Description

Technical Field

[0002] Firewalls are important components for separating fire zones on offshore platforms, and they play a critical role in preventing the spread of fire. At present, the firewalls on offshore platforms mainly use fireproof materials + metal skin structure. A large number of angle steels and keel steel structures are required to fix the metal skin, which increases the load on the offshore platform. In addition, firewalls usually use a spliced ​​skin + sealant sealing structure. In the harsh marine environment, the sealant ages, and corrosive media invade the firewall, accelerating metal corrosion. Usually, most keels rust and rivets fall off within 3-5 years. After experiencing extreme weather such as typhoons and rainstorms, some metal skin splicing panels are even missing. Firewalls need to be maintained frequently, and the maintenance process is complicated.

[0003] Therefore, a lightweight offshore platform firewall structure that can avoid the use of a large number of steel structures, achieve lightweight firewalls, form a coherent and complete sealing layer, and effectively withstand the complex and harsh marine environment becomes the key to solving the problem.
