In ship engine rooms, subway substations, offshore wind power platforms, or data center underground cable entry rooms, traditional seal failure often means—downtime, wall demolition, excavation, days of emergency repairs, and hundreds of thousands in losses. Now, the TST SEAL modular sealing system is completely revolutionizing maintenance logic with its four major advantages: “fast installation, expandability, visibility, and manageability,” improving efficiency by 30%~70% and truly achieving “less downtime, less manpower, and less risk.”

1. 1. Rapid Installation and Replacement: Saving Time Means Saving Money

✅ No Custom Drilling Required, On-Site Installation and Use

Traditional Method: Requires precise measurement of cable outer diameter in advance, and factory-customized fixing hole sealing rings, with a cycle of 2–4 weeks;

TST SEAL Modular Solution: Uses peelable rubber blocks, which can be manually peeled to the matching size on-site, completing a single-point seal in 10 minutes.

📌 TST SEAL Case Study: A LNG shipyard reported that after implementing the modular system, the installation time for a single through-tank seal was reduced from 45 minutes to 8 minutes, saving over 200 hours of labor for the entire ship.

✅ Tool-free maintenance, lowering the skill threshold: Standardized bolt tightening design allows ordinary workers to operate the system after 15 minutes of training; No welding, glue injection, or baking is required, eliminating secondary pollution and safety hazards.

1. 1. Support for Future Expansion: Say Goodbye to “Drilling Holes”

This is the biggest pain point in operation and maintenance efficiency!

Adding sensors, communication lines, and backup circuits after project commissioning is commonplace, but once traditional seals harden, expansion equals destructive construction:

Traditional solution: Cutting the existing seal → Drilling new holes → Re-fireproofing and waterproofing treatment → Downtime 3–7 days;

TST SEAL modular solution: Loosening bolts on one side → Peeling off the new layer → Inserting new wires → Re-tightening → Uninterrupted power supply and no structural damage throughout the process.

📌 Real Data: During the renovation of the Berlin Metro U5 line, the sealing of the newly added signal line was completed in just 12 minutes, avoiding a complete line shutdown (daily loss of €500,000+).

III. Status Visibility + Predictive Maintenance: From “Repairing When It Breaks” to “Predicting Before It Breaks”

High-end modular systems are being integrated into the intelligent operation and maintenance ecosystem:

🔍 1. Digital Identity Binding

Each module comes with a QR code/RFID tag. Scanning the code allows you to view:

Installation date, location, and cable list;

Fireproof/watertight certification report;

Historical inspection records.

📡 2. Intelligent Sensing (Cutting-Edge Applications)

Pilot projects have integrated micro-sensors:

Humidity sensing: Early warning of water leakage;

Pre-tightening force monitoring: Determines the degree of rubber aging;

Temperature recording: Identifies nearby overheating risks.

Data is integrated into CMMS (Computerized Maintenance Management System), automatically triggering early warning work orders.

📌 Case Study: A certain offshore wind power booster station detected a potential seawater leak in advance through humidity monitoring of its sealing modules, preventing a transformer short circuit and saving €180,000 in maintenance costs.

1. 1. Standardized Inventory Management: Reducing Spare Parts Types by 70%

Traditional Model: Requires stocking dozens of types of fixing hole sealing rings, such as Φ10, 15, 20…50mm;

TST SEAL Modular Model: 1–2 universal modules cover the entire Φ10–150mm range, reducing inventory SKUs by 80%;

Reduces warehousing costs and eliminates the embarrassment of “having equipment but no spare parts”.

1. 1. TST SEAL Sealing Module System Improves Safety and Compliance Efficiency

Unified Certification System: The entire system is certified by DNV, EN 45545, GB/T 9978, etc., and acceptance documents are generated with one click;

Traceable Installation Process: Intelligent wrenches record torque data and automatically generate compliance reports;

Reduced High-Risk Operations: No need for hot work or high-altitude wall drilling, reducing the accident rate.

1. 1. Comparison of Efficiency Improvements in Typical Industries Using the TST SEAL Modular Sealing System

Industry Traditional Sealing Maintenance Pain Points TST SEAL Modular System

Shipbuilding Repairing through-tank seals requires dry-docking No disassembly required, saving 3-15 days of construction time

Metro High risk of substation capacity expansion and shutdown Uninterrupted power supply for cable addition, ensuring operational continuity

Wind Power Short maintenance window for offshore platforms Rapid replacement, seizing the 24-hour work window

Data Center Water leakage in the incoming line room leading to downtime Early warning + rapid repair, reducing MTTR (Mean Time To Repair) by 60%

The modular sealing system is not just a material upgrade, but a revolution in operation and maintenance. It transforms “passive response” into “proactive control,” “experience-dependent” into “data-driven,” and “cost center” into “efficiency engine.”

As one rail transit operations manager put it: “We used to fear rerouting, now we look forward to upgrades—because replacing the TST SEAL seal is faster than changing a cup of coffee.” In the future, with the deep integration of digital twins, the Internet of Things, and green manufacturing, this small TST SEAL sealing module will continue to inject new momentum for efficient, safe, and sustainable operations and maintenance into global infrastructure in unseen ways.
