Description
Technical field
This utility model is related to a kind of ship and drilling platforms floating aid system.
Background technology
Prosperity with world's shipbuilding industry and the development of offshore oil cause, the construction tonnage of large ship is increasing,
As various bulk freighters, container ship etc., to meet the demand of bigger transport capacity, for the drilling platforms of marine petroleum development
Application is also increasing, including various jack-up units, semisubmersible platform, floating platform etc..
The deadweight that ship 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 25000 tons semi-submersible type oil drilling platform etc., and the volume of hull is huger, up to more than 200 meters, width
Reach more than 80 meter, by the way of the building of these ship platform substantially adopts construction in dock, sail to sufferance quay or boat from dock
Road waters, carries out installation and test of next step etc..Allowed that construction ability is limited and old-fashioned dock structure in itself by dock
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 the depth of water in navigation channel or dock, thus lead to ship platform to bottom out or hull bottom with water-bed cannot sail less than safe distance or
Reach appointed place through shallow waters, have impact on the progress sailed and be further delivered for use of ship platform, some
Also ship and sat stranded, hull bottom with water-bed barrier collision thus damaging the painful accident of hull in shipyard.
The method of such issues that solution has four kinds of methods:
Depth is dug by equipment such as dredgers in navigation channel by the first method using digging deep stream, reaches the navigation of needs
Depth, this method construction period is especially long, expense is especially high, especially when carrying out digging deep to neritic province domain, by water-bed geology
The restriction of structure is larger, when running into large-scale hard reef, needs to carry out underwater reef explosion, and underwater cleaning cubic meter of stone amount is big, thus making
Become the safety of construction, Cycle Length to control and costly equivalent risk, its advantage is to put things right once and for all, after once digging depth, maintain the cycle
Long.
The method using reducing ship own wt for the second method, only installs after ship platform construction thematic structure
A part of equipment, reducing the hull platform weight sailed, thus reducing draft, reaching the waters of the enough depth of water after sailing
It is further continued for carrying out installation and the debugging efforts in later stage, thus causes the secondary displacement of build the side, some mounting process are 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 shifting, and installation and debugging progress is more limited
System, thus leading to 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, realizes the big purpose of little material.
The third method is to produce buoyancy reduction draft by increasing steel buoyancy tank on platform, thus crossing shallow water
Region, this method is primarily adapted for use in sailing or transporting of drilling platforms.In practice, increase the expense phase building steel buoyancy tank
Work as costliness, the cycle installed and remove is long, spend in time in auxiliary equipment such as large-scale floating crane and costly, early stage is necessary
Carry out detailed design, the design ＆ check workload of strength and stability is big, to therein be fixedly connected, assembling and disassembling more numerous
Trivial, the complex structure of steel buoyancy tank casing, the welding processing cycle is long, moreover buoyancy tank dead weight is larger, in dock or harbour peace
Dress difficulty is big, crucial its provide help buoyancy also extremely limited, when needing large-tonnage, internal structure stress is complicated, increased
The risk of deformation fracture, simultaneously because steel buoyancy tank be steel plate welding body it is desirable to have under water higher bubble-tight simultaneously
Its case hardness height, it is impossible to directly contact with each other with hull, can only be welded on the corresponding position of hull, this results in dismounting side
Face increased operation easier, and especially cutting further increases the operation restriction of diver under water, and steel buoyancy tank once encounters hull,
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 have good advantage substantially.
4th kind of method is to carry partly 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, and platform is slid onto after partly latent barge is fixed and can sail, and its maximum shortcoming is fortune
Defeated cost highest, needs to arrange sailing date using partly latent barge, and the dynamic system in partly latent barge bottom, when navigation channel is very shallow can not
Meet partly latent barge navigation draft when, this method is equally invalid, the risk navigated by water by force can lead to barge and
Ship platform jointly stranded.
Can be seen that from above four kinds of methods respectively has pluses and minuses, mainly to the construction cost of project, cycle and assembling and disassembling
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
Key is to increase the buoyancy of hull, reduces the draft of hull, thus meeting the depth requirements that sail in navigation channel.
Content of the invention
