3MVA Diesel Generator Installation for a Cornwall Hospital
2 x 1650kVA Kohler-SDMO generating sets installed on-site
FUEL MANAGEMENT SOLUTION
Four fuel tanks were installed as part of an intricate fuel management solution, totalling 121,600 litres of fuel
PLANT ROOM INSTALLATION
The generating sets were installed in an existing plant room with limited space
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 2 x 1650 kVA Kohler-SDMO generating sets in an existing plant room. The generating sets were installed along with accompanying ancillary equipment such as a fuel management solution, plant room attenuation equipment, exhaust systems and full commissioning/testing.
DECOMMISSIONING & REMOVAL
The initial stage of the project involved the removal and ‘disposal’ of the sites incumbent generating set, and it’s accompanying ancillary equipment. Removed equipment included:
- 2 x Generating sets
- LV Switchboard
- Fuel tanks
- Attenuation equipment
- Exhaust silencer and flue
Due to WB Power’s operations in the used generator market, a buy back price for each incumbent generating set was included in the project quote, with the agreed price being deducted off the total project cost. WB Power also provided a price to clean and de-gas the existing bulk fuel tanks prior to removal, ensuring they would be efficient if utilised in the future.
Following a detailed analysis of the hospitals power requirements, WB Power proposed the installation of 2 x 1650kVA Kohler-SDMO, three phase, prime rated generating sets. Utilising the ComAp IGNTC-BB synchronising control panel, the sets were installed with additional bespoke work, which included:
- Automatic lubricating oil replenishment system
- Fusible link released fire valve
- Enclosed spring anti-vibration mountings
- Optima red top (AMG) batteries (duty/standby)
FUEL MANAGEMENT SOLUTION
The generating sets were configured to be fed fuel from two 3,200 litre bunded day tanks, which were installed within a durasteel enclosure. These tanks would act as an immediate fuel source and were installed below the air inlet attenuators, within a concrete wall, offering additional support and protection.
- The days tanks were fed fuel by two 56,000 litre bunded bulk fuel storage tanks, which came complete with:
- Tank mounted duty/standby fuel transfer pumps
- Tank mounted fuel polishing system
- Duplex fuel strainers and differential pressure indicators
- C2020 Contents gauge
- Balance connections and valves
These tanks were installed with a tank access ladder with a platform between, ensuring engineers could easily access to the manways and level switches.
The generating set was installed with both inlet and outlet attenuators, which were designed to achieve a sound level of 72dBA @ 1m per set. The attenuators were finished in enhanced paint and were supplied with weather louvres and motorised inlet/gravity outlet louvres.
WB Power provided a twin-wall exhaust flue for each new generating set. The flues were designed and installed to exit the room adjacent to the discharge attenuators. They then rose up a mast to a height of 15m. Due to incoming emergency aircraft on the hospital grounds, the flue included three aircraft warning lights and lightening protection.
