This class of Petrosteel tanker is designed to transport hydrocarbon fuel and has a capacity of 7200 gallons with an 800 gallon ullage in JP-8 service and 7000 gallons with a 1000 gallon ullage in RP-1 service. Hydrocarbon fuels are normally offloaded by external pumping units.

The tanker consists of a horizontal tank mounted on a dual wheel, tandem-axle chassis assembly. The tanker is a pump load/offload configuration capable of flow rates up to 400 GPM. The tanker has a single DOT 3AA24000 GN2 cylinder which pneumatically controls the tanker vent, bottom fill/drain valve, and brake interlock system. Included in the design is a liquid level indicator and a high level control mechanism which prevents overfilling. During offloading, a low level sensor communicates with the refueling equipment to preclude pump cavitation prior to completely emptying all commodity. The tank is designed for MAWP of 20 psig but operates at atmospheric pressure. Pressure relief is incorporated on both the tanker vessel as well as the GN2 system.
