To achieve continuity in the operation of machinery and systems, maintenance is required. Nowadays focus is to attain more effective maintenance strategies and to move away from the old-fashioned maintenance philosophy of Corrective Maintenance, CM in favour of Preventive Maintenance, PM (Johansson, 1997). While shore based industries have been developing their maintenance further by implementing Condition Based Maintenance, CBM, shipping has continued to utilize less refined maintenance approaches (Lazakis, 2010). The purpose of this thesis was to investigate why CBM and vibration monitoring seem to be rare aboard ships, what obstacles there are and to some extent see if they can be managed and also to examine what means of maintenance are used in industrial as well as maritime applications. The data for this thesis was gathered through semi-structured interviews with personnel from ships, shipping companies, industries and vibration experts to ensure a broad spectrum of knowledge and thoughts. The results of this thesis show a distrust towards vibration monitoring, while other means of condition monitoring such as lube oil and thermal analysis is common on board. This distrust can be related to the complexity of the subject of vibration monitoring as well as a lack of training, thus, lack of knowledge. Vibration monitoring is also regarded as an expense whence there is little to gain due to critical systems on board having redundancy.
