Qatar Petroleum has awarded the EPC contract for upgrading and replacement of Fire protection system at Berth 6 in Mesaieed port.Berth 6 facilities including fire protection systems were constructed to cater import and export operations of bulk raw and refined hydrocarbon products such as Gasoline, Jet Fuel, Gas Oil and Decant Oil. As such, reliable operability of the Fire Protection System is provided in a state of continuous readiness to ensure adequate fire protection on continuous basis.
The berth 6 was commissioned by QP Refinery in 1988 to serve importing & exporting of finished Petroleum products. The loading/unloading area comprises of 5 ship loading/unloading arms with pipelines from berth to refinery. The berth facility includes Operations control room, Pig launching/receiving areas, substations, and Fire protection facilities.
As a result of an extended period of service and various mechanical defects due to ageing and severe corrosive environment, the fire protection system reliability has been significantly degraded leading to frequent breakdown of various critical components of the system for prolonged periods.
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 Foam Proportioning System.
