Caterpillar Inc. has announced that Cat diesel generator sets ranging from 650 kW to 3,100 kW have been added to the list of products receiving Special Seismic Certification Preapproval (OSP) from the California Office of Statewide Health Planning and Development (OSHPD).
With this preapproval, Cat C27, C32, 3512C, 3516C, 3516C-HD and C175-16 generator sets may be installed by hospitals and other critical care facilities without the need to perform state-mandated shake testing on the actual units delivered, reducing the time needed for installation and commissioning. The Cat C27 generator set with optional enclosure and rigid-mounted, sub-base fuel tanks also received OSHPD preapproval.
Structural engineers working in conjunction with The VMC Group conducted independent shake testing on Cat power generation equipment at the Caltrans Seismic Response Modification Device (SRMD) Test Facility at the University of California, San Diego. Cat equipment received special seismic certification at SDS 2.1g, which far exceeds the minimum SDS 1.93g required by OSHPD and the California Building Code.
“Healthcare facilities and the patients they serve have a continuous, critical need for uninterrupted power, and they require durability and reliability well beyond the minimum required by OSHPD,” said Jordan Levitt, engineering manager for Caterpillar’s Electric Power Division. “With this pre-approval, Caterpillar has once again demonstrated our ability to respond to market needs.”
To receive Special Seismic Certification Preapproval, manufacturers of generator sets must submit documentation that shows the equipment has passed a shake test in accordance with ICC-ES AC-156, meeting seismic requirements for an earthquake.
