• Understanding of mechanical testing, pressure testing, alignment checks, and commissioning preparation.
• Proficiency in interpreting mechanical drawings, P&IDs, and system boundary documentation.
• Experience with completions management systems (e.g., Orbit, CoConsole, GoCompletions).

Skills and Attributes:

• Strong problem-solving and inspection skills.
• Attention to detail and understanding of system completions and handover principles.
• Excellent communication and coordination skills with multi-disciplinary offshore teams.
• Ability to work offshore in high-risk environments and under pressure to meet handover deadlines.
