without cargo tanks. No water in cargo tanks—practically no
corrosion; increases expected lifetime. Easy access to frame
structures that are mainly in ballast spaces. Almost complete
discharge of cargo. Easy tank cleaning. Increased environmental
protection. B. Added protection against cargo outflow in case of
low-impact casualty. Efficient stripping and tank washing; good
cargo turnout. C. Faster cargo unloading (discharging, tank
washing, stripping) D. Psychological shield in low-impact
groundings. (However, due to structural rigidity may cause
fracture of shell plating.) Politically acceptable design. E.
Greater cargo outturn. Fewer tank washing machines. Greater
protection from minor contact damage or oil spill. F. Easier to
load and discharge. Good protection in
