Abstract

A pumping station for a pipeline, in particular an oil or gas pipeline, has a feed pump for delivering a fluid through the pipeline and a combustion engine for driving the feed pump. A hydrostatic system has a hydraulic motor for driving the combustion engine, in order to accelerate same to start-up. The hydraulic system also has a hydraulic pressure accumulator of limited volume which can be filled with a pressurized hydraulic medium to be admitted to the first hydraulic motor, thereby powering the latter. A pressure differential in the hydrostatic system prevailing over the hydraulic motor is variably adjustable, in order to accelerate the combustion engine to a predefined firing speed.
