France’s technological containment specialist Gaztransport & Technigaz (GTT) has received approval in principle (AiP) from the American Bureau of Shipping (ABS), a classification society, for ammonia (NH3)-ready notation of its Mark III containment system on vessels fueled by liquefied natural gas (LNG).
The approval allows future conversion of LNG tanks equipped with GTT’s Mark III technology for NH3 use aboard LNG-powered vessels, making them more versatile and long-lasting as they will be given a new lease on life following conversion. The containment specialist describes its Mark III technology as a cryogenic liner used to contain LNG at low temperatures during shipping, onshore, and offshore storage, at atmospheric pressure.
