The Subsea Controls Engineer is responsible for the engineering, integration, verification, and operational readiness of subsea control systems supporting shallow-water subsea pipelines, manifolds, valves, and associated structures. The role focuses on instrumentation, system logic, interface engineering, and implementation of the field operational philosophy.

General Description of Role and Responsibilities:

Subsea Controls & Instrumentation Engineering

• Develop and review specifications for subsea instrumentation (pressure, temperature, flowmeters, valve sensors).
• Review instrument data sheets, wiring diagrams, I/O lists, loop sheets.
• Ensure proper integration of instrumentation with SCMs and MCS.
• Oversee design of umbilical electrical/hydraulic control circuits related to controls and instrumentation.

Control System Design & Functional Logic

• Define control narratives, functional logic diagrams, and cause-and-effect matrices.
• Verify communication protocols (Modbus, CANbus, Ethernet, fiber optics).
• Ensure compliance with API 17F, API 17O, ISO 13628-6.

Implementation of Operational Philosophy

• Translate operation philosophy into control strategies (startup/shutdown, ESD logic, pigging, CI control).
• Design control modes (auto, manual, remote, local).
• Ensure procedures support safe operability and maintainability.

Interface & Integration Engineering

• Coordinate with pipeline, umbilical, topside ICSS, and vendor teams.
• Manage technical interface registers.
• Ensure alignment of controls and instrumentation before FAT/SIT.

Testing, FAT/SIT & Commissioning

• Prepare and review FAT, EFAT, SIT, commissioning procedures.
• Witness SCM, MCS, instrumentation calibration, and loop testing.
• Support offshore commissioning and system energization.

Operational Assurance & Troubleshooting

• Support onshore/offshore operations.
• Review instrumentation diagnostics and condition monitoring data.
• Troubleshoot instrument and control logic issues.

Key Competencies

• Strong subsea instrumentation knowledge.
• Expertise in SCM, MCS, HPU, CI lines, and ESD logic.
• Ability to translate operational philosophy into field-ready controls.
• Skilled in P&IDs, I/O lists, C&E charts, logic diagrams.
• Offshore commissioning and SIT experience (preferred).

Qualifications, Experience, Knowledge and Skills:

• Bachelor Degree [BSc] from an accredited university.
• Work experience of eight (12) years after earning degree in same field .
• Excellent spoken and written English including proven ability to write reports.
