CRYOGENIC INSULATION S-STUD®
CRYOGENIC INSULATION

S-STUD®

TIG KOREA’s composite spray foam insulation is designed as a non-bonded system that effectively accommodates the thermal contraction and expansion behavior unique to LNG cargo and fuel tanks.

The S-STUD® system offers broad compatibility with various tank geometries and containment types (Type B, and C tank) and can be tailored with a selection of cladding options to suit project-specific requirements.

With over 30 years of engineering expertise in cryogenic insulation, S-STUD® exemplifies TIG KOREA’s dedication to performance, durability, and continuous innovation.

S-STUD® Insulation System

01Non-Bonded System
The S-STUD® concept is a non-bonded insulation system that is mechanically anchored to the tank structure. This design significantly reduces structural stress and eliminates the risk of stress-induced cracking or delamination between the foam and tank surface—common issues in bonded systems. These risks become more pronounced with thicker insulation layers and lower service temperatures.
02Anchoring System
A highly robust anchoring system forms the backbone of the insulation structure, ensuring exceptional stability. This design effectively prevents cracking and other structural failures typically encountered during transient phases such as tank cooling and warming cycles.
03Leakage Detection System
An integrated continuous inter barrier space between the insulation layer and tank surface acts as a dedicated gas detection channel. This allows for early identification of cryogenic liquid leaks and ensures safe containment and controlled disposal of any leaked substrate.
04Seamless Polyurethane Spray Insulation System
An advanced insulation technique that reduces boil-off rates by using seamlessly spray-applied polyurethane foam, reinforced with a durable polyurea coating. This system delivers excellent thermal performance and durability

Proven Advantages Over Panel and General Spray Insulation

TYPE B TYPE B
TYPE C TYPE C
Item S-STUD® Insulation Panel Insulation General Spray Insulation
Type Non-Bonded Non-Bonded Bonded
Workability Less prefabrication time and significantly reduced installation time compared to conventional panel type insulation systems Long prefabrication time and requires significant storage area at the shipyard Less prefabrication time and significantly reduced installation time compared to conventional panel type insulation systems
Heat Ingress Less heat ingress compared to conventional panel type insulation systems Larger heat ingress due to joint between each panel Less heat ingress compared to conventional panel type insulation systems
Crack/Delamination Strong in terms of crack and delamination; minimized load and thermal stress Higher risk of crack and delamination in panel joints Weak in terms of crack formation as it is bonded to the tank surface
Delamination Strong in terms of delamination Strong in terms of delamination Weak in terms of delamination
Leak Protection/Detection Enhanced leak protection / detection through a continuous annular space throughout the whole tank surface Enhanced leak protection / detection through a continuous annular space Limited leak protection / detection through a channel-like annular space
