Instrumentation & Controls Engineer
Sugar Land, Texas
Instrumentation & Controls Engineer
The I&C Engineer provides day-to-day instrumentation and controls technology support to Operations and Maintenance. Additionally, the I&C Engineer has responsibility for stewarding instrumentation technology to support reliable measurement and final control instrumentation to meet the refinery’ s safety and profitability objectives. Working closely with Tech Services, Project and Process Control Engineers, the I&C Engineer selects and designs instrumentation to meet measurement and control objectives.
- Thorough understanding of basic four process measurements (i.e. flow, level, pressure and temperature). I&C Engineer will be required to understand the requirements for custody metering and unit material balance. The I&C Engineer will have a good understanding of the limitations of instrumentation, matching to the application and measurement error propagation.
- Engineering and maintenance of instrumentation to support data collection and control. The I&C Engineer must demonstrate the ability to define the requirements of Projects, Tech Services and Process Control Engineers, and to design, select and deploy solutions that meet the requirements.
- Steward critical flow meter calculations, instrumentation and installations to ensure products and streams are measured within tolerances.
- Lead and steward equipment strategies to support Preventive and Predictive Maintenance Strategies using manual and on-line monitoring systems (i.e. Asset Management System – Device Manager). Develop surveillance strategies and monitor critical equipment performance including control valves.
- Lead, manage and steward instrumentation best practices through the Accepted Manufacturers List, technical and installation practices and failure investigations.
- • Provide consulting to management of long term, strategic directions for instrumentation. Develop or support the development of AFE’ s and budget items for all instrumentation applications.
- Actively and effectively mentor junior members, new employees, non-instrumentation personnel and instrumentation tech to better understand instrumentation, requirements for design/specification, technology limitations based on the physical properties of the fluid being measured, and measurement error.
- Lead, develop and conduct testing on emergency shutdown systems. The I&C Engineer requires a strong understanding of IEC 61511 or ANSI/ISA 84, the Safety Requirements Specification and SIL/SIF calculations.
- Ability to conduct step testing, dynamic analysis and tuning of regulatory controllers.
- 9-15 years of experience in a refinery or chemical company instrumentation department, preferably with experience in day-to-day support to Operations and Maintenance
- Experience in using instrumentation standards based on ISA standards such as 5.1, 20 and 75
- Technical knowledge of instrumentation signal basics – 4-20 mA, HART, Modbus
- Willingness to conduct field walkdowns and interface with filed maintenance personnel
- Ability to work with standard I&C documentation – P&IDs, loop drawings, C&Es, Binary Logic Drawings, Ladder Logic Drawings, Schematics and ISA S-20 Datasheets
- Expert knowledge of flow measurement fundamentals
- Advanced Microsoft Analytics Skills
- Bachelor’ s Degree in Electrical or Chemical Engineering required
- Strong understanding of field instrumentation fundamentals (i.e. flow, pressure, temperature and level), advanced instrumentation technology (i.e. process, fire and gas analyzers and safety shutdown systems)
- Professional Engineering License and Safety Certification are preferred – must be eligible and willing to seek license and certification upon employment
- Accurate and optimized measurement to support effective control or decision making
- Accurate, reliable, instrumentation is required for stable regulatory control – a precursor for the successful application of advanced control technology, Reliable, accurate process correlations can eliminate the purchasing and maintaining of cost on-line analyzers, at a significant cost savings
- Optimum operation of a complex refinery control system with the result being profitable, safe, reliable operations
- Operators are supplied with process information in an easy to read format to enable them to monitor operations or make immediate adjustments
- Reliable, fast, and up-to-date instrumentation provides the Operator, Process Engineers and Management with confidence in the reported and histories data – reduces the requirement for “ best guess” meter factors, “ gut-feel” or opinion
