Abstract

The utility model provides a leg type single point mooring device of deep water tension, which is composed of an anchoring system, a mooring system and an oil-transportation pipeline system. The leg type single point mooring device of deep water tension is characterized in that the anchoring system is formed by that a plurality of tension anchor chains or cable legs (2) make an anchoring buoy (3) connect with a sea-bottom anchor body, and the anchoring buoy (3) is arranged underwater in certain depth. Compared with the existing catenary leg-type single point mooring device (CALM), the leg type single point mooring device of deep water tension is called a (TALM) device; the leg type single point mooring device of deep water tension has the main advantages that the length and the weight of the anchor chain or the cable leg (2) are shortened, the fabrication cost of the leg type single point mooring device of deep water tension is lowered correspondingly, and the drawing of the layout of the leg type single point mooring device of deep water tension can be seen from an attached drawing.

Description

A kind of deep water tension leg type single point mooring unit
Technical field
The utility model belongs to a kind of new in the marine oil tanker single point mooring unit.
Background technology
Present marine oil tanker single point mooring unit has many types such as single anchor leg, many anchors leg, wherein sees so that catenary anchor leg mooring (CALM) comparatively more in many anchors leg type.The anchoring system of this kind single point mooring unit is the anchoring buoy of the water surface is connected in seabed anchor body and is constituted by some stretched wire anchor legs, and the mooring fast of ship promptly links to each other with anchoring buoy.The mooring capacity of anchoring buoy depends on the catenary parameter of stretched wire anchor leg.(chain line length overall and single long weight) and arrange under the bigger condition of the depth of water, is the requirement of the satisfying mooring force big and heavy amount stretched wire anchor cable of many appreciable lengths of needs often, thereby makes the cost of this type of mooring gear generally higher.
Summary of the invention
In order to overcome the problems referred to above in the catenary anchor leg mooring in the deep water (CALM), the utility model adopts tension force anchor leg to replace stretched wire anchor leg, simultaneously anchoring buoy is moved in the suitable degree of depth under water from the water surface, thereby the length of anchor leg, weight are greatly reduced, the corresponding reduction of its cost.
The technical scheme in the invention for solving the technical problem is: a kind of deep water tension leg type single point mooring unit (TALM), form by anchoring system, mooring system and delivery line system, it is characterized in that said anchoring system is the anchoring buoy below the water surface is linked to each other with seabed anchor body and to be constituted by tension force anchor chain or cable leg.Seabed anchor body wherein is a suction anchor, and there is the hanger that connects anchor chain or cable leg each center mast both sides, anchor top; Anchoring buoy wherein places certain depth under water, has some overhanging beams corresponding with anchor top hanger around it, and in order to connect anchor chain or cable leg, the center of top of anchoring buoy is equipped with mooring rotating disk and oil transportation rotating disk.The mooring swivel mount also is housed on the mooring rotating disk, the oil transportation swivel joint is arranged on the oil transportation rotating disk.Mooring system among the TALM is made up of the mooring swivel mount more than the anchoring buoy top, ballast box, friction chain, mooring buoy, mooring fast and bolt chain floating drum, and bolt chain floating drum outer end links to each other with mooring object oil tanker with mooring cable.Delivery line system among the TALM is made up of three parts from bottom to top, promptly by the seabed manifold through the compliant riser of middle floating drum to the anchoring buoy bottom fitting, draw the oil transportation steel pipe that places on the mooring swivel mount by the oil transportation swivel joint on anchoring buoy top, and the flotation hose of connection oil tanker etc.
Because the single point mooring unit of the utility model (TALM) is the stretched wire anchor leg that replaces (CALM) type with tension force anchor chain or cable leg, and its anchoring buoy is placed below certain depth of water, thereby reduce length of chain cable and weight greatly, so can corresponding reduction anchoring system and the cost of whole device.Be described further below in conjunction with drawings and Examples.

The specific embodiment
At this tension leg type single point mooring unit with the 100m depth of water is example.With regard to its corresponding structure system, yardstick, layout and marine mounting means thereof, be described further in conjunction with the accompanying drawings.The anchoring system of this device is by 3 suction anchors (1), article 6, anchor chain or cable leg (2) and one place anchoring buoy (3) composition of the following about 20m of the water surface, their principal dimensions respectively by the anchor top loading of the desired tension leg initial tension of mooring oil tanker, the corresponding buoyancy of anchoring buoy (3) and suction anchor (1) carry determine.Wherein the diameter of suction anchor (1) is 5m, highly is about 10m, and anchor top width between centers is about 20m; The height of anchoring buoy (3) is about 5m, and diameter is about 15m, the overhanging beam (18) that to have 3 length be 5m; Article 6, the every 80m of length of tension force anchor chain or cable leg (2).The yardstick of each component part also carries performance only by the required system of mooring oil tanker and decides in the mooring system of this device.The component part of the delivery line system of this device is decided by design oil transportation ability.Suction anchor in the whole set (1), anchoring buoy (3), other floating drums and mooring swivel mount steel structures such as (6) can be made voluntarily, and other all can be purchased in market as chain, cable and various pipeline.This covering device is finished the split manufacturing in the place, bank and is assembled by system, just can borrow crane barge and barge to implement marine delivery and installation subsequently.Its marine erection procedure is as follows:
1. crane barge at sea objective cast anchor in place;
2. related 6 anchor chains of 3 suction anchors (1) in the anchoring system or cable leg (2) and anchoring buoy (3) are hung entry successively together with its top arrangement mooring rotating disk (4) and oil transportation rotating disk (5), accurately in place and make its bottom insert the seabed until suction anchor (1), with anchoring buoy (3) water filling, make its buoyancy, gravity in a basic balance in this process;
3. to suction anchor (1) according to a conventional method (as the exhaust method of drowning oneself) implement the suction injection, until all sinking to the seabed;
4. anchoring buoy (3) is implemented inflatable drainage, make inflation pressure near external water pressure, make filled volume reach required buoyancy, thereby make anchor chain or cable leg (2) obtain predetermined initial tension, so far anchoring system installs;
5. subsequently by accompanying drawing 1 the mooring rotating disk that is shown in (4) mooring swivel mount (6), ballast box (7) go up to be installed, to be connected friction chain (8), mooring buoy (9), mooring fast (10) and bolt chain floating drum (11), finish the mooring system installation;
6. the delivery line system is installed at last, promptly compliant riser (12) is received the standpipe joint (15) of anchoring buoy bottom through middle floating drum (14) from seabed manifold (13), again oil transportation steel pipe (16) is installed on the swivel mount (6), at last that flotation hose (17) is coupled.
So far, the sea of the utility model (TALM) device is installed and is all over, and can drop into offshore oil wheel mooring and oil transportation operation.
