Embodiment Construction

[0022] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0023] Such as figure 1 As shown, this embodiment includes the following steps:

[0024] The first step is to cut off the bow of the oil tanker to be transformed, add a modified bow that meets the lifting operation and speed requirements, and fix the crane base and anti-collision bulkhead on the transformed bow.

[0025] The modified bow is a multi-layer platform deck structure used as the basis for the rotatable support of the crane base, and is equipped with a fore peak tank, a bow pump room, a chain locker room and a side thruster room.

[0026] The anti-collision bulkhead is a watertight bulkhead, and the wat...

Abstract

The invention discloses a method in the technical field of shipping hoisting, in particular to a modification method of a large-scale crane ship based on a large-scale oil tanker with longer parallel middle body. The floating force is increased through assembling a modified ship bow and box-shaped floating bodies at the two sides of a ship body, and the modification of the large-scale crane ship is realized through replacing a main deck by a beamless flat deck, arranging a crane and reinforcing the interior of the ship body. The invention meets the requirement on controlling the floating state during the working of the large-scale crane ship, improves the total longitudinal strength of the shipping through the arrangement of a modified deck and a centerline bulkhead, and meets the requirement on local intensity through the design of a barrel-shaped honeycomb structure. Rapid dispensation of ballast water during working is realized through the optimized design of a ballast tank and the arrangement of a ballast water pump; the work performance and the control performance are improved through configuring an auxiliary machine, an anchoring machine, a winch and a bow thruster so as to realize that the large-scale oil tanker is modified into the large-scale crane ship on the basis of little modification, therefore, the time and the cost are saved; and the method has larger economic effect and finds a new way for developing old ships.

Description

technical field [0001] The invention relates to a method in the technical field of ship lifting, in particular to a method for refitting a large lifting ship based on a large oil tanker with a long parallel center body. Background technique [0002] Large oil tankers generally adopt a single-layer continuous longitudinal deck, with less equipment on the deck and large deck space; the stern type is adopted, and the engine room is located at the stern; the main equipment of the cargo oil pump is also located at the stern; the bow and stern are linear to meet the speed. Requirements: There is a larger parallel center body, a larger cargo oil tank and a double bottom, and the structure is simple and strong; a stern deckhouse is provided. [0003] Large-scale crane ships are equipped with huge lifting equipment and supporting structures, and the structures need to be partially strengthened at relevant positions; the concentrated load is large during operation, and the requirement...
