COSTAL AND PORT STORAGE SOLUTION
While the logistic and storage facilities for large LNG volumes intended for the supply of the gas grid at national level are well in place thanks to large LNG import terminals and large LNG carriers, the distribution and storage of smaller volumes of LNG intended for use as fuel on ships are only in their infancy. GTT membrane technologies are already available for building storage facilities of small to medium size (typically 5.000 m3 to 30.000m3 or more).
CYLINDRICAL FLAT BOTTOM METALLIC OUTER CONTAINMENT
Target Capacity: from 2k to 30k m3
- Metallic outer tank
- Without secondary barrier
- Single containment
- Associated to a simplified membrane arrangement
- Sump is a relevant option
CUBIC METALLIC OUTER TANK
Target Capacity: from 2k to 10k m3
- Metallic outer tank, simple design easy to prefabricate
- Membrane system similar to LNG carriers
CONCRETE PREFABRICATED SOLUTION
- Precast concrete pieces for surrounding structure
- Horizontal assembly
- Insulation and membrane pre-assembly on concrete surfaces in factory
NEAR SHORE SOLUTIONS
- Geometric adaptability minimizing footprint and maximizing storage
- Low pressure containment eliminating the risk of BLEVE (boiling liquid expanding vapor explosion)
- Flexible choice of construction method: building onsite or pre-fabricate
The Ship-to-Ship LNG transfer solution is a key element of the supply chain of LNG as fuel. Although similar systems already exist in the offshore industry, they appear to be quite complicated and unsuitable for LNG Bunkering.
GTT has developed REACH4TM, an innovative adaptation of a well proven system, already used for bunkering of conventional fuel. REACH4TM is designed to fit on the LNG bunker vessel, permitting a simple and safe transfer of LNG fuel to a client vessel.
The bunker mast has been adapted to LNG constraints, with pipes suitable for cryogenic conditions and a reinforced structure. It is well-suited to bunker most ships, whatever their bunker station arrangement and can be also used to load the bunker vessel.
