Description
Technical field
The present invention relates to the three bow thruster ship body characterized by low resistance adopting super U-shaped waterline, belong to field of ocean engineering.
Background technology
Along with the lasting aggravation of global greenhouse effect, green, low energy consumption ship, particularly the development and Design of ocean engineering class boats and ships more and more causes the concern of industry.Ocean engineering class boats and ships, such as wind turbine installation vessel etc., due to the engineering characteristic of itself, need to have suitable deck payload space and failure-free stationkeeping ability.Therefore, it is longer that this type of ship is generally square body, the shallow draft full formed ship oceangoing ship that the section of becoming a mandarin, after run are all very short.When larger block coefficient and the too short section of becoming a mandarin cause this type of ship's navigation, resistance is higher, and quick performance is poor; And more general fine ship oceangoing ship is compared, need larger dynamic positioning ability.
Summary of the invention
In order to realize above-mentioned object, the invention provides a kind of three bow thruster ship body characterized by low resistance adopting super U-shaped waterline.
The technical scheme that the present invention takes is as follows:
Three bow thruster ship body characterized by low resistance of super U-shaped waterline, comprise hull; Hull comprises stem, middle part and afterbody; Stem has the very thin and dished flat line of a head end; The stem with the first post of straight bow is connected to form by flat line and super U-shaped waterline, the transition of main deck line fairing of curves; The bottom of stem has several bow thruster installation pipe tunnel; Middle part is square body, adopts at the bottom of circular arc turn of the bilge connected boat; Afterbody is square tail form, comprises rising hull bottom; Stem, middle part, afterbody carry out smooth connection and form hull lines.
The quantity of bow thruster is three.
Stem is straight bow, and stem comprises two super U-shaped drinking water waterplanes: ballast draft waterplane, scantling draft waterplane and a head end are very thin is the flat line face of spill, main deck line face; Flat line face transits to described ballast draft waterline place and scantling draft waterline place by fairing of curves; Scantling draft waterplane is by inclination flare and described main deck contours connection.
It is 0.62 ~ 0.7 that super U-shaped waterline refers to coefficient of waterplane; Half angle of entrance is 80 ° ~ 90 °.
The very thin flat line face in spill of head end, flex point is consistent or slightly forward with the 3rd bow thruster home position in position, captain direction, should ensure that the 3rd bow thruster pipe tunnel width is not more than thruster diameter 2.5 times.
Middle part is a square body part.
Square body partial-length accounts for superintendent officer's 60% ~ 70%.
Afterbody is a square tail.
The hull bottom wicking height of square tail is 0.2 ~ 0.25 with length ratio.
Beneficial effect of the present invention: adopt coefficient of waterplane to be 0.62 ~ 0.7; Half angle of entrance is the super U-shaped waterline of 80 ° ~ 90 °, with the square body part accounting for hull overall length more than 60%, actv. meets middle low speed ocean engineering class boats and ships to while deck payload space and volume of compartment requirement, the wave making resistance be subject to when greatly reducing ship's navigation, improve the rapidity of boats and ships, economy and practicality.Stem can arrange installation three pipe tunnel formula side thrusters, and maximum thrust loss is no more than 10%, coordinates with the propelling unit of afterbody, can be economical, reliably realizes remarkable dynamic positioning function, improves reliability and the flexibility ratio of Engineering shipping work.Ballast waterline and design load water line stem all adopt super U-shaped waterline design, can take into account the economy of boats and ships under various running working condition.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
As Figure 1-3: three bow thruster ship body characterized by low resistance of super U-shaped waterline, comprise hull 1, hull 1 comprises stem 2, middle part 3 and afterbody 4.Stem 2 has the very thin and dished flat line 5 of a head end.The first post 8 of straight bow is connected to form by flat line 5 and super U-shaped waterline 6, main deck line 7 fairing of curves transition.Stem also has bow thruster installation pipe tunnel 9, is preferably 3 bow thruster forms, to overcome the thrust loss impact that the beam causes.Middle part 3 is square body, is preferably and adopts at the bottom of circular arc turn of the bilge connected boat.Afterbody 4 comprises and raises hull bottom 10, after run flow field during to improve navigation.By stem 2, middle part 3, afterbody 4 carries out smooth connection and forms hull 1 molded line.
Stem 2 is straight bow, and stem 2 comprises two super U-shaped drinking water waterplanes: ballast draft waterplane, scantling draft waterplane and a head end are very thin is the flat line face of spill, main deck line face; Flat line face transits to described ballast draft waterline place and scantling draft waterline place by fairing of curves; Scantling draft waterplane is by inclination flare and described main deck contours connection.
It is 0.62 ~ 0.7 that super U-shaped waterline refers to coefficient of waterplane; Half angle of entrance is 80 ° ~ 90 °.
The very thin flat line face in spill of head end, flex point is consistent or slightly forward with the 3rd bow thruster home position in position, captain direction, should ensure that the 3rd bow thruster pipe tunnel width is not more than thruster diameter 2.5 times.
