The hydraulic units or powerpacks, often abbreviated as HPU, are custom-made for all types of Brusselle steering gears, always in accordance with the applicable classification regulations (BV, LROS, DNV, GL, CCS…). When electrically driven pumps are installed, electric starter cabinets can be provided. These starter cabinets include controls for starting/stopping the pumps and handle the requested alarms.
The powerpack includes 2 hydraulic pumps, each driven by an electric motor equipped with standby heating, valve blocks, relief valves, double or triple oil tank (fully redundant) with various compartments, associated filters, alarms, valves, …
In most cases, Brusselle also provides the starter cabinets for the pumps. The cabinets are equipped to handle starting and stopping and alarm signals, but this excludes valve operation and integration with the Follow Up system and the auto- and gyro-pilot. The cabinets can be supplied as separate units or installed on the frame of the powerpack.
