A recent analysis of Gard P&I Club claims data illustrates the correlation between vessel behaviour and the likelihood of accidents.
ccording to Gard, several of the risk factors can be influenced. Fewer accelerations, steady speed, increased vigilance, and better preparations before entering a new port have the potential to significantly reduce the risk of something going wrong. The following are some of the high-risk behaviours which we found to correlate with groundings:
- Speed: The higher the speed relative to the vessel’s service speed, the higher the likelihood of a grounding.
- Proportion of time in median speed: In essence, the fewer speed fluctuations, the lower the risk of grounding. A steady speed during the voyage tends to reduce the risk of grounding.
- River traffic: As indicated above, the more time a vessel spends in rivers, the more likely it is to have an incident.
- Number of port calls: the higher number of port calls, the higher the risk of grounding. This goes for all ports, not just the hot spots.
- Number of unique port calls: The higher the number of different ports visited, the higher the likelihood of a claim. The risk increases when calling at a port not previously visited or not frequently visited by the vessel and this can be attributed to the lack of familiarity that the bridge team would experience during a port visit.
Key risk factors for collisions:
- Calls to large ports: The higher the traffic in a port, the higher the risk. This factor is mostly important for third-party liability.
- Time anchored: The longer a vessel stays at anchor, the higher the risk of a collision, as many vessels are anchored around busy traffic lanes.
- Mileage: The higher the total nautical miles travelled by a vessel throughout a year, the lower the risk of collision. In other words: the more time at sea, the less the likelihood of an incident.
- Speed: Just as for groundings, the higher the speed, the higher the likelihood of a collision. For collisions, the service speed and most common (typical) speed are more useful factors than the max speed.
