Liquid Column Damper

For a direct unobstructed view over the ship bow, elevation of the bridge on top of deckhouse is required. With this deckhouse mounted over the engine room cavity, adequate structural stiffness is difficult to incorporate. The present study is intended to carry out a vibration control analysis using tuned liquid column damper (TLCD) which can be used against fore and aft vibration of superstructure. First stage analysis is done for the validation of proposed design of TLCD followed by comparative harmonic analysis of superstructure with and without TLCD, using finite element method.
