Delivering surface engineering for field development and energy transition.
We support operators and investors with facilities, infrastructure and integrated engineering solutions from concept through to delivery.
Project Lifecycle
End-to-end consulting engineering across energy, subsurface and infrastructure projects — from first principles to optimised, decarbonised assets.
Three pillars. One integrated practice.
From investment-grade advisory to fully integrated field development — delivered by engineers who have stood on the platforms and signed off the drawings.

A snapshot of recent engagements across upstream, midstream and energy transition assets.
Feasibility Study for Onshore vs Offshore
OPC was engaged to provide an independent and unbiased Pre-Feasibility Study to assess two alternative LNG storage solutions for an LNG import terminal currently under construction in Indonesia.
Technical Advisory Services for Geotechnical Investigations
OPC provided Owner’s Engineer support for geotechnical investigations associated with an LNG production and jetty facility in Timor-Leste, delivering independent technical oversight and advisory services.
Owner’s Engineer Services for LNG Regasification Terminal
OPC was engaged to deliver comprehensive Owner’s Engineer services for the development of a 77 MMSCFD LNG regasification terminal in Indonesia.
Independent Technical Insight for Investment Decisions
Successful investments depend on a clear understanding of technical risk, value and project viability.
OPC provides independent technical advisory services to investors, operators and developers across the energy sector. Combining commercial awareness with practical engineering experience, we deliver objective assessments that support confident decision-making.
Our expertise covers technical due diligence, asset evaluation, concept screening and strategic advisory. We help clients identify opportunities, test assumptions and understand the key drivers of project success.
Concept design, FEED, engineering
Successful facility design combines technical expertise with practical experience. Our engineers understand how assets are built, operated and maintained, delivering solutions that work in the real world.
OPC provides concept design, FEED, detailed engineering and operational support for surface facilities across the energy sector. We balance safety, operability, efficiency and commercial performance to maximise value throughout the asset lifecycle.
Our experience spans upstream oil and gas facilities, LNG infrastructure and emerging energy developments. We support clients across hydrogen, e-fuels, carbon capture and decarbonisation projects, helping deliver infrastructure that meets today’s needs and future demands.
Combining subsurface and surface expertise
Successful developments depend on the alignment of subsurface understanding, facilities engineering and project execution.
OPC’s Integrated Field Development approach brings these disciplines together from concept selection through to operation. By considering the full development picture early, we help clients reduce risk, improve decision-making and maximise project value.
Combining subsurface and surface expertise, we develop practical, commercially focused solutions across upstream oil and gas, LNG and gas processing, and emerging energy transition and carbon management projects.
Maintaining a clear line of sight from reservoir to facility enables clients to progress projects with greater confidence, efficiency and certainty.
Embedded expertise
working as part of your team.
We don’t just deliver in isolation. Our engineers integrate into client teams, build capability locally, and leave a stronger organisation behind.
