Description
Technical field
The present invention relates to a kind of boats and ships and drilling platforms floating aid system and construction method.
Background technology
Along with prosperity and the development of offshore oil cause of world's shipbuilding industry, the construction tonnage of large ship is increasing,
Such as various bulk freighters, container ship etc., to meet the demand of bigger transport capacity, for the drilling platforms of marine petroleum development
Apply the most increasing, including various jack-up units, semisubmersible platform, floating platform etc..
The deadweight that boats and ships and drilling platforms (hereinafter referred to as ship platform) are built is gradually increased, such as the packaging of ten tons
Case ship, gross weight reach the semi-submersible type oil drilling platform etc. of 25000 tons, and the volume of hull is huger, up to more than 200 meters, width
Reach more than 80 meter, the mode building the basic interior construction of employing dock of these ship platform, sail to sufferance quay or boat from dock
Waters, road, carries out next step installation and test etc..Allowed that construction ability is limited and old-fashioned dock structure by dock itself
The hysteresis quality impact of design, is frequently encountered due to ship platform draft in the construction of ship platform with during sailing
More than navigation channel or the depth of water of dock, thus cause ship platform to bottom out or hull bottom with water-bed cannot sail less than safe distance or
Arrive appointed place through shallow waters, have impact on the progress sailed and be further delivered for use of ship platform, at some
Shipyard also occurred that boats and ships were sat stranded, hull bottom and with water-bed barrier collision thus damaged the painful accident of hull.
The method such issues that of solution has four kinds of methods:
The first uses the method digging deep stream, i.e. digs deeply by equipment such as dredgers by navigation channel, reaches the navigation degree of depth needed,
This method construction period is long especially, expense is the highest, especially when digging deep to neritic province domain, by water-bed geologic structure
Limiting relatively big, when running into large-scale hard reef, need to carry out underwater reef explosion, underwater cleaning cubic meter of stone amount is big, thus causes construction
Safety, Cycle Length control and costly equivalent risk, its advantage is once and for all, once dig deep after maintain the cycle long.
Second method uses the method reducing boats and ships own wt, i.e. ship platform only to install after building thematic structure
A part of equipment, reduces the hull platform weight sailed, thus reduces draft, arrive the waters of the enough depth of water after sailing
Being further continued for carrying out installation and the debugging efforts in later stage, thus cause the secondary displacement of build the side, some mounting process is subject to
The impact that shifts to place and become more loaded down with trivial details, the installation of some equipment is also carried out displacement, and installation and debugging progress is more limited
System, thus cause the lengthening of construction period and the increase of mounting cost, unfavorable to the construction benefit improving project.This method
Advantage is that marina can also build big ship, it is achieved the purpose that little material is big.
The third method is by increasing steel buoyancy tank generation buoyancy reduction draft on platform, thus crosses shallow water
Region, this method is primarily adapted for use in sailing or transporting of drilling platforms.In practice, the expense phase of construction steel buoyancy tank is increased
Working as costliness, the cycle installed and remove is long, spends in auxiliary equipment such as the time on large-scale floating crane and costly, and early stage is necessary
Carrying out detailed design, the design & check workload of strength and stability is big, more numerous to fixing connection therein, assembling and disassembling
Trivial, the structure of steel buoyancy tank casing is complicated, and the welding processing cycle is long, moreover buoyancy tank dead weight is relatively big, pacifies at dock or harbour
Dress difficulty is big, crucial its provide help buoyancy the most extremely limited, when needing large-tonnage, internal structure stress is complicated, adds
The risk of deformation fracture, simultaneously because steel buoyancy tank is Plate Welding body, it is desirable to have under water higher bubble-tight while
Its case hardness is high, it is impossible to directly contacting with each other with hull, can only be welded on the corresponding position of hull, this results in dismounting side
Face adds operation easier, and cutting further increases the operation restriction of diver the most under water, and hull once encountered by steel buoyancy tank,
Cause outer peeling paint or ship skin stress deformation, it will cause the product of the problems such as unexpected additional maintenance cycle and expense
Raw.This method does not the most have good advantage.
4th kind of method is to carry half latent barge to sail, and this method is suitable for the transport of the drilling platforms of distance, and it is excellent
Point is simple to operate safe and reliable, is slid onto by platform after half latent barge is fixed and can sail, and the shortcoming of its maximum is fortune
Defeated cost is the highest, uses half latent barge to need to arrange sailing date, and dynamic system bottom half latent barge, when navigation channel is the most shallow can not
When meeting the draft of half latent barge navigation, this method is invalid equally, the risk navigated by water by force can cause barge and
Ship platform the most stranded.
From above four kinds of methods it can be seen that be respectively arranged with pluses and minuses, mainly construction cost, cycle and the assembling and disassembling to project
Operation easier effect different.In conjunction with above-mentioned four kinds of methods, from the root-cause analysis demand of problem, solve what shallow water sailed
It is crucial that increase the buoyancy of hull, reduce the draft of hull, thus meet the depth requirements that sails in navigation channel.

Continuing dock is carried out water filling, water level reaches to help the depth of water of floating conditions dictate；
Step 4, uses power drive or towage mode to drive to ship along navigation channel specify waters, and this waters should meet dismounting and help floating
Draft after system, then hull casts anchor, and to helping floating cell cube slowly to exit, deflation sequences is according to first four
Each is helped floating cell cube slowly to exit by the symmetric mode in the middle of behind angle simultaneously, and the drinking water that hull slowly sinks to reaching work is deep
Degree；
Step 5, after Flexible pontoon venting, auxiliary float makes Flexible pontoon be suspended in water, removes and is helped floating unit
The auxiliary suspender belt and the pipeline of all connections on body top, each helps floating cell cube to reach free floating condition, departing from the bottom of hull
Portion, is finally recovered to land and carries out inspection and maintenance.
8. boats and ships as claimed in claim 1 and the construction method of drilling platforms floating aid system, it is characterised in that include following
Step:
Step 1, assembles and helps floating cell cube, then uses towboat mode, and floating cell cube will be helped under water longitudinally to pull hull bottom into, left
Right floating drum lays respectively at the left and right sides of hull；
Step 2, is arranged into deck in ship structure or other convenient position controlled by electrical control panel assembly, and one by one to helping floating unit
Body is controlled debugging；
Step 3, tentatively inflates floating drum, helps floating cell cube to enter each according to the symmetric mode in the middle of behind first corner simultaneously
Row slowly inflation, when the depth of water reaches floating drum submergence about 20%, connects auxiliary suspender belt and the joining shackle on top, and floating drum is tight
Tight is bundled on hull；
Step 4, carries out second time slowly inflation by air-charging and air-discharging system to helped floating cell cube, according in the middle of behind first corner
Symmetric mode, hull will float in the process, reach the draft of towage；When intrinsic pressure reach operating pressure require time, stop
Only inflation, stably helps floating state；Again fasten each help floating cell cube top assist suspender belt temporarily, reach tension, help
Floating state balance is stable；
Step 5, uses power drive or towage mode to drive to ship along navigation channel specify waters, and this waters should meet dismounting and help floating
Draft after system, then hull casts anchor, and to helping floating cell cube slowly to exit, deflation sequences is according to first four
Each is helped floating cell cube slowly to exit by the symmetric mode in the middle of behind angle simultaneously, and the drinking water that hull slowly sinks to reaching work is deep
Degree；
Step 6, after Flexible pontoon venting, auxiliary float makes Flexible pontoon be suspended in water, removes and is helped floating unit
The auxiliary suspender belt and the pipeline of all connections on body top, each helps floating cell cube to reach free floating condition, departing from the bottom of hull
Portion, is finally recovered to land and carries out inspection and maintenance.
