1. LNG Carrier
 |
 |
 |
LNG carrier is used to ship natural gas
liquidated at 162℃below zero from gas
producing nations to consuming nations. Since
the low-temperature LNG is stored next to
engine room with a temperature of 510℃,
sophisticated ship construction technology
is required to prevent possible explosions. |
|
Materials used for various types - TGZ Type
(stainless steel), GT Type (36% Ni steel),
MOSS Type (aluminum) |

LNG Types
2. Land Delivery Base
|
For
LNG storage, several bases are set up in coastal areas.
Domestic delivery bases: Pyungtaek, Incheon, Anjung (Tongyoung),
Gwangyang.
Materials
used by steel type- Membrane Type (STS), Double Wall Type
(9% Ni steel) |
|
 |
|
POSCO earned a quality certificate for its
STS products, which can be used as LNG ships
and land delivery base tanks, from Franch
GTT, a membrane-type LNG facilities engineering
company, in November of 1995.
