Industrial Plant Engineering& Design Services

PASAPCO provides multidisciplinary engineering design and technical consultancy for industrial owners and EPC contractors in the mining, metals, oil and gas, and petrochemical sectors.

From concept to commissioning
Explore our disciplines Discuss your project

Our services support plant development and project delivery through four connected areas:

  • Conceptual and basic engineering:Establishing the design basis and defining the principal technical requirements.
  • Detailed engineering:Developing the engineering documents required for procurement and construction.
  • Procurement engineering:Supporting equipment selection and vendor evaluation.
  • Engineering management and commissioning support:Coordination of multidisciplinary engineering, deliverables, and technical interfaces, with support during installation, testing, and startup.

Our specialist disciplines define equipment requirements, design structures and plant systems, and coordinate their interfaces across the facility. Explore the disciplines below to learn more about our capabilities.

Process Engineering

Process design from concept to operation

We develop process solutions through feasibility studies, simulation, equipment sizing, and optimization. Our designs establish the technical basis for plant development, with attention to production requirements, energy efficiency, and water consumption.
