Asphalt Tanker, Bitumen Tanker able to load and maintain cargo temperatures of up to 250°C in fully segregated tanks. The high temperature variations require special design considerations, mainly because of thermal expansion of tanks and pipes. 

All cargo pipes, cargo pumps, cargo ventilation lines and valves are to be heat traced by thermal oil pipes and insulated. Pipes on deck are to be covered by protection. All pipes in cargo tanks are to be double walled with heating thermal oil in the space between.
