The Tanker Management and Self Assessment (TMSA) programme provides companies with a means to improve and measure their own safety management systems.

The programme encourages companies to assess their safety management systems (SMS) against key performance indicators (KPIs) and provides a minimum expectation (level 1) plus three levels of increasing best practice guidance. Self assessment results can be used to develop phased improvement plans that support continuous improvement of their ship management systems. Companies are encouraged to regularly review their self assessment results against the TMSA KPIs and to create achievable plans for improvement.

Aligning their own policies and procedures with industry best practice helps companies to improve their performance and attain high standards of safety and pollution prevention.
