Cost effective and robust

LNG carriers are among the most sophisticated and expensive merchant ships and the construction has traditionally been limited to a few shipyards. With the current market conditions, and especially with regards to the development of small and mid-scale solutions for the emerging markets, cost-effective solutions are needed to make the projects feasible.

The LNT A-BOX® will enable a wide range of smaller shipyards to build affordable LNG carriers and other floating units. This will open the market, increase competition and enable cost-efficient distribution of LNG. Access to cleaner or reasonable energy such as LNG is vital for economic and sustainable growth in many regions.

There are just a few shipyards today building LNG carriers, but even fewer technology providers for containment systems. The containment systems in the market have essentially been the same for the last few decades and very few major innovations have reached the marked since the commencement of sea-born transportation of LNG. The extremely low temperature and the hazardous properties of LNG vapor make safety a vital concern for any stakeholder involved in the LNG value chain. Hence, safety must always be on top of the agenda and taken care of for any new inventions and solutions. The LNT A-BOX® has been developed according to the revised IMO IGC Code and a criterium throughout the development process has been safety levels equivalent or better than any other systems in the market. Thus, the LNT A-BOX® has been designed as a robust and simple system.

Enabling more shipyards

A simple design and construction of the containment system have been emphasized to enable many smaller shipyards to build LNG tankers. The LNT A-BOX® is based in IMO independent tank type A as the primary barrier. Such Type A tanks are the simplest design and construction among the tank types in the IMO IGC Code and based on classical ship structural principles. Furthermore, the self-supporting tanks can be constructed independently, even outside the yard if this is more effective, and installed on board after the hull erection. This enables more activities to go in parallel and allows specialized and effective workshops build the tanks in their own premises.

In the LNT A-BOX® the insulation system is moved from the tank shell to the inner hull of the ship. The independent type A cargo tanks are fixed to a support system independently of the insulation and thus the insulation with secondary barrier is not exposed to static or dynamic loads from the cargo. This feature enables the design and construction of a simple and efficient insulation and secondary barrier system. Easy and efficient handling and installation of the system has been emphasized during the design of the insulation with secondary barrier system.

Shipyards that will build LNG carriers with the LNT A-BOX® containment system will receive all necessary technical support from our engineers. We will provide design and engineering as well as documentation and training for the construction of tanks, supports and the thermal insulation with the secondary barrier.

By enabling more shipyards to build LNG tankers, competition will also be healthier in the industry. This will further reduce the cost for shipbuilders. Instead of being "locked" to a limited number of builders, a ship owner can now approach yards on a much wider basis.
