Dropped object: Tank dog
The MSF has published a safety alert regarding an incident in which a hatch securing ‘dog’ was found on the cargo deck of a platform supply vessel (PSV). The item was close to the stowage position of a back-loaded tank. It was established that the grub screw holding the anchor pin in place had worked loose, allowing the ‘dog’ to come adrift and fall to the deck of the vessel.
