Problems solved by technology

At the same time, such ships often need to install a large number of heavy-duty operating equipment, so the displacement is relatively large.
Therefore, this short, wide and fat ship type makes the initial stability height (GM) of this type of ship very large, and the rolling period is short, usually less than 10 seconds, so it swings violently in the waves, which limits the operation of the ship efficiency

Embodiment Construction

[0016] An implementation example of the present invention will be explained in detail below in conjunction with the accompanying drawings.

[0017] The invention is applicable to marine engineering ships such as lifting pipe-laying ships, drilling ships, workover ships, platform maintenance ships and the like. Such as figure 2 and image 3 A lifting pipe-laying vessel according to the embodiment of the present invention shown in , has a total length of 172.5 meters and a width of 35 meters.

[0018] figure 1 It is the hull form diagram of the present invention, and the ship form 1 has a thin water plane surface 2 . A vertical cylinder 3 is formed along the entire length of the ship by the waterline surface 2, which is the ship's side profile. The side profile of the ship is connected to the bottom of the ship through an arc-shaped bilge 4, preferably a circular arc-shaped bilge. The bottom of the ship includes a raised bottom 7 at the stern to improve the flow field in t...

Abstract

The invention discloses an ocean engineering ship type, and belongs to the field of ship design. The ocean engineering ship type comprises a quite thin draft water plane, a vertical cylindrical surface, perpendicular to the draft water plane, of the edge of the draft water plane forms a boardside hull line, the boardside hull line is connected to a hull bottom through an arc bilge area, the hull bottom comprises a tail-raised hull bottom located on the tail of a hull and a bulbous bow located on the head of the hull, the lower edge, located on the vertical cylindrical surface of the head of the hull, of the boardside hull line is connected with the bulbous bow, and the upper edge, located on the upper end of the vertical cylindrical surface of the head of the hull, of the boardside hull line is connected with an inclined flare curved surface. According to the technical scheme, the sea keeping performance and speediness performance of an ocean engineering ship are improved, fierce swing of the ship in waves is avoided, and operation efficiency of the ships is improved.

Description

technical field [0001] The invention belongs to the field of ship design and relates to an ocean engineering ship type. Background technique [0002] Offshore engineering ships, such as crane pipe-laying ships, are often designed to be relatively wide due to the need for a spacious operating deck area. And in order to reduce the wind area, the length of the ship can not be too long. Simultaneously, this type of ship often needs to be equipped with a large amount of heavy-duty operating equipment, so the displacement is relatively large. Therefore, this short, wide and fat ship type makes the initial stability height (GM) of this type of ship very large, and the rolling period is short, usually less than 10 seconds, so it swings violently in the waves, which limits the operation of the ship efficiency. [0003] Therefore, those skilled in the art are devoting themselves to developing an ocean engineering vessel with high seakeeping performance and low navigational resistan...
