摘要
A liquid-transporting cargo ship has a hull which supports a main deck and several cargo tanks which extend above the main deck. A generally hemispherical cover surrounds the above-deck portion of each tank. The cover is formed of at least three self-supporting metal plating subsections, each of which is connected along its bottom edge to the main deck and along its lateral edges to a meridonal expansion member which is generally tubular in cross section. For cargo tanks designed to carry cryogenic liquid, the cover is made gastight, and an inert atmosphere is maintained in surrounding relation to each cargo tank.
