ISO 20283 Mechanical vibration — Measurement of vibration on ships
ISO 20283 consists of the following parts, under the general title Mechanical vibration — Measurement of
vibration on ships:
— Part 2: Measurement of structural vibration
— Part 3: Pre-installation vibration measurement of shipboard equipment
— Part 4: Measurement and evaluation of vibration of the ship propulsion machinery
The following part is planned:
— Part 1: General guidelines
This first edition of ISO 20283-5 cancels and replaces ISO 6954:2000, which has been technically
revised with the following changes:
— crew and passenger spaces were clearly defined;
— measurement conditions also include dynamic positioning (DP) mode;
— guideline values were changed from pairs of lower and upper values representing the range of
commonly accepted vibration magnitude to just one maximum value. This gives a clearer indication
when this document is referred to in commercial contracts or similar. The actual guideline values
are somewhat severer accounting for the technical progress made.
