Refer to this post: http://bbs.hcbbs.com/thread-606822-1-1.html
Article 5.2.28 of the Code for Fire Protection Design of Petrochemical Enterprises GB 50160-2008: Around equipment areas where there is a risk of leakage or spillage of flammable liquids during startup, shutdown, or maintenance operations, dikes and diversion facilities with a height of not less than 150 mm shall be installed.
Agree with what was said above; also, the total volume inside the cofferdam should be greater than the volume of the largest equipment located within it. Prevent spills during equipment accidents from spreading beyond the cofferdam.
