GBWG RecommendationsProposed; Draft schedule for BAUXITE FINES Group Modification of existing schedule for BAUXITE Group C Bauxite Proctor-Fagerberg Test methodology
Consider a classification category cargoes (other cargo instabilities due to moisture also need to be considered).
Group A classification for cargoes to moisture.
Recommendations

methodology
classification category for Group A “liable to liquefy” cargo instabilities due to moisture also need to be
for cargoes that are hazardous - instability due

Safety Considerations• Recognition that the development of a list is
measures to prevent loss of life should be • Recognition that a list may progress such that it exceeds the operational
SOLAS limits for main engine (15deg static/22.5 deg dynamic) and launching of lifeboats (20 deg)
• Awareness that the list could impede lifeboat • A catastrophic roll/sinking may lead to
floating nearby the ship• Regular visual inspection of cargo during the voyage is the best line for early
detection of potential issues.
