September 2017 - AMSA produced advice on Dynamic Separation - Based on research conducted by the Global Bauxite Working Group and endorsed by the fourth session of the International Maritime Organisation’s Sub-Committee on Carriage of Cargoes and Containers (CCC-4), it is probable that a different phenomenon dubbed ‘dynamic separation’ was responsible for the "Bulk Jupiter" tragedy.

Updated IMO circular September 2017
The International Maritime Organization (IMO) has taken action to warn ship Masters of the possible dangers of liquefaction associated with carriage of bauxite, following consideration of findings from the investigation into the loss of the 10-year-old Bahamas flag bulk carrier Bulk Jupiter, which was carrying 46,400 tonnes of bauxite when it sank rapidly with 18 fatalities in January 2015.

Bauxite is described in the International Maritime Solid Bulk Cargoes (IMSBC) Code as a Group C cargo. However, subsequent work undertaken by the industry Global Bauxite Working Group (GBWG) in conjunction with competent Authorities indicate that Bauxite presents a risk caused by moisture. As such some Bauxite cargoes should be treated as Group A cargoes.
The Sub-Committee on Carriage of Cargoes and Containers (CCC), at its second session, approved CCC.1/Circ.2 to raise awareness on the potential risks posed by moisture in the carriage of Bauxite. The advice provided by this circular has been superseded by the outcome of the research undertaken. This circular supersedes CCC.1/Circ.2.
