On November 14, the Australian frigate HMAS Toowoomba was operating off Japan in support of a UN sanctions enforcement mission. While under way, its props became fouled by a fishing net. To resolve the problem, the crew sent a team of divers down to clear the nets so that the ship could get back under way. They notified nearby traffic that they had divers down by making a VHF radio call and by putting up standard signs.
