NORTHAMPTON GENERAL HOSPITAL

INTRODUCTION

An incredibly diverse and bespoke project for the WB Power team, the installed solution comprised of incumbent equipment removal, civil works and the installation of 6 x Kohler-SDMO, prime rated generating sets in existing plant rooms. The generating set was installed along with accompanying ancillary equipment such as fuel tanks, plant room attenuation equipment, exhaust flues, switchgear and electrical installation/migration works.

GENERATORS 1, 2 & 3

EQUIPMENT REMOVAL & CIVIL WORKS

Phase one of the project was the supply, installation and commissioning of 3 x Kohler-SDMO T2500 2273kVA Mitsubishi prime rated generating sets complete with set to set & mains synchronising COMAP control panels, situated in an existing plant room. Prior to their installation, the existing generators and accompanying ancillary equipment was to be removed.

Works included:

  • Strip Down Internal Canopies Of Existing Generator Sets
  • Civil Works On External ‘Landing Area’
  • Dismantling Of Existing Exhaust Flues
  • Drain Down & Cut Up 2x 20,000l Fuel Tanks
  • Removal Of External Exhausts

GENERATORS 1, 2 & 3

GENERATORS & ANCILLARY EQUIPMENT INSTALLATION

Once all existing generators and ancillary equipment had been removed, modifications were made to the existing layout of the plant room to allow for the installation of an additional generator, in addition to the existing two. Following this, installed equipment included:

  • Acoustic Plantroom Equipment (75dba @ 1m)
  • 3x Kohler-Sdmo T2500 2273kva Mitsubishi Generators With
  • Accompanying Bunded Slab Fuel Tanks
  • Bespoke Pipework And Flue Systems
  • Remote Radiators, Situated On The Roof

FLUE AND RADIATOR SYSTEMS

Due to the healthcare environment, there were strict sound levels that the newly installed generating sets had to achieve. To accomplish this, WB Power proposed the supply and installation of exhaust gas silencers, which would achieve a sound level of 75 dBA @ 1m. The flues were to be extended to roof level, and were to follow the existing flue route.

GENERATOR REFURBISHMENT

Phase two of the project was the removal of two existing Perkins generator sets. Following their removal from the existing plant room, the generators were transported back to our Ilkeston testing facility to be refurbished.

Works included:

  • Alternator Replacement On Generator One, Utilising Oem Spare Parts
  • Re-Installation Of Generators In New Acoustic Housing
  • Full Service, Load Testing And Proving
  • Civil Works Including Concrete Base And Compound Construction
  • New 200 Hour, Base Tanks Installed With Transfer System

GENERATORS 4, 5 & 6

EQUIPMENT REMOVAL & CIVIL WORKS

The newly installed outlet attenuators for generators 4, 5 and 6.
Phase three of the project was the supply, installation and commissioning of 3 x Kohler-SDMO T1250 1000kVA Mitsubishi prime rated generating sets, complete with set to set & mains COMAP synchronising control panels, to be installed within an existing plant room. Prior to their installation, the existing generators and accompanying ancillary equipment was to be removed.

Works included:

  • Drain Down Existing Bulk Tank And Dispose Of Fuel Tanks
  • Isolate And Remove Existing Generators & Switchboards
  • Remove Gensets, Exhausts, Outlet Attenuators, Swb And Fuel Tank From Site
  • Complete Required Civil Works, Extending Outlets Outside The Room

GENERATORS 4, 5 & 6

GENERATORS & ANCILLARY EQUIPMENT INSTALLATION

Once all existing generators and ancillary equipment had been removed, modifications were made to the existing layout of the plant room to allow for the installation of an additional generator, in addition to the existing two. Following this, installed equipment included:

  • Acoustic Plant Room Equipment (75dba @ 1m)
  • 3x Kohler-Sdmo T1250 1000kva Prime Rated Mitsubishi Generators With Accompanying Bunded Slab Fuel Tanks
  • Bespoke Pipework And Flue Systems
  • Installation Of New Switchgear
  • Installation Of New 200 Hours Bulk Tank With Transfer System

OUTCOME

Following completion of the installation, the sets were commissioned utilising a resistive load bank test. This was conducted by WB Power’s in-house commissioning team, with one of their Commissioning Engineers on site conducting the tests over a 10 day period. Whilst on-site the Engineer was also able to deliver formal training to the Hospital Engineers. A detailed analysis of the project found that the generator and accompanying ancillary equipment was delivered by our Projects Team within predefined time frames and on-budget. All predefined hospital requirements were delivered, meaning the project was a great success for WB Power
