Description
Technical field
The present invention relates to polar ship technical field, specially a kind of Novel icebreaker bow structure and icebreaking method.
Background technique
Polar region is the strategic space that countries in the world future development must strive.Currently, international polar region affairs are occurring deeply
Variation, Arctic enter the preparatory stage of development and utilization, and Antarctic region springs up as undercurrent around the competition of development of resources, and weather becomes
The international competition of the great science frontier research such as change, Environment Change, universe and origin of life obviously aggravates.
Many potential resources are contained in polar region.It is research gas for example, containing climatic information abundant in the glacier of the South Pole
Wait an extraordinary sample of variation；Krill is one of highest biology of protein content on the earth, and stock number is up to
1000000000 tons, can the amount of adopting up to 100,000,000 tons, be equivalent to the sum of current world's aquatic products total amount.In addition, advantageous extreme environment, makes pole
Ground becomes important genetic resources treasure-house, though the development and application of extreme marine organisms genetic resources are at the early-stage in the world at present,
But the industrial value of multi-million dollar has been brought, therefore, polar expedition is used as by many countries and wins future development initiative, accounts for
Lead the important national strategy of new commanding elevation.Expert points out that south and north poles regions resources are abundant, and geographical location is unique, carries out
Polar expedition is the major issue that the mankind expand survival and development space.
North is gradually reduced along with the range of arctic ice sheet, and the arctic airline is gradually of interest by shipping world；In order to pursue warp
Ji property, major shipping company can select the arctic airline as sea-freight main navigation channel, this will need a large amount of ice formation cargo ship with
Ice breaker, this demand to high performance ship developmental research and market of ship will all generate significant impact；With petroleum resources and
The raising of mining mineral resource technology, the arctic for being known as " second Middle East " are increasingly becoming the base that the mankind ask for resource, this
It is also required to a large amount of polar region offshore equipment and marine worker auxiliary ice breaker, the Ya Maer oil-gas field development project currently carried out is just
It is best clear proof.
For the polar region cargo ship in East Asia-Europe course line and northeast navigation channel of opening the navigation or air flight, ice-breaking course line accounting only accounts for 30%
Left and right, 70% or so course line are spacious water waters.Currently, existing polar region cargo ship is mostly that the ice formation with bulb bow is reinforced
Cargo ship, the ship type open-water performance is excellent, but does not have ice-breaking capacity, and only navigation is navigated in northeast under the conditions of ice breaker pilotage
Road；Either with the ice-breaking type polar region cargo ship of the oblique bow of ice-breaking type, the ship type icebreaking characteristics are excellent, but open-water performance is poor.
