The programme encourages vessel operators to assess their safety management systems against listed key performance indicators (KPIs) and provides best practice guidance. Best practice is an effective way to minimise the possibility of problems reoccurring. It creates opportunities and optimises performance in crucial areas, such as safety and environmental excellence. Companies should aim to transfer best practices across their fleet through the consistent application of improved processes and procedures.

It is recognised that non-SOLAS vessels operate outside the ISM Code. However, operators of such vessels may use this Guide as a tool to measure and improve their operations. A company that incorporates the guidelines contained in the OVMSA into its management system may be considered as having an active assessment process, even if it does not have ISM as a management system.
