Abstract

The invention provides a novel dead rudder structure of a maritime work auxiliary ship. The novel dead rudder structure comprises a flow guide section, a section connected with a ship body, a main body section, a flow removal section, a lower transition section and a bottom plate. The main body section is connected with the ship body through the section connected with the ship body, the flow removal section is connected to the main body section and the first end of the section connected with the ship body, and the flow guide section is connected to the main body section and the second end of the section connected with the ship body and is connected with the ship body; and the bottom plate is connected with the flow removal section, the main body section and the flow guide section through the lower transition section. According to the novel dead rudder structure of the maritime work auxiliary ship, the hydrodynamic performance is further optimized, and the energy-saving performance andthe navigation performance of the ship are improved.

Description

Technical field[0001]The present invention relates to the field of dead rudder, in particular to a novel dead rudder structure of an offshore auxiliary ship.Background technique[0002]Offshore auxiliary vessels are used to tow, handle anchors, supply materials and maintain offshore platforms. The arrangement of double aircraft and double propellers is often adopted. In order to maintain the stability of the heading, a dead-end rudder needs to be set between the two shafts. At the same time, due to the long de-flow section at the stern of the hull, it is difficult to arrange the piers. The rudder is also used to facilitate the arrangement of piers and support the weight of the ship's tail. The traditional rudder shape is a streamline symmetrical wing shape (horizontal section shape) to reduce drag. The cross section is usually rectangular or trapezoidal, with simple structure and convenient construction. However, the fluid dynamics performance of the traditional simple rudder shape st...
