Operations & Maintenance (O&M)

Extending Asset Life While Minimizing Downtime

Highlands O&G Holdings Ltd offers comprehensive Operations & Maintenance (O&M) services with a specialised focus on brownfield rejuvenation. Our expertise lies in upgrading, modifying, and extending the life of existing oil and gas facilities — both offshore and onshore — while ensuring operational continuity and safety.

By working under Simultaneous Operations (SIMOPs) conditions, we execute complex scopes without disrupting ongoing production. Through a disciplined focus on QHSE (Quality, Health, Safety & Environment), risk-based inspections, and robust planning, Highlands delivers high-impact results across legacy assets.
