The primary objective of this study was to assess the hazards and impacts of the proposed project in terms of risk on Health, Safety, Environment and the company’s reputation
Ras Laffan Port Expansion Project was initiated in 2002 to support the production increase of the North Field Gas reserves, estimated at 248MTpa, up-to 2024. The port expansion project included the development of breakwaters, five LNG Berths, additional eighteen Liquid Product Berths, including LPB 30 and 31, five Container Berths and associated common infrastructure, utilities and services. However, during the execution, scope of LPB 31 was deleted from scope.
With increase in production of Liquid Products, along with the 43% increase in LNG production from the NFE Project, facilities at LPB 31 are required to be completed to support logistical operations. The berth infrastructure, quay walls, loading platforms, metering platforms, breasting dolphins, mooring dolphins, fenders, walkways, utility lines roads have been installed.
Also, the existing oil spill boom barrier provided at the mouth of the common seawater facilities intake, is not fit for purpose. The system is currently inadequate to fully contain any potential accidental chemical contaminants entering the intake system. Therefore, a new boom barrier is proposed around across the full length of the sea intake breakwaters. The new system shall ensure that no accidental contaminants can ingress to the cooling water intake facilities and shall withstand the environmental conditions of the site.
The scope of the Project includes two distinct parts:
Part 1: Liquid Product Facilities
The Hazard Identification (HAZID) workshop conducted at Ras Laffan Industrial City (RLIC) aimed to assess the hazards and impacts of the proposed project on health, safety, the environment, and the company’s reputation. The Ras Laffan Port Expansion Project, initiated in 2002, supports the production increase of North Field Gas reserves up to 2024.
The project entails two distinct parts. Part 1 involves the engineering, procurement, installation, testing, and commissioning of facilities for LPB 31, including an oil spill containment equipment package, marine access gangway, marine monitoring system, ship-to-shore link system, extension of firewater and foam networks, terminal firefighting equipment, safety shower, eye wash equipment, and various safety features.
Part 2: Oil Spill Boom Barrier for CSF Intake
Part 2 focuses on the engineering, procurement, and installation of an oil spill boom system for the Common Seawater Facility (CSF) intake, with subsequent disassembly of the existing system.
The existing oil spill boom barrier at the CSF intake is deemed inadequate, necessitating a comprehensive replacement to prevent accidental chemical contaminants from entering the intake system. The proposed system is designed to withstand environmental conditions at the site, ensuring effective containment and protection of the cooling water intake facilities.
The HAZID workshop, conducted in adherence to Qatar Energy Corporate Standards and Guidelines, systematically identified potential Safety, Environmental, and Health hazards associated with the project. The report outlines findings and recommendations, addressing critical aspects such as oil spill containment, marine access, monitoring systems, firefighting facilities, safety equipment, and environmental protection measures. The workshop’s thorough examination provides a foundation for effective risk management throughout the engineering, procurement, installation, and commissioning phases of the EPIC Project. The document reflects a commitment to corporate standards, safety, and environmental responsibility in alignment with the goals of Ras Laffan Port Expansion and Qatar Energy’s guidelines.
