'Singing' Propellers Phenomenon Controlled

A joint research project carried out by Wärtsilä and City University London has succeeded in identifying the specific design parameters that create the risk of 'singing' propellers. Though rare, 'singing' is nevertheless an annoying problem that occurs as a strong tonal noise originating from the propeller, thus causing a negative effect to onboard comfort levels. The research programme reached its conclusions in December 2015. The problem has long been recognised in the marine industry. While the general perception has been that the frequency of the propeller blades' vibration mode coincides with the frequency of the hydrodynamic excitation forces at the trailing edge of the blades, the current research indicates that there is more complexity and sensitiveness to this hypothesis.

The Polar Code has been under development at the IMO for a considerable length of time but will reach fruition during 2014 after which it will be offered to the various nations to ratify. The Code seeks to provide a common reference for those ship owners, designers and – more importantly, perhaps – the ship users who will be operating inside the Arctic or Antarctic regions. The South Polar Region is already covered for a host of aspects by the Antarctic Treaty which has now been in force for many years.

IMarEST President's Lecture Focuses on Failure

Engineering failures in the marine industry certainly cost time and resources to correct and, sadly, sometimes resulting in loss of life. At his President’s Day Lecture, Professor John Carlton FREng, Professor of Marine Engineering, City University London and the 109th President of the Institute of Marine Engineering, Science and Technology (IMarEST), will retrospectively discuss some of the marine failures that he has encountered, with the aim of teasing out the underlying issues that have contributed to their causes. The President’s Lecture will be held Tuesday 11 October at IET London in Savoy Place, London WC2. Tea will be served from 17.30, the President’s Lecture will begin at 18.00 and a Reception will follow at 19.00.
