SOLAS Explained: Why Anti-Spray Tape is Mandatory in Ship Engine Rooms

I. Mandatory SOLAS Requirements

The SOLAS Convention is the most important international legal instrument for maritime safety. With regard to fire hazards in ship engine rooms, Chapter II-2 (Fire Protection, Fire Detection and Fire Extinction) sets out clear and specific requirements:

• Core Provisions: Under SOLAS regulations II-2/15.2.11, 15.3, 15.4, and 15.5.1, fuel oil piping systems must be adequately protected to prevent high-pressure spray of fuel, lubricating oil, or other flammable oils in the event of pipe or valve rupture or leakage.
• Purpose of Protection: The primary aim is to shield hot surfaces (such as exhaust pipes, boilers, thermal oil heaters, etc.) or other potential ignition sources, ensuring that even if a pipe fails, leaking fuel does not come into contact with hot surfaces, thereby preventing engine room fires.
• System Requirements: For external high-pressure fuel delivery lines between high-pressure fuel pumps and injectors, the Convention also requires a jacketed pipe system or equivalent shielding, along with a fuel leakage alarm, to ensure that any leaked fuel is safely directed to a drain tank or other safe location.

II. Key Applications of Anti-Spray Tape

To meet SOLAS requirements, anti-spray tape serves as an efficient and flexible pipe protection material widely used in ship engine rooms and various industrial diesel piping systems. Key application areas include:

• Pipe Flanges and Joints: Flange and threaded connections on fuel oil filling lines, fuel supply lines, lubricating oil lines, and hydraulic lines.
• Valves and Fittings: Various control valves, pump fittings, and other vulnerable points in the piping system.
• Around High-Temperature Equipment: Piping areas near hot surfaces such as steam pipes, thermal oil pipes, exhaust gas pipes, high-temperature silencers, incinerators, and electrical equipment.

By tightly wrapping anti-spray tape around these critical points, a high-pressure and high-temperature resistant sealing layer is formed, effectively mitigating the risk of high-pressure spray in the event of pipe rupture.

III. Why Classification Society Certification is Crucial

When sourcing marine anti-spray tape, classification society certification is the "passport" for use on board. SOLAS not only specifies protection requirements but also mandates that materials be tested and approved by recognized authorities.

• Main Certification Bodies: Compliant marine anti-spray tape must be certified by internationally recognized classification societies, such as ABS (American Bureau of Shipping), CCS (China Classification Society), DNV (Det Norske Veritas), BV (Bureau Veritas), LR (Lloyd's Register), NK (Nippon Kaiji Kyokai), and RINA (Registro Italiano Navale).
• Fatal Risk of Non-Certified Tape: Using non-certified anti-spray tape can lead to serious findings during Port State Control (PSC) inspections or annual class surveys. This may result in vessel detention, fines, or immediate replacement of all non-compliant materials, causing significant financial losses and schedule delays.

IV. Conclusion

In ship safety management, compliance is the baseline, and safety is paramount. Anti-spray tape is more than just a roll of industrial tape—it is a critical line of defense in the engine room fire protection system. For ship managers and procurement professionals, understanding the relevant SOLAS provisions, strictly selecting anti-spray tape with authoritative classification society certification, and ensuring proper installation are key measures to guarantee safe vessel operation and prevent fire incidents.
