ASA S2.25 – American National Standard – Guide for the Measurement, Reporting,and Evaluation of Hull and Superstructure Vibration in Ships

This Standard establishes uniform procedures for acquiring, processing, presenting, and evaluatingshipboard vibration data for sea-going merchant ships of all lengths, and, where applicable, for inlandships and tugboats. It is applicable to both turbine and diesel-driven ships, with single or multipleshafts, but not to outboard-engine driven boats nor to air-driven vessels such as air-cushion vehicles.It contains guidelines for hull and super-structure vibration for:

a) habitability;

b) mechanical suitability.

Data acquired in accordance with this Standard will be useful for:

a) comparing ship specifications with acceptance trial data;

b) comparing various vessels with each other;

c) limited diagnostics of vibration problems; further development and improvement of vibrationstandards.
