RA355744 - Firewater Pump Replacement

Please note that this advert is for pre-tender market engagement only. Tender is scheduled to be Published via the Delta eSourcing Platform on the 26th of January 2026. Please email Lewis.atkinson@londonenergyltd.com to declare interest and to be included in the tender invite when it is published. A breif description of Scope below. Please find full spec attached. Within the EcoPark, there is a firewater ring main system consisting of: 1) 2 x Firewater Pumps 2) 1 x Sprinkler Header with level control (float switch start) 3) 1 x Fire Water Ring Main (with pressure-controlled start capability) 4) 40 x Isolation Valves 5) 18 x Fire Hose Points 6) 18 x Fire Hose Connections 7) 20 x Fire Hydrants 8) 1 x Crossover Pipeline (for pressure compensation - to be decommissioned and replaced with the jockey pump) The Eco Park Firewater Pump Project aims to install two new diesel firewater pumps and integrate them with the London Energy DCS system. This will enhance the control, monitoring, and visibility of the fire protection system compared to the currently installed setup. Additionally, a new jockey pump will replace the existing crossover system to maintain pressure in the Firewater Ring Main. In addition to the installation of two new firewater pumps and a jockey pump, this project requires enhanced visual, audible, and control capabilities. All components and alarms must be integrated with the SCADA system, ensuring seamless monitoring and control B) Project Scope 1) Replace the existing firewater pumps with two new diesel driven firewater pumps. Disconnection of the existing cables from the current firewater pumps and re-termination into the new firewater pump panel. Extending the existing cables via a JB or cable joint. Installation of any additional cables (to be specified and installed by the contractor). 2) Select, procure and install a new jockey pump to maintain Ring Main pressure. Installation of any additional cables (power and control) for the jockey pump. 3) Upgrade repeater panels to communicate all alarms and faults to the SCADA system. 4) Implement DCS-based control and monitoring of the firewater pumps and jockey pump through SCADA. 5) All technical documentation and drawings are to be provided to LEL by the selected contractor for upload to the London Energy SharePoint, by LEL. ? C) Control Specifications This section outlines the existing control and installation configurations, as well as the required upgrades. Existing Control and DCS Specifications (Electrical): • Auto Start: Currently initiated via the "Firewater Pump Test Panel" located on the turbine mezzanine level and from the Sprinkler Header Level Switch. • Manual Start: Operated through local control panels at each pump and at various push buttons throughout site. Manual stop is only available via the engine choke on the diesel engine. • Indications Available: o Pump running o Battery circuit healthy o Battery charger healthy o Pump on demand o Fail to start o Low oil pressure o High water temperature o Lamp test o Alarm acknowledgement All above indications are repeated on remote repeater panels located in the Turbine Hall (East end). • Audio and visual alarms: Present on both local and remote panels. • No current control or status indication is available in the CCR via SCADA. Fault Indication and Alarms (Current Local Control Panel): o High water temperature o Low oil pressure o Battery charger failure o Battery circuit failure o Fail to start o Pump on demand o Alarm acknowledgment o Repeater panels provide remote visual and audible alarms. o The local test panel enables auto start/stop of firewater pumps o No current DCS connectivity or SCADA monitoring of pump operation Fault Indication and Alarms (New Local Control Panel to be installed): The new firewater pump control panel (provided by SPP Pumps) will use a volt-free contact for a common fault alarm. Individual alarm indications will be shown locally via the HMI. Features include an integrated PCB board with volt-free contacts and designated inputs, dual 10A battery chargers and 12V DC batteries for ignition coil and motor starter. Alarm and Status Indications: o Not in Auto Mode o Pump Running o Pump on Demand (via Float, Pressure or Manual Start request) o Failed to Start o Mains Supply Failure o High Water Temperature o Low Oil Pressure o Low Engine Cooling Water Flow o Low Fuel Level o Low Engine Temperature D) New Control Specifications This section outlines the specifications for the new firewater pump control system to be installed by the selected contractor, including all hardwired electrical requirements, the selected contractor is expected to incorporate the existing manual and automatic start functions. New Control System Specifications: 1. Auto/Remote Start Auto or remote start will be initiated from the Firewater Pump Test Panel. Interconnections required to enable this function are shown in the associated project drawings. o All interconnection work will be carried
