With a view to the anticipated increase in the amount of ethylene moved around the world by ship, and also of other products such as mixes of ethane and higher hydrocarbons,this paper will describe a gas tanker with a cargo volume of approximately 30,000 m3. This vessel has been based on a new tank design that enables the accommodation of a relatively large loading volume in a ship with given parameters like length and beam. Existing ethylene carriers of the semi-refrigerated type have a transport volume up to 12 000 m3. They allow a transport pressure up to 5-7 bar, even if ethylene is transported at atmospheric pressure and at a temperature of —104°C (169 K). By using a higher tank pressure, these ships are able to transport a wide range of other liquid gases and chemicals besides ethylene. Existing liquefied gas carriers of bigger sizes (approx. 20,000 m3 to 75,000 m3) are designed as fully refrigerated types. In order to offer to the future gas transport market a most flexible gas carrier, we decided to design the 30,000 m3 ethylene, LPG, NH3 carrier as a semi-refrigerated type.
