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
The present invention relates to tanker construction, be related specifically to the installation method of ultra large crude carrier bow windlass hydraulic pipe in manufacture process.
Background technology
VLCC (Very Large Crude Carrier), i.e. very large crude-oil carrier or ultra large crude carrier.Due to the quickening day by day of Modern Shipbuilding progress, it is more and more tighter that full ship carries through and between undocking cycle, leaving bow windlass pump group hydraulic pipe for, to install, throw time of oil shorter and shorter, how to carry out new process and carry out enhance production progress and just become the very urgent new problem that need solve.
With model be H1202 ultra large crude carrier be constructed to example, as the leading ship of VLCC 319K, our 22 day time only left for by full ship between penetrating into and undocking.As in the VLCC 319K of ultra large crude carrier, its bow windlass hydraulic pipe location comparison is important, which includes many existing school pipes.Only the normal period of now school pipe making is longer, according to current manufacture process, generally adopts: setting-out-existing school-pattern-tubulation-freeze-polish-submission-pump pressure of making film submit to-send the steps such as surface treatment.Whole manufacturing process gets off to need altogether 20 day time, before this does not also comprise the location-submission weldering of windlass pump group pedestal-freeze-polish-paint-pump group installation equal time.
In recent years, planting cross-operation to shorten multiplex (MUX) in shipbuilding period, minimizing cabin, reduce labor intensity in many shipbuilding yards, and improves installation and handling efficiency, all on the basis of piping layout, applies modularization assembling new process.Segmentation manufacture and the complete cross section of the ripe utilization of such as VLCC carry technique.The pressure undocked is about under the pressure of leading ship, above-mentioned so be also the thing of being compelled to do by the time compress of the making and installation process of bow windlass pump group hydraulic pipe.
Summary of the invention
Object of the present invention mainly solve ultra large crude carrier bow windlass hydraulic pipe in manufacture process install difficult, progress tight, pipe return factory not in time, affect windlass and throws oil and even to undock the problem of time, the installation of a kind of new bow windlass hydraulic pipe and hanging method are provided.Hanging method of the present invention solves the problem of overlong time, can shorten the engineering time, improves construction environment and reduces construction risk coefficient.

5th step, contact engineering method personnel confirm to hang the installation site of horse on unit, and carry out hanging the construction of horse on unit, and construction is to whole unit completion to Liftable state;
6th step, treats that the bow complete cross section general assembly of ultra large crude carrier completes, then is lifted on described bow complete cross section by bow windlass hydraulic pipe whole unit.
In the hanging method of ultra large crude carrier bow windlass hydraulic pipe of the present invention, fittings in the described first step comprises anchor winch Hydraulic Pump group pedestal, service platform, air cooler platform, angle bar, channel-section steel and hangs horse, described pipe fittings comprises U-shaped horse, pipe bracket, pad and O shape circle, described tubing comprises existing school pipe flange and angle bar, and described valve member includes triple valve, shutoff valve and hydraulic pipe valve member.
In the hanging method of ultra large crude carrier bow windlass hydraulic pipe of the present invention, in described 3rd step, to stretch out installation from bow windlass Hydraulic Pump group and pedestal thereof by figure paper size when becoming unit by described assembling parts.
In the hanging method of ultra large crude carrier bow windlass hydraulic pipe of the present invention, described hang the mode that horse adopts electric welding to freeze and be arranged on the hard shelves of piping support, cut off after integrated units has lifted and described hang horse.
Based on technique scheme, method of the present invention achieves following technique effect in the manufacture and lifting of ultra large crude carrier bow windlass hydraulic pipe:
Method of the present invention first ultra large crude carrier bow windlass pump group hydraulic pipe and miscellaneous part overall package is become an integrated units, and then after whole unit is lifted into boats and ships bow complete cross section and boatswain's store, the existing school pipe so only needing making 4 and top section to close up, and the oil charging pipe at the places such as fuel tank directly can carry out the first step throws oil, solve complete cross section carry after hydraulic pipe install difficult, progress tight, pipe returns factory's problem not in time.Method of the present invention can also substantially improve construction environment, more importantly shortens the depressed place phase, for the large node completing ship building plays a significantly greater role on time.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram being combined into overall bow windlass hydraulic pipe unit.
Detailed description of the invention
we further elaborate the present invention with specific embodiment by reference to the accompanying drawings below.
The present invention be first in internal field by bow windlass Hydraulic Pump group equipment by the position dimension setting-out on ship, then segment design paper and bow windlass hydraulic pipe is made into independently unit form, and contact engineering method confirm hang horse installation site, unit construction after integral hoisting when complete cross section lifts.
The hanging method of ultra large crude carrier bow windlass hydraulic pipe of the present invention specifically includes following steps:
