Embodiment Construction

[0026] Referring to Figures 1 to 6, the present invention is a semi-submersible marine multifunctional engineering ship, which includes a hull and a crane installed on the hull.

[0027] The hull is a U-shaped semi-submersible hull structure, which is different from the hull of a general engineering ship. The U-shaped opening size of the U-shaped hull is determined after comprehensively considering the dimensions of different types of offshore drilling platforms. The water part of the U-shaped hull is the upper box 1, and the underwater part of the U-shaped hull is equipped with a streamlined underwater cushion 2. The underwater mat 2 is composed of a port side mat 21, a starboard side mat 22 and a horizontal mat 23 arranged longitudinally. The port side mat 21 and the starboard side mat 22 are connected by the transverse mat 23. A number of uprights 3 are installed between the upper box 1 and the underwater cushion 2. As shown in Figure 1, three uprights 3 are placed on one side ...

Abstract

The invention relates to a semi-submersible sea multifunctional engineering ship, comprising a hull, a crane, an underwater mat, a stanchion, an upper box body, a lifting beam, and pipe paving operation line arranged in module type. The hull is in U-shaped semi-submersible hull structure; the above-water part is the upper tank body and the under-water part is provided with a larboard mat and a starboard mat which are connected by a transverse mat; a plurality of stanchions are arranged between the upper tank body and the underwater mat. The cranes are two large full rotary cranes which can work independently, which are respectively arranged at the left side and the right side of an upper deck of the ship head of the U-shaped hull. The plurality of lifting beams is arranged at the opening of the U-shaped hull. The pipe paving operation line is arranged on the module of a main deck in the U-shaped hull trough. The invention has the advantages of implementing a plurality of operation working conditions of sea engineering with smart operation and strong adaptability and improving the application efficiency of the ship, generating great benefit, thus being first-choice equipment with wide application prospect in sea engineering ship field.

Description

Technical field [0001] The invention relates to an ocean engineering ship, in particular to a semi-submersible ocean crane engineering ship that can realize multiple functions. Background technique [0002] The 21st century is the century of ocean development. With the continuous development of offshore oil, the demand for offshore engineering ships continues to increase. At the same time, newer and higher requirements are put forward for offshore engineering technology and equipment. Therefore, there is an urgent need for development that can meet the requirements of ocean operations. The lifting engineering ship to meet the needs of the ever-developing ocean engineering. [0003] At present, the number of engineering ships engaged in offshore operations in the world is limited, generally having only a single function and high manufacturing costs. In order to consider its economic benefits, investors are only satisfied with manufacturing single-function engineering ships, which ...
