Legal Definitions - charterparty

A charterparty is a specialized contract in maritime law where a shipowner agrees to lease an entire ship, or a significant portion of it, to another party, known as the charterer. This agreement outlines the terms for the use of the vessel, typically for the transportation of goods, but sometimes for other specific purposes, either for a defined voyage to one or more destinations or for a specified period of time.

Here are some examples to illustrate the concept of a charterparty:

• Imagine a large agricultural company that needs to transport 75,000 tons of grain from a port in Brazil to a buyer in Egypt. Instead of owning their own fleet of bulk carriers, they enter into a charterparty with a shipping company. This contract specifies the exact vessel to be used, the type and quantity of grain, the loading and unloading ports, the expected voyage duration, and the agreed-upon freight rate. The agreement ensures the agricultural company has dedicated shipping capacity for this specific journey without the long-term commitment of ship ownership.

• Consider a global logistics firm that frequently moves containerized goods between Asia and Europe. To ensure consistent shipping capacity and better control over their supply chain, they might sign a charterparty with a shipowner to lease a large container ship for a period of two years. Under this agreement, the logistics firm pays a daily or monthly rate for the use of the vessel, allowing them to plan multiple voyages and manage their cargo routes within that two-year timeframe, rather than booking space on individual voyages.

• An energy company developing an offshore wind farm requires a specialized vessel to transport and install massive turbine components over several months in a particular sea area. They would enter into a charterparty with a company that owns and operates such heavy-lift installation vessels. The contract would detail the specific vessel, the duration of the project, the operational zone, the technical specifications for handling the components, and the daily hire rate. This allows the energy company to have a dedicated, specialized vessel for the entire construction phase of their project.
