Alarm Monitoring System

Condition Monitoring

Van der Velden Marine Systems developed dedicated software for data analyses, displaying ship and product performance monitoring, giving the owner and user (captain/helmsman) more information about the condition of relevant components. This results in more efficient ship behaviour with a reduction of fuel consumption and emissions. At the same time, less overload on rudder and steering gear will stretch out the interval of the maintenance cycles and the lifespan.



  • Full insight into the performance and current status of ship components. The software algorithms will even predict the replacement of the most crucial parts in the rudder(s) and steering system.
  • Onboard monitoring: With class approved build-in LED Touchscreen displays (size 5”, 7” and 10.5”), this system makes feedback possible at any time (24 hours a day, 7 days a week). It is equipped with its own WiFi system access. It can be accessed from anywhere on board (repeater WiFi antennas required).

  • Shore-based monitoring: Using 4G GSM or at sea the on board Broadband Satellite data transport systems, a full insight of on shore based stations can be achieved, giving superintends and ship managers a good view of the behaviour of all ship movements.
  • Service monitoring: DMC's service engineers will connect mobile service stations directly to the PMS2020 for failure analyses and repair jobs.

Barke Optimised Steering System (BOSS™)


The BOSS is able to calculate the rudder forces for specific angles, which are not measured or displayed by any of the ship’s navigation systems.

The BARKE® rudder is the solution if you are looking to invest in today and tomorrow.
