LNG Storage Tanks
A 1 Day Course on
Overview
In the realm of LNG logistics, while numerous courses focus on its transportation via ships, fewer focus on crucial aspects of LNG storage tanks at import/export terminals. This one-day course offers a comprehensive insight into the basic design, construction, and operation of LNG storage tanks, expounding on the fundamentals of cryogenic storage and the safety features inherent in above-ground LNG tanks.
Aligned with industry standards such as API 625, API 650, and API 620, which govern large, welded, low-pressure storage tanks including LNG tanks, this course delves into the intricacies of tank design and construction without endorsing specific manufacturers or equipment. Instead, it aims to familiarize participants with the diverse array of tanks available internationally.
Participants will gain a thorough understanding of:
- The basic design and construction of LNG storage tanks, including materials and equipment specifications
- The process of transferring liquid gas to LNG tanks from ships and subsequent re-gasification
PRIMARY AREAS OF FOCUS
- Understand LNG tank design basics including structural integrity
- Explore industry standards of API 625, API 650 & API 620, for large, welded, low-pressure storage tanks/LNG Tanks
- Learn seismic safety measures and containment strategies
- Explore quick construction methods of slip forming and air-raising
- Study 9% Ni steel and concrete for durability
- Optimize boil off, re-gasification and insulation
- Focus on testing and instrumentation for quality control & risk mitigation
- Apply knowledge to LNG operations, project management, and engineering
Who Should Attend
This course is particularly beneficial for individuals involved in LNG import or export terminals and is also relevant for those new to the LNG industry including storage tank design engineers, construction managers, environmental & health safety specialists, regulatory compliance officers, maintenance engineers, cryogenic tank operators, and inspection and quality assurance officers.

Programme at a Glance
Introduction to LNG
• Single Containment
• Double Containment
• Full Containment
Single - consists of a single wall or shell enclosing the LNG storage volume. Double - consists of an inner tank (primary container) surrounded by an outer tank (secondary container), providing an additional layer of protection against leaks or spills. Full - features both an inner tank and an outer tank, with the space between them serving as a containment area. This design offers the highest level of safety and environmental protection.
• Base Slab
• Piled
• Insulation
The base slab provides a stable foundation for the LNG tank and distributes the load evenly to the underlying soil or piles. Piles are driven deep into the ground to support the weight of the LNG tank and transfer loads to deeper, more stable soil layers. Insulation may be applied to the tank foundation to minimize heat transfer from the ground and prevent frost heave or settlement
• Internal 9% Ni Steel
• External Prestressed Concrete
• Insulation
The internal shell of the LNG tank is typically made of 9% Ni steel to withstand low temperatures and maintain structural integrity. The external shell of the LNG tank may be constructed using prestressed concrete to provide additional strength and protection against environmental factors. Insulation is applied to the tank shell to minimize heat transfer and maintain the cryogenic temperature of the LNG inside
• Inner Suspended
• Outer Reinforced Concrete
• Insulation
The inner roof is suspended from the top of the tank shell and may be insulated to prevent heat ingress. The outer roof is typically made of reinforced concrete and provides protection against weather and external forces. Insulation is applied to the tank roof to minimize heat transfer and maintain the low temperature required for LNG storage.
• Hydrotest
• Boil Off
Assesses the structural integrity of the LNG tank by pressurizing it with water to a specified level and checking for leaks or deformation. Boil off maintains safe operating conditions and prevents excessive vapor pressure buildup
• Includes sensors, gauges, and control systems installed on the LNG tank to monitor parameters such as temperature, pressure, and liquid level
• Equipment fitted include valves, fittings, and connections used for loading, unloading, and transferring LNG to and from the tank
Attend This Event With a Two-Day Course on
This two-day workshop will provide a basic understanding of storage tanks, how they are operated, managed and maintained, and explain the concept of vapour emissions and how to measure and control them on existing and new-build tanks, in order to ensure a safe and environmentally acceptable storage tank facility.
