“Gas and Heat and Bureau Veritas make cargo/fuel tank compatible with both LNG and Ammonia”

Gas and Heat and Bureau Veritas make cargo/fuel tank compatible with both LNG and Ammonia

 

Paris La Défense, September 12, 2022 – Bureau Veritas (BV), a world leader in testing, inspection and certification, has awarded an Approval in Principle (AIP)toGas and Heat (GH), a company specializing in the design, construction and integration of Liquefied GasHandling Systems both for Marine and Onshore installations,for their flexible solution for the transport of LNG and ammonia.

 

Through a thorough study, GH supported by the BV team demonstrated that IMO Type C cargo/fuel tanksmade ofaustenitic steel with a special grade can transport bothLNG andammonia forsea-going and inland navigation.

 

While LNG is expected to be widely used this decade, alternative fuels are under scrutiny to ensuretheir safe and sustainable use in the future. At the same time, shipowners are becoming more and morefocused on multi-fuel supply systems able to handle two or more different fuels. As part of their ambitions to develop innovative solutions to help the industryanticipate the next wave of alternative fuels, GH embarked on a study to identify possible options and develop solutions.

 

GH has used austenitic steel with a special grade for LNG containment since the Approval in Principle by Bureau Veritas in September 2022, as an “alternative material” with respect to IGC/IGF Code. The compatibility of this material with ammonia has been proved bya specific Stress Corrosion Cracking test issued by GH in August 2022 and then validated by Bureau Veritas.

 

For this innovative material in the shipping world, twelvespecimens were prepared for the tests inaccordance with ISO 16540.ISO 16540 provides guidelines to evaluate the corrosion of metals and alloys by determining their resistance to stress corrosion cracking using the Four-Point Bend method. This methodology includes procedures for metals that have no distinct yield point in their stress-strain behavior as well as metals with a distinct yield point.

 

Throughout the test, the specimens were loaded as Four-Point-Bend (FPB) to the Specified Minimum Yield Strength of the base material.Tests werethen performed in three different conditions: at ambient temperature, -20C, and -33C,in an environment of pure ammonia. After the completion of all tests, each specimen was visually examined at x10 magnification by stereoscopic microscope and subjected to fluorescent liquid penetrant examination to detect any visible surface crack.An additional tomographic scan was performed to ascertain that no inner crack was detected.The outcomes successfully demonstrated that cargo/fuel tanks made of austenitic steel can carry both LNG and ammonia, for seagoing and inland navigation.

 

BV was involved from the very earliest stages, validating the stress test methodology and reviewing each phase of the test. We confirmed that the applied methodology to design Type C tankcomplies with the International Gas Carrier (IGC) and International Code of Safety for Ship Using Gases or Other Low-flashpoint Fuels (IGF) Code which applies to marine vessels carrying liquefied gas in bulk, as well as applicable BV’s classification rules for seagoing and inland navigation.

 

Paillette Palaiologou, Vice President South East Europe, Black Sea & 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 SpA, 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.”

 

GH has already secured one contract which includes the supply of cargo tanks forinland navigation of LNG/ammonia and one for a seagoing LNG/ammonia fuel supply system.
