Tester Technology Appears at 2025 Global Marine Chain Conference Modular Sealing System

Published: 2025-11-09Views:0

The OEEG Global Offshore Chain Conference, co-sponsored by the Shanghai Shipbuilding Industry Association and the China Deep Sea Offshore Engineering Equipment Technology Industry Alliance, recently came to an end in Shanghai. With the theme of "reconstructing the marine ecosystem from a global perspective", this event will build an efficient bridge between the "going global" of China's marine supply chain and the "deep cultivation of the Chinese market" of global project parties.As a national-level high-tech enterprise and a national-level specialized and new "little giant" enterprise, Tester Technology brought its self-developed localized modular sealing system to this event, demonstrating the technical strength of domestic high-end equipment.


Focus on subdivision areas: technological breakthroughs in domestic substitution

During the exhibition, the booth of Tester Technology attracted the attention of many professionals in the field of marine engineering. The modular sealing system highlighted by the company is an innovative solution developed for the sealing needs of cables and pipelines for ships and offshore equipment.



The modular sealing system on display hasClass A- 0/A-60 fire resistanceandIP68 protection class,canEffectively prevent water and gas from penetrating the sealed bulkhead, while providingElectromagnetic shielding capability up to 18GHzandExplosion-proof, anti-vibration shockSuch as comprehensive protection performance. Its"Strippable reducing" designSupport the adaptation of different specifications of cables and pipes,30% increase in installation efficiency and support for "zero downtime" maintenanceSignificantly reduce the cost of operating offshore platforms. As an alternative benchmark for localization, the system has passed CCS (China), ABS (USA), BV (France), RS (Russia), RINA (Italy)The world's top five classification societies and the Marine Equipment Directive MED certification,The technical standards are flush with international brands, breaking the long-term dependence on imports in the high-end sealing field.




The representative of Tester Technology said that with the development of the global offshore industry to the deep sea and the open sea, the requirements for the safety and reliability of equipment are increasing. The company's modular sealing system has been successfully applied to a number of domestic and foreign offshore projects, product quality and technical services have been highly recognized by customers.

Domestic solution verified by global head customers


Tester system has been successfully applied to a number of major domestic offshore equipment projects:

  • CSSC LNG Carrier Fuel Tank Sealing:Solve airtight and explosion-proof challenges in low temperature environments;

  • Zhenhua Heavy Industry Offshore Wind Power Installation Platform High Voltage Cable Wear:Resist salt spray corrosion and high frequency electromagnetic interference;

  • Explosion-proof seal for CGNPC deep-sea semi-submersible platform:Meet the needs of A- 60-level fire prevention and deep-sea high pressure resistance.

Grasp Industrial Opportunities and Deepen International Cooperation

The conference brought together 5553 industry practitioners and 122 exhibitors from the global marine industry. Tester Technology has made full use of this international platform to conduct in-depth exchanges with leading domestic and foreign companies such as CNOOC, Petrobras, Jiangnan Shipbuilding, and Hudong Zhonghua.

The company's technical director pointed out that the current global marine industry is accelerating its recovery, especially in emerging fields such as LNG equipment and offshore wind power, and the demand for high-performance sealing products continues to grow.Tester will seize this opportunity, relying on the advantages of the Yangtze River Delta offshore industry cluster, continue to increase R & D investment, to provide global customers with better products and services.

Looking to the future development, help industrial upgrading

With the relocation of Shanghai East China and other chain main enterprises to Changxing Island, the cluster effect of Shanghai's offshore industry is further highlighted. Tester Technology will actively integrate into this industrial ecology, strengthen cooperation with upstream and downstream enterprises in the industrial chain, and jointly promote the localization process of key components of offshore equipment.


In the future, Tester Technology will continue to adhere to the development concept of "technological innovation and quality first", actively participate in global offshore industry cooperation, and contribute to the construction of an open, inclusive and win-win global offshore industry chain ecosystem.
