Problems solved by technology

[0005] The purpose of the present invention is mainly to solve the problems of difficult installation of the hydraulic pipes of the bow windlass during the construction process of super-large tankers, the schedule is tight, the pipes are not returned to the factory in time, and the time of oiling and even undocking of the windlass is affected, and a new bow windlass is provided. Installation and hoisting method of the hydraulic pipe of the windlass
The hoisting method of the present invention solves the problem of too long time, can shorten the construction time, improve the construction environment and reduce the construction risk factor

Embodiment Construction

[0020] Below we will further elaborate on the present invention in combination with the accompanying drawings and specific embodiments.

[0021] In the present invention, the hydraulic pump unit of the bow windlass is first set out and positioned according to the position and size on the ship in the infield, and then the design drawings are subdivided to make the hydraulic pipes of the bow windlass into an independent unit form, and the installation position of the hoist is confirmed by contacting the construction method , After the unit construction is completed, it will be hoisted as a whole when the general section is hoisted.

[0022] The hoisting method of the hydraulic pipe of the windlass at the bow of the ultra-large oil tanker of the present invention specifically includes the following steps:

[0023] The first step is production preparation: 1) Disassemble and refine the designed drawings before starting construction, and hand them over to the designer for con...

Abstract

The invention relates to a method for hoisting bow anchor gear hydraulic pipes of a supertanker. The method comprises the following steps of: firstly, lofting and positioning bow anchor gear hydraulic pump aggregate equipment in an inner field according to the position size on the supertanker; secondly, fractionizing a design drawing to manufacture the bow anchor gear hydraulic pipes into independent units, and contacting a working method to confirm a hoisting horse mounting position; and finally, after unit construction is finished, performing whole body hoisting during total section hoisting. By the method, the problems that after total section carrying, the hydraulic pipes are difficult to mount, are tight in progress, cannot return to a factory in time, and influence the oil throwing even undocking time of an anchor gear are solved, and the problems of poor construction environment and high danger coefficient are also solved.

Description

technical field [0001] The invention relates to the construction of an oil tanker, in particular to a method for installing a bow windlass hydraulic pipe during the construction of an ultra-large oil tanker. Background technique [0002] VLCC (Very Large Crude Carrier), that is, a very large crude oil carrier or a very large crude carrier. Due to the increasing progress of modern shipbuilding, the cycle between the ship's loading and undocking is getting tighter and tighter, and the time left for the hydraulic pipe installation and oiling of the bow windlass pump set is getting shorter and shorter. How to develop new technology to Speeding up the production schedule has become a new topic that needs to be solved without delay. [0003] Taking the construction of the VLCC H1202 as an example, as the first ship of VLCC 319K, we only have 22 days between the completion of the ship and its undocking. In the VLCC 319K, which is a very large tanker, the location of the hydrauli...
