Transforming Mid-Scale Liquefied Gas

The Mid-Scale Type B Containment Solution

The SSRC Type B patented containment technology is conceived to address the needs of the mid-scale liquefied gas markets. It provides excellent thermal performance, low weight and ease of fabrication. In cooperation with world-renown Moss Maritime AS, SSRC Technologies introduces a novel Type B containment system specifically designed for the mid-scale LPG, NH3, Petchem and LNG markets. The SSRC system is also uniquely suited to scalable floating storage and regasification solutions, enabling quick and economical implementation of mid-scale LNG import terminals.

The SSRC Containment System

The Side Supported Reinforced Containment (SSRC) technology is a unique, patented Type B containment system designed to first principles for the safe carriage of all types of liquefied gases.

Multiple ring frames and external supports permit single tank capacities of up to 15,000 m3. The unique arrangement of the support bearings effectively decouples hull and tank deflections while distributing the tanks loads evenly throughout the cargo hold. The supports are situated near the hull neutral axis where deflections are minimal and torsional stiffness is greatest. Anti-floatation devices are integrated into each support.

Due to its simple geometry and use of repeated elements, the SSRC is uniquely suited to serial production and semi-automated fabrication methods.


The SSRC containment system is capable of transporting all types of liquefied gases including LPG, NH3, ethane, ethylene and LNG. It is suitable for liquefied gas carriers from 12,000 m3 to 45,000 m3.

As a floating storage solution, the SSRC system offers rapid deployment and modular expansion to capacities of 50,000 m3.
