In a system for transaction at sea, a plurality of offshore wireless network apparatuses is separately provided on different marine vessels to form a network at sea, so as to transmit supplies-to-buy information sent by a ship to at least one of a plurality of ground wireless network apparatuses via the offshore wireless network apparatuses; and a transaction control platform linked with the ground wireless network apparatuses receives and analyzes the supplied-to-buy information in order to procure the supplies needed by the ship. Therefore, transaction services at sea can be provided to a ship navigating the sea.
