UK MAIB published the preliminary assessment on the grounding of the chemical tanker Chem Alya on 25 October 2021, at Shingles Bank in the Needles Channel off the south coast of England.
The incident
On 25 October 2021, the Liberian registered chemical tanker Chem Alya departed from the buoyed channel and grounded on the Shingles Bank while transiting the Needles Channel on passage to Alexandria, Egypt. There were no injuries or pollution and the vessel, which was undamaged, was refloated later that evening.
Probable cause
The MAIB preliminary assessment, while recognising the Needles Channel was a challenging route, found that Chem Alya’s bridge team did not work effectively together or make full use of the ship’s ECDIS during the transit.
Furthermore, Chem Alya’s passage plan did not consider IMO Resolution A.768(18), which recommended that laden tankers of over 10,000gt do not use the Needles Channel ‘due to tidal problems and apparent movement of the sand banks’. This warning information could also be found on the Admiralty Chart for the area.
Action taken
Based on the findings of its internal investigation, Chem Alya’s managers, ASM Maritime B.V, have taken measures to improve the future safe operation of their vessels by prohibiting them from using the Needles Channel.
The company has also implemented procedures to improve navigational practices and has begun a programme of bridge team management refresher training for all deck officers. The Chief Inspector has written to ASM Maritime B.V, advising the managers of the MAIB’s findings and acknowledging the safety actions they are taking.
The Chief Inspector of Marine Accidents has also written to Associated British Ports Southampton.
While acknowledging that the Needles Channel lies outside its pilotage area, the chief inspector has nonetheless advised the harbour authority to review the information provided by its pilots and VTS operators to vessels intending to use the Needles Channel and, specifically, to draw their attention to the guidance in IMO Resolution A.768(18)
