This document provides guidance for assessing the severity of vibrations measured on bearing housings of shipboard machinery so as to ensure reliable mechanical operation. The criteria apply to the vibration of all non-reciprocating machinery on board surface ships, except for main propulsion machinery. They apply to broadband vibration measurements taken on the bearing housings, of machines under steady-state operating conditions with normal operating conditions of speed and load.
