Objectives, Scope, and Technical Requirements of the Tender

Objectives

The primary objectives of this tender are to ensure the reliable and safe operation of the fire protection system at Matimba Power Station by replacing existing fire pumps with new, compliant units. The project aims to address system adequacy, reduce wear and water hammer, improve control and monitoring, and ensure the longevity of the fire pumps for the remaining life of the station.

Scope

• Design, procurement, delivery, installation, testing, and commissioning of 2 electrical fire pumps, 2 diesel fire pumps, and 2 service pumps.
• Modification of inlet and outlet piping in the pump house.
• Installation of associated pipework, valves, gauges, and electrical connections compliant with Eskom standards.
• Design and implementation of a Distributed Control System (DCS) interface for pump operation and monitoring.
• Provision of training manuals and quality control during construction.
• Decommissioning of old pumps and equipment as required.

Technical Requirements

• Design verification and factory testing of all assemblies in accordance with relevant standards (e.g., IEC 61439, SANS 61641).
• Compliance with Eskom standards for electrical, mechanical, civil, and civil works, including corrosion protection, cable management, and earthing.
• Performance specifications for pumps:
  • Electrical pumps: flow rate ~582 m³/h, head ~114 m, efficiency ≥88.8%, rated power ~216.6 kW.
  • Diesel pumps: flow rate ~582 m³/h, head ~114 m, turbocharged engine ~359 kW.
  • Service pumps: flow rate ~138.9 m³/h, head ~137.8 m, efficiency ≥72.2%, rated power ~72.4 kW.
• Installation of new pipework, valves, and surge protection devices, with compliance to standards (e.g., SANS 61439, NFPA 13).
• Control and instrumentation integration with existing systems, including PLC and HMI interfaces.
• Provision for testing, commissioning, and performance validation of all pumps and associated systems.
• Design considerations to prevent water hammer, excessive wear, and ensure system reliability.

Summary

The tender aims to deliver a fully integrated, compliant, and reliable fire pump system upgrade that enhances safety, operational control, and longevity, aligned with Eskom standards and best practices.
