tl;dr version as I recall: keep holds either mostly full or mostly empty, make assymetric holds and tanks, and use baffles if you have no other options.
- loneranger_11x 7y agoTrue but most of the research is around how to safely handle liquid cargoes. What the article talks about is 2-phase cargoes, cargoes which are expected to behave as solids but could turn to liquid under certain unpredictable conditions. Accounting for these scenarios might involve upsetting the economics of said cargo. Edge cases basically :D
- gingabriska 7y agoBut it seems it can be easily solved having dividers in cargo compartment. Think of box with a grid inside it Once the cargo is filled The grid lines are raised (hydraulics) which compartmentize the whole cargo into blocks. Invidual compartment will not have enough mass of material inside it to break the dividers if designed properly.
