OTL has been subcontracted to an engineering company to perform a modular LNG tank design particularly for the transportation conditions. Almost all the existing LNG tanks were constructed at the sites. Concept of LNG tank will allow the fabrication of the LNG tanks at a suitable yard and the tanks will then be transported and installed at site of use. To make this possible, LNG tanks will have to be designed for transoceanic tow, imposing many new challenge to the structural design of the tanks. OTL will help to resolve these technical challenges.
