3. Formal Safety Analysis of a generic fishing vessel

In this study, formal safety analysis proposed addresses the high risk areas which need design
and /or operational attention. The generic fishing vessel (hypothetical vessel) is a vessel of any
method of fishing. Fishing is cyclic with the following phases of life:

Design and construction,
Commisioning,
Berthing, unberthing, entering port and leaving port,
Fish loading and unloading,
Dry dock and maintenance period,
Decommisioning and scrapping.

The status of the ship‟s function changes in the phases of life. The factors that will affect the
safety and reliability of the vessel are as follows:

Human,
Communications,
Emergency, response / control,
Machinery, power /propulsion,
Management system,
Navigation,
Piping and pumping,
Mooring / towing, anchoring, lifting,
Electrical systems,
Structure and payload,
Bunkering / storing,
Stability, manoeuvrability,
Pollution prevention,
Habitable environment.
