On November 22, 2018 the Jawan left port rolling heavily, nearly capsizing fully loaded with 4,327 cattle onboard. Jawan was a livestock carrier reportedly converted from a 630 teu boxship,
Now, the Gulf Livestock 1 has gone down....another converted 630 teu boxship and a ship that also had previous stability issues. In May 2019, stability and navigation issues were identified by the Australian Maritime Safety Authority (AMSA) and the ship's departure was delayed for one week to allow these issues to be resolved (Independent Observer Report 134).
A typhoon is risk enough, especially near the end of a voyage when a ship will be fodder depleted (ie "ballast" reduced) and thus top heavy. If this ship, or its 'sisters' have any additional stability issues, it may not have taken much to push this over the edge.
Thoughts are with the 5800 cattle and the largely Filipino crew (one of which has been saved), the 2 Australians and 2 New Zealanders and their families. This is a unique and risky business and it harms both people and animals.
