Subsea engineering benefits from review

Deepstar Subsea are a company in the North East of England involved in the design and manufacture of engineered products for subsea applications.

Like all companies, Deepstar Subsea wanted to improve customer service, and one way of achieving this was to improve their bidding system for duplex pipework and other materials in common use in the oil and gas industry.

Specifically, it would be an advantage to be more aware of possible problem areas or technical difficulties particularly in the field of joining dissimilar materials.

Harry Forrest from Deepstar contacted TWI having heard about their Joining Forces programme. "I had a number of high alloy steels and nickel based alloys I wanted to review for the business, and required that the information be presented in a succinct and easy to use format. TWI has the experience and expertise to coordinate such a minefield of information".

The programme was able to offer the company a Review of its materials selection requirements, the results of which were presented in a comprehensive table summarising material data and welding considerations for alloys being specified for new contracts.

The information covered such topics as typical mechanical properties, welding processes, the need for pre-heat and potential problems in manufacturing applications.

Deepstar Subsea were very pleased with the outcome of the Review and are now using the information on an everyday basis.

TWI's help was available to Deepstar under the Joining Forces North East technology transfer programme.
