in pumps, clamps, sleeve bolts, flare stacks, nozzles and other pieces of equipment in the salt water which would come in contact with a titanium piping system. Other considerations expressed by the design team were crevice corrosion and microbiologically influenced corrosion. The Chief Engineer turned to Knovel for background information and an overview of the issue.
