Skills & Competencies

• Languages and client handling: Professional working English is essential. Working Arabic is a strong advantage. Proven ability to communicate effectively with a multicultural project environment — Arabic‑speaking clients and authorities, Asian site workforces and subcontractors, and European or American engineering consultants and inspectors.


• Leadership: Able to take full ownership of the tank scope, direct a mixed‑nationality site team, and hold subcontractors to schedule and quality commitments.


• Performance under pressure: Comfortable managing hold points, inspection backlogs, hydrotest windows and shutdown/turnaround deadlines without losing quality control discipline.


• Technical communication: Clear, concise, code‑referenced written English for reports, replies to comments, NCR responses and technical clarifications.


• Problem solving: Practical judgement on site issues — fit‑up deviations, distortion, repeated weld rejections, settlement anomalies and coating failures.
