Engineering Services

ENPRODE offers services for conceptual and basic design, detailed engineering and owners engineer site support as detailed below.

ENPRODE’s in-house engineering team comprises the following disciplines:
» Civil & Structural
» Electrical, Instrumentation and Control
» Piping & Mechanical
» Process

These teams provide conceptual design, basic design and layout and detailed engineering in all disciplines under one roof.  Areas of specific expertise and experience include power plants, oil and gas, industrial facilities and high performance buildings.
In-house expertise includes that required for power island main components along with the balance of plant such as high-pressure & low-pressure steam systems, fire-fighting, HVAC, redundant and essential power supplies, water treatment, fuel treatment, communications, compressed air, etc.
