What we examine
- Vessel records
- Navigation data
- Diagrams and incident traces
Materials to prepare
- Logs and records
- Original navigation files
- Meteorological and hydrological information
- Photographs and video
Sample questions
- What sequence of events is supported by the data?
- Are the time and position records consistent?
- Which manoeuvres can be established?
- What are the significant technical limitations of the reconstruction?
- Which input data are insufficient for checking the explanation?
How the work is carried out
- Inventory and agreement of sources
- Building a verifiable chronology
- Analysis of specific navigation questions
Result
A report with a chronology, diagrams and conclusions on supported technical circumstances.
What affects the conclusions
AIS and other records have accuracy and completeness limitations. Independent analysis does not replace an official investigation.
Frequently asked questions
Is a public AIS map sufficient?
Not always. Original data, message frequency, accuracy and comparison with other sources are important.
Will you identify who is at fault?
The examination answers technical questions; authorised persons provide legal assessment.
