5.7MVA Diesel Generator Installation for a South East Telecoms Provider
PROJECT OVERVIEW
GENERATOR INSTALLATION
Three T1900 1900kVA Kohler-SDMO generators were installed on-site
FUEL MANAGEMENT SOLUTION
Installation of three 45,000 litre bunded belly fuel day tanks, complete with internal fuel distribution system
ACOUSTIC ENCLOSURE
All three generators were installed with bespoke acoustic enclosures, designed to achieve a noise level of 75DBA
INTRODUCTION
Initially, WB Power Services were approached by a third party consultant to help design a specification, after they had been appointed by the end user to propose a new power solution, which would act as a back-up power supply for one of their regional data centres. WB Power then worked with the appointed contractors to better define requirements, working through the practicalities of how the project could be delivered without affecting operational capability. Elements detailed within the works included removal of existing power infrastructure, procurement and installation of generating set, acoustic package and a fuel distribution solution.
DECOMMISSIONING & REMOVAL
Following project design and sign-off, the first stage of the project delivery was to decommission, remove and dispose of the following equipment located on-site:
- Three existing generating sets, located in an existing plant room
- Fourth Generating set at the rear of the building
- Attenuation equipment including exhausts
- Day tanks and interconnecting pipe work
WB Power Services were able to conduct this aspect of the project in-house, removing all the four sets by utilising their own Hiab fleet.
GENERATOR SOLUTION
Prior to the generating sets being delivered to site, they underwent a rigorous factory acceptance testing (FAT) process, undertaken at WB Power’s own testing facility in Derbyshire. This included:
- Visual inspection of generating set and acoustic enclosure
- First step load acceptance test
- 4 hours at 100% load
- 1 hour at 110% load
WB Power designed a solution which included the installation of three T1900 Kohler-SDMO prime rated generating sets, which utilised the ComAp control system. Due to sound restrictions on-site, the sets were housed within acoustic containers rated to achieve a noise level of 75 dBA @ 1m FFC, complete with access steps.
FUEL MANAGEMENT SOLUTION
The design also contained provision for a fuel management solution. This included three 45,000 litre nominal bunded belly fuel day tanks, complete with a fuel transfer & fuel polishing systems.
DELIVERY
Finally, the sets were off-loaded and positioned on site. Due to the size of the cranes, a temporary road way and main road closure were undertaken. Once in position, the generators underwent a robust system commissioning and site acceptance process.
In addition to the generating set, WBPS also included ComAp controllers on the sets. WB Power were able to free issue the necessary ComAp control equipment to complete the entire control system package.
All works were undertaken on a strict schedule and budget due to the operational importance of the site. All works were completed within these predefined indicators. WB Power continue to support the engineering team on-site and provide an ongoing service and maintenance package for the on-site generator and equipment. This was a successful diesel generator installation project.
