Power solutions company Meissner reports that the successful installation of an 11-t, 1-MVA generator at healthcare company Sechaba Medical Solutions’ data and call centre is the result of the effective coordination of the project’s logistics elements.
The generator, supplied by Spanish generator manufacturer Himonisa, had to be hoisted over a 15-storey building and placed in the basement of the company’s offices in central Johannesburg.
The generator’s large size meant that it had to be lifted by crane and lowered through the central well of the building into the basement area. The generator set included a bulk storage tank that could hold 2 500 ℓ of fuel required to keep the generator running for three days.
Meissner sales director Graham Beyleveld tells Engi-neering News that the project had considerable logistics elements that had to be effectively coordinated for the installation to be successful.
One of the elements that had to be considered was to ensure that power to the company’s critical data servers was maintained.
Beyleveld says that the main power supply to the two-block area, in which the building is situated, had to be switched off. In order to maintain the power supply to the company’s data centre, Meissner provided a rental generator to supply power to the building while the project was under way.
“President and Market streets, in central Johannesburg, had to be closed to accommodate the transporting and assembling of the crane, which was hired to hoist the generator into position,” he says.
The project took seven months to plan and three days to complete. “It had to be completed during a nonrisk timeframe,” says Beyleveld. The installation took place over a weekend and required a 35-person team working in shifts. The team included electrical engineers, project managers, safety officers and fire inspectors, and members of the Johannesburg Metropolitan Police Department were involved in the project.
Meissner senior sales consultant Donovan Ramage explains that a cable system was also installed and connected between the new generator and the power systems in the building.
The existing generator was replaced because the data centre’s capacity had increased and needed a backup power supply that could manage the increased load, says Beyleveld. “The new generator is about four times the size of the old one,” he says, adding that the prospective life of the new generator is 15 years to 20 years.
The generator is enclosed in a soundproof and weatherproof canopy as the volume of noise produced is immense, says Beyleveld.
Ramage says that the placement of the generator in the basement required the proper management and filtering of the fumes produced by the machine. The fumes are filtered and catalysed, and then reticulated out of the building.
