Abstract
A double hull ship for the transportation of liquid, high melting aromatic hydrocarbons, such as pitch heated to 200.degree. to 300.degree. C. The tanks are provided with good insulation and with means to introduce inert gas into the tank (1). Heat expansion is allowed for by means of companion expansion joints and sliding bearings (3). Because of the high solidification point of the products, all line systems must be provided with a companion heating system and adequate insulation. A thermal oil system, which simultaneously supplies the emergency heating system (4) of the tank (1), is suitable for this purpose. Separate ballast tanks (17) are installed between the hulls.
