LNG membrane tank system added to Canadian Standard

GTT has confirmed that the new release of the Canadian Standard for LNG Production, Storage and Handling, now includes and recognises the membrane tank system as a possible technology for the land storage of LNG in Canada.

The membrane containment system technology has been integrated into the newly published Canadian Standard CSA Z276 2015 edition.

The request to include the containment system originally initiated from the LNG community, in order to meet the challenges of LNG export projects in remote locations.

Recent LNG export developments in British Columbia and other Canadian provinces sought solutions that met the high standards of the LNG industry, but with advantages in schedule, cost and local work content.

The inclusion of the membrane containment tank language took more than two years, in order to follow the rigorous CSA process, including public review.

The inclusion of the technology has been realised in collaboration with world LNG tank and LNG facility safety experts, from major engineering, procurement and construction (EPC) companies, as well as oil and gas majors.

The language takes into account the latest international tank design standards, such as API 625, API 620 and ACI 376, as well as EN 14620

The new edition of CSA Z276 follows the action of British Columbia Oil & Gas Commission (BCOGC), which officially included membrane tank technology in its recent LNG regulation issued 21 July 2014. With the new edition of the CSA Z276 standard, the membrane tank technology is now addressed not only in British Columbia but for other Canadian provinces.

The English version of CSA's Z276 2015 standard is available for purchase here.
