As an important carrier of modern maritime transportation and trade, the safety and reliability of ships are of vital importance. In the process of ship construction and operation, cable penetration sealing is one of the key technologies to ensure ship safety. The main purpose of cable penetration sealing is to prevent seawater, chemicals, grease, etc. from entering the cable penetration parts of the ship to avoid damage to the ship’s power system, communication system, control system, etc. Therefore, in-depth research on ship cable penetration sealing technology is of great significance to improving the safety and reliability of ships.

According to Article 9.2.3.3 of Chapter II-2 of SOLAS, the fire integrity requirements of bulkheads and decks of cargo ships other than liquid cargo ships, and the fire integrity of the adjacent space separation decks are arranged according to the requirements of Table 9.6 (as shown in the following table).

Among them, the deck fire integrity requirements for separating adjacent service spaces with a smaller risk of fire are marked as *. According to the annotation under Table 9.6: The * in the table means that the separation is required to be built with steel or other equivalent materials, but it is not required to be “A” grade standard. However, except for open decks, if the deck is penetrated to arrange cables, pipelines and ventilation ducts, the penetrations should be sealed to prevent flames and smoke from passing through.

According to the above requirements, the fire-resistant integrity of the deck separating adjacent cables should be constructed of steel or other equivalent materials, and the penetrations should be sealed to prevent flames and smoke from passing through.

1. Ship penetration sealing parts

On ships, modular cable penetration seals are flexibly used (taking the application of TST SEAL cable/pipe penetration sealing system as an example) to protect personnel and sensitive equipment from danger.

2. TST SEAL cable/pipe penetration sealing system

TST SEAL Technology can provide global customers with all solutions for cable and pipeline penetration in the ship industry. For many years, it has continued to focus on the upgrade and transformation of cable and pipeline modular sealing solutions, which can be used to solve the problems of pipeline penetration sealing, fire prevention and other problems of different functions and materials of ships, and ensure the safe and reliable navigation of ships.

Flexible adaptation to pipes of different sizes and materials

Peelable layer variable diameter technology, adaptable to pipes of different sizes. It can be used for all kinds of metal pipes, plastic pipes, alloy pipes, etc. in the hull or offshore structures, ensuring that certified protection is provided to the owner in accordance with official regulations and requirements, meeting the high requirements of fireproof, watertight and airtight.

High level of fireproof and sealing performance

TST SEAL sealing system can meet various sealing requirements such as fireproof (A0-A60), airtight, smoketight, waterproof, etc. It has the characteristics of vibration resistance, impact resistance, pull-out resistance, aging resistance (up to 40 years), insect and rodent resistance, chemical resistance, radiation resistance, UV radiation resistance, non-toxic, halogen-free, protection (IP68), etc.

Professionally tested and certified

TST SEAL has a standardized sealing module with peelable layer variable diameter technology, combined with a variety of metal frames, which can cope with various complex working conditions in the ship pipeline introduction area. The fireproof, sealing, dustproof, shockproof, explosion-proof, and electromagnetic interference-proof performance have all been professionally tested and certified.

Flexibility generates economic benefits

Standardized modules can be combined with products in a “building block” manner to design several pipe transit systems. It is extremely flexible and supports lossless addition or replacement of pipes, which can adapt to the needs of future pipeline transformation and expansion.

TST SEAL, the leader of domestic pipeline cable transit sealing systems! The products have passed the formal approval and factory approval of Russian Classification Society (RS) and China Classification Society (CCS), and have obtained certificates. At present, DNV, ABS, BV, MED, and RINA approvals are also progressing steadily.

TST SEAL has currently provided more than 3,000 sets of domestic cable and pipe penetration sealing solutions for Wison Group in the shipbuilding field, Mingyang Electric in the offshore field, State Grid, China Southern Power Grid, Huadian Group, Datang Group, Three Gorges Group, Dadu River Group in the energy field, and China Railway Construction and high-speed rail, subway and other well-known enterprises in the world such as 1,000+ listed groups, state-owned enterprises, and central enterprises in the rail transportation field.

Protect the safety of life and property and ensure the stable operation of equipment. In the future, TST SEAL will continue to uphold the customer-first philosophy and provide global customers with satisfactory and reliable pipeline penetration sealing products and solutions to help ships ride the wind and waves and sail far away.
