A multiline marine production riser and floating production, storage, and terminal facility may be required for economic development of oil and gas reserves in remote, deep water locations. A deep water production riser design has evolved through study, analyses, and model testing. In order to gain experience, development confidence, and improve the riser design prior to commercial application, a prototype has been built for testing as part of Exxon’s Submerged Production System offshore test in the Gulf of Mexico. This paper treats the design, manufacture, and installation of the prototype multiline marine production riser system.

That the oil and gas exploration and development is extending into deep water proceeds the rapidly shift to subsea production system. However, complex subsea equipment and frequency offshore accidents aroused the concern on the risk assessment of subsea system. The paper illustrates the hazard aspects which should be focused on in the subsea equipment compared with the surface equipment. The hazards identification and risk analysis on subsea X-tree system is carried out. A general risk-prevent process of subsea X-tree system is illustrated, so does the reliability analysis process. Besides, some commendations on subsea detection and maintenance are presented in the paper.

The offshore pilot test of Exxon’s Submerged Production System (SPS) has reached a successful conclusion. This pilot test encompassed the entire spectrum of SPS equipment, spanning from the well completion intervals to, but not including, common surface processing and storage facilities. Since the SPS is designed to meet all the life cycle needs of a subsea field, one of the objectives of the pilot test was to evaluate both the techniques and the equipment used to install, operate, and maintain a prototype version of the SPS. The equipment under test was designed for use in water depths up to 2000 ft, but with minor modifications it is capable of operating in significantly greater depths. Evaluation of pilot test results has shown that the deep water installation techniques are practicable and that the deep water maintenance machinery is competent to repair any failures likely to occur in an operating system. One of the most significant problems in conducting the pilot test was achieving adequate quality control during equipment manufacture. The test results have demonstrated that, with relatively minor modifications, the SPS is suitable for commercial application.

Different equipments combined compose an offshore petroleum production system. Several development alternatives are available for a given offshore petroleum field. The selection of the most suitable system for a given scenario depends on field development characteristics and strategies such as its geographical location, water depth, environmental conditions and knowledge about similar systems already selected and in use for oil and gas production and available infrastructure in around. For the purpose of field production system design a database with types of production platforms, mooring systems, subsea equipments, reservoir main characteristics, type of wells and lifting processes is fundamental. Today, offshore petroleum reservoir production is more and more complex due to several variables involved and requirement needed to meet deep and ultra deep water depth, pre-salt petroleum with aggressive fluid characteristics, fields in remote areas and other environmental issues. Large fields in deep and ultra deep water are particularly challenging due to little availability of suitable platform types, among known concepts such as floating, production, storage and offloading unit (FPSO), semisubmersible, spar and tension leg platform (TLP). In the present paper, a database for worldwide offshore petroleum systems in use has been elaborated by searching data available in the literature. The database is organized for more than three hundred platforms distributed on more than four hundred different offshore oil fields. To serve as a basis for the conceptual design of a field production system, this database contains information such as type of the platform, field location, water depth, days for the first production, type of well, completion, mooring system, riser and offloading system. This information is structured for different water depth and environmental condition, for each field. From this database, analysis has been conducted for distribution of each type of platform by worldwide region, distribution of each type of platform by the offshore field by region, among others analysis. Concept of Utility Functions are applied to represent technological trends and to be helpful in the process. Among the results, a preference for FPSOs and semisubmersible was observed in Brazil offshore, semisubmersible, TLPs and Spars in Gulf of Mexico. In Europe, particularly the North Sea, FPSO, semisubmersible, and few TLPs have been found. In West Africa, most of the field production is based on FPSOs, although some semisubmersible and TLP could be observed. Similar analyses were conducted in other regions. Results and discussions show preferences regarding technology selected by each region, region historical data, and growth of water depth in different fields.

With the development of offshore oil and gas field enters into deep water constantly, subsea production system has become the main development mode in deep water development. Pipeline End Termination (PLET) is common facilities in subsea production system and is used to provide subsea tieback interface. An embedded type PLET has been adopted in Panyu 35-1/35-2 Gas field with the water depth of 194 to 338 m. Factory Accept Test (FAT) is very important for the subsea production facilities, and the references is very limited due to technical security. This paper in detail states the flow chart, master equipment, purpose and precautions for each test of FAT for PLET, which collects great technology for the development of subsea production system.

With the development of offshore oil and gas field enters into deep water constantly, subsea production system has become the main development mode in deep water development. Subsea Inline manifold (ILM) is common facilities in subsea production system and is used to gather oil and gas from the side subsea wells. Two subsea ILMs has been adopted in Panyu 35-1/35-2 Gas field with water depth range from 194 to 338 m in South China Sea. System integration test (SIT) is very important for the subsea production facilities. This paper states the flow chart, master equipment, purpose and precautions for each test of ILM SIT, which collects great technology for the development of subsea production system.

The deep-water pipeline connector (DPC) is a key piece of equipment for the connection of multiple facilities located in different positions of the subsea production system. Its sealing reliability affects the safety of the production system directly during oil and gas exploration. Although the reliability assessment methods of the DPC have been investigated, previous studies have mostly been carried out under a single mechanical field. To determine the DPC reliability considering thermo-mechanical coupling, this paper establishes random load models of working pressure and temperature by using the Gaussian function, and the stochastic finite element model of the DPC is constructed to obtain the sealing performance under coupling conditions. A Kriging–Sobol sensitivity analysis method is developed to obtain the main variables influencing the sealing performance for the purpose of decreasing the computational cost of the ordinary sensitivity analysis. A reliability assessment approach based on the cross entropy-importance sampling-Kriging method is introduced to analyze the DPC reliability, and a sealing reliability assessment method of DPC under thermo-mechanical coupling conditions is finally formed. An engineering case is taken to verify the effectiveness of the proposed method. The results show that the reliability analysis accuracy of the proposed method is almost agreed with the Monte Carlo method, but the computational cost can be reduced 85.61%, which indicates that the proposed method provides designers with a fast method with an acceptable computational cost to assess the reliability of the DPC connector under coupling conditions.
