Process Control Technologist

Aster Chemicals and Energy is a leading provider of chemical and energy solutions in Singapore and in the Asia region. Building on the foundations of Singapore’s first oil refinery, Aster has a fully integrated refinery and petrochemical manufacturing operation on Pulau Bukom, and downstream chemical assets on Jurong Island.

Purpose:

The process control technologist role is to be responsible for delivering the control and safety systems upgrading projects with respect to alarm management, base layer control, safeguarding logic design and commissioning and implementation is done in accordance to the standards and best practices. He/she is required to provide the related training to operators.

Accountabilities:

1. Provides review and input into contractor deliverables such as functional specifications, technical queries and deviation requests from the contractor and management of change requests.
2. Provide QC/QA process control deliverables and contribute to other technical deliverables when required.
3. Interface with Project and Engineering department to co-ordinate and plan the resources required to support the delivery of projects with scope for alarm management, process control and safeguarding.
4. Coordinate the interfaces with other disciplines on the project and coordinate engineering support from contractor or Main Automation Contractor (MAC) if required.
5. Support major activities like Factory Acceptance Test or Site Acceptance Test (FAT/SAT) for Distributed Control System (DCS) and Safety Instrumented System (SIS) changes to provide assurance for process monitoring, alarm management solutions, control and safeguarding functionality.
6. Contribute to knowledge retention by delivering documents such as process control and safeguarding narratives, inclusive of Cause and Effect diagrams and consolidations of lessons learnt.
7. Document and update a standard engineering practice to ensure consistent and standardized implementation across the entire site.
8. Participate in major activities like factory acceptance and site acceptance tests for DCS, Oil Movement System (OMS) and SIS and unit startup support.
9. Identify opportunities for improvements in control strategy and control configuration.
10. Improve robustness of Base Layer control performance, delivery of high uptime and low operator intervention rates.
11. Maximize benefits from optimization applications through the implementation of unit wide Advanced Process Control (APC) and Real Time Optimization (including Advanced Analytics) systems.
12. Support the design and implementation of Advanced Process Control applications to maximize benefits and save energy.
13. Support Production team activities for e.g. alarm management and ensure plan delivery.
14. Participate in design or safety review and provide process control and safeguarding related inputs to projects.
15. Contribute to multifunctional teams in site wide initiatives, such as unit shutdown/startup preparation and coordination.
16. Demonstrate strong learner mindset and commits to be digitally literate to drive value creation through digitalisation.
