Ship navigation risks highlighted
The risks of ecdis error and shortages in navigation knowledge were highlighted by the UK P&I Club. The marine insurance group said ships could be at risk if officers of the watch were not trained sufficiently in the use of ecdis and what to do if this key navigation aid fails.
UK P&I Club loss prevention executive George Devereese highlighted the importance of adequate training around ecdis and navigation. He emphasised the need for ecdis to be constantly updated with electronic navigational charts. He also stressed the need for seafarer assessments and training renewal on ecdis as software and operating functions can change over time.
Mr Devereese underlined the risk from setting too many alarms that can overload seafarers during voyages. He suggested that alerts should be minimised during daily operations, but stringent alarm settings should be maintained for passage planning, which should prevent navigation issues emerging during a voyage.
He also highlighted the risks of misuse of chart ranging and scales. This is because officers can misunderstand the ranging of the charts, by zooming too far in or out. They may not identify key potential navigation hazards during passage planning or during the voyage. This would put the ship at risk.
The UK P&I Club insures over 235 million tonnes of owned and chartered shipping through its international offices and claims network.
