Provides guidelines, and specifies requirements and procedures for the measurement, diagnostic evaluation and reporting of structural vibration of ships, excited by the propulsion plant.

This part of ISO20283 gives guidelines, and specifies requirements and procedures for the measurement, diagnostic evaluation and reporting of structural vibration of ships, excited by the propulsion plant. Structural vibration can be of global or of local nature. Here, primarily global vibration is dealt with.

Local vibration of deck structures from a habitability point of view is dealt with in ISO6954. Occurrence of local vibration leading to fatigue damage is rare and strongly related to the individual configuration. Therefore, no general guideline for the measurement of such type of vibration is provided within the scope of ISO20283 (all parts). For reference, some basic information regarding the design of structures with respect to local structural vibration is provided in AnnexD.

This part of ISO20283 does not consider transient ship vibration phenomena, e.g., as excited by slamming.

Even though torsional shaft or crankshaft vibration can in some cases cause relevant structural vibration, they are not considered here. In this connection, reference can be made to the relevant classification rules and ISO20283-4.
