Liquified Natural Gas (LNG) Transportation and Production
LNG is a crucial energy source, used for cooking, commercial processes, and power generation. To transport LNG, it is converted into a liquid form and stored in specialized tankers.
LNG Carrier Vessels
There are various types of LNG carriers, including:
- Moss type: spherical storage tanks for strong endurance
- Membrane type: optimized storage capacity for long-distance routes
- Floating Storage and Regasification Units (FSRUs): dual-purpose vessels for transport and regasification
- Q-Flex and Q-Max boats: large LNG carriers with low emissions
Floating Liquified Natural Gas (FLNG) Tankers
FLNG tankers are complex structures that extract, process, and liquefy natural gas at sea. The construction process involves:
- Assembling gas plant modules ashore
- Precise lifting of modules onto the vessel’s hull
- Connecting piping lines and wiring
- Installing a sophisticated refrigerant loop
LNG Tanker Operations
LNG tanker operations are essential for global energy supply. These vessels require:
- Cutting-edge technology for safe and efficient handling
- Experienced captains with technical knowledge and interpersonal skills
- Regular maintenance and cargo conditioning
LNG Transfer Process
The LNG transfer process involves:
- Highly planned and technological procedures
- Collaboration between vessels and floating storage units
- Connection of specialized hoses and cooling systems
LNG Facility Construction
Constructing an LNG facility requires:
- Large-scale undertakings with complex components
- Modularized systems and massive concrete structures
- Rigorous testing and safety protocols
