Subsea Controls Engineer (Shallow Water Pipeline Project)

Key Responsibilities

Subsea Controls & Instrumentation Engineering

• Develop and review technical specifications for subsea instrumentation (pressure, temperature, flow, valve sensors).
• Review and validate instrument data sheets, wiring diagrams, I/O lists, and loop sheets.
• Ensure instrumentation correctly integrates with Subsea Control Modules (SCMs) and Master Control System (MCS).
• Oversee the design of electrical/hydraulic circuits within umbilicals related to subsea controls.

Control System Design & Functional Logic

• Develop control narratives, functional logic diagrams, and cause-and-effect (C&E) matrices.
• Verify communication protocols including Modbus, CANbus, Ethernet, and fiber-optic systems.
• Ensure all design activities comply with API 17F, API 17O, ISO 13628-6 and project standards.

Operational Philosophy Implementation

• Translate the project operational philosophy into implementable control strategies.
• Develop and validate control modes (automatic, manual, remote, local).
• Establish safe and maintainable operating sequences for startup, shutdown, ESD, pigging, and chemical injection.

Interface & Integration Engineering

• Coordinate technical interfaces with pipeline engineering, umbilical/FOC teams, subsea vendors, and topside ICSS teams.
• Maintain and monitor interface registers and ensure timely closure of interface actions.
• Ensure system alignment prior to FAT, EFAT, and SIT.

Testing, FAT/SIT & Commissioning

• Prepare, review, and approve FAT, EFAT, SIT, and commissioning procedures.
• Witness SCM, MCS, and instrumentation testing, including calibration and loop checks.
• Support offshore commissioning, energization, and functional validation of subsea controls.

Operational Assurance & Troubleshooting

• Provide onshore and offshore technical support during operations.
• Analyze diagnostic data, condition monitoring outputs, and fault indications.
• Investigate and resolve instrumentation or control logic anomalies.

Key Competencies

• Strong knowledge of subsea instrumentation and control hardware.
• Expertise in SCM, MCS, HPU systems, CI lines, and subsea ESD logic.
• Experienced in reading and preparing P&IDs, I/O lists, and logic diagrams.
• Ability to convert operational philosophy into robust control strategies.
• Offshore SIT/commissioning experience (preferred).
• Strong troubleshooting and analytical skills.

Minimum Qualifications

• Bachelor’s Degree (BSc) in Engineering from an accredited university.
• Minimum 12 years of relevant engineering experience after graduation.
• Excellent spoken and written English, with proven ability to prepare specifications and technical reports.
