Umbilical & Fiber Optic Cable (FOC) Engineer Offshore Shallow-Water Subsea Pipeline Project

The Umbilical & FOC Engineer is responsible for the design, specification, manufacturing follow-up, installation engineering, and operational readiness of subsea umbilicals and fiber optic cables used in shallow-water pipeline projects. This role ensures all electrical, hydraulic, chemical injection, and fiber-optic systems meet project requirements and interface seamlessly with subsea and topside systems.

Key Responsibilities

Engineering Design & Technical Coordination

• Develop design basis and specifications for subsea umbilicals, hydraulic/chemical lines, electrical cables, and fiber optics.
• Review umbilical cross-section design, electrical loading, tube sizing, and fiber-optic transmission performance.
• Ensure compliance with API 17E/F, ISO 13628, and DNV standards.
• Review cable data sheets, P&IDs, electrical schematics, and fatigue analyses.

Manufacturing & Factory Surveillance

• Follow up vendor processes for tube welding, fiber-optic integration, and conductor manufacturing.
• Review FAT/EFAT procedures including OTDR tests, pressure testing, continuity, and insulation resistance tests.
• Ensure vendor compliance with ITPs, quality plans, and manufacturing procedures.

Installation Engineering Support

• Review umbilical installation analyses including tension, bend radius control, and touch-down behavior.
• Review pull-in procedures (J-tube, I-tube, direct pull-in).
• Support load-out, spooling, offshore lay, termination, and testing activities.

Interface Management

• Interface with subsea controls for SCM power, signals, hydraulic capacities, and channel allocation.
• Interface with subsea structures for routing, supports, BU/BS selection, and tie-in frames.
• Interface with topsides for MCS/ICSS connectivity, hang-off, power, and communication.
• Interface with installation contractors for MBR limits, tension, and ROV operations.
• Interface with geotechnical and survey teams for seabed preparation, burial needs, and route optimization.

Testing, Commissioning & Handover

• Prepare commissioning procedures for hydraulic flushing, electrical checks, and fiber-optic communication tests.
• Support offshore OTDR tests, pressure testing, leak checks, and system energization.
• Ensure all as-built records and QA documentation are completed.

Technical Requirements

• Expertise in subsea umbilical and fiber-optic cable engineering.
• Strong understanding of LV electrical systems, fiber-optic communication, and hydraulic/chemical injection lines.
• Skilled in OTDR analysis, electrical load calculations, and umbilical routing/design tools.
• Knowledge of API 17E/F, ISO 13628, and DNV-RP-F401 standards.

Required Qualifications

• Bachelor’s degree in Electrical, Mechanical, Subsea, or Telecommunications Engineering.
• Master’s degree in Offshore/Subsea Engineering (preferred).
• 8-10 years of experience in umbilical/FOC engineering for offshore projects.
• Experience with vendor follow-up, FAT/EFAT, and offshore installation.
• Strong communication, coordination, and documentation skills.
