SGS Risk Analysis at Offshore Platforms in Mexico
On December 27, 2013, Pemex Offshore Production and Exploration assigned SGS to provide risk analysis and reliability study services for the interconnection of the well emergency valves and pipelines emergency shutdown (ESD) systems at two satellite production platforms, scheduled from January to May 2014.
SGS has been offering various services to the Pemex offshore industry over the years, ranging from detailed risk analysis, technical expertise, as-built studies, project management for investment projects, technical administrative audits to technical assistance during shutdowns, environmental and safety audits, jack-up and structural inspections.
Pemex, Mexico's state oil company, is engaged in the exploration, production, transportation, refining, storage and sale of hydrocarbons and derivatives. Its products include petrochemicals, natural gas, liquid gas, sulphur, gasoline, kerosene and diesel. Pemex operates 344 production fields, 6,382 production wells, 225 off-shore platforms, 6 refineries, 8 petrochemical complexes, 7,896 km of gas pipeline, 4,548 km of oil pipeline, and 19 LPG distribution terminals.
The Mexican Offshore Project
Representatives of Pemex met with SGS project leaders to discuss an insurance company request that the emergency shutdown (ESD) systems of all wells operated in the RMSO region need to be directly connected to the emergency shutdown valves of the production platforms in accordance with the recommended practice API 14C.
Pemex top management of this region requested SGS to prepare a detailed risk analysis in order to review the operability and reliability of the proposed interconnection system, comparing it with the existing system. SGS will conduct a HazOp study to define any operational risks with the determination of risk scenarios, in which the relevant valves would be or not be activated, and prepare a comprehensive analysis of the consequences of those scenarios using the Phast software. Further reliability studies will be done on the interconnected systems using the fault tree analysis methodology. Based upon this analysis, SGS experts will determine whether valves should be connected or not, and if so, operational procedures establishing closure times, activation conditions and other provisions will be developed.
In Mexico, on-site SGS personnel will include 7 experts, experienced in quantitative risk analysis, accident consequence analysis, hazard and operability (HazOp) studies, and functional safety.
These specialists will begin by reviewing 2 satellite platforms to assess actual operational and emergency conditions and procedures, conduct physical inspection of installations and verify that DTI plans received are up to date. SGS will provide a HazOp coordinator and administrative support to prepare reports on HazOp sessions. Other members working within the multidisciplinary HazOp group include Pemex engineers specializing in instrumentation and control, process engineering for the selected satellite platforms, electrical engineering and HSE as well as an engineer responsible for the execution of this project.
Secondly, identified risks will be classified according to the risk matrix of the Pemex procedure and subsequently-developed risk scenarios will be analyzed with the Phast software. Consequence analysis based on considered risk scenarios will be performed using Phast software and the potential impacts of these consequences will be measured and evaluated.
Finally, SGS will conduct reliability calculation with the help of ExSilentia software in order to evaluate the failure probability and system operation ability. Proposal regarding the system interconnection architecture and elaboration on the cause and effect matrix will be provided.
These important SGS services will reduce risk, improve safety and protect investments relevant to the Mexican offshore production platforms.
SGS Risk Assessment and Management
To ensure success, effective risk management is vital during every phase of every project. SGS offers a comprehensive range of risk management and assessment services which take a structured approach to managing risk at every project stage.
From initial construction to on-going operation and maintenance of assets, SGS identifies, assesses and manages risks associated with the cost, performance, safety and scheduling of each individual project. SGS guarantees its services exceed national compliance standards of countries in which projects are executed or assets are operated.
Over 50 years of extensive experience in providing comprehensive testing, analysis and risk management processes, SGS services increase productivity, improve safety standards, protect investment and add value to assets.
SGS is proud to be a part of this prestigious and important project ensuring the safe and reliable operation of these offshore platforms and protecting the environment and the citizens of Mexico.
