Abstract
Novel support pipe frame motion compensation equipment is a set of hydraulic system which is composed of a hydraulic cylinder, an upper portion energy storage machine, a lower portion energy storage machine, an air bottle and the like. The novel support pipe frame motion compensation equipment is characterized in that a connection rod is arranged on the top of a stern truss structure, a pulley group is fixedly arranged on the end portion of the connection rod and used for guiding a mooring rope which is connected with a winch and a support pipe frame, a hydraulic cylinder of a motion compensation system is vertically arranged as soon as possibly, two ends of the hydraulic cylinder are respectively hinged with the connection rod and the stern truss structure, and part pressure of the hydraulic cylinder is adjusted according to radius and working conditions of different spreading pipes. When the support pipe frame moves downwards, force on the mooring rope is increased to drive the connection rod to downwards move, gas in the hydraulic cylinder is compressed, the pressure is increased, the connection rod is ejected upwards, and therefore, the mooring cable drives the support pipe frame to move upwards, and vice versa. The novel support pipe frame motion compensation equipment is wide in application range, and suitable for the radius of different spreading pipes and the working conditions of spreading pipe working, pipe abandoning, self storing, sailing and the like, and obviously improves stress effect of the mooring rope. When the mooring rope is selected, specification can be reduced in an appropriate mode, and cost is reduced.
Description
Technical field
The present invention relates to the equipment of a kind of Novel supporting pipe support Motion Compensation.
Background technique
The pipe support rack pipe laying is the common method that present in the world offshore oilfield pipeline is laid, this method easy construction, and investment economizes most, and the duration is the shortest.And the pipe support rack pipe laying barge can meet with various sea situations when actual pipe laying, and at this moment pipe laying barge needs pipe abandon, certainly deposits or navigation etc.Thereupon and up and down heave of pipe support rack in this process, therefore the hawser that connects winch on pipe support rack and the ship is also bearing the power of uncertain instantaneous variation, or tensioning, or loosens, and affects hawser working life.
Summary of the invention
In order to reduce above-mentioned impact, the invention provides the equipment of a kind of Novel supporting pipe support Motion Compensation, it can compensate up and down heave movement of pipe support rack effectively, thereby reduces the impact on pipe installation; Alleviate simultaneously the variation of the power on the hawser that connects pipe support rack, so that hawser unanimously is in the comparatively mild tensioning state of variation.And then when selecting hawser, can suitably reduce specification, reduce expenses.
1. the equipment scheme of a kind of Novel supporting pipe support provided by the invention Motion Compensation is as follows:
(1) truss structure top installing connecting rods on the quarter, interlinking lever end is installed the fixed pulley group, in order to the hawser of lead connection winch and pipe support rack.
(2) oil hydraulic cylinder of motion compensating system is vertically laid as far as possible, and two ends link with connecting rod and stern truss structure respectively.
(3) according to different pipe laying radiuses, and pipelaying work, pipe abandon, certainly deposit and the operating mode such as transportation, by adjusting gas cylinder number, top energy storage canister and bottom energy storage canister pressure etc., adjust the zero-bit pressure of oil hydraulic cylinder.
(4) when pipe support rack moves downward, power on the hawser increases, and drivening rod moves downward, and oil hydraulic cylinder gas is compressed, and pressure increases, with connecting rod top upwards, and then so that hawser drives pipe support rack moves upward; When pipe support rack moved upward, the power on the hawser diminished, and piston rod moves upward, and it is large that the oil hydraulic cylinder gas volume becomes, and pressure reduces, with connecting rod upwards the power on top reduce, and then so that hawser drives pipe support rack moves downward.And so forth, play the motion of compensation pipe support rack, alleviate simultaneously the effect of the variation of the power on the hawser that connects pipe support rack.
2. the equipment of a kind of Novel supporting pipe support provided by the invention Motion Compensation is as follows:
The equipment of a kind of Novel supporting pipe support Motion Compensation is to be positioned under the connecting rod by a cover, the hydraulic system that connects the compositions such as oil hydraulic cylinder of connecting rod and stern truss, what link to each other with oil hydraulic cylinder is top accumulator, bottom accumulator and the gas cylinder etc. of regulating gas in the jar pressure.
(1) oil hydraulic cylinder: oil hydraulic cylinder quantity should be according to actual Rational choice, and the pressure difference of cylinder inner carrier upper and lower provides effective thrust, by piston rod, withstands connecting rod.
(2) accumulator: free G﹠O is arranged in the accumulator, be provided with top accumulator and bottom accumulator, the two cooperates regulates volume of air in the accumulator, thereby changes pressure, and then gas pressure intensity in the regulator solution cylinder pressure.
(3) gas cylinder: provide air to accumulator, increase or the corresponding gas pressure intensity that reduces or increase the accumulator that is attached thereto of less gas cylinder number meeting.Should according to actual needs, the gas cylinder number of fair amount be set.
(4) cut-off valve: consider to adapt to different pipe laying radiuses, and pipelaying work, pipe abandon, certainly deposit and the operating mode such as navigation, total gas cylinder quantity should be enough, but in the actual mechanical process, the gas cylinder number that link to each other with each accumulator by cut-off valve control.
3. the equipment of a kind of Novel supporting pipe support of the present invention Motion Compensation has following effect:
(1) oil hydraulic cylinder of motion compensating system is vertically laid and can be increased effective force among the present invention, reduces the side direction component of force as far as possible.Two ends link with connecting rod and stern truss structure respectively, and connecting rod and oil hydraulic cylinder turn round flexibly.
(2) the present invention is easy and simple to handle, only need to adjust rational oil hydraulic cylinder zero-bit pressure according to different pipe laying radius and operating modes, just can guarantee oil hydraulic cylinder stroke and stressed all at its ability tolerance range and so in the process of motion.
(3) present invention can be implemented in the process that pipe support rack moves up and down, the variation of the power on the hawser that connects pipe support rack is alleviated in the motion of compensation pipe support rack simultaneously.Therefore when selecting hawser, can suitably reduce specification, reduce expenses.
(4) Applicable scope of the present invention applicable to different pipe laying radiuses, and pipelaying work, pipe abandon, is deposited and the operating mode such as navigation extensively and flexibly certainly.
Description of drawings
Fig. 1 is detailed composition schematic diagram of the present invention, has only expressed an oil hydraulic cylinder and attachment portion thereof among the figure, and concrete oil hydraulic cylinder quantity should be decided on actual conditions.
Fig. 2 is mounting point of the present invention.
Fig. 3 is structural representation of the present invention.
The present invention is further described below in conjunction with drawings and Examples.
Embodiment
The concrete implementation methods of the present invention may further comprise the steps:
(1) design according to actual needs the rational pipe support rack motion compensating system of a cover, comprise oil hydraulic cylinder 1 quantity and size, top accumulator 2 sizes, bottom accumulator 3 sizes, gas cylinder 4 quantity and size, cut-off valve 5 arranges etc., referring to Fig. 1.
