As a tankerman, your duties involve overseeing the transfer and transport of liquid cargo on a barge, ship, or specialized tankboat. The primary responsibilities of a tankerman (variously referred to as an able-bodied tankerman or AB tankerman) are to ensure the safety of crew during loading and transport of the liquid freight. You may work with hazardous materials such as gases and other potentially explosive or toxic substances. You are responsible for inspecting and maintaining liquid transfer equipment onboard and onshore.
