Corso di Geometria della Nave Prof.Salvatore Miranda Esempio 4 :LPG This vessel is a large and high-speed LPG carrier that is acceptable at most Japanese LPG terminals at full draft condition with about 45,000mt cargo, also equipped with special instruments that enable her to call at high-pressured LPG terminals prevailing in mainland China where import volume of LPG is rapidly expanding in recent years. With this new deployment, “K” LINE’s LPG fleet consists of 3 VLGC (Very Large Gas Carrier), which will provide our customers with a competitive and reliable LPG transport service with maximum safety.

Corso di Geometria della Nave Prof.Salvatore Miranda Esempio 5 :LNG LNG tankers are double-hulled ships specially designed and insulated to prevent leakage or rupture in an accident. The LNG is stored in a special containment system within the inner hull where it is kept at atmospheric pressure and -256°F. Three types of cargo containment systems have evolved as modern standards. These are: ·     The spherical (Moss) design ·     The membrane design ·     The structural prismatic design Most LNG ships use spherical (Moss) tanks, and they are easily identifiable as LNG ships because the top half of the tanks are visible above the deck. The typical LNG carrier can transport about 125,000 - 138,000 cubic meters of LNG, 17 which will provide about 2.6 - 2.8 billion standard cubic feet of natural gas. The typical carrier measures some 900 feet in length, about 140 feet in width and 36 feet in water draft, and costs about $160 million. This ship size is similar to that of an aircraft carrier but significantly smaller than that of a Very Large Crude oil Carrier (VLCC). LNG tankers are generally less: CMS polluting than other shipping vessels because they burn natural gas in addition to fuel oil as a fuel source for propulsion.
