Beskrivelse
Shipping is of crucial importance to the world economic health with over 90% of world trade involving the transport of goods by ships. Damage to the ship hull is among the top five causes of vessel sinking, causing huge loss of human life and pollution of the seas and coastal areas. The existing repair and maintenance practices, which are based on periodic inspection during dry and wet dock, needs to be improved in order to decrease the number of accidents caused by degradation of the ship hull structure. Acoustic Emission (AE) method can be used for health monitoring on ship hull structures whilst in service and throughout the service life. AE is the transient wave resulting from sudden release of stored energy during a deformation failure process such as crack, multiple dislocation slip, twinning, grain boundary sliding, leaks, structural vibrations, electrical transients, etc. AE technique has been extensively used for the non destructive testing of critical industrial structures such as pressure vessels, tanks, pipes etc. However, the application of AE for ship inspection and monitoring is still relatively new and underdeveloped. In this speech, a review and analysis in structural health monitoring using AE method, on offshore structures especially on ship hulls, will be provided. This speech will be concluded with a discussion on the advantages and disadvantages of the AE method as well as an indication of how AE approach might be included into the structural health and condition monitoring systems of the future.| Periode | 16. okt. 2016 |
