REPORT ISSUED BY MAIB ON THE GROUNDING OF GENERAL CARGO VESSEL CELTICA HAV
At 1438 on 27 March 2018, the Bahamas registered general cargo vessel Celtica Hav grounded on a stone training wall in the approach channel to the River Neath, Wales.
The vessel had a harbour pilot on board at the time who had control of the steering and speed. Celtica Hav was quickly re-floated and manoeuvred clear of the training wall.
It suffered extensive shell plate damage to the bottom of its hull, which resulted in water ingress to several ballast tanks and flooding in the engine room.
The flooding was contained using the vessel’s bilge and ballast pumps, and submersible salvage pumps provided by the harbour authority. There were no injuries to personnel and no damage to the environment.
Safety lessons – a detailed pilotage plan had not been made by either the ship or the pilot, and the master/pilot exchange did not cover all hazards, including that posed by the training walls.
– the pilot did not have full positional awareness when Celtica Hav left the dredged channel and did not fully appreciate the risk of grounding on the training wall.
– the vessel’s electronic navigation equipment was not adequately utilised to monitor the vessel’s position and assess its progress.
Recommendations Recommendations have been made to the Neath Port Authority (2019/101 and 2019/102) and HAV Ship Management NorRus AS (2019/103 and 2019/104) to improve the planning of pilotage and the quality of the master/pilot exchange of pilotage information.

BEWARE THE DANGERS OF ALUMINIUM DROSS
The UK P&I Club and the TT Club have published advice following an incident involving a consignment of aluminium pellets (or dross) that was found at the port of loading with the doors and sides of the container blown out. The terminal arranged to test the samples, as there was no evidence that the unit had been dropped during handling.
The test results indicated that aluminium dross is highly susceptible to a reaction with chlorides when moisture is present. The commodity produces gases when exposed to moisture and the build-up of gasses was considered the most likely cause of the container exploding.
The container was damaged beyond repair and it is understood that some lines and ports are refusing this cargo commodity.
According to the UK Club, at the time the material is tested, before filling the container and subsequent shipping, the moisture level is such that the reaction with the commodity does not generate gas at enough rate to meet the UN hazard class 4 criteria. However, the reaction is slow, so after some time there is the possibility of an explosion. This may deform the side panels, but it is also able to ‘pop’ the container where it is joined to the frame.
The UK Club suggested that carriers work with shippers on any bookings for recycled aluminium carried in bulk in containers to gain more certainty about pre-shipment controls necessary to avoid excessive moisture content that may lead to a build-up of gasses while transit.
