Auxiliary Seawater and Raw Water Systems
Seawater and raw water packages that strain, pump and distribute water to cooling and service users, with materials and coatings selected for the water they handle.

Role in the plant
Plants, facilities and vessels that draw from the sea, a river, a lake or a well need that water strained, pumped and delivered reliably to heat exchangers and service users. Material selection matters as much as hydraulics: chlorides, solids and biological growth all shape the design.
- Materials of construction selected for the water chemistry and the project specification
- Strainers and pumps arranged for maintenance without interrupting service
- Pumps, strainers and controls function-tested before shipment
Typical package scope
| Element | Function |
|---|---|
| Strainers | Duplex or automatic self-cleaning strainers ahead of the users |
| Pumps | Duty and standby pumps sized to flow and head |
| Treatment | Chemical dosing or antifouling provisions where required |
| Distribution | Headers, valves and piping to heat exchangers and service users |
| Materials and coatings | Alloys, linings and coatings selected for the water chemistry |
| Instrumentation and controls | Pressure, flow and differential pressure instruments with PLC control |
Design basis
Each package is engineered to the project requirements, specifications, governing codes and OEM requirements that apply, for a single installation or a standardized fleet.
| Design input | What it determines |
|---|---|
| Water source | Seawater, brackish, river, lake or well water |
| Water analysis | Chlorides, solids, temperature and fouling potential |
| Flow and head | Flow to each user and system pressure |
| Materials | Material and coating requirements from the project specification |
| Redundancy | Duty and standby pumps and strainers |
| Site | Installation environment, ambient range and area classification |
