This Standard establishes uniform procedures for acquiring, processing, presenting, and evaluating shipboard vibration data for sea-going merchant ships of all lengths, and, where applicable, for inland ships and tugboats. It is applicable to both turbine and diesel-driven ships, with single or multiple shafts, 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 vibration standards.
