Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0018] The present invention transforms an unmanned barge into a slewing lifting barge, which mainly includes a column-type slewing lifting device and a main hull of the barge, and functional cabins such as a generator cabin and a control room are arranged inside the main hull and on the main deck . The specific modification methods are as follows, and it should be noted that the sequence of steps included in the following modification methods is not limited, and can be reasonably arranged according to the actual situation.

[0019] 1. Transformation of the hull of the unmanned barge:

[0020] Since the slewing crane ship has high requirements on stability whe...

Abstract

The invention provides a revolving crane ship renovation method based on an unmanned barge and a crane barge. The renovation method comprises the following steps: a step of renovating a body of the unmanned barge: a stern additional structure, a port additional structure and a starboard additional structure are respectively added on a stern, a port and a starboard of the body of the barge, and an original depth of the body of the barge is increased to form a main body of a crane ship; a step of adding a stand column type full-revolving crane: the crane comprises a crane base and a boom, wherein the crane base is arranged on the stern additional structure, and the boom can rotate surrounding the crane base; and a step of adding a ballast system: ballast tanks and void compartments are added in a cabin of the body of the barge, the port additional structure, the starboard additional structure and the stern additional structure to form the ballast system.

Description

technical field [0001] The invention relates to a transformation method in the technical field of ship lifting, in particular to a method for transforming an unmanned barge into a slewing crane ship. Background technique [0002] With the rapid development of offshore oil development, large-scale offshore engineering construction, coastal wind power equipment installation and shipwreck rescue, as a commonly used engineering ship, the demand for large lifting ships is also increasing rapidly. A slewing crane vessel features massive lifting equipment, load adjustment equipment and support structures. The boom structure is super long and heavy, which requires strict structure and stability; ballast water needs to be quickly and effectively deployed during the lifting process; the hull needs to be partially reinforced at relevant positions; the concentrated load is large during operation, which affects the overall longitudinal strength. High standard. These factors lead to the...
