Few words on GTTWho we are

Inventor of the membrane containment system 50 years ago

We provide the containment systems technology to the main shipyards building LNG Carriers

400 LNG Carriers equipped with our systems

Polar Alaska: first LNC Carrier to enter in Yokohama in 1969

Tank commissioning of a 174,000 m3 LNG Carrier

Inherent safety of the system

With the increasing number of LNG propelled ships ( LNG fueled ships, bunker barges), collision must be add ressed

Collision case tested with DNV-GL, TUHH (University of Hamburg-Harburg)

Marc Van de Velde, July 2009

Collision simulation

Hamburg University - DNV GL - GTT cooperation programMembrane can adapt to very large deformations which could occur during a collision case without loss of tightness .

TUHH LAB TEST

Collision simulation

Test interpretation :

With 24m span, this would be equivalent to a 8m penetration of the inner hull, with NO loss of containment

In term of collision energy: ~1250MJEquivalent to a vessel of 100,000T at 9.8knots

Membrane resistance is very large, thanks to its inherent capacity for deformation (flexibility)

Therefore, the membrane can adapt to very large deformations which would occur during a collision case without loss of tightness

Ship to Ship transfer2

Ship-To-Ship transfer is not a conventional operation

Objective is to safely boost the transfer rate to reduce the duration of operation

Usual practice for some Shipowner

Optimization of ship to ship transfer

LNG as a Fuel market specificsScale impact : Limited capacity & limited equipment onboard

Frequency impact : LNG transfer will become a daily operation involving operators from various backgrounds

Safety issues : Zero venting policySafety and security zone
