Description

Mooring system
Technical field
The present invention relates to a kind of for by buoyancy aid mooring to the mooring system of another object, this mooring system comprises cable, and cable comprises two rans.
Background technology
Cable is the sea term of hawser or the rope used in mooring or towage.Mooring refers to any mode boats and ships being attached to object (such as bollard, harbour, pier, other buoyancy aid/boats and ships or harborages).A most important factor in marine mooring uses sufficiently long cable to provide enough elasticity, thus allow boats and ships to move due to the motion of wave.If with short and/or hard cable hitch ship while berthing at sea, so, when being in billow, it cannot move and can flood, or it can produce over load in mooring hawser.More elastomeric cable allows up-and-down movement and obvious sideway movement, to avoid being submerged or avoiding to occur over load in mooring hawser.
Summary of the invention
The object of this invention is to provide a kind of mooring system of improvement.This object is realized by the mooring system such as set forth in the following claims.
The invention discloses a kind of mooring system, it comprises cable and the first object and the second object, and wherein, at least described first object is suitable for floating.The first end of the cable of mooring system is attached to described first object, and the second end is attached to described second object, and two objects are hitched by cable thus each other.Cable comprises at least two rans, intermediate friction part is furnished with between these at least two rans, wherein, intermediate friction part extends via fairlead, described fairlead is arranged near the side of described first object, this side is to the second object, and described first end is attached to the attachment point on described first object, and this attachment point is arranged in from described fairlead a distance.The attachment point of the first object is arranged on apart from described fairlead a distance, and this distance at least corresponds to the length of described friction member.
The end of cable means, cable is attached to the first object and the second object there.Actual ran can extend over the attachment point with object.But the part that ran exceedes attachment point extension does not have any technical benefits for object of the present invention.
Ran is suitable for having inner elastomeric relative to described friction member, and thus, the relation between ran elasticity and friction member elasticity is such, makes to think that friction member is hard and ran is elastomeric.
Friction member is suitable for having high friction resistance relative to described ran, thus, relation between the rub resistance of friction member and ran durability is such, makes described friction member can bear friction load without any substantial damage, and this friction load can make described ran wear and tear.
Relation between the length of intermediate friction part and the distance between intermediate friction part and attachment point is such, makes the proper motion of stretch compensation first object allowing ran, and will remain in fairlead by intermediate friction part.
In addition, the distance between fairlead and described attachment point is such, makes ran at least correspond to the length of intermediate friction part in the length at least between intermediate friction part and attachment point.In addition, distance between intermediate friction part and attachment point is such, make the hardness of stretch compensation friction member allowing ran, make the elasticity of the cable of invention at least corresponding to the single rope cable of the length had corresponding to the first ran of the present invention and intermediate friction part.But, the structure with the cable of the invention of intermediate friction part allows the second ran longer, because its can further away from each other the first object the side towards the second object and be attached, thus, compared with cable known before, larger elasticity can be realized, because the total length of ran increases in cable.
Fairlead produces joint, in this joint, when the first object and the second object relative to each other quick travel time, absorb the side force on cable.Thus fairlead makes the ran on every side only can be subject to the power of longitudinal direction, and make first end can be attached at the some place being positioned at the place with a certain distance from the side towards the second object of the first object further.This certain distance means, along the second ran from middle friction member to the distance of attachment point, thus, ran by pilot point on the path leading to attachment point, thus can change the direction of ran.Thus cable can become length to be increased, and in majority of case, compared with the scheme of prior art, this length is close to the twice of the length of the scheme of prior art.Therefore, there is certain elastomeric ran and will provide more elastomeric mooring completely in such a system.In addition, rope is usually than hawser or chain more elasticity, and therefore, cable has extra elasticity by by two rans.

As long as meet above condition, the described attachment point of described first object just at least corresponds to the half of the distance between described fairlead and described second end to the distance of described fairlead, or at least corresponds to the distance between described fairlead and described second end.
In addition, allow intermediate friction part as far as possible effectively to transmit tension force between two rans, the angle that friction member leaves fairlead is very important.Therefore can predict, the attachment point of fairlead and described first object is relative to each other arranged like this, described friction member is made to leave described fairlead with the angle between 0 degree and 90 degree from described fairlead main opening direction, or preferably leave described fairlead with the angle between 0 degree and 45 degree from described fairlead main opening direction, or even more preferably leave described fairlead with the angle between 0 degree and 25 degree from described fairlead main opening direction.
And, second object can be provided with fairlead in the corresponding way, thus, cable is provided with another intermediate friction part, and it is suitable for extending on the second object via described fairlead and the 3rd cable is attached on it to be attached to the 3rd ran of the second object.Thus owing to stretching, rope lengths increases, and the elasticity of cable even can increase more.
According to an aspect of the present invention, the friction member of cable is abrasionproof chain.Except pulling force, the part that cable contacts with fairlead will have friction load, therefore, replace rope to be favourable, thus can increase the service life of cable with chain.Alternatively, the friction member of cable is the abrasionproof hawser that also can increase the service life compared with rope.
According to a further aspect in the invention, rope is made up of nylon or polyester.Nylon and polyester have increase elasticity and than metal filament or chain lighter.
According to another aspect of the invention, fairlead is arranged so that cable runs through the cable conduit of pipeline.Pipeline does not need to safeguard in a large number, such as, can manufacture very light by pulley and cable conduit yet.
According to another aspect of the invention, this system comprises two cables.This allows the balance in roll being controlled object by the main portion of funicular system better.If wish further intensity, so mooring system can be manufactured with two pairs of cables.If desirable strength is very high, so certainly also cable can be increased further.
By increasing longer or more ran, can reach higher elasticity, wherein, the cable of many inventions is arranged in parallel and can increases the intensity of mooring system.In one aspect of the invention, the cable that many are invented is positioned in parallel between the first object and the second object, particularly the cable of pair of parallel layout or two pairs of cables.
According to an additional aspect of the present invention, mooring system comprises mooring rope, and it keeps fairlead and is fixed to object by suspension centre (padeye, pad eye) or other fastening means.Available diverse ways manufactures suspension centre.
According to another additional aspect of the present invention, buoyancy aid is semi-immersed platform.Preferably, fairlead remains on below deck construction by mooring rope, and is at least fixed to and is positioned at semi-immersed platform near the column on the side of another object.
