Embodiment Construction

[0022] A method for installing a stinger on a 400-ton lifting pipe-laying vessel on water, comprising the steps of:

[0023] 1) Preparatory work before the water installation of the stinger 1: First, complete the overall assembly of the stinger 1; then, hang the fixed pulley 13, the pin 8, the luffing wire rope 20, the shackle 21, etc.; at the same time, prepare the equipment and facilities including: bearing Floating barge 14, skid 15, weight 17, first chain hoist 6, second chain hoist 25, third chain hoist 28, suspender 27 and wire rope 5; finally, complete the electric motor on the top surface of the hull corridor. The double-drum mooring winch 22 and the luffing winch 23 are debugged, and at the same time record the draft value of the port side of the stern, the draft value of the starboard side of the stern, the distance from the center of the shaft hole of the stern pin seat 10 to the water surface when the ship is stationary;

[0024] Such as figure 1 figure 2 As sho...

Abstract

The invention belongs to the technical field of shipbuilding and particularly provides an on-water mounting method for a stinger on a pipe-laying ship with the lifting capacity of 400 tons. The on-water mounting method comprises the following steps: conducing preparatory work before the stinger is mounted on water; connecting the hinge pin of the stinger to a hinge pin seat at the stern of a ship body, and hauling the jib lubbing mechanism of the stinger. The on-water mounting method can utilize the existing equipment and facilities of a shipyard, bring the own conditions of the pipe-laying ship in to play, make full use of resources, and further promote the competitiveness of the shipyard. Through the adoption the on-water mounting method, expense spent on renting a floating crane is saved, the shipbuilding cost is lowered, and the on-water mounting work of the stinger can be completed efficiently and safely.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for installing a stigma on a 400-ton lifting pipe-laying ship on water. Background technique [0002] The stinger is one of the important equipment in the submarine pipeline laying when the crane pipe-laying ship is working. It is mainly used to support the pipeline when it is lowered from the stern to prevent excessive bending of the pipeline. There is a set of hinges at the stern of the 400-ton crane pipe-laying ship The variable-amplitude stinger is connected to the stern of the hull through the luffing mechanism and the hinge mechanism to the A-frame and the pin seat on the hull. The weight of the stinger including accessories is about 100 tons, and the size is: long It is about 39.5 meters wide, about 4.22 meters wide, and about 4.26 meters high. As an important production node, the installation stage of the stinger will affect the entire ship construction cyc...
