A tanker designed to carry molten sulphur at high temperature, in independent, insulated tanks. The sulphur tanks are secured against rolling and pitching movement, but are allowed to expand or contract with different cargo temperatures.
Rockwool or equivalent insulation, covered with galvanised sheet, is fitted to the exterior of the tanks. The entire cargo handling system (pumps, valves, pipes and fittings) is fitted with heating jackets, and heating coils are arranged in the cargo tanks.
