This project at Brixton Deverill Water Treatment Works (WTW) involved the design, build, and commissioning of a 7.5-metre long, form 4 Type Motor Control Center (MCC), and included the integration of a borehole pump and variable speed drives, a 110kW setup with harmonic filters, and a bespoke design to fit the unit within an existing floor void.
Key Features and Specifications
- MCC Design: A 7.5-meter long, form 4 MCC.
- Pump and Drives: Borehole pump with variable speed drives.
- Power and Filtering: 110kW with integrated harmonic filters.
- Custom Design: Bespoke design to fit within an existing floor void.
Design Process and Deliverables
Our comprehensive design process and outputs included:
- Site Survey: Detailed analysis of the existing site to inform the design process.
- Steel Work Design: Custom design of the necessary steel structures.
- Instrumentation Survey: Evaluation and documentation of the instrumentation needs.
- User Requirement Specification (URS): Development of a detailed URS to guide the project.
- Heat Loss Calculations: Calculation of heat loss and determination of cooling requirements.
- I/O Schedule: Detailed I/O scheduling to ensure seamless integration.
- Preliminary Panel Schematics: Initial schematics of the panel layout and design.
- Software Development: Custom software programming according to client standards and our bespoke code enhancements.
Specific Challenges and Solutions
During discussions with Wessex Water, several key criteria and challenges were identified:
- Efficient Switch-over: Due to the operational requirements of the site, the switch-over from the existing panel to the new one needed to be scheduled as quickly and efficiently as possible. The BW Controls team meticulously planned the switch-over to minimise downtime and ensure a seamless transition.
- National Grid Limitations: We were required to build a separate ACB panel, meeting all regulatory requirements, to address National Grid operational limitations.
- Non-linear Valve Response: Washout valves were experiencing a non-linear response, which needed to be rectified. Our team implemented advanced control algorithms to ensure linear valve operation and improve system performance.
The BW Controls team successfully addressed all issues and overcame a variety of challenges with consummate professionalism. The project was completed on time, meeting all specifications and exceeding client expectations, resulting in an overall 5-star performance.
