LPG Carrier Vessel 3D model

The transportation of liquefied gases by sea began in 1934 when a leading global company introduced two combined oil/LPG tankers into service. These ships were essentially oil carriers that had been converted by adding small, riveted pressure tanks for transporting LPG into cargo compartments. This innovation enabled the efficient transport over long distances of substantial quantities of an oil refinery by-product that offered distinct advantages as a domestic and commercial fuel source. LPG is odorless, non-toxic, has high calorific value, and low sulfur content, making it extremely clean and efficient when burned. Today, most fully pressurized oceangoing LPG carriers are equipped with two or three horizontal, cylindrical, or spherical cargo tanks and have typical capacities ranging from 20,000 to 1,000,000 tonnes. Their length overall typically spans between 220m and 260m. However, in recent years a number of larger-capacity fully pressurized ships have been built, particularly a series of 10,800 m3 (380,000 cu ft) vessels constructed in Japan between 2003 and 2013. Fully pressurized ships continue to be constructed in significant numbers, representing a cost-effective, straightforward method for transporting LPG to and from smaller gas terminals.
