On 14 March 2015, the barge Lasqueti Daughters with 17 people on board, departed Campbell River, British Columbia. Partway into the voyage, the sea conditions deteriorated. Water began shipping on board via the spaces between the bow ramp, the bulwarks, and the main deck, and then downflooded into the forward storage compartment. The Lasqueti Daughters flooded but remained afloat, was abandoned, and was eventually towed to shore and intentionally beached. There were no injuries. The vessel was declared a constructive total loss.

The investigation revealed that the vessel had not been inspected nor was it certified as required by the Canada Shipping Act, 2001 (CSA 2001) and its regulations.

A technical newsletter has been written and published by DNV GL to give an insight and to make recommendations on how to avoid safety risks due to severe corrosion of vessel’s steel structure by way of the box cooler. In the most severe cases that DNV GL has encountered, the bolted flange of the top plate of the cooling box was involved. This led to increased risk of collapse of the top plate.

Extent of damage
A box cooler eliminates the secondary cooling water circuit of sea water inside the engine room. The cooling effect is achieved by natural circulation of the surrounding sea water and is considered to be a cost-effective alternative.
