Role Summary  
The Lead SURF (Subsea Umbilicals, Risers & Flowlines) Engineer is responsible for  providing subsea engineering leadership and technical expertise for the Equinor Titan  Decommissioning Project. This role supports planning, engineering, and execution of subsea decommissioning activities including riser abandonment, pipeline decommissioning, subsea structure interface engineering, and offshore execution support. The Lead SURF Engineer  works closely with structural, marine, wells, construction, SSU, and regulatory teams to  ensure safe, compliant, and efficient delivery of subsea scopes.  

Key Responsibilities  
SURF Engineering Leadership & Technical Delivery  

• Provide senior‑level subsea engineering expertise.  
• Develop subsea technical documentation aligned with Worley and Equinor  
  requirements.  
• Ensure subsea engineering work complies with applicable design codes (API, DNV, ISO)  
  and U.S. offshore regulatory frameworks (BSEE, BOEM, USCG).  

Subsea Decommissioning & Removal Engineering  

• Lead engineering for subsea decommissioning including cutting, recovery, flushing,  
  purging, cleaning, and remediation activities.  
• Develop engineering inputs for removal procedures, work packs, SIMOPS planning, and  
  offshore execution sequences.  
• Support ROV intervention engineering, equipment specification, tooling interfaces, and  
  offshore support requirements.  

Interface Management & Multi‑Discipline Coordination  

• Coordinate SURF interfaces with structural, marine, pipeline, construction, and  
  regulatory teams.  
• Support integration of subsea work scopes into overall decommissioning plans, marine  
  spread plans, and SIMOPS strategies.  
• Respond to technical queries (TQs), vendor clarifications, and offshore execution  
  support needs.  

Documentation, Reporting & Regulatory Compliance  

• Prepare subsea engineering deliverables including basis of design, calculations,  
  drawings, specifications, and technical reports.  
• Ensure subsea documentation aligns with Equinor governing documents and meets all  
  U.S. regulatory requirements.   
• Support audits, technical assurance reviews, and close‑out documentation for subsea  
  decommissioning activities.  

 Qualifications  

• Bachelor’s degree in subsea, mechanical, structural, ocean, or petroleum engineering  
  (advanced degree preferred).  
• Subsea/SURF engineering experience in offshore energy, decommissioning, 
  or major subsea projects.  
• Strong proficiency with subsea engineering tools (e.g., OrcaFlex, Flexcom, PipeLay,  
  SAGE).  
• Experience with subsea decommissioning, removal engineering, ROV operations, and  
  regulatory compliance.  
• Excellent communication, problem‑solving, and cross‑discipline coordination skills.
