The contract follows the signing of an agreement in November 2019 between GTT and the Chinese major state-owned company Beijing Enterprises Group (BEG).

HQC chairwoman Wang Xinge said: “With the support of GTT, HQC had deeply prepared the company on building the first Membrane Full Containment tank in China.”

BGG board chairwoman Li Yalan said that BGG conducted a comprehensive evaluation of the application of Membrane technology onshore, with national and international experts.

Yalan added: “Besides the high level of safety and the intrinsic technical merits of the Membrane system for onshore application, this technology is more cost effective and requires less material than other available technologies, which leads to a significant reduction of the impact on the environment.

“Going forward, BGG is proud to take the leading role towards more environmental friendly infrastructure together with HQC and GTT for this national emergency project.”

In April 2020, State-owned oil and gas company Qatar Petroleum has signed QAR11bn ($2.99bn) deal with Hudong-Zhonghua Shipbuilding Group to reserve LNG ship construction capacity.
