Embodiment Construction

[0024] In order to make the present invention more obvious and understandable, the preferred embodiments are described in detail as follows in conjunction with the accompanying drawings:

[0025] Such as Figure 1-6 As shown, the present invention provides a device for reducing the resistance of the moon pool of an ocean engineering ship. The hull is provided with a moon pool structure 3 that runs through the hull in a vertical direction and is used to connect internal and external sea water; the moon pool structure 3 is provided with a reducing The device for the resistance of the moon pool of an ocean engineering ship includes a moon pool attachment structure 4 and a wave-dissipating plate 31; A wave breaking plate 31 is provided on one side of the ship wall. Moon pool appendage structure 4 is set as the arc structure that moon pool structure 3 is provided with on the side ship wall near the stern. The arc-shaped structure includes an arc-shaped protruding portion protrudi...

Abstract

The invention relates to a device for reducing moon pool resistance of an ocean engineering ship, and belongs to the technical field of ocean engineering ships. The moon pool structure is provided with a device for reducing the moon pool resistance of an ocean engineering ship and comprises a moon pool appendage structure and a wave absorbing plate. The moon pool appendage structure is arranged onthe ship wall of the side, close to a stern, of the moon pool structure, and the wave absorbing plate is arranged on the ship wall of the side, close to the bow, of the moon pool structure. Waves formed by the moon pool bulkhead structure close to one end of the prow and waves formed by the appendage structure are mutually counteracted in the navigation process of the ship, so that wave energy ina moon pool area is reduced, and resistance in the navigation process is reduced; meanwhile, a wave absorbing plate structure is additionally arranged at the other end of the moon pool to absorb thewater flow at the other end in the ship sailing process, so that wave surging accumulation is avoided. The practicability is realized; the resistance, especially the wave-making resistance, of the moon pool area is reduced; the wave height of waves is reduced, and the risk of upwelling slamming is reduced; shipbuilding materials are saved, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a device for reducing the resistance of a moon pool of an ocean engineering ship, and belongs to the technical field of the ocean engineering ship. Background technique [0002] In recent years, with the improvement of the country's special marine equipment and technology and the development of marine engineering projects, as scientific research projects have advanced to deep sea areas, more and more technical problems have gradually limited the further development of scientific research projects. Among them, for ships operating in deep sea, the moon pool structure is a very conventional and indispensable structural type; in the field of ships and ocean engineering, according to ships and marine structures such as drilling ships, pipe-laying According to the operational or functional requirements, a moon pool structure will be arranged on the hull vertically through the hull, with a free liquid surface in the cavity and a conne...
