Working on behalf of OneSubsea (formally Cameron), a Subsea Oil & Gas production equipment manufacturer in Houston Texas, developing Subsea PLC based MCS (Master Control Station) equipment to monitor and control subsea production wells and manifolds.
Projects included Kizomba B for Exxon Mobil in Angola, Captain for Chevron in the North Sea and Ceiba for Hess in Equatorial Guinea.
Deliverables included SDS, FDS, FAT and IOM document development, equipment protection interlocking, shutdown sequencing, simulation and Modbus/OPC based interfaces to DeltaV and Honeywell DCS production control systems on the customer FPSOs, platforms or onshore production facilities. Programmed redundant GE Fanuc 90-70 PLCs which interfaced with subsea via onboard VME computers running a propriety protocol. Interfaced with topside Siemens S7 PLC based skid units via SST Profibus VME interface cards. Developed the redundant server based Cimplicity HMI with redundant Ethernet cabling.
Also developed various Linux based MCS projects for their facility in Celle Germany, which is OneSubsea’s main offering today.
