What We Do
Engineering Services
Integrated process, automation and field instrumentation capabilities for offshore and onshore oil & gas facilities — from concept through operations.
Process Engineering
Front-end, detailed and operational process engineering for offshore and onshore facilities, including wellhead platforms, FPSOs/MOPUs/FLNG, gas plants, LNG trains and petrochemical complexes.
Discuss Your ProjectFront-End Engineering & Design (FEED)
- Process design basis and concept development.
- Heat and Material Balances (HMB) and Process Flow Diagrams (PFDs).
- Piping & Instrumentation Diagrams (P&IDs) – preparation and review.
