To refer to that crane 114 is located on the top side 111a of the first hull 111.This arrangement is better than crane traditional arrangement aboard ship,
Reason is that ground jack is conventionally positioned at bow or the quarter office of known ship, wherein existing in the position that crane is located at weak
There is weak balancing gravity to resist by any load of crane lifting in buoyancy and/or the opposite segments being located in crane.This
Sample, it is known that ship need in operation complexity ballasting conciliate ballasting so as to lift load.Such complicated pressure
Cabin is conciliate ballasting and generally requires accurate coordination, and otherwise ship may tilt or tiltedly stick up in operation, this can to ship and
Its personnel component is dangerous.However, in the utility model, crane 114 is arranged in and is in a ratio of larger hull with the second hull 112
The top of the first hull 111, to cause that acting on the very big buoyancy on the first hull 111 by water body in operation carries
Supplied stabilization and power essentially upward, these power offset by the part of ship 110 weight and by crane 114 lifted it is any
Any downward power that load is produced.
The significant portion of crane 114 is preferably arranged substantially in the center section of the first top side 111a of the first hull 111
About and over.Each crane 114 is A-derrick, including the first mast 114a and the second mast 114b, the first mast
Around pivot 114d, pivotably and at another end by cable 114c, (it is wrapped at an end for bar 114a and the second mast 114b
Include but be not limited to rope and chain) connection.Crane 114 is preferably A-derrick, because such crane is compared to identical
The rotary crane of ability is more economical.In addition, more cranes are added for rotary crane (carrying out below
Illustrate) ability be it is impossible, reason be the design phase space be designated it is special rotated for the possible gib arm of crane, it is not
Can be modified in the later stage.It is to be appreciated, however, that depending on application and requiring, crane 114 is alternatively rotary lifting
Machine.First mast 114a extends the side of simultaneously thwartships 110 at the first hull 111.Cable 114c is via suitable pulley
System (not shown) connects the first mast 114a and the second mast 114b.One end of cable 114c is connected to capstan winch 114e or can
Cable 114c is reeled and/or winds to lift any suitable equipment of load via the other end of cable 114c.Can automatically or
The manually operated capstan winch 114e of person.As illustrated in fig. 4, the significant portion of crane 114, i.e. the first mast 114a, the second mast
Bar 114b and pivot 114d, is arranged substantially in around and above the center section of the first top side 111a of the first hull 111, and twists
Disk 114e is positioned on the platform 113 between the first hull 111 and the second hull 112.In this arrangement, crane 114
Most of weight is acted on the first hull, downward towards water body.The weight of crane 114 is applied in first contacted with water body
Upward buoyancy on hull 111 is offset.This arrangement improves and increased the hoisting power of ship 110, and reason is in operation
During, very big upward buoyancy on the first hull 111, buoyancy confrontation by the part on platform 113 and by
Any opposite and downward power that the weight of any load of the lifting of crane 14 applies.Second hull 112 is in operating process
In serve as balance weight, to aid in upward buoyancy on the first hull 111.The second hull 112 is allowed to serve as balance weight
Power includes the weight of the second hull 112 and any ballast in its ballasting separation.The first big hull 111 also improves ship
110 stability, because larger surface area increased displacement and transfer increased to act on first hull 111
Buoyancy.
Ship 110 preferably includes to be arranged substantially in around and above the center section of the first top side 111a of the first hull 111
At least two cranes 114, as illustrated in figures 5 a and 5b.Lifting operation mistake of two or more cranes 114 in ship 110
Advantageously disperse the weight of elevated load in journey and the pressure and power that make to act on the first hull 111 are uniform.Lifting
Machine 114 is positioned and removable along track (rail bar) 119, and track 119 is located on the first hull 111 or first on platform 113
The top of hull 111, as illustration is given in figure 6 a andb.Preferably, pivot 114d engagement rails 119 and can be moved along track 119.
Pivot 114d also will move the first mast 114a, the second mast 114b and cable 114c along the movement of track 119.Crane
114 preferably lock in place during the lifting operation of ship 110.Track 119 is preferably along the first hull 111 or platform 113
Edge positioning, in nearby water bodies, to cause that crane 114 can be extended substantially out and crossed during lifting operation
The side of ship 110, so that the infringement to ship 110 is minimized.Track is arranged and prolonged substantially along the center section of the first hull 111
Stretch and with the length of the longitudinal axis for being arranged essentially parallel to the first hull 111.Preferably, the end of track 119 does not extend
To the bow and stern section of the first hull 111, reason is that crane 114 can not possibly be positioned at that ground in operational state
Side, because there is the lifting that weak buoyancy carrys out auxiliary loads at such position.However, as shown in Figure 6b when presence is more than
In the case of two cranes 114, crane 114 may be positioned to the bow and/or stern section close to the first hull 111.Rise
The quantity of heavy-duty machine 114 and its along track 119 position will depending on application and loading demands.The hoisting power of ship 110 will be with
The quantity of crane 114 and increase.Capstan winch 114e can also be positioned, be bonded on track (not shown) and can prolong track movement, rail
Road is located on the platform 113 between the first and second hulls 111,112.This allow capstan winch 114e relative to the first mast 114a,
The movement of the second mast 114b, cable 114c and pivot 114d and move.
Data process system includes at least two position thrusters 115.Preferably, data process system includes multiple position thrusters 115.
The requirement that the quantity of position thrusters 115 will depend on the application of ship 110 and be related to.Can for example manually, via user operate
Computer system remotely or can and computer system is automatically via sensor (being arranged on the correct position on ship 110)
Control position thrusters 115.It is preferred that operating and driving by the engine different from main thruster 116 and azimuth thruster 117
Position thrusters 115.When ship 110 is in operation, the function of position thrusters 115 is dispatching ship 110 and be located at
Its destination locations.Position thrusters 115 are arranged in the lower section of platform 113 and its position can be attached in the upper part of cylinder 118
It is near such as in the case of without cylinder around the periphery of the first hull 111.Position thrusters 115 can also be via suitable
Attachment arrangement be attached to the bottom side of platform 113.In the transit condition of ship 110, the position of position thrusters 115 is outside water body
Face, and in the mode of operation of ship 110, position thrusters 115 are immersed in water body.Depending on application and requirement, positioning propulsion
Device 115 is also disposed at around the cylinder 118 of the second hull 112 or around the periphery of the second hull 112.In prior art
Ship in, position thrusters are usually located at the bottom of hull.Therefore the ship of prior art can not be lifted in shallow water
Operation, reason is the draft of the position increase ship of these position thrusters.Therefore, the position thrusters in the utility model
115 arrangement permission ship 110 carries out lifting operation in the shallow water limited with draft, because position thrusters 115
Around the periphery of ship 110.Additionally, position thrusters 115 need not shrink when ship 110 is into shallow water or in dry dock
Or remove.The position of position thrusters 115 has some advantages outside water body in transit condition, and this is included but is not limited to：
Reduce abrasion --- because position thrusters 115 are dry in transit condition and are not used by being pushed away so as to extend positioning
Enter the life-span of device 115, improve the easy of maintenance, repair and replace when ship 110 is in offshore to position thrusters 115
Property --- because position thrusters 115 easily accessible in transit condition, reduce the navigation friction of ship 110 --- because positioning
Propeller 115 does not bring towing, and improves the easiness to the dry dock inspection/repairing of ship 110.In operational state,
Ship 110 is ballasted in water body via the first and second hulls 111,112, so that position thrusters are submerged.Depending on application,
Position thrusters 115 are extensible and may be collapsible into water-outlet body.
In operation
Fig. 7 a provide plan and body plan of the ship 110 in its transit condition and Fig. 7 b exist there is provided ship 110
Plan and body plan in its mode of operation.With reference to Fig. 7 a, when ship 110 is in transit condition, the first and second hulls
111st, 112 low portion is swum on the surface of water body 120.In a state, the position of the bottom side of platform 113 be higher than and
Away from the surface certain distance of water body 120, higher than horizontal plane 121.Position thrusters 115 are also positioned above and away from water body
120 surface certain distance, higher than horizontal plane 121.When in the transit condition, position thrusters 115 are dry and easy
In close to placing under repair, safeguard and replace.When ship 110 is advanced, position thrusters 115 are also subject to less abrasion, and not
Bring towing.In transit condition, the second hull 112 serves as outboard floating body and provides stability with to ship, particularly in traveling
During.Due to the surface area very little that the second hull 112 is contacted with water body, so ship 110 can be traveling at high speeds.
When ship 110 has reached purpose offshore position to perform lifting operation, the first hull 111, the second hull 112 and/
Or the ballasting separation (not shown) of platform 113 will be filled suitable ballast, ballast includes but is not limited to water and cement.
During the filling of ballasting separation will make ship 110 force down water body 120, so that the first hull 111 and the second hull 112 are immersed into water body
In 120, under horizontal plane 121.The ballasting of ship 110 will also cause that position thrusters 115 and cylinder 118 are immersed into water body
In 120, under horizontal plane 121.Finally, when platform 113 contacts water body 120 or the completion when platform 113 is close to horizontal plane 121
Conversion of the ship 110 from transit condition to mode of operation.Preferably, platform 113 is placed in during lifting operation and floats on water
On body 120, as shown in figure 7b.It is favourable that platform 113 is swum on the surface of water body 120, because platform 113 is provided greatly
Floating surface product and given to ship 110 in operational state improvement stability buoyancy.
In operational state, position thrusters 115 operate paired ship 110 to perform and are accurately positioned, and this includes ship 110 is accurate
Move to purpose offshore position, ship 110 for example is positioned at into the side of load 130, and (wherein the first hull 111 is adjacent to load
130), and/or by the position stabilization of ship 110 in purpose offshore position.Can there is load or in the absence of load in position thrusters 115
Function when lotus.Position thrusters 115 are independently operable or operated as one group of propeller.If desired, can activate
Main thruster 116 and azimuth thruster 117 aid in being accurately positioned to ship 110.
In showing lifting operation in the body plan of Fig. 7 b, one end of cable 114c is attached to load 130.By twisting
Disk 114e enhances load 130 by reeling for cable 114c via the cable other end from water body 120.First mast
114a and the second mast 114b can be also pivoted come the lifting of auxiliary loads 130 by around pivot 114d.As an alternative or volume
Buoyancy of the increasing action on the first hull 111 is carried out in other places, the cabin that can be extracted of the ballasting separation in the first hull 111, to cause
First hull 111 will be enhanced and higher than water body 120 with by load 130 to floating from water body 120.In addition, the second hull
112 can further be ballasted and are lifted out load 130 and higher than water body 120 with serving as balance weight.It is to be understood, therefore, that lifting
The ballasting of the hull of the operation of machine 114, first and/or second 111,112/solution ballasting or its combination will cause that load 130 is lifted out
And higher than water body 120.It will be understood that, because platform 113 is swum on water body 120 in operational state, so the first and second ships
Body 111,112 need not be ballasted/solve ballasting, and reason is that the big surface area of platform provides sufficient stability to ship 110
And buoyancy --- even when lifting load 130, you can just lift load by simply reeling cable 114c
130.This is favourable, because ship 110 need not be coordinated and synchronous first and/or second hull equipped with complicated equipment
111st, 112 ballasting conciliates ballasting.When 130 elevated water-outlet body 120 of load, position thrusters 115 are operable to make ship 110
Move and make load 130 to be left from lifting place and on another ship.Falling for load 130 discharges including operation crane 114
Cable 114c, the first hull of ballasting 111, solution ballasting second ship body 112 or its combination.
Load 130 can be any weight, and reason is：If the weight of load 130 exceedes the hoisting power of ship 110,
Load 130 can be lifted using more than one ship 110, as provided in Fig. 8.Preferably, a ship 110 can lift weight
Measure the load 130 more than 100 tons and more preferably up to 10000 tons.Depending on application, a ship 110 being capable of lifting weight
Load 130 more than 10000 tons.Therefore, when there is two ships 110 as shown in Figure 8, total hoisting power of lifting operation can
It is double, for example, load 130 can 20000 tons or heavier of weight.When there is more than one ship 110 and be involved in lifting operation, ship
110 can be equipped with suitable equipment, including but not limited to for the equipment that is exchanged between ship 110 and for ensuring ship
The sensor on ship 110 of the safe distance between 110 and/or load 130.
When the lifting operation is completed, will to the first hull 111, the second hull 112 and/or platform 113 carry out solution ballasting with
Increase the buoyancy of ship 110.During ship 110 is changed from mode of operation to transit condition, platform 113 is moved away from water body 120
Move and higher than water body 120 with positioned at a certain distance from horizontal plane 121.The distance will depend on perform solution ballasting amount or
The amount of the ballast left in ballasting separation.Position thrusters 115 will also remove water body 120.When in transit condition, positioning
Propeller 115 is in the outside of water body 120 and platform 113 does not preferably contact water body, under only the first and second hulls 111,112
Portion part contacts with water body 120.Then the next position can be operated, navigated and driven it to ship 110.
