Bureau Veritas (BV) has awarded an approval in principle (AIP) to Gas and Heat (GH), a company specialising in the design, construction and integration of liquefied gas handling systems both for marine and onshore installations.
GH supported by the BV team demonstrated that IMO Type C cargo/fuel tanks made of austenitic steel with a special grade can transport both LNG and ammonia for sea-going and inland navigation.
GH has used austenitic steel with a special grade for LNG containment since its approval by Bureau Veritas in June 2022, as an “alternative material” with respect to IGC/IGF Code.
The compatibility of this material with ammonia has been verified by a specific stress corrosion cracking test performed by GH and then approved by Bureau Veritas.
Paillette Palaiologou, vice president south east Europe, Black Sea and Adriatic zone at Bureau Veritas marine & offshore, said: “While the shipping industry is facing many uncertainties, it is the role of class to support the industry in this period of change.
“I am proud of the work accomplished by both teams and the results are extremely positive for the industry. Providing different options will be key for industry stakeholders as they make decision. We look forward to collaborating with GH on new projects.”
Mauro Evangelisti, president of Gas and Heat, said: "Innovation has always been and will remain our main focus. This study is part of the innovation journey the industry needs for a smart and sustainable transition to a greener future. We hope the use of this material will provide more cost-effective and safer components to the industry."
