Cooperating competitors verifying a global standard

On the 22nd of July history was made in the development of LNG bunkering and its future when one of Europe’s gas majors invited quick coupling manufacturers to an interchangeability test.

Three European manufacturers (German, British and Swedish) were invited to take part in the test held at the Gutteling facilities in Rotterdam. The purpose was to verify and prove interchangeability between different manufacturers quick couplings according to the ISO 21593 Standard.

This is a crucial point in LNG bunkering procedures in that it ensures any bunker vessel or bunker station is able to service any LNG powered ship anywhere in the world as long as both parties carry a quick coupling according to Standard.

Unfortunately, only two manufacturers, KLAW and MannTek, took part in the test while the German manufacturer declined the invitation.

The test was a complete success and justifies the effort in establishing an ISO Standard for an LNG ship bunkering interface that guarantees bunkering interchangeability worldwide.

As manufacturers both KLAW and MannTek would like to jointly thank the driving forces behind creating this standard such as the gas majors, shipping operators and not least SGMF for its support.

In our line of business we need to meet the highest Standards regarding Safety and Quality. We work hard to fulfil both internal demands and external as ISO 9001 and PED. When we deliver our LNG Solution Systems their additional demands as for example SIL 2.

We are happy to announce that from 1 June 2019 Richard Butler joined MannTek as Quality Director. Richard holds a degree in Marine Engineering with more than 30 years of experience as Senior Lead Assessor and previously Engineer Surveyor at Lloyds Register in UK, Australia and Sweden.

In the future we can offer more specialized Consultancy services regarding both our products and Systems solutions.

We would like to thank Per Nordsjö for his services at MannTek for 15 years. Per has not only been the Quality director but has also act as an advisor for the Management. Per’s contribution to the development off MannTek cannot be overstated and Per will now retire.

2018 was another successful year for MannTek. The turnover increased with nearly 30 percent vs 2017. MannTeks turnover has increased every year except two from the time the company started. From a start-up company to market leader in Dry Disconnect Couplings in 20 years. Our LNG Solution products have gone from zero to one of the Leading Solutions for small scale bunkering in only a few years. Now we are looking forward to 2019.

MannTek has delivered a complete transfer system to Antony Veder which is going to be part of the modification of the LNG carrier Coral Methane into an LNG bunker vessel. Starting in 2019 to cover the LNG bunkering demands across Europe, the primary operating area is going to be the southern parts of the North Sea as well as the Mediterranean Sea.

The system includes an 8 inch PERC and 6 inch MannTek Dry Cryogenic Couplings. The transfer line also includes the MannTek innovative designed nitrogen activated PERC's monitored and controlled by the high pressure nitrogen system (HPN2). The HPN2 monitors, controls and releases the PERC's by utilising high pressure Nitrogen and controls the pressure right to the face of the valve before and during the LNG transfer. Using an innovative low pressure nitrogen system which is monitored continuously ensures that on ESD2 the valve will separate. This system is also including a programmed PLC that monitors the transfer and has included automatic checks support. The system is SIL2 rated by DNV.

MannTek has delivered a LNG transfer system to Swedegas, who is building a bunkering facility for LNG in Gothenburg. The Transfer system which uses MannTek DCC and CBC-PERC couplings is going to be part of a construction that has been ongoing since winter and is scheduled to open in August 2018. The thought behind this facility is for vessels to be able to bunker LNG at the same time as the unloading and loading of cargo is going on.

Florida East Coast Railway has become the first North American railroad to adopt LNG (liquefied natural gas) for its entire line-haul locomotive fleet.

FECR on Nov. 9 officially rolled out its 24-unit fleet, consisting of 12 pairs of back-to-back GE ES44C4s with a purpose-built Chart Industries fuel tender in between, at Bowden Yard, Jacksonville. FECR, a Class II regional, is also the first railroad to haul LNG as a commodity, under a Federal Railroad Administration waiver.

The FAT for the LNG Transfer System supplied to Coralius included two PERC's that was simultaneously released

The FAT for the LNG Transfer System supplied to Coralius was performed with success and included two PERC's, Dry Cryonic Couplings, ESD 1 & 2, PERC activation and monitoring unit and LNG bunker hoses.

On this project, MannTek worked closely with Sirius Shipping, the Anthony Veder Group and Skangas, the vessel’s charter company, on the installation of the system.

Markus said: “During the project we have made design suggestions that we felt would improve the way the system is fitted to the vessel. We were involved from a very early stage in design as bunking activities on a vessel need to be able to take place at four different locations.”

The Coralius started operations in the Baltic Sea and the North Sea in September.

Coralius makes it's first ship-to-ship bunkering

Yesterday  between 08.00 -14.00 Coralius and Fure West made their first Ship-to-Ship bunkering, using MannTek LNG Transfer System. The operation was successful and took place at open sea between Gothenburg and Denmark.

MannTek has delivered another LNG Transfer System, this time to Wärtsilä and the Tornio Manga LNG Terminal. Wärtsilä is a recognised leader in gas engine technology and has, just like Skangas did at the Pori terminal, chosen MannTek LNG Transfer Systems for bunkering and delivering LNG.

A Factory Acceptance Test (FAT) has been successfully completed. The system consists of Manntek’s DCC (Dry Cryogenic Couplings), CBC (Cryogenic break-away Couplings), LNG bunkering hoses, an ESD (Emergency Shut Down which provides an ESD signal to ship or shore ESD system) and HPN2 (High Pressure Nitrogen System).

MannTek LNG Transfer Systems are lighter, by up to 50%, than any other LNG transfer system available today. This weight-saving is vital to owners and operators of the system as it makes it easier and safer for operators who have to manually lift the connections. MannTek’s CEO Markus Bäckström said: “The lighter design makes for a more maneuverable design which in turn makes the role of the system’s operators easier, and more importantly, safer.”


The Tornio Manga LNG Terminal is scheduled to be operational in the beginning of 2018 and will provide LNG for a new generation of LNG powered ships. It will be the largest imprt terminal for LNG in the entire Nordic region.
