Typical Reference List
List of References in LNG (CNASEC).pdf
With over 30 years of laborious development, CNASEC has become a national engineering company taking technology as the core while developing engineering design, consultation and EPC projects simultaneously. We adheres to the policy of creating value for customers and take quality as priority. Keep on providing service to the customers at domestic and abroad as always. We will also make unremitting efforts to become an international engineering company with obvious characteristics and strong design, procurement, project management and general contract ability.
To date, CNASEC has established over 30 projects related to LNG and Ethylene etc., and been equipped with the ability of designing and developing 100,000m3-level full containment tanks. In addition, the company has successfully generalized a set of standardized systems of storage tank engineering, realizing the short-term goals of the construction period and successfully shaping the national brand image of large-scale cryogenic liquefied storage and transportation projects!
