Hydraulic deck equipment such as towing / anchor winches and deck cranes are powered by a hydraulic system. The system reliability of this system is directly linked to the condition and cleanliness of the oil. Over time, the oil within the hydraulic system will become contaminated due to the extreme environment, heavy workloads and continuous use. The buildup of these contaminants will start to wear out the components, reducing the lifespan and creating possible unplanned maintenance and downtime.

Doedijns, a Dutch producer of hydraulic power units (HPU), is a preferred supplier for a big tug boat manufacturer. Together with RMF Systems they started a project with the goal to improve oil cleanliness by changing the filtration set-up. Cleanliness goal was set to ≤ ISO 19/17/14. In order to achieve this goal, efficient filtration was necessary.
