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.

Subsea Controls & Instrumentation Engineering

• Develop and review specifications for topside subsea control system (i.e. HPU, TUTU, EJB, EPU, MCS), subsea control system (i.e SCM, Flying leads, Actuated valves, Electrical and Hydaulic Flying leads) and related 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 subsea electrical/hydraulic control circuits related to controls and instrumentation including Umbilical and Subsea Control system network.

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).
