Abstract
Abstract A support foundation for a turbogenerator power plant having an oil lubricating system integral with the structural steel of the foundation. An oil reservoir with associated pumping and conduit arrangements are disposed within the structural steel box beams utilized to fabricate the turbine foundation. Provision of the reservoir and associated pumping and conduit arrangements within the structural steel box beams provides a more efficient utilization of available operating floor space and a more efficient operation of the lubricating system.
