Marine Safety Import Coverage

Recorded Import Coverage

The Phase 2 marine safety import record reports 47,385 incidents from the Transportation Safety Board of Canada (TSB) and 5,876 from the UK Marine Accident Investigation Branch (MAIB). These recorded source counts sum to 53,261 incidents at the cited revision; they are not a current live database count.

The geographic scope stated in the record is North America + UK waters. The counts below cover TSB Canada and MAIB UK only.

Identity and Matching Limitations

The same record states that MAIB rows lack vessel names and IMO numbers. TSB records include vessel details, but older records can lack location coordinates. The record also notes vessel-creation errors requiring correction.

The import counts do not establish cross-source incident matches, a deduplicated cross-jurisdiction total, operator coverage, analyst time savings or matching accuracy. Name-based and IMO-based matching cannot be claimed for MAIB rows without the missing identifiers.

Sample Visualization Data

The sample visualization generator writes fixed example distributions and correlation statistics to sample JSON. It does not rerun the recorded imports or measure correlation results. Its additional authority entries and matching statistics do not establish imported coverage or observed performance.

Basis for Further Analysis

A correlation analysis would require qualified source identifiers, documented matching rules and a retained set of reviewed candidate matches. Source-count arithmetic alone does not establish incident identity or a risk-assessment outcome.
