Technical maintenance for a shipping company
Technical assistance to resume the settings of the 723+ speed control governors:
- calibration of control signals for scrubber optimization ;
- shaft line power balancing.
After doing some measurements on the governor and engine rack, we removed the governor and installed a new Woodward equipment.
After that, our technician Flavien performed the empty start tests at minimum speed in order to analyze the behavior of the engine and the governor. He then increased speed, step by step, until it reached 1,000 rpm, nominal speed.
Upgrading Woodward equipment and commissioning on site
As part of a modernization, we went on site to replace our client’s old equipment (UG-25 P0) with a UG-25+ P3 which is more recent.
The way of wiring a P0 being different from a P3, we had to redo the wiring of the electric control, and modify the customer configuration to have correct start and operation.

Technical assistance on an industrial site
The customer contacted us for a stability problem on a turbo-compressor. The governor was disconnected from the machine and the speed was managed manually from a valve.
However, when there are load variations on the compressor, the speed of the turbine also varied, and without speed control, the turbine could either stop (overload) or go into overspeed. Our technician Steve therefore reconnected and adjusted the governor to make the operation of the machine more reliable and bring it back into conformity.
