An asphalt tanker is a ship designed to carry bulk asphalt. Its holds and equipment are designed to maintain the cargo at the right temperature for easy loading and unloading.
The asphalt tanker is specifically designed to carry bulk asphalt. However, it sometimes can carry other petroleum byproducts compatible with its holds.
The asphalt tanker has a number of different holds which can be loaded or unloaded simultaneously, taking into account the mechanical stress this creates on the vessel. The holds are heated from within to keep the cargo at the right temperature. This system consists of coils at the bottom and cylinders in the middle and upper parts of the holds. There also are pressure and vacuum valves to maintain optimal pressure within and avoid damage to the holds .
As with other ships, choice will depend on dimensions, engine power and cargo capacity. These vessels are subject to SOLAS regulations. If they carry products other than asphalt, their holds must be drained, increasing port time.
