SGS Completes LNG Design Verification

In just four months, SGS Industrial Services has completed the design verification of three cryogenic liquefied natural gas (LNG) tanks in accordance with Canadian code CSA Z276-01. Canaport LNG in Saint John, is a consortium between Irwing Oil, New Brunswick and Repsol, Spain, constructing the first LNG receiving and regasification terminal in Canada. After four years under construction, the Canaport LNG terminal should begin operations in the second quarter of 2009 and supply natural gas to the Canadian and American markets.

With its three large LNG cryogenic tanks, the first Canadian LNG terminal has a capacity of one billion cubic feet or 28 million cubic meters of natural gas per day and represents a capital investment of CAD750m (GBP413m). A project of this magnitude requires a strong international team in order for it to be completed in such a tight timescale. SGS Canada contributed to this success with its experienced team of engineers and professionals.

In four months, SGS succeeded in reviewing all tank design plans and verified them in accordance with CSA Z276-01, a code set up by the Canadian Standard Association concerning the production, storage and handling of liquid natural gas.

This CSA standard sets a range of 426 requirements and such a design verification project can generate around 40,000 pages of documents and drawings. Within three months, all the 426 requirements were matched with the concepts and drawings, calculations were verified as correct and the LNG tank design was confirmed as complying with the Canadian CSA standard. The final report was issued to the satisfaction of the customer, on time and on budget.

With the completely independent certification from SGS, Canaport LNG can be sure that the facility will operate as intended, using the latest technology, to the highest safety levels, and meeting all the relevant environmental standards and regulations. SGS Industrial Services provides not only design verification of LNG tanks, but also offers support services related to mechanical, piping, and electrical systems design, such as mechanical and process design review, fire and safety systems analysis, and instrumentation and automation analysis and review.
