Automatic rim seal fire protection system — Bridge & Roof

Linear heat detection cable at the rim seal, with AFFF or AR-AFFF foam discharged into the seal area. Applied to floating roof storage tanks in crude and naphtha service.

Scope of work

• Design. Tank data, the seal and foam dam arrangement, detection along the rim, and the foam quantity the code requires.
• Supply. Linear heat detection, foam pourers, the foam supply and the release equipment.
• Installation on the tank. Detection laid in the rim space and pourers on the shell, planned around the tank’s operation and its hot-work permits.
• Testing. Detection loop tests and a pressure test of the foam lines.
• Commissioning. Simulated detection through to release, and a discharge test where the operator permits one.
• Handover. As-built drawings, test records and operating and maintenance manuals, with training for the people who will run the system.
