Embodiment Construction

[0028] The invention provides a new method and equipment for adjusting the angle of the stinger, and its specific operation method includes the following steps:

[0029] (1) Connect the reinforced structure equipped with pulley blocks, the truss structure and the connecting rod structure with lifting points that can rotate in both directions. see Figure 1-Figure 5 .

[0030] (2) Fix the structural hinge installed in (1) to the stern (bow). see Image 6 .

[0031] (3) Connect the reinforced structure equipped with the pulley block with the pulley block of the support structure at the end of the hull with cables, see Image 6 .

[0032] (4) Hoist the stinger and fix the stinger to the stern (bow). Connect the connecting rod structure with the working lifting point on the stinger. see Figure 7 .

[0033] (5) After the connection of the entire structure is completed, according to the needs of the pipe laying operation, the cables between the pulley blocks can be loosene...

Abstract

The invention relates to a new method for regulating an angle of a stinger and a device thereof. The method comprises the following steps: (1) arranging a strengthening structure equipped with a fixed pulley blocks at a stern (or bow) to be connected with a pulley block on a support structure at an end of a ship; (2) arranging a truss structure to change width; (3) arranging a connection rod at the end of the truss structure to be connected with the stinger; (4) connecting the strengthening structure equipped with the fixed pulley block with the truss structure as well as the truss structure with the connection rod by a connection sustained center which can rotate in two directions; and (5) loosening and straining a cable connecting the pulley blocks by control of a winch to drive the structure so as to change the angle of the stinger and meet mounting and pipelaying requirements. New device is used to completely separate mounting of the pulley blocks from the stinger structure without requiring the same width of the pulley block on the stinger and the pulley block at the end of the ship, and the pulley blocks are prevented from being soaked in water for a long time, thus the applicability is wider.

Description

[0001] Invention name: A new method and equipment for adjusting the angle of the stinger Background technique [0002] Fixed stinger pipe laying is a common method for laying submarine oil pipelines in the world at present. This method is convenient for construction, saves investment and has the shortest construction period. In order to make the pipe laying work go on smoothly, the adjustment of the angle of the stinger is an essential link. The method usually adopted when adjusting the angle of the stinger at present is to install the pulley block on the stinger and the hull end support structure, and control the purpose of controlling the angle of the stinger by controlling the loosening and tensioning of the cables between the pulley blocks. The existing method is complicated to operate, requiring the pulley block on the stinger and the pulley block on the hull end support structure to be at the same width, and the rope-threading operation between the pulley blocks is requi...
