Objectif The aim of the PLATINE project is to specify a central production platform, unmanned,teleoperated from a control room located onshore, with a yearly (or half-yearly) visit for inspection and overhauling.The intermediate aims consist of working out and testing pilot units related to sub-systems and testing new equipments.The project has been divided into 4 phases : PLATINE - Phase 1 ( 1986-1988); PLATINE - Phase 2 (1987-1989); PLATINE - Phase 3 (1988 -1990). 89); PLATINE - Phase 4 (1989-1991).Two modules are being studied : gas-lift and sea water injection. For the other modules, investigations have been made and future works guided.- Gas-lift : A prototype 2-phase flowmeter has been built and tested; after modification results appeared not acceptable and this application has been cancelled.The automatic start-up has been defined with unique injection point. The gas-lift optimization will be carried out in testing the wells only when well behaviour has changed. Monitoring will be through a permanent bottomhole pressure sensor or, in a degraded mode, by permanent knowledge of wellhead temperature and/or wellhead casing pressure.- Well pumping : Various means of well pumping have been evaluated resulting in the selection of the long-stroke pumping set.- Sea water injection : The principles have been assessed and processes have been selected : filtration, deoxygenation, chloration and bacterial treatment. Reliable and accurate enough control analysers have been searched for (filtration quality, bacteria content, 02, Cl2 content. . . ).- Rotating machines : A comprehensive investigation has been made into (NEACP) subsidiaries, oil companies and other industries. This high-lighted that a lot of existing equipment or facilities have failure rates unacceptable to PLATINE.Further, the development of new technologies by manufacturers has been followed and guided (peripheral/centrifugal compressors, magnetic bearings, gas packings and variable speed engines).- Maintenance : A list of curative or preventive works and trouble shooting on existing platforms has been drawn up. Optimal electric scheme has been studied (comparing for example offshore generation to onshore generation with cable transportation).A condition-based maintenance program has been carried out.It is the basis for an expert system applied to turbines and compressors but applicable to any kind of rotating machine.An on-line event generator has been worked out; it consists of a common kernel and a specific module dedicated to electro-compressors. An off-line expert system for compressor maintenance (fault diagnosis) has been developed.- Sensors : a large number of process sensors (gas and liquid flowmeters, level sensors, BSW meters) and pressure and temperature bottomhole sensors have been selected and purchased; sensors have been tested; the results have lead to the definition of modifications to be applied to these sensors in order to meet the PLATINE requirements.- Miscellaneous : A preliminary study of the application of a surveillance robot has been made.This project consists of several items :- methodology studies;- test and adaptation of equipment;- development or adaptation of maintenance and production softwares.The adopted policy will aim at simplifying the general architecture and examining the existing processes or methods critically. Use of new techniques or materials will be systematically assessed.The facilities have been divided into 7 main sub-systems : 4 production sub-systems (gas-lift, sea water injection, separation -treatment, well pumping) and 3 sub-systems non specific to oil industry (energy/rotating machinery-safety/reliability-automation sytem).- The gas-lift-sub-system study has 3 parts : conception and construction of a 2-phase flowmeter - automatic start-up of a well in high pressure gas-lift - real time optimization of gas-lift injection.- The sea water injection sub-system study aims at selecting sea water treatment processes before injection and at specifing the best means of lifting and pumping.- The separation-treatment sub-system study aims at specifing a separation-treatment chain compact, optimal and adapted to the project.- A study related to the various means of well pumping will enable us to select the (or the two) best means and to specify the automation works to be done.- An on-condition plan will be worked out ; the main lines of the future on-condition system (including probably an expert system) will be defined.- A comprehensive statistical investigation of rotating machines will be carried out. Besides, the development of new technologies in this field will be followed and directed in connection with the manufacturers ; the main planned actions are related to peripheral /centrifugal compressors, variable speed engines, magnetic bearings, and gas packing.- The automation system includes sensors, making their measurements reliable, communication system and expert systems. The reliability of an automation system is mainly dependent on the reliability of sensors. The actual sensors will be tested then adapted, if needed for offshore oil conditions; their measurements will be made reliable by means of coherence treating numerical system. Prototype systems of optic fiber transmission will be tested; the development of optic sensors by manufacturers will be followed and guided.- The safety/reliability module includes regulation studies, reliability studies related to equipment or systems safety equipment and platform surveillance (with possibly a future robot development).
