Objective The objectives of this Guide are to: Provide reliability based programs to address improved maintenance program performance. These efforts can provide increased asset value and result in improved asset safety and operational effectiveness. An additional benefit is a more clear definition of asset health so that unanticipated repairs are minimized and operations are less prone to delay. Provide requirements for improved reliability which seek to reduce the risk to personnel@ vessels or marine structures@ and the environment. This will potentially reduce the economic consequences due to a machinery failure which may otherwise occur more frequently without the application of a rational maintenance strategy@ as provided for by this Guide. Foster effective asset management philosophies for new or existing assets and assist in providing credit toward the requirements of Special Periodical Survey of Machinery.
