Process
Most of the projects begin with the process engineering effort to define the basic parameters of the project based on client requirements. Studies are conducted for process optimization, material balance, economic evaluation, and system studies.
These activities lead to the preparation of Process Flow Diagrams, P&ID's, main equipment specifications, line sizing, etc.
Civil/Structural/Architectural
Land survey, site and soil improvements, drainage, foundations, structures, supports, roads and building design are handled by these disciplines. Design calculations, material specifications and detail construction drawings are also prepared.
Piping
Using the P&ID's, the piping discipline prepares the equipment layout to establish the plant general layout to establish the plant general arrangement. Line studies are conducted to optimize the piping layout which also includes layout information from other disciplines. Where required, isometric drawings are also prepared to further define a complicated piping layout. Stress analysis, piping specifications, racks and sleeper design are integral parts of the piping discipline activities. Field surveys are conducted to identify the tie-in point in an existing plant.
Mechanical/HVAC/Fire Protection
These disciplines specify and select equipment including pumps, compressors, vessels, material handling, and packaged systems. HVAC and fire protection design provide environmental control for the plant, personnel protection, and compliance with code requirements.
Instrumentation
Together with the Process, this discipline defines the control systems for input to the P&ID's. This is further defined by logic and/or ladder diagram, loop diagrams, instrument data sheets, control panel design, and instrument location drawings.
Electrical
Electric power distribution, control, lighting, grounding, and cable/conduit layout are the responsibilities of this discipline. Substation design, equipment sizing and specifications, system fault level studies, protection system coordination, motor controls up to 15kv, and UPS supplies for a plant can be fully engineered.
Safety systems including emergency exit lighting, fire and gas detection system, alarms, and communication systems including CCTV system are prepared.
