Offshore wind power fireproof plugging TST seal becomes the industry’s first choice with its hard-core strength

With the accelerated advancement of the global new energy strategy, offshore wind power is becoming a key track for energy transformation. However, offshore wind power facilities are exposed to extreme environments such as salt spray corrosion, high temperature, and vibration for a long time, and fire safety issues have become a pain point in the industry. Once the plugging of key components such as cables and pipelines fails, the fire will not only cause huge economic losses, but may also cause major safety accidents. In this context, TST seal technology’s offshore wind power fireproof plugging module stands out with its technological innovation and cost advantages, providing the industry with more reliable and economical solutions.

Technical barriers
Build “hard-core” protection

The core function of the offshore wind power fireproof plugging module is to seal cable holes, pipeline penetrations and other areas with special materials to prevent the spread of flames, smoke and harmful gases. In offshore booster stations, fireproof plugging and sealing are particularly important. The booster station is always facing the deadly threat of harsh environment: high concentration of salt spray is pervasive, accelerating equipment corrosion; huge wave impact and continuous vibration test the structural limit; extreme temperature change and high humidity environment induce condensation and erode insulation; there are also typhoon attacks and potential fire risks. These threats are like sharp blades, pointing directly at the precision electrical and control systems in the station – once the seal of the critical cable and pipeline bulkhead fails, seawater backflow, moisture penetration or flame spread will cause catastrophic accidents. Therefore, high-performance penetration sealing modules are by no means ordinary accessories, but a rigid requirement to maintain the lifeline of the booster station. Compared with traditional sealing materials, TST seal fireproof sealing modules have achieved breakthroughs in three dimensions:

01 Full qualification certification, building a solid safety line

TST seal fireproof sealing modules meet the A-0 and A-60 fire resistance levels in the “2010 International Fire Test Procedure Application Rules” (FTP Rules) standards. Not only do they meet the GB23864 standard levels, some models can currently achieve a fire resistance level of 3h; the watertight and airtight performance meets the pressure sealing requirements of 0.5MPa level; it can prevent the penetration of pressure levels, with a protection level of IP68, which can prevent water and gas from passing through, and also has noise reduction, corrosion resistance, vibration and shock resistance and other properties. In addition, the special electromagnetic shielding module has the ability to prevent EMI and EMP, ensure electrical safety and prevent electromagnetic penetration, and the explosion-proof module can be used in explosion-proof spaces of corresponding levels.

TST seal has successfully passed the strict certification of international authoritative classification societies such as RS (Russian Maritime Register) and CCS (China Classification Society). The product’s fireproof performance, explosion-proof level and adaptability to the marine environment have fully met the standards, ensuring the safety of offshore wind power. Simultaneously accelerate the qualification review of global mainstream classification societies such as DNV, ABS, BV, MED, and RINA to meet the project requirements of various working conditions.

02 Practical verification, reliability can stand the test

The TST seal fireproof plugging system has been successfully verified and applied in many key projects in the offshore wind power field with its excellent fireproof sealing performance and reliable long-term stability. The product has been stably used in many industry benchmark projects including the Zhangpu Liuao Phase II Offshore Substation Fireproof Sealing Module Procurement Project, the Three Gorges Yangjiang Shaba Offshore Substation Project, the Datang Nan’ao Offshore Substation Project, the CSIC Haizhuang Tower Project, and the Shantou Datang Lemen Phase II Project. In these offshore facilities with harsh environments and extremely high safety requirements, the TST seal module effectively builds a key safety barrier, which has won high recognition from the general contractor design unit and provided strong support for the safe and reliable operation of offshore wind power.

Taking the Datang Lemen project in Shantou, Guangdong as an example, the medium and high voltage equipment in the 300MW wind farm booster station is densely populated, and the fireproof sealing module needs to resist salt spray erosion and equipment vibration at the same time. Project practice shows that the TST seal penetration sealing module has excellent performance in high temperature tolerance, sealing stability and long-term durability, fully meeting the stringent requirements of offshore wind farms.

03 Costs dropped by 30%, and the benefits of localization were released

Compared with imported products, the TST seal penetration sealing module helps customers save 25%-30% of the comprehensive cost (including tariffs, logistics and maintenance costs) by optimizing the supply chain and technological innovation. For example, after a customer replaced the imported plugging materials, the overall project cost was reduced by 28%, and the after-sales team achieved a 72-hour emergency supply response, greatly shortening the fault handling time.

Technical breakthrough
From “trust gap” to “industry first choice”
In the early stage of domestic substitution, the product faced the challenge of “few cases and difficult trust”. In order to break through this bottleneck, Shenzhen TST seal Technology Co., Ltd. adopted a dual-track strategy: on the one hand, by carrying out extreme tests such as high-temperature combustion, mechanical impact, and salt spray aging, with strong noise reduction, corrosion resistance, vibration attenuation, and vibration shock resistance, the experimental data dispels customer concerns; on the other hand, relying on the rich project experience accumulated in the fields of onshore power, petrochemicals, etc., combined with the actual cases of booster stations, technical trust is gradually built. Today, with the successful application of more and more projects, TST seal fireproof plugging modules are winning market recognition with strength. In the future, we will continue to deepen technological innovation and provide a more solid “firewall” for the safe operation of offshore wind power.

Customer value
“Full-cycle escort” for cost reduction and efficiency improvement

The value that TST seal fireproof plugging module brings to customers is far more than cost savings:

Customized adaptability
TST seal provides customized sealing solutions according to different working conditions to ensure the plugging effect and construction effect;
Service agility
72-hour emergency supply capability + full life cycle technical support, from installation guidance to fault response, escort project operation throughout the process;
Risk controllability
Through authoritative certification and actual combat verification, the fire risk is reduced to a minimum, avoiding huge downtime losses caused by safety failures.

Customer testimony
Speak with data and prove with results

The main person in charge of a wind power project
When choosing a fireproof plugging supplier, we had doubts about the reliability of domestic products. But after many rounds of technical exchanges and solution comparisons, we finally decided to use the TST seal sealing system. After the project was implemented, not only did it pass the acceptance at one time, but it also saved 28% of the cost of the original imported solution. What’s more rare is that the after-sales team showed a very high response speed when installing equipment and supplementing materials, truly realizing “domestic substitution and quality upgrade”.

Conclusion
Domestic strength reshapes offshore wind power safety standards

Driven by the wave of “localization” and the demand for “cost reduction and efficiency improvement”, TST seal offshore wind power fireproof plugging modules are breaking the import monopoly with technical strength and winning market trust with practical results. In the future, with the verification of more projects and the iterative upgrading of technology, TST seal “domestic boutique” will continue to provide safer and more economical solutions for the offshore wind power industry, helping China’s new energy industry move towards the high end of the global value chain.
