- Carbon steel and alloy pipe spools
- ASME code-stamped pressure vessels
- Pressure vessel repairs and alterations per ASME/NBIC
- Process skid modules/skid assembly
- Structural steel
Construction
Our direct-hired field crews safely and efficiently perform the major phases of field construction, from initial site work to startup.
- Earth/site work
- Civil
- Structural
- Mechanical
- Electrical and instrumentation management
- Testing
- Commissioning
- Piping
- Sub-contract: I/E construction and soft crafts
Optimized for Excellence
The true cost and schedule savings of working with OPD are realized when we fully execute a project from early-stage planning through start-up. From conceptual design to fabrication and warehousing, we deliver full EPC services with on-site leadership and OPD construction crews.
