What is Contracts Of Affreightment (COA)?

Contracts Of Affreightment are used when a shipowner or operator agrees to transport a given quantity over a fixed period of time. Unlike other charter parties, no specific ship is named in the charterparty. It is up to the owner or operator to provide ships as needed for the project. With tankers, due to the sensitivity of port states regarding oil pollution, it is likely that the contract will include specific requirements regarding  the  ships  employed,  which  would  probably  extend  to  the  owner having to provide the charterer with a list of ships likely to be employed in the contract. Contracts Of Affreightment gives the owner considerable freedom to manage his fleet to the best advantage, even to the extent of ‘chartering in’ ships if his own fleet is engaged in more profitable employment elsewhere. Contracts Of Affreightment is common with owners of small coasters employed in short voyages, as it saves having to charter a ship for each movement. Contracts Of Affreightment is also used by government charterers for international trades.There are several standard charter parties for Contracts Of Affreightment, one of which is the Volcoa – basically for dry cargo – and the Intercoa.
