AI Technical Summary
In the existing technology, when the exhaust pipe of the floating production storage and unloading unit passes through the fireproof bulkhead, the high temperature heat is easily transferred to the bulkhead, resulting in potential safety hazards and failing to meet fire protection requirements.
The design incorporates a combination of exhaust pipe flange, through-cabin flange, base, heat insulation pad, and fireproof insulation, which are secured with bolts and nuts. The heat insulation pad is installed between the through-cabin flange and the base, and fireproof insulation is installed between the base and the bulkhead to ensure that heat is not transferred to the bulkhead.
It effectively prevents the high-temperature heat from the exhaust pipe from being transferred to the structural bulkhead through the penetration parts, meets the A60 fire protection requirements, and reduces safety hazards.
