Full Containment LNG Storage Tank (PC-LNG Tank)

DGPS: Leading the Development of Full Containment LNG Storage Tanks, Standards, and Innovative Storage Solutions

Overview

Full Containment LNG Storage Tanks—also known in Japan as PC-LNG Tanks (Prestressed Concrete LNG Tanks)—are a cornerstone of the LNG industry. These tanks provide safe, efficient, and cost-effective solutions for the storage and transportation of liquefied natural gas. They play a critical role in meeting global energy demands by offering increased storage capacity, lower operational costs, and enhanced safety and efficiency.

Why DGPS?

Pioneering Innovation:

Daigas's Group developed the world’s first and at the time largest 180,000m³ PC-LNG tank and completed a record-breaking 230,000m³ storage tank in 2015, demonstrating leadership in LNG technology.

Commitment to Safety:

From advanced welding technologies to comprehensive risk management systems, we prioritize safety across all aspects of LNG tank design and operation.

Cost-Effectiveness:

DGPS innovated the world's first 7% Ni steel technology, reducing costs while maintaining high safety standards.

Global Expertise:

Leveraging extensive operational experience, we provide tailored solutions that optimize performance and reliability for LNG storage and transportation projects.

Features

Suspended deck tanks have lightweight aluminum or stainless steel decks hanging from the roof of the inner tank, which is vertically cylindrical with a flat bottom. The outer shell consists of a thin metallic liner.Double dome PC-tanks feature a dual-layer structure consisting of an inner tank and an outer shell, providing superior seismic resistance. The roof and sidewalls of the inner tank are firmly connected to mitigate sloshing (intense liquid oscillation caused by earthquakes), effectively securing the liquid.

Increased Capacity:

Our tanks maximize space utilization through advanced capacity expansion technologies, using 50mm thick 9%Ni & 7%Ni steel with cutting-edge welding and inspection methods for strength and durability.

Safety and Cost-Effectiveness:

The development of 7% Ni steel technology ensures both safety and cost-effectiveness in LNG operations.

Remote Monitoring and Maintenance:

Advanced systems for monitoring and maintaining LNG tanks enhance safety and lifespan, supported by a comprehensive risk management system.

DGPS is committed to providing innovative and reliable solutions for the LNG industry, ensuring our clients achieve the highest levels of safety, efficiency, and profitability.
