Pre-Commissioning and Commissioning Services

From mechanical completion to start-up, with every system clean, tested and documented

The path from mechanical completion to start-up is where careful preparation pays off. Marvix provides pre-commissioning and commissioning support for pipelines and process plants, verifying that every system is clean, tested and ready for operation.

From mechanical completion to start-up, with every system clean, tested and documented
The path from mechanical completion to start-up is where careful preparation pays off. Marvix provides pre-commissioning and commissioning support for pipelines and process plants, verifying that every system is clean, tested and ready for operation. Our commissioning teams follow structured procedures, clear system boundaries and complete documentation so that handover to the operator is orderly and auditable

Our Scope of Work

  • Hydrostatic and pneumatic strength and leak testing
  • Flushing, cleaning and air blowing
  • Pipeline pigging, gauging and dewatering
  • Drying, nitrogen purging and preservation
  • Loop checks, function tests and interlock verification support
  • Punch-list management and mechanical completion certification
  • System turnover packages and as-built documentation
  • Start-up and commissioning assistance to operators

Codes, Standards and Quality

Test and commissioning procedures are developed to client specifications and recognised codes, with pressure-test safety controls, calibrated instruments and witnessed acceptance. Records are compiled into system handover packages.

Why Choose Marvix for Civil Works

  • Structured procedures: Clear test packs, system boundaries and safety controls reduce risk during pressure testing and start-up.
  • Complete documentation: Auditable records support mechanical completion and smooth turnover to the operator.
  • Continuity from construction: Teams who built the system understand it, which shortens punch-list closure and commissioning.

Pre-commissioning covers static checks and tests carried out before hydrocarbons or process fluids are introduced, such as hydrotesting, flushing, cleaning and loop checks. Commissioning covers the dynamic activities as systems are energised and operated, leading to start-up and handover

Yes. Pigging, gauging, dewatering and drying are included in our pipeline pre-commissioning scope, carried out to approved procedures
