Subjectwake survey system
AbstractPresently at IMD, wake created by ship hulls can be measured using the wake survey system. It provides a means of measuring the water flow of a ship hull, in order to determine the flow velocity and direction at the propeller plane. Currently, the measurements are done using a five-hole pitot tube probe head, containing pressure transducers. From this data, propellers can be designed for the different ship hulls at different conditions. Before performing wake survey, preliminary steps have to be taken. These steps involve purging the air from the probe head, pre-water testing, and depth checks in the water. During the work term, these steps showed that the probe head was reading skewed measurements.
