Oil & Gas Control and Safety Systems

TDL delivers control system upgrades, integrated control and safety systems (ICSS) and hazardous-area control panels for oil and gas facilities. Project references cover a gas processing plant, a gas distribution station, a refinery, offshore platforms and an LNG export terminal.

What TDL delivers

• Integrated Control & Safety Systems (ICSS)

  ICSS for onshore and offshore oil & gas facilities and petrochemical plants. Process control on redundant ControlLogix with 1715 redundant I/O, PlantPAx and AVEVA. Safety instrumented systems for SIL 2 and SIL 3 functions on AADvance and Trusted, including ESD and Fire & Gas; safety PLC applications on GuardLogix. Cause & effect implementation and witnessed testing.

• PLC & Control System Migration

  Allen-Bradley PLC-5, SLC 500 and MicroLogix, Siemens S5 and HIMA systems upgraded to ControlLogix and CompactLogix; ControlNet and DeviceNet to EtherNet/IP; older HMI/SCADA (RSView32, Citect, PanelView) to FactoryTalk View and PanelView Plus 7. Drive upgrades: DC drives to PowerFlex, legacy servo drives to Kinetix. Site survey, code conversion, FAT/SAT and planned cut-over, onshore and on offshore platforms.

• Industrial Networks & OT Security

  EtherNet/IP networks on Stratix managed switches, with redundancy by DLR rings, PRP and HSR. VLAN segmentation, firewalls and secure remote access following IEC 62443 zone and conduit principles. Interfaces to third-party systems over Modbus and OPC UA.

• Control Panel Engineering

  Control and marshalling panels: design, schematics, fabrication, wiring and factory acceptance testing before shipment. Ex-rated enclosures for hazardous areas.
