Abstract: The ocean is always one of the biggest blind spot of traditional communication technologies. Because of lack of effective means of communication, resulting in information communication difficulties between ship and shore, highly informatization of offshore marine engineering ships have become floating “information islands” in the sea. Beidou Satellite Navigation System has integrated navigation and communication, which has provided a feasible technology way to solve the
 Vessel-Shore Integration. This paper proposed a Beidou cluster data transmission technology solution based on short message communication principle of Beidou RDSS (radio determination satellite Service), which solves the problem of large amount of data transmission for marine engineering ships. The software can transmit thousands of physical quantity containing ship machine state data, construction condition data, position information to shore command center in real-time through the development of the communication protocol, the establishment of an effective algorithm of data processing and compression algorithms, which realizes the Vessel-Shore Integration of offshore operations and provides an information technology security for the ship scheduling of production and business management.
