Description:
We are looking for a DCS Technician to join our client’s team. If you are looking for a way to accelerate your career and be part of an industry-leading company, this may be the opportunity for you! Out client operates oil refineries, chemical plants, and biofuels facilities across North America and is part of a global leader in several industrial markets.
The primary DCS technology at Corpus Christi refinery is Emerson DeltaV. We interface the DeltaV with Allen-Bradly and Triconex PLCs, and our plant uses HART device alerts from DeltaV in our AMS system.
What You Will Do
- Assist instrument and analyzer techs and electricians with troubleshooting unexpected data to or from or within the DCS.
- Collaborate with DCS console operators to make operability improvements, including DCS graphics modification and alarm management and rationalization.
- Collaborate with process control engineers in the development, implementation, and improvement of DCS-based advanced control strategies, including state-based control, transition automation, and model predictive control; implement configuration for supervisory controls capabilities.
- Collaborate with project engineers to guide project scopes that economically meet expected business outcomes.
- Collaborate with project designers, from reserving system IO and performing field walk-downs to providing the guidance necessary for their development of complete and error-free IFC project design packages.
- Implement DCS vendor hot-fixes and security updates; upgrade DCS system hardware and software without interrupting the process.
- Proactively frame-up and recommend improvements to DCS installed equipment to meet potential future needs of customers and users.
- Collaborate with instrument techs and DCS console operators in the commissioning of new or modified DCS configuration and enabling HART communications for smart field devices.
- Collaborate with peers at other FHR sites, sharing what you know and learning from them.
