だけ余分に必要となって、深海潜水調査船の空中重量も
増加するなどの問題点があった。When a deep-sea diving research vessel that uses such a device ascends to the sea surface from the deep sea, it removes the weight that was attached during the dive and uses its own buoyancy and the buoyancy of the buoyant material to surface, so the buoyancy material is not required. Since an extra amount corresponding to the necessary impregnating oil 9 is required, there are problems such as an increase in the air weight of the deep sea diving research vessel.
