"In view of the international sanctions currently in force, which are increasingly affecting LNG liquefaction projects in Russia, the continuation and proper performance of these contracts are subject to risks that the Group is unable to assess at this time," GTT said in its quarterly earnings statement.

The firm, which designs tanks for maritime transportation and storage of liquefied natural gas (LNG) carriers, added that international sanctions which affect exports to Russia of products or equipment used in the group's projects, may result in their deferral or in cancellations.
