BlueSoul puts the hidden hardware of cleaner shipping in focus at Gastech

The transition to lower-carbon shipping is often discussed in terms of fuels. BlueSoul and Torgy LNG are working on the less visible engineering problem: how those fuels are stored, contained and delivered safely aboard ships.

On the Gastech floor in Bangkok, the BlueSoul name points to a part of the energy transition that rarely gets the headline treatment. A ship can only switch fuels if the machinery around the fuel works — tanks, containment barriers, pumps, pipework, controls and fuel-gas supply systems all have to function as one system.

Shanghai BlueSoul Environmental Technology was established in 2015 with a focus on marine clean-energy equipment. Its product portfolio spans LNG fuel-gas supply systems, LNG cargo-containment technology, exhaust-gas cleaning and cryogenic materials. In 2019, the company acquired Norway's Torgy LNG, adding marine LNG engineering experience that BlueSoul says reaches back to 2008.

The tank is part of the energy story

Torgy LNG's engineering is centred on the systems that sit between a cryogenic fuel and the engine that consumes it. Its fuel-gas supply systems handle LNG storage, regasification and delivery, while its containment work includes IMO Type A and Type B tank designs.

That distinction matters because LNG is stored at cryogenic temperature and ship designers are constantly balancing safety, usable volume, weight and the geometry of the vessel. BlueSoul says its A- and B-type approaches can improve volumetric utilisation by more than 30% compared with conventional C-type tanks in relevant applications. Its Type B design uses aluminium alloy and anti-sloshing structures and is intended for applications ranging from LNG carriers and bunkering vessels to floating storage and LNG-fuelled ships.

From LNG to the next fuel

The more interesting signal from the company is that it is not treating LNG as the end point. Torgy LNG says it has developed ammonia-ready fuel and containment systems, reflecting a wider challenge for shipowners: vessels ordered today may operate through several stages of the maritime fuel transition.

That makes adaptability an engineering and investment issue. Ammonia has different toxicity, storage and handling requirements from LNG, so being “ready” is not simply a change of fuel label. It affects tanks, piping, enclosures, pumps and the fuel-supply architecture.

A link visible elsewhere on the Gastech floor

BlueSoul's technology also connects directly with Northern Marine Group. Tritec Marine, part of Northern Marine, has worked with BlueSoul on a 20,000-cubic-metre LNG bunkering vessel concept. The partners received Approval in Principle from ABS for the “Safe Bunker” design, which uses BlueSoul's aluminium Type B containment technology. The companies had previously collaborated on an exhaust-gas cleaning retrofit project.

The connection illustrates why exhibitions such as Gastech matter beyond individual stands. The marine energy transition is a supply-chain problem: naval architects, ship managers, classification societies, equipment manufacturers and fuel-system specialists have to make the pieces work together before alternative fuels can move at commercial scale.

BlueSoul's proposition is therefore less about one piece of equipment than the infrastructure inside the vessel. As shipping moves through LNG and towards fuels such as ammonia, that hidden layer of cryogenic engineering may determine how quickly new fuels can move from demonstration projects into working fleets.
