Description
Technical field
The present invention relates to a kind of novel half latent ships that transport, particularly relate to a kind of knockdown ships that transport and method of work thereof of partly diving, belong to half latent ships that transport technical field。
Background technology
Half cargo ship of diving is a kind of to have huge deck-cargo space, has part dive ability, can transport and load and unload the special engineered ship of overlength, overweight and inseparable super large special cargo, particularly ocean engineering platform。Its hull overwhelming majority when handling operation can be dived beneath the water, and is then in normal load draught state when navigating by water。Semi-submerged ship utilizes the ballasting system of self, makes the cargo deck dive of hull submerge in water, and loading of entertaining is dragged to after above deck, makes hull float again through ballasting system, carrier is lifted out the water surface and is solid；After carrier transports to destination, sinking with carrier, solve open system solid, after loading of entertaining floats and separates with semi-submerged ship, semi-submerged ship is withdrawn and floats voluntarily, and namely hauling operation has accused。The semi-submerged ship important equipment that still salvage engineering is indispensable under water, coordinates large-scale crane ship to carry out lifting salvaging, has the advantages such as more rapid, safe than conventional raising with salvage pontoons。
But the half dive operation diving cargo ship, is the high operation process of risk that sea-freight circle generally acknowledges。Minority has the company of half latent ships that transport in the world at present, even if having done a large amount of checking computations in advance, also cannot assure the perfectly safe of job safety。Its risk occurs mainly with, and main deck soaks in an instant, and Water Plane reduces suddenly, thus brings the stability bust of boats and ships。Therefore this kind of operation is often after having paid great number insurance premium, selects to carry out operation under splendid meteorological condition。Even so, also still occurred semi-submerged ship before this in dive operation process, the serious accident toppled because of above-mentioned reason and sink。
Therefore, half current latent cargo ship, it is common to there is the problem of stability and reserve buoyancy deficiency in dive process。Within the short time of main deck immersion, due to strongly reducing and the dual function of wave motion on deck plane of Water Plane, cause that the stability of boats and ships sharply worsens。Simultaneously because the ballast pump delivery of half latent cargo ship is very big, in dive process, any operational error all can cause violent the rocking of boats and ships, makes follow-up dive operation be difficult to carry out。
Additionally, half current latent cargo ship is often all based on specific goods and is customized, cargo collection flexibility ratio is relatively low, and economy is poor。In turn result in freight charges to remain high, constrain the process of ocean development cause in a way。
For problem above, currently common method, one is arrange some buoyancy tanks at afterbody, to provide extra Water Plane in the process of dive, thus providing buoyancy reserve for full ship, improves stability。Two is the richness by increasing foreship line style, reaches to increase the purpose of Area of Water Plan, and then improves full ship stability。There is techniques below problem in this countermeasure:
Although 1, afterbody buoyancy tank can increase water plane area, but compares the Area of Water Plan anticlimax produced after main deck soaks, ratio is still only small, so the effect that can play is extremely limited。If additionally, buoyancy tank yardstick is excessive, can have adverse effect on again for handling goods；
Even if 2, foreship line style flare, the effect that the Water Plane that it brings increases is also very limited。Meanwhile, if stem line style is excessively plentiful, resistance can be increased during navigation greatly, and then reduce the speed of a ship or plane, unfavorable simultaneously for operation of casting anchor；
3, half currently existing latent cargo ship, is all the piece rigid hull adopted, mostly adopts fore-body to add (including building place, machinery space) layout pattern of rear portion loading platform (mainly including ballast tank) formula。Its yardstick is all carry out custom-made by size according to extra large work goods yardstick set in advance, and therefore the cargo collection flexibility ratio of boats and ships is relatively low, and the transport task being able to carry out every year is extremely limited, is also a kind of wasting of resources to a certain extent；
Above-mentioned unfavorable factor considerably increases the operations risks of shipowner, also leads to insurance company simultaneously and insurance premium to this type of boats and ships is greatly improved。Simultaneously as customization is excessively strong, flexibility ratio is relatively low, increases the early investment cost of shipowner and the cost of upkeep in later stage
Summary of the invention
The technical issues that need to address of the present invention are:
Half current latent cargo ship, it is common to there is the problem of stability and reserve buoyancy deficiency in dive process, existing counter-measure can bring again various unfavorable factor；Meanwhile, half current latent cargo ship is often all based on specific goods and is customized, and cargo collection flexibility ratio is relatively low, and economy is poor, in turn results in freight charges and remains high, constrains the process of ocean development cause in a way。
