LNG solutions
Safe, reliable and efficient. Our LNG transfer systems are innovative and easy to use. We are the leading manufacturer of LNG solutions and LNG bunkering systems. Always cutting edge technology, always innovative solutions.
MannTek is the leading manufacturer of easy-to-use, reliable LNG transfer systems and LNG bunkering systems in the world. We produce more than 2500 different couplings and supply over 80 000 couplings per year. All components are manufactured, assembled and 100 % tested in our factory in Mariestad, Sweden and every LNG transfer system are tested cryogenically. Since 2013 we have produced 42 complete LNG Hose transfer systems that are in use. That means 35 000 LNG transfers of 3 million m³ LNG. We have a 100% safety record which includes SIL2 for our LNG solutions.
Advantages LNG
Nitrogen has a lower boiling point – which means no additional heating or circulation system is required when using LNG. We don’t use hydraulics and therefore no hydraulic leaks during the LNG bunkering procedure. We monitor pressure right to point of activation. The LNG system is lightweight and compact and both the PERC and DCC can easily be lifted to the receiving LNG vessel. The PERC has a dual functionality – it is active on ESD2 and passive on ‘blackout’. The hose gives flexibility and responsibility after ESD2. Both Capex and Opex is significantly reduced due to the LNG transferring system.
New ISO standard
We’ve done the job. And once again, MannTek is first. After 1.5 years of constant work and 70 000 connections and disconnections, we have finalised all the tests for ISO 21593, the international standard that regulates the technical requirements of all LNG couplings. This means that our DCC couplings are safe for use in all possible conditions and under any circumstances. Time saving, easy to handle, reliable – and compatible with all other manufacturers that fulfill the ISO 21593.

Ship to ship
(STS) indicates the transfer of LNG from one ship to another.

Ship to shore
LNG is transferred from a ship to an onshore storage terminal/depot.

Truck to ship
Generally an application where ships and ferries are fueled from tank trucks.

Terminal operations
Cover both loading and unloading of rail cars or LNG Tank Trucks.
