Abstract

Provided is a floating production storage offloading (FPSO) dock mooring rope connection distributing structure. A landing mooring rope point (5) is arranged on the edge, next to water, of a dock (2), a far shore mooring rope point (4) is arranged at the position, behind the water contacting edge and having the same distance as the width of a ship body (1), of the dock (2), a mooring rope is connected between the side board, next to the dock (2), of the ship body (1) and the landing mooring rope point (5), and mooring ropes are connected between the bow part of the side board, close to the dock (2), of the ship body (1) and the far shore mooring rope point (4) and between the stern part of the side board, next to the dock (2), of the ship body (1) and the far shore mooring rope point (4). By utilization of the fact that a plurality of mooring rope points are distributed in a plane mode, the rotating torque and the moving tension of all important parts on FPSO are effectively and evenly decomposed on a bigger loading area of the dock, the anti-drawing ability of the mooring ropes is improved, the total length of the mooring ropes is effectively shortened, engineering investment is reduced, the problem that the FPSO is poor in multi-point mooring performance in a dock area is solved, the FPSO dock mooring rope connection distributing structure can be widely applied to single side multi-point mooring of the FPSO in all kinds of floating type structure forms, operation is safe and stable, the effect is obvious, and the mooring level is remarkably improved.

Description

FPSO pier mooring cable connects distributed architecture

Technical field

The utility model relates to International Classification of Patents B63B boats and ships equipment and technology, and especially FPSO pier mooring cable connects distributed architecture.

Background technology

In the prior art, mooring is to instigate safety such as ship, buoy, platform to stay in the system or the process of anchor or sinker, bank or mooring buoy, generally in the mooring process, need make ship or other buoyancy aids system reside in assigned address with hawser or anchor chain.

FPSO is storage and the transportation of the oil of exploitation being carried out Oil-gas Separation, processing oily sewage, dynamic power, heat supply, crude oil products, the comprehensive large-scale offshore oil production base that integrates the personnel's inhabitation and the chain of command in production.Compare with other form oil production platforms, FPSO have capacity of anti-storm strong, adapt to that depth of water scope is wide, storage/emptying ability is big, and transferable, reusable advantage, extensively be suitable for the exploitation of deep-sea, shallow sea area and marginal oil field, become the main flow mode of production of offshore oil and gas field exploitation away from seashore.

The FPSO mooring system mainly with the FPSO mooring in the operation oil field.FPSO mooring system when the operation of marine site adopts one or more anchor points, one or more standpipe, floating or fixed type floating drum, capstan head or skeleton.FPSO mooring mode has two kinds of permanent mooring and the moorings of releasable formula.Certainly, just begin to play a significant role in FPSO construction phase mooring system.

In the prior art, FPSO mooring technology is constantly brought forth new ideas, as, the mooring of FPSO device of new generation mostly is the radial mooring of rotary type tower multiple spot, and what have also is equipped with a plurality of side thrusters at the bow stern.Spread mooring employing anchor chain and wirerope are combined, and the high anti-corrosion high-strength polyester fiber of employing and the combined mode of anchor chain are also arranged; According to the characteristics that current FPSO hull size increases and operational capability strengthens, newly-built FPSO is also corresponding to be equipped with powerful power system, and design adopts thruster screw propeller technology to improve the viability of large scale hull under vuthan, the quick performance when guaranteeing normally to navigate by water.

In addition, FPSO and other modifications or the newly-built facility waterborne that floats are the same, need the interim mooring of stopping in the depressed place or during harbour, this link outbalance, because the FPSO hull is big and cost is higher, the cable connection technology when it stops mooring also obtains extensive concern.

Chinese patent application CN94101402.9 vessel mooring system, the ocean mooring system comprises: boats and ships, have a hull, a ring-type mooring groove is arranged at its bottom; One floating mooring gear has a top, and it can engage with the mooring groove in the hull bottom; A plurality of cables connect mooring gear in the seabed, and mooring gear remains on the following a certain degree of depth place of hull bottom usually; Be used for promoting the device of this mooring gear to combine with the mooring groove of hull bottom from the previously selected degree of depth, be used for by the water inlet among the mooring groove hastily extracting seawater enter the device of hull, to reduce to act on the downward hydrostatic pressure on mooring gear top when mooring gear and the mooring fillister joint.

Chinese patent application 200980153909.8 is used for the system of the large vessel (10) that mooring is used for production of hydrocarbons, this ship (10) for example is the FPSO ship, described mooring system comprises at least two floating main bodys (17) that hang type, this floating main body is complied with spread anchoring system (12) by means of difference and is moored to sea bed, allows large vessel (10) partly to swing with weather; Riser systems (13,14), it extends to each floating main body (17) from sea bed, and the device that is used for transmitting to large vessel (10) fluid from two floating main bodys (17), floating main body (17) and large vessel (10) are provided with locked plug-in unit (16), sentence the mechanical rigid mode at the bow of ship (10) and stern floating main body (17) is locked onto large vessel (10), thereby the fixing rigidly unit of the integral type that comprises large vessel (10) and floating main body (17) is provided.

Application number: 200610079141.2 1 kinds of offshore float-positioning combined mooring ropes, it is characterized in that: it comprises that an end connects the anchor chain of marine float, the other end connection one of described anchor chain and the fixing anchor fitting in seabed, be arranged at intervals with one group of pouring weight on the described undersea anchor chain, described anchor chain is connected with the sidewall of described anchor fitting, and is embedded in the seabed with anchor chain that described anchor fitting sidewall is connected an end.

The utility model content

The purpose of this utility model is to provide a kind of FPSO pier mooring cable to connect distributed architecture, with the FPSO relative fixed in harbour, and each the significant points rotating torque on the FPSO and mobile tension force effectively is dispersed in big load region on the harbour.

Realize that the measure of the utility model purpose is: the heaving pile point that pulls in to shore is settled at the edge of the nearly water of harbour, settle bank heaving pile point far away in the harbour water receiving edge rear distance identical with beam of hull, hull the go to dock side board and the connection cable between heaving pile point that pulls in to shore, the hull connection cable between bow, stern and the bank heaving pile point far away of side board that goes to dock.

Advantage of the present utility model is, utilization is a plurality of heaving pile points of horizontal distribution, each significant points rotating torque on the FPSO and mobile tension force effectively are dispersed in big load region on the harbour, not only improve the anti-pulling ability of mooring fast, shortened the overall length of mooring fast effectively, reduce construction investment, also solved the difficult problem of FPSO in dock area spread mooring poor performance, can be widely used for the one-sided spread mooring of FPSO of various floating structure forms, the job safety stablizing effect is obvious, significantly improves the mooring level.
