Fastening connection device suitable for split combined engineering ship

The utility model relates to the field of ships, in particular to a fastening connection device suitable for a split combined engineering ship, which comprises a first ship body, a second ship body, mounting flanges and a connector, the cross section of the connector is T-shaped, and the two mounting flanges clamp the connector together and are fixed through a bolt group. The special mounting flanges and the connectors are arranged at the splicing positions, the bolts penetrate through the two mounting flanges and the connectors at the same time to achieve connection, and the connection strength is high. Waterproof rubber layers are arranged at corresponding positions of the connector, so that water seepage is avoided; the sealing plate is arranged on the back face of the mounting flange, seepage water can be temporarily stored, whether water leaks at the connecting position or not can be seen through the transparent cover plate, and safety is high. 本实用新型涉及船舶领域领域，具体公开了一种适用于分体组合工程船紧固连接装置，包括第一船身、第二船身、安装法兰和连接器，连
