IMO A – Tank

Torgy’s LNG A-Tank is based on conventional A-Tank, commonly used for LPG, but there is a need for an entirely secondary barrier to comply with LNG use requirements. The secondary barrier developed by Torgy LNG is a metallic barrier, by use of thin plates in Stainless Steel, organized to handle the cryogenic environment and the challenging effects of cooldown during operation. 

Torgy-LNG has patented the design and layout for the innovative pattern, named “Fishbone pattern, ” which releases the stress in membrane plates during cooldown. 

The system is based on previous approvals for GASA completed in 2013 and 2017, but now with material and build-up to meet the customer’s reliability and cost.

IMO A-Tank for LNG-use gives some benefits compared to other known tank types in the market:

  • Space efficiency; shaped to fit the vessel.
  • Reliability 1; by use of a known and field-proven A-Tank as the main barrier.
  • Reliability 2; by use of a metallic secondary barrier.
  • Production time; A-Tank will be produced in parallel with the vessel.
  • Cost; depending on size, vessel type, machinery, customer requirements, etc.


Torgy-LNG develops an innovative compact SMR for the production of Hydrogen “on-site.” Our solution is a cost-effective producer of Hydrogen and possible to be part of the train for continuous production of electricity. That means handling and the amount of Hydrogen to a minimum at all time during power production. 

Our solution will give the advantages of Hydrogen with minimized handling, environmental disadvantages and increase safety. 

Hydrogen offers boundless opportunities and environmental benefits. The low carbon element is the most abundant substance in the universe; with emission as pure water and electricity as the outcome, it is obvious to see Hydrogen as a solution for green power.  

Transport and handling are also challenging due to extremely low temperatures, -270 C in atmospheric pressure or extreme high pressure (700 bar) in ambient temperature. 

Safety is highly prioritized for explosion-proof handling. 


Ammonia, Empiric formula NH3, is today one of the major priority areas for the green shift. In the case of the correct production methodology, it can be considered “zero emissions”. Ammonia is suitable as fuel in the transport sector, where there is a relatively high consumption over long distances. The energy density is relatively low compared to other fuels and thus requires greater tank capacity. 

However, liquid Ammonia storage has challenges be it far less than other comparable fuels such as Hydrogen or LNG. Ammonia’s boiling point is approximately -33°C; this is manageable with today’s cooling systems and by use of insulated tanks. Ammonia is a toxic gas and highly corrosive; it, therefore, requires an additional barrier to the environment. 

The production of Ammonia is a well-known process, most known from the fertilizer industry that was industrialized by Hydro (Birkeland/Eyde). Ammonia occurs in many natural processes, but development is required for efficient and green production. 

Ammonia is one solution in relation to the requirement for zero emissions, dependent on how it is produced. The technology for Ammonia’s production is the key to becoming a green solution, and it is currently researched vigorously worldwide to achieve this. 

There are currently numerous solutions for how Ammonia is used. As fuel for conventional internal combustion engines, either in gaseous form or injected in liquid form, or through a fuel cell to produce electricity. In due time in the future, it will become apparent which technology is favorable for use, based on energy, economy, and emissions. 

Torgy-LNG is working with optimized Fuel Gas Supply Systems (FGSS) called Ammonia ready. That means we also consider Ammonia in calculations for our FGSS’s. Since Ammonia engines are still slightly premature, we will base the readiness to include all costly details that would not be affected by what kind of technology to be used for the engine feed (gas or liquid). To be prepared for Ammonia, we calculate and build a Tank to be compatible with Ammonia and all piping to be double-walled to meet the criteria for Ammonia. The FGSS will be possible to upgrade for Ammonia, depending on what type of feed is wanted for the Engine. 

Torgy-LNG also challenges conventional production technology with innovative solutions to get the closest possible target of zero emissions for the entire chain.
