REDUCTION OF SHIPBOARD VIBRATIONS

Excessive shipboard vibrations can be induced by waves, propellers, and machinery. In a case study involving three sisterships, measurements of the excessive low-frequency shipboard vibrations, caused by the low-speed diesel engines, together with observations on slamming in seaways, suggested modifications which successfully reduced the vibration levels and controlled slamming. The vessels had an o.a. length of 144.6 m, a moulded breadth of 22.2 m, a draught of 9.0 m and a deadweight of 16 500t. They were designed for the transport of general cargo in four holds, and provision had been made for the carriage of timber on the main deck and containers on the main deck hatch covers. <Marintek>.
