SIS PLC Specialist

The Safety Instrumented Systems (SIS) and Programmable Logic Controller (PLC) Specialist will provide technical support during the conceptual phase and front-end loading design of SIS controls and PLC configuration including, design, programming, documentation, testing, commissioning and sustainability of SIS-PLC systems in alignment with IEC61511 Standards and INEOS Process Safety Management (PSM) principles at O&P facilities.

Additionally, the SIS-PLC Specialist is responsible for the management of the PLC networks, site-wide PLC monitoring system, and supporting hardware and software. The site Cybersecurity related support for PLC network system, monitors and computers, and securities are the responsibility of the SIS-PLC Specialist. Ownership of all PLC backup management and assurance of latest revisions of running PLC programs, validation of system narratives for PLCs and SIS directives/maintenance procedures are

of this position. The SIS-PLC Specialist interfaces with numerous organizations responsible for Operations, SIS and SIF systems, Capital Engineering, Maintenance Capital Projects, PSIM, Reliability and Mechanical Integrity to ensure appropriate alignment in the delivery and sustainability of PLC improvements. This position reports to the E&I Engineering Team Leader.

AND Accountabilities

SIS-PLC Specialist is to support assessment, design, documentation, configuration, testing and commissioning, of new installations as well as maintaining, troubleshooting, optimizing existing systems (hardware & software) at CBW, Stratton Ridge and Hobbs. The

include participating in the Front-End Loading (FEL) design, detailed design, development and Start-Up & Commissioning. Project execution and sustainability support includes the development of documentation to deliver stage reviews and preventive maintenance

to deliver a robust SIS life cycle and optimized PLC system. The role entails understanding and implementing the INEOS 20 Principles and ensuring effective communication of these principles within the work group.

Support and actively participate in the troubleshooting, maintaining and optimization of PLC’s and resolving issues associated with SIS implementation.

Work closely with the site SIS Engineer in improving and maintaining the site’s SIS/SIF systems.

Support documentation of Safety Instrumented Systems (SIS).

Ensure site SIS systems (furnaces, reactors, boilers, compressors, etc.) meet code requirements.

Assess CBW SIS and PLC changes by supporting MOC’s, validating programming changes prior to implementation, supporting training, and verifying all pertinent documentation changes (e.g. procedures, narratives, PM’s) are accurately defined/documented.

Lead, drive and assure that CBW site PLC Systems have up to date narratives, documentation of requested changes, testing and commissioning plans of changes in accordance with Site procedures, PSM and ISA requirements.

Act as Gatekeeper of site PLC systems’ administration and programming while ensuring that the systems are secured.

Support PLC network development.

Support and mentor unit technicians to troubleshoot and development of PLC programming changes, HMI displays and I/O configuration.

Stay abreast of current technology and strive to improve the plant’s General PLC and Safety PLC systems.

Provide support for process related information to the Environmental and Quality Control Department as needed to assure continuity of data used for environmental reporting and quality control purposes.

Review and provide comments on engineering design packages (issued for approval and construction packages) requiring PLC Changes and/or associated to SIS implementation issued by engineering and capital projects teams.

Assist in root cause analysis of process upsets and operation sequence of events.

Develop and configure interfaces to facilitate process improvements and incorporate process, mechanical and safety interlocks.

Support SIS Site Engineer troubleshooting SIS trips, failures to activate, developing/challenging resolutions to activation to prevent re-occurrences.

Support SIS Site Engineer in the Development of Functional Requirements, Specifications, and site procedures/guidelines.

Support SIS Site Steward and SIS Engineering Authority in the effective technology transfer and sharing of SIS and PLC best practices between site teams and INEOS O&P facilities.

Support and actively participate in the troubleshooting, maintaining and optimization of PLC’s and resolving issues associated with SIS implementation.

Provide SIS and PLC guidance in Capital Project development. Support design of SIS and PLC systems in FEL through Detail Design and IFC packages.

Associate degree in Instrument and/or Electrical technology, or professional electrical training degree and SIS/PLC experience acceptable.
