ABSTRACT:
Apparatus for protecting against spillage of oil and similar cargoes carried in a tanker vessel upon high-energy impact of the hull 10 of the vessel with another object. The apparatus comprises a series of bladder modules whose walls are made of flexible material of sufficient strength to substantially withstand rupture upon such impact. Each flexible module comprises an inboard cargo-carrying bladder 16 surrounded outboardly by a buffer bladder 12 containing air under pressure. Such buffer bladder 12 may alternatively contain water or other ballast liquid when desired to maintain seaworthiness of the vessel.
