Safety In Numbers
Fisheries Monitoring and Analysis DivisionNorth Pacific Observer Program
A Two-year Analysis of Safety Incidents in the North Pacific Observer Program:
Can Numbers Be Used to Enhance Observer Safety?
Introduction/Overview• Restructured Observer Program in 2013
– Added previously unobserved vessels from 40-60 feet length overall (LOA) in new Partial Coverage Fleets.
– This report analyzes data collected during the first 2 years of implementation for ROP.
• End of deployment observer survey.• Among many topics covered by the survey, it contains safety related
questions, the data from which will be the subject of this examination.
Background, Dataset Limitations• Operational hypothesis: there will be observable differences in
the types and rates of safety incidents reported between different vessels based on coverage rate, vessel size, and gear type.
• Can the data be used to:– demonstrate patterns across the fleets?– learn lessons about vessel and observer safety? – highlight avenues to improve observer safety in the future?
• Some limitations to the data set:– Preliminary information reported by observers:– May not represent all incidents across the various fleets.
Methods• The data used for this study are:
– Marine casualty incident reports.– Other safety issues encountered and reported that may affect the observers’
safety, health, well being.• Data sources examined for:
– Rates of reported safety incidents by coverage sector.– Rates of reported marine casualty incidents by vessel size.– Rates of marine casualty incidents by fishing gear, fishery, and vessel type.

• Partial Coverage Stratum 40’-57.4’ (11% Target Coverage Rate): Σ = 2518 days.
• Partial Coverage Stratum >57.4’ (16% Target Coverage Rate): Σ = 5361 days.
• Full Coverage Stratum (100-200% Coverage Rate): Σ = 74639 assigned days.

• Rate determined by dividing number of reported incidents by observer assigned days.
• Vessel selection (11/2518) = 0.437%• Trip Selection (15/5361) = 0.280%• Full Coverage (7/74639)= 0.009%

Conclusions• The NPGHOP has an excellent system in place for collecting
safety and deployment related data via observer surveys, enabling dissemination of data to external agencies for investigations, and studies such as this to be performed.
• This can result in continually improving observer safety through fleet education, improvements to safety and sampling gear, and observer training.
• More years of data can continue to be analyzed in the future in an ongoing effort to promote observer safety on board the commercial fishing vessels in our fleets.
