By arranging cross mooring ropes on the head part of the float-over device, the yaw moment of the float-over device is greatly reduced, and the float-over device can smoothly enter a jacket notch to be smoothly arranged.
Description
Technical field
The present invention relates to the floating holder of a kind of deep water mooring gear, belong to the ocean engineering installing area.
Background technology
Along with the development gradually of China's marine petroleum exploitation technology and Machine Manufacturing Technology, our platform depth of water rapidly increases to more than 300 meter by tens meters.Be accompanied by the increase of the depth of water, the scale that the quantity that reduces platform for cost-cutting increases single platform will be a kind of trend.This macrotype platform has multiple functions such as oil gas processing, generating, personnel's inhabitation.But, when having more multi-functional and advantage, together and the problem of coming to be the weight of large ocean platform sharply increase.At present, the deck chunk weight of deep water sea area platform has reached more than 30000 tons.For the chunk of weight like this, adopt floating holder method to install imperative.At present, only there is the experience of implementing floating holder method at neritic province domain (depth of water is no more than 40 meters) in China, in the floating holder of deepwater regions experience is not installed.
Compare with shallow water area, carry out the floating holder method of deck chunk in deepwater regions and install, its maximum problem be exactly floating holder barge in the positioning moored system of deep water, comprise structure and on-the-spot install etc. of general layout form, the mooring fast of mooring system.
Summary of the invention
The purpose of this invention is to provide the floating holder of a kind of deep water mooring gear.
The floating holder of a kind of deep water provided by the invention mooring gear comprises buoyancy device; Described buoyancy device stem, middle part and afterbody are connected with two groups of mooring fasts respectively at least; The mooring fast of described buoyancy device stem is connected the both sides of described buoyancy device stem across.
In the mooring gear of the present invention, mooring fast and the described buoyancy device of described buoyancy device stem, middle part and afterbody can be flexible connection.
In the mooring gear of the present invention, the free-end of the mooring fast that described buoyancy device stem is intersected is connected on the jacket platform, thereby by the mooring fast that tightens up described intersection buoyancy device is entered in the notch of jacket platform, and then can carry out the installation of platform chunk.
In the mooring gear of the present invention, the mooring fast of described buoyancy device stem, middle part and afterbody is two groups; The quantity of mooring fast can be determined according to the weight of the chunk of delivery in every group of mooring fast.
In the mooring gear of the present invention, the mooring fast of described buoyancy device middle part and afterbody is connected to the both sides of described buoyancy device middle part and afterbody.
In the mooring gear of the present invention, the free-end of the mooring fast of described buoyancy device middle part and afterbody is equipped with anchor, is used for described buoyancy device is fixed in the seabed.
In the mooring gear of the present invention, be equipped with floating drum on the mooring fast of described buoyancy device middle part and afterbody, described floating drum and described mooring fast are flexible connection; Described floating drum can be connected by shackle with described mooring fast; Can determine the connection location of described shackle and described mooring fast according in the middle part of the described buoyancy device and the position of the length of the mooring fast of afterbody and jacket.
The floating holder of deep water provided by the invention mooring gear, by being set at the buoyancy device middle part, mooring fast can resist the buoyancy device skew that certain marine environment power produces, also can reduce simultaneously the motion of buoyancy device, and take full advantage of buoyancy device self windlass of being with and mooring fast, do not use propulsion systems such as screw propeller just can control buoyancy device and advance or retreat; Greatly reduce the buoyancy device yawmoment by the intersection mooring fast is set in stem, thereby guarantee that buoyancy device can enter into the jacket notch smoothly and successfully install.This device is conventional industrial products, and cost is low, can reduce the offshore construction construction investment preferably, and is easy to operate, practical.The depth of water scope that mooring gear of the present invention is suitable for is 50 meters-500 meters.

The specific embodiment
The invention will be further described below in conjunction with specific embodiment, but the present invention is not limited to following examples.
Embodiment 1, deep water barge mooring gear
The structure of mooring gear of the present invention as depicted in figs. 1 and 2, each mark is as follows among the figure: 1 barge, 2 deck chunks, 3 afterbody mooring fasts, 4 middle part mooring fasts, 5 stems intersect mooring fast, 6 jackets, 7 jacket legs, 8 shackles, 9 floating drums.
Mooring gear of the present invention comprises barge 1, carrying deck chunk 2 on the barge 1; The position of symmetry respectively is connected with one group of afterbody mooring fast 3 on the side of a ship of the both sides of barge 1 afterbody, and every group of afterbody mooring fast 3 comprises 3 mooring fasts, and the free-end of every group of afterbody mooring fast 3 all connects anchor, is used for fixedly barge 1; The position of symmetry respectively is connected with one group of middle part mooring fast 4 on the side of a ship of the both sides, middle part of barge 1, and every group of middle part mooring fast 4 comprises 3 mooring fasts, and the free-end of every group of middle part mooring fast 4 all connects anchor; All be connected a floating drum 9 by shackle 8 on every group of afterbody mooring fast 3 and the middle part mooring fast 4, this floating drum 9 is used for the position of sign mooring fast; Respectively be connected with one group of stem on two sides of a ship of the stem of this barge 1 and intersect mooring fast 5, these two groups of stems are intersected mooring fasts 5 and are connected across on two sides of a ship of stem of described barge 1, and this stem is intersected the other end of mooring fast 5 and is connected on the jacket pin 7.
The using method of mooring gear of the present invention is as follows:
1) when the barge 1 of delivery deck chunk 2 travelled on the marine site, 250m place in jacket platform place in place, the position according to floating drum 9 signs connected afterbody mooring fast 3 and middle part mooring fast 4 one by one.Then, recycling back work ship connects the stem intersection mooring fast 5 of barge 1;
2) when environmental conditions reaches requiring of floating holder installation, by twisting stem intersection mooring fast 5 and the middle part mooring fast 4 of tight barge 1, make barge 1 enter into jacket 6 notches.If environmental forces is bigger, the bow of barge 1 is difficult to enter jacket 6 notches, can be by regulating the pulling force of handing over stem fork mooring fast 5, and degree ground changes the direction of barge 1 bow a little; When in a big way mobile barge 1 of needs, can control realization by middle part mooring fast 4 and the afterbody mooring fast 3 of barge 1.Thereby barge 1 is fixed in the installation of finishing deck chunk 2 in jacket 6 notches.
In the mooring gear of the present invention, the quantity of mooring fast group can be regulated according to the weight of delivery deck chunk; The material of mooring fast (wirerope or nylon cable etc.), length, diameter and radical can be regulated according to the weight of the depth of water and delivery deck chunk; When using mooring gear of the present invention, can be with the buoyancy device mooring in distance jacket one side 200-300m place.The operating range of mooring gear of the present invention is apart from the beginning of jacket one side 200-300m place, to the jacket notch of platform.
