Description
Technical field
The present invention relates to deepwater work platform repair ship technical field, relate in particular to the multipurpose ocean platform repair ship of the development activities that is used for Unlimited Navigation Areas marine oil gas resource.
Background technology
Since 21st century, along with deepen the development activities of marine oil gas resource day by day countries in the world, to the increasing demand increase of this type of platform repair ship high performance ship.Through careful market study and analysis; The AHTS boats and ships that international ocean engineering ship market surpasses power 10000HP and the PSV boats and ships of deadweight cargo tonnage above 2000 tons are as the standard that can adapt to deepwater work; Whole world shipowner upgrades and builds boats and ships and also concentrates on high-power AHTS boats and ships and the above PSV boats and ships of 2000 deadweight cargo tonnagies more than 10000 horsepowers, and market outlook are wide.
Wherein power surpasses 10000HP platform towing/anchor handling/supply vessel AHTS for grasping anchor/traction/supply service ships; Be mainly used in Unlimited Navigation Areas towage operation; Can carry out ship; Refute, the towage work of drilling platform etc., externally fuel feeding, drilling well water, potable water, dry bulk cargo, mud, salt solution and deck cargo, and have external fire-fighting function.European's design-calculated platform repair ship is universally acknowledged specific ship type, and well-known design corporation of external several families accumulates through design for many years, has formed the practicality combination of this kind ship type principal dimensions and ship form coefficient.
Through the induction-arrangement to tens of surplus type platform repair ships, it is perfect inadequately, reasonably local inadequately that the platform repair ship of building at present also exists, and mainly contains following several respects:
(1) the general horsepower of current platform repair ship is bigger, and hull demension is smaller comparatively speaking, causes diameter of propeller to be restricted, and spacious water efficient and hull efficiency are lower, and overall propulsive efficiency is not high.
(2) the current platform repair ship generally adopts Shears to do the tailing axle support, adopts single-point to support or the two point support according to the size of horsepower and the length of tailing axle, and build process is complicacy quite, and Shears has caused very big appendage drag to boats and ships.
(3) the midship front portion generally is located in this ship type cabin, is positioned at below the superstructure, adds the vibration between tail undercarriage and the hull, makes the vibration of boats and ships and noise be difficult to control.
Summary of the invention
Technical matters to be solved by this invention provides a kind of raising hull efficiency and overall propulsive efficiency, reduces hull appendages resistance, the vibration of boats and ships and the deepwater work platform repair ship of noise.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of deepwater work platform repair ship is characterized by: single hull, the two oars of two sterns; The ship stern adopts inward turning fin stern, and ship bow part is bulbous bow and suitably leans forward that engine room arrangement is anterior at the ship midship; All accommodations are arranged in the stem superstructure, and main cargo deck is accessible layout.
Described deepwater work platform repair ship is installed two groups of counter rotating propellers as main thruster on the diad of ship stern, every group of counter rotating propeller is made up of adjustable pitch propeller and a full circle swinging screw propeller of a carrying pipe.Can optimize wake, solve the vibration resistance problem, and increase propeller thrust.
Described deepwater work platform repair ship is installed two thrusters at ship bow part.
Said pair of inward turning fin tail is two long tunnel inward turning fin tails.
The conduit of the adjustable pitch propeller of said carrying pipe combines with the hull fairing.
The adjustable pitch propeller of said carrying pipe is the major diameter adjustable pitch propeller of carrying pipe.
Each item technical index of the present invention is compared with boats and ships of the same type and is greatly improved:
(1) the ship stern is an inward turning fin tail type, has saved shaft bossing, and Shears reduces appendage drag, and is total energy-conservation more than 10%.
(2) stern wake of inward turning fin tail ship type is very even, and vibration and noise reduce than common ship type greatly, reduces the expense expenditure that reduces noise and vibration, saves cost.
(3) cooperate the ship type, optimize the promotion program design.Adopt bavin electricity hybrid propulsion; If 4 overlap independently propulsion system; Each is made up of the right and left the major diameter adjustable pitch propeller (CPP) and a cover full circle swinging screw propeller of a diesel-engine generator, a carrying pipe, and CPP and full circle swinging propeller shape transfer from one department to another system (CRP) in pairs.This promotion program has not only increased the manipulation redundancy under the situation that does not increase power configuration, make maneuverability pattern more flexible, also can further increase the speed of a ship or plane and bitt towing tension.
(4) CRP propelling unit of the present invention adopts to be equipped with a pair of counter rotating propeller, and bow oar is opposite with back oar hand of rotation; The flow field is the preceding flow field of oar of back oar behind the oar of bow oar; As after this preceding flow field of oar is opposite with its rotation direction, produces the effect of prewhirling, thereby improves the propulsion coefficient of oar greatly; Originally be assigned to the power on the screw propeller and be assigned to now on two screw propellers, this also can increase the propulsion coefficient of oar greatly.
(5) two of afterbody full-rotating rudder paddles not only can participate in promoting mainly into, and the thrust of side direction can also be provided.In the time of normal the navigation, 4 oars are worked simultaneously, and two cover full circle swinging screw propellers replace rudder gears to guarantee course stabilities; Then rely on two cover full circle swinging screw propellers and two first thrusters of bow, two stern thruster collaborative works of afterbody when leaning on slipping from alongside or dynamic positioning.This promotion program has not only increased the manipulation redundancy under the situation that does not increase power configuration, make maneuverability pattern more flexible, also can further increase the speed of a ship or plane and bitt towing tension.
Comprehensive above prioritization scheme can obtain to reduce the income of resistance 10%, and has obtained the effect of vibration and noise reducing.
