OUR GREEN VISION
- Torgy LNG aims to contribute to the reduction of CO2 emissions within the marine sector by offering energy efficient LNG supply and containment systems
- We are constantly developing our offering to cater to market needs and have developed ammonia ready fuel and containment systems for vessels
- Our LNG A tank (and C tank) can be delivered as ammonia ready
OUR DEFINITION OF AMMONIA READY
- Minimum conversion time
- Completely ammonia ready tanks including:
- The tank itself
- FPR / TCS and its equipment
- Pumps within the tank
- Plug and play skids for ammonia conversion
- Ammonia ready piping, enclosures and bunkering systems
AMMONIA PROPERTIES AS FUEL
- NH3 energy density is much lower than LNG -> larger storage capacity, fuel pipes & equipment capacity requirement
- Ammonia as liquid fuel - system comparable to LPG – FGSS
- Ammonia as gas fuel - system comparable to DF set-up
- Safety concerns due to toxic NH3vapour
- Large quantity of pilot fuel (>7 %) required due to poor ignition properties
- Material compatibility issues with commonly used engine components made of nickel & copper alloys

CCS is divided into A tank and B tank.
TORGY USE WELL PROVEN IMO A TANK TECHNOLOGY IN A NEW APPLICATION
1. Well proven LPG
technology－non-pressurized
(0.7barg)
2. Independent tank
type – utilising standard ship construction practices
3. Customizable
shape - ideal for optimising tank capacity
4. Inspection is
possible from all sides of primary barrier
5. Secondary
barrier - unique and patented system is made of thin 304L
material to allow for fast and cost effective installation
Our unique and patented secondary barrier system is made of thin 304L material to allow for fast and cost effective installation.

Floating & Land-based LNG Storage, Power Barge & FSRU
- Fully metallic gas and liquid tight secondary barrier
- Continuous integrity check of a liquid- and gas-tight secondary barrier, with continuous HC-sniffing in an inerted hold-space
- DNV endorsement
- Easier installation procedure &
material handling
- Secondary barrier integrity can be
checked during installation period
thus shortening installation duration
- Easy repair procedure for secondary
barrier & insulation
- Support legs that do not need
inspection during tank lifetime
- Cold bridge from tank limited due to
ASEPlas material use
1. Up to 98 % loading possible for A-tank
2. A-tanks are more volume efficient as due to unique geometry, it can store 30-40 % more LNG in same cargo space

Material and installation speed
Time-saving several weeks and reliability.
For example welding (installation) speed with laser welding up to 1 m / minute for the secondary barrier.
Ideal for both fuel tanks and short/medium voyages with multiple stops.
Lower weight in medium sizes and for fuel tanks
1. Adopting mature
hybrid panel structure
2. IMO B tank is a
non-pressurized (0.7 barg), prismatic tank, held in position by steel supports
3. Equipped with
anti-sloshing bulkhead, effectively reducing the effects of sloshing and
fatigue
4. There is no
expensive pump tower, the submersible pump is supported by the bottom girders
5. Tank material:
aluminum alloy 5083-O (priority)
6. Dome structure
is near the center of the top, and the piping interface is centralized in it
7. Only partial
secondary barrier required
The main structure and internal
structure of the LNG storage tank are made of aluminum alloy 5083-O (the lowest
design temperature (MDT) is -162℃). And friction
stir welding and MIG welding are adopted for tank fabrication.
The B tank
has a wide range of applications, which can be used on the sea or on the land.
The size of the tank can cover almost all size requirements, from a few hundred
cubic meters to a large storage tank of 60,000 cubic meters. It can be used for
LNG transport ships, LNG bunkering ships, FLNG, FSRU, LNG powered transport
ships, LNG powered ships/barges, and onshore LNG tanks.

Compared with the
Comparison A, B, C and membrane tank types
1. Shell welded by friction stir welding, a method applied in aero space technology
2. Lower welding temperature and lower heat input are required
3. Single pass welding can weld aluminum alloy materials with a thickness of 0.8~100mm; double pass welding can weld 180mm thick butt plates
4. It has incomparable advantages in mechanical properties and construction efficiency
5. Fatigue properties are generally better than those of fusion welded joints
6. No additional weight is added
7. Less welding defects
- Improve accuracy, quality and reliability of construction
- Tank and hull can be built simultaneously, which greatly shortens the construction period
With anti-sloshing structure
NO loading limitation
Membrane type tanks can only load > 90% or < 10%
- Almost equivalent to the membrane type
- Volume utilization ratio is much higher than that of spherical tank (more than 40 %)
Plate thickness is~20 mm - hard to be destroyed.
- Light weight
- Low construction cost
Application of FSW welding technology
- New composite materials
- Effectively reduce stress concentration
- Support structure is at the bottom of tank bottom
- Simple connection structure with tank body
- Excellent insulation and heat preservation effect
- Replace the laminated wood
- Improve stress resistance
- Improved shear strength
