【Abstract】 The dissertation focuses on deepwater rigs system design for ultra-deepwater semi-submersible platforms/unites (SSDP/SSDU), which is a part of the“863”High Technology Research and Development Program of China (No.2006AA09A104)—the key technique research on SSDPs’design and construction. Aiming at improving the operation efficiency of deepwater drilling, the paper synthetically adopts theoretical research, numerical calculation and computer simulation and perfects well drilling technology, drilling system mode option and layout optimization based on application and processing external marine drilling rig and SSDP. The main achievements are summarized as follows:1. Research on critical path optimization of deepwater drilling processNot only does dual derrick rigs lead to profound revolution of well drilling technology, but also cause significant change on drilling rigs configuration. The theory of concurrent engineering and Gantt chart are applied to analyze mechanism of dual derrick rigs process flow which lies in two factors—concurrent operation and cooperative operation. Concurrent operation breaks through sequence operation and cooperative operation completes work by main and auxiliary rigs together. Drilling craft of exploration well and development well are made out and optimized by Gantt chart. The well drilling process shorten well construction period and improves benefit. At last, prime equipments supported dual derrick rigs are established which are base for subsequent work.2. Research on rigs system mode option and configuration optimizationAs driliing operation efficiency is determined by the drilling rigs system, selection and configuration of deepwater rigs system is key of the construction of 6th generation domestic SSDP. Based on theory of decomposition-coordination for complex large-scale system, deepwater drilling rigs system is divied into 5 sub-systems, including of rigs, material transportation system, power system, logistics service system and control system. Function relation of sub-systems and optimization model is set up and two sub-systems—rigs and drilling material transportation system are studied especially. The relation between offline operation ability and rigs configuration is studied that the the more offline equipments, the more work efficient. Two kinds of rigs—offline rigs and dual derrick rigs are compared by payback period and net present value (NPV) from viewpoint of efficiency, variable derrick load, patent and cost of construction. And result shows that the dual derrick rigs is more excellent as a whole. Transportation modes are determined by shape and quality of material modality, and they are divided into three modes—drilling pipes, large special equipment and drilling mud system, and optimized the process flow and equipment configuration. The paper analyses two risers storage models and equipment configuration, and compares to occupying deck area, center of gravity general layout and operation efficiency. The result shows that there is no evidence difference in center of gravity and system operation efficiency besides they have significant effect in general layout. Risers’operation efficiency factors are analyzed and measures to improve efficiency are put forward, of which risers’connector should be attached importance to. SSDP & drilling equipment management information system is set up for the sake of improving management and benefit of equipment option.3. Study on layout optimization of rigs systemRigs system layout integrates the characteristic of production system and complex three-dimensional (3-D) system layout. The dissertation firstly brings forward compound /integrated hierarchical division based on process flow and constitutes layout theory, arithmetic and layout process on the basis of complex large-scale composition- coordination. The method is based on operational flow and different transportation modes are marked out according to the shape and quality to material modality. Two hierarchy decompose—sub-space and modules,which are basic layout units,are brought into operation. We applied different layout arithmetic to mark out the upper and lower decks. That is, the upper deck was designed based on the lowest transportation cost while the lower deck’s calculations were based on the best-fit scope. Finally the center of gravity was taken into consideration and the general layout was adjusted according to result in an optimal center of gravity. The project strongpoint doesn’t only lies in taking into account efficiency, safety, stability and human factors engineer, but also engineer practicality and optimization, especially in 3-D layout with behavioral constraints. According to the layout programming, we take the 863 project in the scantling design as an example, implementing the layout of rigs system in details. In order to validate layout for further, 3-D modeling of SSDP and rigs system are constructed to carry into execution simulation of assembly and process flow moving.4. Research on drill fllor layout optimization and driller cabin design based on human factors engineer.Drill floor of semi-submersible drilling platform is the work center of drilling. And there are three different operation flows handled with drill pipes, large-diameter casings and risers. The driller layout principle and program are made certain based on process, linking up and manipulation relation and human factors engineer. All automated equipments on drill floor are collocated with layout principle and program and assorted with tubulars’transportation, temporary storage and handling. The main and auxiliary drilling centers are adopted 1:3—proportion off-center arrangement which is according to result of numerical calculation and ABAQUS simulation.As driller cabin is the core control component of rigs system, and the target platforms equipments is so automatic that driller cabin traditional design can not meet with the trend. The human factors engineer is used to design the driller cabin. The paper applies ergonomic principles to design driller cabin and achieve mechanism of communication harmony and information overload and colony harmony. Third class control pattern are used in the course of collectivity design, that is: LCD—type of show, touch screen—type of main control, multifunctional chair—traditional type of manual control, which can carry out unify between process-based control to manual operation to change past equipment function-based integration. The new idea and technique presented in the paper can improve the design of the driller cabin.更多还原
