GTT announces new developments in its membrane technologies and related services
- Introduction of Mark V, an updated version of the Mark III system
- Launching of NO 96 Max, an upgrade of the NO96 design
- Opening of a training center in France in June 2014
At its 4th Innovation & Technology seminar, held on March 28th at the end of Gastech, the gas technology conference and exhibition held in Seoul, Korea, GTT presented the new Mark V & NO 96 Max systems and a new training centre, expanding the group’s range of services for the LNG transportation and storage sector.
The Mark V, a variant of the well-known Mark III system, introduced in 2013 at the LNG 17 conference for LNG bunker tank projects with a new metallic secondary barrier, is now available for use in LNG carriers to be constructed in 2016 and delivered in 2018.
In addition, the new NO 96 Max system, an upgrade of the well-known NO96 GW design, incorporating an innovative pillar-type insulation box construction, will also be available as of 2016.
Both systems incorporate solutions for a low daily cargo evaporation, known as daily Boil-Off Rate, at a guaranteed 0.09% of cargo volume per day combined with an optimization of the construction process and cost.
These systems are designed to equip the next generation of LNG carriers featuring more efficient propulsion systems (less requirements for Boil-Off Gas for propulsion) and optimized hull forms.
GTT also announced that the current and future membrane systems meet the requirements for the carriage of other liquid gases such as ethane, ethylene, butane, etc, further extending their flexibility.
To enhance its service offer, already including service agreements for ship-owners and a 24 hour, 7/7 hotline, GTT has opened a new Training Centre in its headquarters near Paris, France.
Staffed by a team of specialist instructors with extensive training experience within the maritime sector, and drawing on available expertise within GTT, the Centre will provide training courses based on practical exercises in relation to the LNG industry, not only focused on GTT’s technologies. Equipped with state of the art equipment, and a newly developed LNG operation simulator, the centre will offer a portfolio of courses covering the whole range of LNG handling operations in the maritime and shore based sectors.
The first courses will start at the end of June, focusing on the training required for ship officers on LNG Carriers, and the practical aspects to be considered when using LNG as a fuel.

|GTT North America receives AIP for Membrane LNG Bunker Barge|
Houston-based GTT North America (GTTNA), US subsidiary of French engineering and technology company GTT (Gaztransport & Technigaz SA), has received approval in principle from ABS for the design of a 2,200 cubic meter liquefied natural gas (LNG) bunker barge. The distinctive design incorporates GTT’s proven membrane Cargo Containment System (CCS), which is utilized in 70% of the global LNG carrier fleet and nearly 90% of LNG carrier projects on order.
Leveraging over five decades of LNG storage and maritime transportation experience, GTT developed the membrane LNG bunker barge to demonstrate the efficient storage of LNG and safe, reliable management of Boil-Off Gas (BOG) in an unmanned push barge application. The barge was designed for use in bunkering operations including ship-to-ship LNG transfers or LNG bulk transport in US inland waterways, harbors, and intra-coastal service. The barge could operate as a mobile refueling resource or be moored temporarily to serve as a refueling station.
“An important step in the wide-range adoption of LNG as a marine fuel is the development of bunkering infrastructure that can adequately meet the various operational needs of vessels,” said ABS Director of US Gas Solutions, Roy Bleiberg. “The use of the LNG bunker barge will be a critical part of infrastructure development and this design, which leverages proven GTT technology, is certainly a concept that LNG stakeholders should consider.”
The CCS selected for the barge was GTT’s proprietary Mark III Flex system, an enhancement of the Mark III system that allows for improved thermal and structural performance of the CCS. The Mark III membrane CCS consists of a cryogenic liner directly supported by the vessel’s inner hull, which allows for maximum volumetric utilization of the available cargo space. This liner is composed of a primary metallic membrane fastened atop a prefabricated insulation panel that includes a complete secondary membrane.
The GTT membrane LNG bunker barge will be capable of loading 2156 m3 (@98%) or 570,000 US gallons within 4.5 hours and towed at maximum speed of 8 knots in an efficient footprint: 64.2 m (212 ft) overall length, 14.8 m (48.5 ft) breadth, 7.2 m (15.7 ft) depth, and 2.6 m (8.5 ft) fully loaded design draft. The dimensions and gross tonnage of approximately 1440 GT afford the GTT membrane LNG bunker barge greater maneuverability and access throughout inland and intra-coastal waterways.
A distinguishing feature of the GTT membrane LNG bunker barge is the management of natural BOG through small-scale reliquefaction units. The StirLNG-4 cryo-cooler unit from the Netherlands-based Stirling Cryogenics was the basis of the boil off management system design.
“This barge design, now approved in principle by ABS, provides a robust solution for boil off gas management, an essential requirement for any atmospheric LNG storage system. The design is a major step forward in bringing the coldest cargo with the highest stored energy value to the US LNG fuel market in a safe manner.” said Allyn Risley, Chairman, GTT North America.
Alameda, CA-based Herbert Engineering Corp. (HEC) was commissioned to develop the hull and preliminary machinery design scope and Houston-based CH-IV International to develop the cargo handling system (CHS) design scope.
ABS Consulting also assisted in the development of the GTT membrane LNG bunker barge project.

|Enhanced Safety for LNG Vessels : StormGeo’s Seaware product adds GTT’s tank sloshing prediction and alerting system|
January, 2014, Saint-Rémy-lès-Chevreuse, France and Bergen, Norway – StormGeo, the global weather services company, has partnered with French company GTT to add enhanced Liquid Natural Gas (LNG) membrane tank sloshing prediction and monitoring to their current Seaware EnRoute Live (ERL) onboard software product. LNG shippers who use this product will benefit from Seaware seakeeping operational decision support that incorporates components of ship motion, stability, weather, and sea state. This well proven vessel monitoring complements GTT’s industry leading expertise in the design and development of cargo tank systems for LNG carriers.
Sloshing in tanks is one operational factor to be considered for all LNG carrier owners or operators. Due to its stochastic nature, sloshing can generate impacts on the containment system, for which zero risk cannot be attained, even in moderate sea states. Furthermore, sloshing is also identified as a first order factor for the increase in natural boil off of the liquid cargo. Managing the risk of sloshing is then a critical economical concern for all the actors of maritime LNG transport. To avoid an excessive tank sloshing incident at sea, this Seaware on-board system with GTT’s Sloshing Prediction Program takes into account the detailed hull lines of the ship, the actual loading condition, roll damping, wave spectrum, and ship speed/heading. The captain can, prior to departure, simulate and plan a sailing route mitigating potential tank sloshing risks as part of a safe and efficient Seaware calculated optimized route recommendation. As loading condition, weather, and sea state conditions can change during transit, Seaware’s ERL uses its tactical alerting mode to alert the Captain and bridge officers for potential excessive tank sloshing risk with enough time to change course or speed and to provide guidance in choosing the most efficient mitigation action. GTT collaboration with StormGeo can also develop sloshing impacts monitoring systems which can be used at sea to monitor real time sloshing activity in the tanks and check the efficiency of mitigating action. Based on GTT’s expertise on statistical sloshing data analysis and Seaware ERL monitoring/recording capacities, post voyage analysis can also be performed, enabling fleet management constant improvement.
“Seaware EnRoute Live is the most advanced onboard weather and ship routing product suite in the market,” states Kent Zehetner, CEO of StormGeo. “The addition of the sloshing prediction program will add significant value for our LNG clients by improving safety during the voyage. We measure success through the number of risks we enable our clients to avoid.”
Philippe Berterottière, CEO of GTT adds, “Our expertise in LNG shipping technology and StormGeo’s dominance in the weather services market make this partnership a natural fit for GTT. Sloshing prediction modules are the next step in ensuring the safest possible sea crossing for our LNG customers.”
StormGeo is a global weather services provider with operations in Offshore, Renewables, Media, Corporate Enterprise and Shipping industries. As one of the world’s largest commercial weather service providers, it serves a worldwide customer base with advanced solutions through its 24/7 forecasting desks. Seaware EnRoute Live is a StormGeo software product that provides shippers with crucial data relating to their cargo, sea conditions, and weather risks along the voyage.

|GTT receives Best Paper Award from ISOPE conference|
For the second time in three years, ISOPE rewarded Laurent Brosset, Technical Expert in the Liquid Motion Department at GTT, with the Best Paper Award, for his contribution to the article “Elementary Loading Processes (ELP) involved in breaking wave impacts: findings from the Sloshel project”.
The International Society of Offshore and Polar Engineers (ISOPE) gathers every year hundreds of engineers and researchers for a conference composed of several symposia mostly related to marine engineering.
ISOPE is one of the most important technical conferences, along with OMAE, on this domain. What makes it particular is its special symposium dedicated to sloshing.
GTT has participated actively in every conference since the first one including a sloshing symposium, which was held in Osaka in 2009.
Each conference ends with a rewards ceremony, including the best conference paper of the previous year. On July 3rd, this prize was awarded to Wim Lafeber (MARIN), Hannes Bogaert (MARIN) and Laurent Brosset in Anchorage (AK, USA). The paper was selected from a total of 645.
“Elementary Loading Processes (ELP) involved in breaking wave impacts: findings from the Sloshel project” shows that all wave impacts generate loads in time and space domains, which are always made of the 3 same elementary components (Elementary Loading Processes or ELPs). This result is illustrated thanks to experimental data (mostly pressure measurements and synchronized high speed videos recording the shape of the waves during impacts) obtained during wave impact tests in the Delta flume of Deltares (NL), at the time of the Joint industrial Project Sloshel.
The first ELP appears at the first contact point between the free surface and the wall. It is related to the propagation of a pressure wave throughout the liquid. The second ELP basically corresponds to the hydrodynamic load. The third ELP is associated to the gas compression either when the gas escapes during the wave approach or when it is entrapped in pockets in between the liquid and the wall.
This decomposition of the loads due to liquid impacts helps understanding the scaling effects, which is essential in the study of sloshing essentially based on small scale model tests.
