“LNG Block” building concept
(New built & Retrofit)
Block building Main manufacturing milestones
▶ The block containing the LNG tank is built
by a dedicated shipyard in its premises
▶ The membrane system is installed inside
the tank by the dedicated shipyard
▶ The FGS system is added to the block :
piping / pump tower / vent mast / relief
valves / HP pumps / vaporizers, …..
▶ The block is shipped to the shipyard in
charge of the overall vessel delivery
▶ The block is installed into the overall ship
(at 1st block keel laying stage).

Executive summary
Objectives :2barg increases flexibility during bunkering operations or idle conditions…
…with a marginal structural modification
Schedule:AIP from LR and BV (delivered in Oct.)
AIP from ABS (to be deliver at least in Nov.)
Studies with DNV-GL still under discussion
Next AIP to be issued : NO96 and LFS applications
Commercial topics:Flexibility is a driving parameter for LFS
For LFS: 2barg becomes one possible base case
2 barg is offered both for Mark and NO techno.

Context and purpose
GTT has developed the design for a LNG bunker ship 4k (AP460)With tank pressure set up at 700 mbarg
An AIP was obtained in September 2014
It is defined as a reference case
To give more operational flexibility, an alternativ e design (AP460B) is studied with the tank pressure set up a t 2 barg

Conclusions
GTT technologies are reliable, cost competitive and under w ell
adaptation to LNG fueled ship application:
2barg membrane (BOG management operations)
Mark FIT technology (volume efficiency)
New industrial execution plan (“LNG tank section package”)
1st bunker barge in US
GTT can bring its expertise during the whole life of the ship
Dedicated solutions can be developed with industrial partn ers support
in line with Client requirements
GTT is committed to bring solutions and value to th e LNG fuel chain
