Shear-Water Project

"Shear-Water" – Ballast-Water-Free LNG Feeder & bunker vessel

The world-wide use of Ballast-Water onboard ships remains a global environmental issue. As a major step forward, GTT has designed, tested and validated an innovative ship-concept for safe navigation without use of any ballast-water.

This webinar gives you an introduction, presents the design, the solutions and shows the extensive test program with key results.

Bureau Veritas as Classification Society will share their perspective, and The Hamburg Ship Model Basin HSVA gives further insights from the test campaign.

Improving vessel energy efficiency with enhanced BOG management

To accompany LNG as marine fuel of choice, GTT has adapted its business model to facilite membrane tank integration inside LNG fuelled vessels. This flexible posture has been key to GTT success with many vessels currently sailing, knowledge available and guidelines at disposal to improve operation and safety of any future LNG ship.

Those Guidelines cover tank interfaces betterment, possible evolutions of containment system configuration and thermal performances (MarkIII, MarkIII Flex, 700 mbarg or 1 barg feature), adding to specific tips on chain gas architecture and equipment. implementation of Recycool, a key boil-off management feature, is also regarded. Such equipment is subject to ease operations, improve energy efficiency and reduce overall carbon footprint.

Membrane tanks for LNG fueled ships - Increased pressure up to 2 barg


Delivered in July 2021, Le Commandant Charcot, PONANT’s luxury exploration cruise ship, is equipped with two LNG tanks featuring GTT Mark III technology.

Those tanks have been improved to sustain a maximum pressure of 2 bar gauge (barg), offering significant advantages, from environmental considerations to additional operational flexibility in a safe manner.

Increasing operational window for FSRU and FLNG units


Offshore units (FLNG or FSRU) are loaded by LNG carriers during ship-to-ship operations. During this process, the LNG carrier tanks go through all filling levels, from high to low. 

In order to improve the operation window of the offshore units, GTT provides a unique digital solution for live sloshing risk prediction based on the weather forecast, the ship particulars and the operating conditions.

Key to successful bunkering operations

Charcot Bunkering

GTT, PONANT and GASUM will share their return on experience on the successful bunkering operations on Le Commandant Charcot, highlighting all the key decisions to take from concept design phase to hoses connection on the bunkering day.


Jean-Benoît Bensoussan (GTT), Grégoire Hartig (Gasum), Martin Cato Pettersen (Gasum) & Sébastien Luis (Ponant)


Future-proof membrane tank solution for LNG fuel PCTC market


GTT has developed an innovative, efficient and future proof solution for PCTC as an alternative to the usual Type C arrangement.

This webinar is the opportunity to show latest PCTC market review insights and dive into the most valuable technical aspects such as overall compactness and increase pressure setting (2barg).

LNG On-shore storage : Minimizing environmental impact & the effect of high material costs


The surge in the demand for new LNG facilities in the context of constant search to reduce environmental impact as well as rising cost of raw materials (Nickel for example), makes the selection of membrane full containment tank more and more attractive for LNG land storage.

Latest updates on the ongoing constructions will be shared including the world’s largest membrane full containment LNG tanks.

LNG as a fuel : Long Range VLCC



Currently in the doldrums, Very Large Crude Carriers (VLCC) shipbuilding market is expected to rebound by the end of 2022.

In partnership with major shipyards from China and Korea, GTT (Gaztransport & Technigaz) has developed several designs for long-range LNG-fuelled VLCCs. Fuel tank integration in the vessel has been optimized in order to take full advantage of the Mark III system, offering enhanced trading flexibility and reduced #OPEX.
