THE OPTIMAL FLOATING condition MAKES THE DIFFERENCE
PRECISE DRAUGHT MEASUREMENT, EVEN WHILE SAILING

This system opens up the possibility of optimizing trim and precisely determining a vessel's floating condition. Hull deformations are always known beyond the static load case, even under rough sea conditions. It is a highly accurate solution also monitoring various motion related information which can be used by subsequent systems or by nautical staff. In this way, emission savings and safety aspects can be realized.

PROBLEM DESCRIPTION

INFLUENCE OF THE FLUID MOTION

During sailing through the water, many dynamic effects occur on the ship's hull, which cause a very uneven pressure distribution. This leads to the fact that the measured pressures can no longer be related to the height of the water column and thus the draught of the ship. The presence of waves further amplifies this effect. The result is significant misinterpretation of draft and trim using hydrostatic pressure sensors during navigation.

MEASURING SOLUTIONS

DYNAMIC DRAUGHT AND FLOATING MONITORING

"For all types of vessels where draughts and trim during sailing must be considered, our state-of-the-art Dynamic Draught and Floating Monitoring system provides reliable draught measurements without being distorted by hydrodynamic effects, even while sailing."

Our Dynamic Draught and Floating Monitoring solution (DDFM) continuously monitors the vessel's floating condition by means of sensor fusion. Pressure transmitters measure the hydrostatic draught, one each located at bow, stern, mid ship port and mid ship starboard. With our inertial measuring system (HOSIM2) we compensate any dynamic influence during sailing. This makes the self validating Dynamic Draught and Floating Monitoring system independent of any wave or speed related effects.
