Division 4 ANALYSIS

This part includes a number of discrete sections, providing an analysis of each accidental event, with comments relating to the results of any relevant examinations or tests conducted during the course of the safety investigation and to any safety action that might already have been taken to prevent marine casualties.

These sections should cover issues such as:

• accidental event context and environment,

• human erroneous actions and omissions, events involving hazardous material, environmental effects, equipment failures, and external influences,

• contributing factors involving person-related functions, shipboard operations, shore management or regulatory influence.

The analysis and comment enable the report to reach logical conclusions, establishing all of the contributing factors, including those with risks for which existing defences aimed at preventing an accidental event, and/or those aimed at eliminating or reducing its consequences, are assessed to be either inadequate or missing.
