Engineering Procurement, Supervision& Construction (EPC)
BANGLAMARK provides every scope of services in the construction of storage tanks and handling facilities for low-temperature liquefied substances such as LNG, Ethylene, Ammonia, Oxygen, Nitrogen, Hydrogen, Etc. (Low temperature ranging from -4 °c to -196°c). we have the resources and expert foreign Engineers to design and build LNG storage tanks in any location and under all types of logistical constraints. Our people have the localized knowledge to provide front-end permitting and regulatory compliance support all the way through startup. We direct-hire and train local field personnel whenever possible, and we can quickly mobilize large erection crews anywhere if they are needed. As a dedicated storage tank manufacturer, we offer full-process EPC (engineering, procurement and construction) including maintenance to achieve high-performance project execution for tanks and auxiliary equipment/facilities while leveraging the pricing and geographical advantages of manufacturing products.
These are part of our efforts to support the energy-related needs of people worldwide through energy-source storage facilities.
Type of LNG TANK
– Single Containment
– Double Containment
– Full Containment
Tank Containment system
Single Containment Storage tank:
This type of storage tank consists of only one container to store the liquid product. (Primary liquid container)
- The outer container is for the retention and protection of insulation and to constrain the vapor gas pressure but is not designed to contain the refrigerated liquid in the event of leakage from the inner container.
- Surrounded by a bund wall / dike wall to contain possible product leakage.
Double Containment Storage Tank:
This tank consists of a liquid and vapor tight primary container and secondary liquid container
- The secondary liquid container is designed to hold all the liquid contents of the primary container, but it is not intended to contain or control any vapor resulting from product leakage from the primary container.
- The annular space between the primary container and the secondary container shall not be more than 6m. (20 ft)
Above-ground double-shell metallic tanks
These tanks are of flat bottom, , cylindrical type, with outer shell of carbon steel and inner shell of low temperature service steel or of aluminium. Based on designs thoroughly studied for every aspect of assured prevention, the tanks are further as the highest security with the strict quality control enforced throughout all stages of manufacture and construction.
Above-ground double shell tanks with suspended deck
The outer shell is replaced by the high safety dike which is provided with a roof. Any leakage from the inner shell will be prevented from reaching the environment. Concrete is resistant to corrosion, and ensures long service life, while dispensing with paint coating Adaption of prestressed concrete with further enhance earthquake-resistance.
Above-ground triple shell tanks with concrete outer shell and double metallic inner shell
Independent primary inner tank inside the secondary inner tank provides for additional safety by containing all leakage from the primary tank within the secondary inner shell
A full containment tank consists of liquid tight primary container and liquid and vapor tight secondary container.
- The secondary container shall be capable of both containing the liquid product and controlling the vapor release in the event of product leakage from the primary liquid container.
- The annular space between the primary and secondary containers shall not be more than 2.0m. (EN 14620-1)
Satellite Terminals are smaller local terminals with a size of 100-20,000 m3, and located by the sea shore or rivers. They are often placed in harbors where there is easy access for supply vessels to fill the tanks. The storage is mainly built as bullet tanks. These terminals are often built primarily as bunkering facilities for ships, but they can also include additional services such as truck and container loading to facilitate distribution of LNG in liquid form. In larger sizes, a regasification unit supplying a local gas pipeline can also be added.
BANGLAMARK’s preference is to deliver these projects as EPC with full delivery and performance guarantees. The terminal can be supported with full service agreements.
Integrating all links in a chain
The past two years have been a wild ride for investors in the world’s biggest publicly traded oil companies. It is an essential part to improve the maintenance of industrial civilization in its current configuration, and thus it has become a critical concern for many nations. Gas is also considered as a large percentage of the world’s energy consumption.
In our country perspective, Banglamark- Corporation has become one of the most notable platforms in the field of Project Management, Sales & Service of various Oil & Gas Plant, Gas Equipment & the support services associated with our projects.
There is no shortage of energy being devoted to finding new and sustainable energy solutions. But new work scope also needs to be generated that will allow the grid to operate in a manner resembling the existing resources. Banglamark- Corporation paves a more organized way of assisting project management, generating more developed ideas, other support services in energy and power unit.
Banglamark- Corporation has established a strong reputation for executing large complex projects and providing emergency solutions to our clients. Our approach towards construction management is cost-effective and we try to deliver projects on time focusing on budget, quality service and safety measures.
