<strong>REAL</strong> <strong>RESULTS</strong><strong>PLC</strong>-<strong>Based</strong> <strong>Offshore</strong> <strong>Platform</strong><strong>Control</strong> <strong>System</strong> Provides TurnkeyMonitoring, <strong>Control</strong> and Well TestingObjectives• Monitor, control, and test oil wells on two offshore platforms.• Choose a system that can accommodate future expansion.Results• Weatherford developed two platform control systems, eachconsisting of a 16-well wellhead control panel, a well test panel,field interface panels, a safety-system hot-backup programmablelogic controller (<strong>PLC</strong>), a process-system hot-backup <strong>PLC</strong>, and hotbackuphost computers.• Twelve well-control modules were installed.• A total of 19 field interface panels were installed and included bothpneumatic and electronic controls.• Weatherford mounted and wired the hot-backup <strong>PLC</strong>s, light-boxannunciators, and power supplies in freestanding, paintedNEMA 4 enclosures. The <strong>PLC</strong> relay-ladder logic programmingwas conducted in-house by Weatherford engineers.• Weatherford provided project management and engineering,programming, configuration, packaging, factory acceptancetesting, system documentation, training, and installationassistance for a complete solution.Weatherford’s multi-well panels are planned andmanufactured in-house to client-definedspecifications, using the very latest designtechnologies and components,LocationAngolaWell Type<strong>Offshore</strong> oil platformsProducts/Services<strong>Control</strong> systemValue to Client• The 16-well wellhead control panel was chosen based on itsmodular design, which would allow the client maximum flexibilityfor future upgrades, reduce up-front capital expenditure at projectinception, and allow system expansion for future fielddevelopments.• The field interface panels provided the client with local control ofskid-mounted equipment, manual-process bypass control,process indicator lights, and marshalling racks.WeatherfordKevin SnowlingSubsea Program Managerkevin.snowling@eu.weatherford.comweatherford.comWeatherford products and services are subject to the Company's standard terms and conditions, available on requestor at weatherford.com.
