Qatar Petroleum awarded an EPC contract for upgrading and replacing the fire protection system at Berth 6, Mesaieed Industrial City (MIC) Port. This berth handles import/export operations of refined hydrocarbon products, such as gasoline, jet fuel, gas oil, and decant oil, requiring continuous fire protection to ensure safe operations.
Background
The berth 6 was commissioned by QP Refinery in 1988 to serve the importing and exporting of finished petroleum products. The loading/unloading area comprises five ship loading/unloading arms with pipelines from berth to refinery. The berth facility includes an operations control room, pig launching and receiving areas, substations, and fire protection facilities.
As a result of an extended period of service and various mechanical defects due to aging and a severe corrosive environment, the fire protection system's reliability has been significantly degraded, leading to frequent breakdowns of various critical components of the system for prolonged periods.
Project Objective
QP thereby intends to upgrade and replace the existing fire protection system with the latest compliant system and ensure business continuity. Our scope includes a detailed Engineering Design for a foam proportioning system.
