AN AUTOMATIC WAVE PROBE REFERENCE SETTING MECHANISM IN A HIGH SPEED TOWING TANK

The wave generation system in a High Speed Towing T ank (HSTT) generates regular and irregular waves to simulate wave condition during ship model testing. A wave probe is used to measure the height of waves generated by the wave g eneration system which is placed at the centre of the towing tank from the wa ve generation system. Generally the initial wave he ight reference (zero-point) at no wave condition is set manually and it is difficult to set reference accurately and the procedure is ti me consuming. The work aims at development of an automatic mechanism for adjustmen t of zero point in HSTT. The intended system enable s remote monitoring and setting wave probe height reference with better acc uracy minimizing human intervention. The prototype results confirmed the efficacy of the proposed mechanism.
