Our work with LNG storage facilities

We have specific experience in the design and fabrication of liquified natural gas (LNG) storage facilities. Indeed, we played a leading role in the development of LNG process installations at the UK’s first major storage terminals at South Hook, Dragon and Isle of Grain.

Our expertise in large scale LNG terminal projects includes:

• fabrication of stainless steel pipework, storage tank components and major mechanical engineering components
• specialised welding to cope with operating temperatures down to minus 196^o C
• specialised purging techniques over long distances
• clean build procedures to limit residues
• handling of high pressure pumps, submerge construction vaporisers and boil off gas compressors
• installation of loading arms and jetties

Our experience in the sector includes:

South Hook LNG Terminal

Ledwood were awarded the complete mechanical packages within the Process Area due to their success in the jetty works. The jetty works included fabrication, installation and testing  the one mile jetty from land to the operational LNG terminal, as well as the balance of plant (inter-connectivity of pipework between storage tanks). We also undertook the installation of the equipment for the send out pumps and re-condensers.

Dragon LNG Terminal

Ledwood designed, engineered and constructed the highest specification jetty to meet safety, environmental compliance, reliability and quality whilst using commercially proven technology. We fabricated and installed all pipework from the storage tanks to the jetty.

Isle of Grain upgrade project

Ledwood fabricated the aluminium suspended decks for the storage tank roofs. Constructed from the highest quality 60mm aluminium, we shaped, cut and welded each critically designed section to specifically fit into place.
