60 seconds between life and death, all it takes is a single “blocking plate”?

In July 2020, a propane leak suddenly occurred in the cargo hold of an LNG carrier, instantly igniting a 1200°C flame! The fire quickly spread through cable penetrations, endangering the entire ship! In this critical moment, the TST SEAL modular fireproof sealing system stepped in. For 60 minutes, the backfire surface temperature remained below 140°C, successfully blocking the fire’s spread path and allowing all 28 crew members to evacuate safely with zero casualties! This “backfire miracle” reaffirmed the core strength of TST SEAL’s A-60 fireproof sealing modules in the global shipping industry!

I. Quadruple Classification Certification: A Globally Recognized “Safety Pass”
In the field of ship safety, a single certification is no longer sufficient to address complex navigation environments. The TST SEAL A-60 fireproof sealing module, with its superior performance, has been simultaneously certified by four authoritative organizations: Russian Maritime Register (RS), China Classification Society (CCS), American Bureau of Shipping (ABS), and Bureau Veritas (BV), becoming a truly “global safety standard.”
RS certification: Meets the frost heave and fire protection requirements for ships operating in extremely cold waters at -50°C;
CCS certification: Meets the stringent fire resistance and structural strength tests of Chinese shipbuilding regulations;
ABS certification: Passes the extreme tests of US maritime standards for blast shock and thermal cycling fatigue;
BV certification: Qualifies for European market access, meeting both EMC and environmental requirements.
This means that whether sailing in the Arctic, on South China Sea islands and reefs, or on transoceanic routes, the TST SEAL module can provide comprehensive protection.

II. LNG Ship Operations: How to Stop the “Propane Explosion Chain”?
In the aforementioned LNG ship accident, propane gas entered the engine room through a cable penetration. If ignited, the result would be a devastating explosion. How did the TST SEAL modular system save the day?
Rapid response: The moment a fire broke out, the module’s outer material rapidly expanded, sealing all gaps.
Ceramic insulation: The internal material transforms into a ceramic-like hard shell at temperatures exceeding 800°C, reducing thermal conductivity to 0.03W/mK.
Structural stability: The stainless steel frame maintains its integrity; even if the front melts, the back-of-fire surface remains intact.
Result: The fire was contained to the cargo hold, buying valuable time for firefighting and evacuation! A joint RS and CCS inspection confirmed the integrity of the sealing system, requiring no replacement, and the vessel resumed service immediately.

3. More Than Fireproof: Comprehensively Protecting Ship Lifelines
The TST SEAL A-60 module is more than just a “firewall”; it’s an “all-around defender” of ship safety:

Explosion-proof and Shock-Resistant: Passed ABS explosion pressure testing and can withstand 5 bar overpressure shocks;

Salt-Spray Corrosion-Resistant: Constructed of 316L stainless steel and EPDM rubber, it passed the BV 1000-hour salt spray test and showed no corrosion, making it suitable for ocean voyages;

Rodent-Proof and Shock-Resistant: High-hardness materials resist rodents and withstand 10-500Hz vibration, ensuring long-term cable stability;

Electromagnetic Shielding: 42-63dB EMI attenuation prevents signal interference affecting navigation systems, complying with CCS electromagnetic compatibility standards.

4. Cost Revolution: 30 Years of Maintenance-Free, 30% Annual Savings!

Traditional plugging requires replacement every five years, requiring costly suspension of service, demolition of the wall, and re-filling. The TST SEAL sealing module:

Maintenance-free design: Up to 30 years of service life, no regular replacement required;

Quick installation: Modular assembly allows three people to complete a traditional five-day project in two hours;

Easy expansion: Later cable additions can be made without structural damage, simply by expanding on one side.

Measured data: After using it on a VLCC tanker, maintenance costs dropped by 30% over 10 years, resulting in a comprehensive benefit exceeding 10 million yuan! Furthermore, after passing long-term reliability assessments by ABS and BV, insurance premiums were reduced by 15%!

Between the raging waves and blazing smoke of the blue planet’s oceans, a small sealing module can become a life-or-death barrier. The TST SEAL A-60 fireproof sealing system is not only endorsed by the four major classification societies, RS, CCS, ABS, and BV, but has also proven its fire-resistant capabilities in real fire scenes.

“Safety is never accidental; it’s the meticulous protection of every detail.”

TST SEAL builds an insurmountable “Great Wall of Fire Protection” for every vessel sailing high above the sea.
