Description
Technical field
The present invention relates to a kind of method of shipment of jacket piling bar, relate in particular to a kind of piling bar spreading of large-sized deep water jacket and the method for shipment, belong to the Offshore Engineering field.
Background technology
Along with China's marine petroleum development constantly to the striding forward of deep water field, the large-sized deep water jacket has obtained using more and more widely.At present, the domestic jacket depth of water has reached 216 meters.The piling bar length of deep water jacket is generally more than 100 meters, and adopts the whole section method of squeezing into the seabed, and weight can reach more than 500 ton.The piling bar of shallow water jacket usually is divided into several sections and carries out spreading and shipment, and behind the marine jacket launching, piling bar is squeezed into the seabed one by one by conduit.Generally speaking, the first paragraph piling bar is the longest and weight is larger, but weight adopts small-sized floating crane just can load onto ship generally in 100 tons.During the shipment of the piling bar of deep water jacket, because deep water jacket piling bar length is generally more than 100 meters, and weight reaches more than 500 tons, needs the special shipment passage of design to load onto ship.
The piling bar spreading of existing large-sized deep water jacket and the method for shipment, generally adopt following steps:
1, piling bar 1 segmentation in the tubulation workshop rolls, and piling bar 1 adopts steel plate materials to make.At first, steel plate is cut in the tubulation workshop, blanking and roll into several little pipeline sections (each little pipeline section that rolls into is generally less than 3 meters);
2, adopt overhead traveling crane with several tubule section handlings to piling bar spreading automatic job line, carry out more than the integral solder spreading to 100 meter of piling bar;
3, after the piling bar spreading was finished, the automatic job line was transported to outside the workshop piling bar storage area with piling bar and deposits;
When 4, loading onto ship, the employing pile follower is transported to piling bar near the harbour;
5, then, adopt large-scale floating crane that piling bar is lifted shipment.
Mainly there are following shortcoming in above-mentioned this piling bar spreading and shipment method:
1. need the special shipment passage of design: namely: piling bar spreading and transportation manufacturing line, pile follower and special piling bar storage area, investment is large, and the place demand is large;
2. because the Deep Water Jacket Fabrication cycle is long, and some jackets only production cycle just surpass 1 year, and the Production requirement of piling bar is relatively very little, this causes the waste in equipment and place just so that custom-designed shipment passage is in idle state for a long time;
3. because deep water jacket piling bar weight is large, generally all need large-scale floating crane to load onto ship, and domestic utilizable large-scale floating crane resource pretty nervous;
4. the appropriate litigation fees that adopts large-scale floating crane to load onto ship is high;
5. the deep water jacket piling bar is very long, and the stressing conditions of piling bar is bad during large-scale floating crane shipment;
6. the piling bar shipment cycle is subjected to the impact of large-scale floating crane very large.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that existing shipment method exists, and the method that the piling bar that a kind of improved large-sized deep water jacket is provided is loaded onto ship, the investment that it can be saved the piling bar spreading and transport manufacturing line, pile follower has reduced the inner space, workshop; Simultaneously, saved the design of special piling bar storage area, the place demand is little.Solve the problem of piling bar segmentation transportation and integral solder spreading outside the workshop, reduced large-scale floating crane resource anxiety to the impact of piling bar shipment, reduced greatly the expense of shipment, improved shipment efficient.
The objective of the invention is to be realized by following technical scheme.
A kind of piling bar spreading of large-sized deep water jacket and the method for shipment may further comprise the steps:
The first step, rolls and the segmentation spreading segmentation of piling bar:
With steel plate cutting stock and roll into several rouleau tubulation sections in the tubulation workshop, it is characterized in that: every piling bar integral body is comprised of three segmentations, and several rouleau tubulation sections are welded 1/3 segmentation that spreading becomes whole piling bar 1;
Second step, the whole spreading of piling bar:
Adopting transport trolley that three segmentations of piling bar are transported near the appointment place the harbour and be placed on the positioner, carry out the integral solder spreading of piling bar 1, is whole piling bar with three segmentations welding spreadings of piling bar;
The 3rd step, the stacking of piling bar:
After the whole spreading of piling bar is finished, adopt two large-scale crawler cranes that whole piling bar is moved to the stacking zone by root and deposit;
The 4th step, the lifting of piling bar:
At the rear, wharf apron, arrange two large-scale crawler cranes, each large-scale crawler crane main hook is connected with piling bar by hanging belt, and two large-scale crawler cranes cooperatively interact and carry out the piling bar ship-loading operation;
The 5th step: piling bar aboard ship rolls:
Roll the dress suspension centre what hull arranged piling bar, after piling bar lifted to the hull, the shackle by steel rope one end was connected with suspension centre, and utilizes the auxiliary hook of two large-scale crawler cranes upwards to promote, and makes the rolling of piling bar on hull;
The 6th step: piling bar is fixing aboard ship:
Piling bar lift to hull and roll in place after, adopt steel structure frame to carry out the fixing of piling bar.
Described the 3rd step, the stacking of piling bar: stack successively piling bar according to layout and the shipping sequence of piling bar on hull, that is: successively pile up by order from top to bottom.
The lifting ship-loading operation of described the 4th step piling bar: fill first a side piling bar, then turn the hull direction and refill the opposite side piling bar.
In described the 4th step, the type of attachment of each large-scale crawler crane main hook and piling bar is: the hanging belt pocket draws piling bar.
In described the 6th step, steel structure frame is for adopting I-beam section, steel pipe or steel plate to make, and fixed form is: steel structure frame is weldingly fixed on the hull.
Described the 5th step arranges a temporary supporting at hull, piling bar can be rolled at hull put in place.
Beneficial effect of the present invention: the investment that the present invention can save the piling bar spreading and transport manufacturing line, pile follower, reduced the inner space, workshop; Simultaneously, saved the design of special piling bar storage area, the place demand is little.Solve the problem of piling bar segmentation transportation and integral solder spreading outside the workshop, reduced large-scale floating crane resource anxiety to the impact of piling bar shipment, reduced greatly the expense of shipment, improved shipment efficient.
