Tanker chartering is a fundamental aspect of the shipping industry that involves the hiring or leasing of vessels specifically designed for the transportation of liquid cargoes. Tankers are large ships equipped with specialized tanks to carry various types of liquids, including crude oil, petroleum products, chemicals, and liquefied gases.

The process of tanker chartering involves two main parties: the ship-owner, who owns the tanker, and the charterer, who requires the transportation services for their liquid cargo. The charterer can be an oil company, a trader, a chemical producer, or a shipping company acting on behalf of a client. The terms and conditions of the charter are typically outlined in a charter party agreement, which defines the rights, responsibilities, and obligations of both parties.
