Definitions
- the present invention relates to a plant for manufacturing a rigid pipe for deep water suction within an offshore platform.
- This pipe is used for the production of offshore electric power as part of the thermal energy of the seas.
- An energy production facility of this type generally comprises a platform on which electrical energy generation means are loaded from the difference in temperature of the water at the surface and at depth, this platform being furthermore associated with means forming a deep water suction pipe.
- ETM Thermal Energy of the Seas
- the water may for example be at a surface temperature of 25 ° and a temperature of 5 ° C to 1000 meters deep.
- the water must then be pumped in very great depth through suction pipe means associated with the platform, while the hot water is pumped to the surface.
- the object of the invention is therefore to solve these problems.
- the subject of the invention is a plant for manufacturing a rigid pipe for deep water suction for a thermal energy installation of the seas, characterized in that it comprises a floating platform on which are implanted means of continuous production and vertical axis of the pipe and comprising:
- the plant for manufacturing a rigid suction pipe comprises one or more of the following features:
- the pipe comprises a helical external rib adapted to cooperate with guide means of the fifth guide stage and control of the descent to control the descent of the pipe into the water,
- the protection means comprise a cover
- the second stage of complete crosslinking of the resin comprises means for heating the pipe.
- this figure shows a part of a plant for manufacturing a rigid pipe for deep water suction which is intended to be used in a thermal power plant of the seas.
- this plant for manufacturing the rigid pipe comprises a floating platform designated by the general reference 1, on which are implanted means for continuous production of the suction pipe, these means then making it possible to produce vertically and continuously, a pipe of composite material, fiber-resin, large diameter for example between 4 and 12 meters per filament winding.
- These manufacturing means are designated by the general reference 2 in this figure and comprise a number of stages among which a first winding stage of the fibers and pre-cooking of the impregnating resin, designated by the general reference 3 .
- This stage then comprises different filament winding heads around a mandrel designated by the general reference 4 in this figure, implementing for example the technique of the mandrels known as "DROSTHOLM" consisting in fact in a cylindrical surface for receiving the tablecloth filament winding, advancing axially spirally to drive these plies and thus forming the wall of the pipe, this surface up through the inside of the mandrel to renew itself in the upper part, in a manner known per se.
- DROSTHOLM the technique of the mandrels
- This mandrel is then adapted to drive in a second so-called postcure stage and complete crosslinking of the resin, this second stage being designated by the general reference 5 and comprising heating means 6 to obtain cooking desired resin.
- the pipe passes into a third stage said fixing functional organs such as appendices and helical guide means for example to fix on the outer wall of the pipe thus formed, a helical rib forming a screw whose function will be described in more detail later.
- said fixing functional organs such as appendices and helical guide means for example to fix on the outer wall of the pipe thus formed, a helical rib forming a screw whose function will be described in more detail later.
- This third fixing stage is designated by the general reference 7 in this figure, while the helical rib is designated by the general reference 8.
- the pipe passes into a fourth floor called security anchoring and material control, designated by the general reference 9, in which a number of checks of the integrity of the pipe are made.
- the pipe passes into a fifth stage of support, guidance and control of the descent thereof, this stage being designated by the general reference 10 in this figure and then comprising guide means designated by the general reference 1 1, through which passes the pipe and in particular the helical guide rib thereof to control the descent of the pipe.
- the pipe then crosses the platform 1 to descend into the water as designated by the general reference 12 in this figure, sunlight masking means being provided for example between the lower part of the platform 1 and the water to avoid any degradation of the pipe.
- These masking means are designated for example by the general reference 13 and are for example in the form of a protective cover.
- Grid or strainer means may also be provided at the lower end of the pipe, these means being designated by general reference 14 in this figure.
- the first ply of fibers is then wound on this surface and it is driven down by the mandrel strip.
- the sheet is 1 meter wide and if the mandrel consists of a spiral that goes down 1 meter per turn, the sheet also drops 1 meter per turn. After a turn, she finds the initial winding without overlapping. During this turn it also drops 10 centimeters every tenth of a turn. If there are ten winding stations on a tower, the sheet falling down 10 centimeters every tenth of a lap is then covered with another band of fibers and its upper part has received ten layers of fiber on the complete turn. It is thus linked to other layers without significant discontinuity.
- a lathe then makes it possible to obtain 5 millimeters of wall thickness with fabrics of 600 grams per square meter.
- the first crosslinking is carried out during the deposition of each sheet so as to subsequently avoid excessive exothermicity because of the substantial wall thicknesses of the order of 100 mm envisaged in the end.
- the crosslinking will for example reach a maximum of 30%.
- We will have dissipated 30% of the total exotherm without stiffening too much the network of macromolecules so that the sheet conforms well to the curvature of the surface and adheres to the previous one.
- this state of immediate pre-polymerization gives access to compaction of the surface by pressure rollers, boilers, etc.
- this state of intermediate crosslinking is completed to about 60% and gives an initial rigidity for maintaining the wall, which then makes it possible to dispense with the support of the mandrel. It is released gradually and back through the inside of this mandrel.
- the post-baking stage must lead to complete crosslinking of the resin by heating from outside and from inside the pipe. This complete crosslinking is necessary to prevent the aging of the material by taking up moisture. At this level only 30% of the energy to be dissipated remains.
- the ratio between the energy generated by chemical reaction and dissipated by the thermal pipe is the number of "DAMKOHLER". It must remain below 1 to prevent temperature runaway, and destruction of the wall of the pipe of the tube up to the explosion of the stack.
- the fine control of the crosslinking is therefore inseparable from the temperature to ensure the realization of such a wall thickness.
- the rotation speed is a control parameter.
- Attaching support appendages or equipment comes in the continuity of the previous cooking.
- an additional raceway of rollers will help support the pipe and help to drive it in rotation.
- the variation of the pitch of this propeller can take into account the mass of the tube which increases during manufacture. This path can reversibly go up part of the tube if the lamination is not correct or if the wall must be corrected.
- the production control is exercised on the resin and fiber components up to the final structure.
- the acid value can be controlled because a value that is too high leads to incomplete crosslinking, the supplied resin then being poorly prepared.
- the control of the fibers concerns for its part a control of the weights and the mechanical integrity of the tissues.
- the supplied fiber rolls include a bonding method for quickly bonding two fabrics per lap.
- the polymerised material can also be controlled because for all materials and components used in the manufacture of the pipe, it must be ensured that the minimum values of the defined properties are respected by carrying out tests.
- possible non-destructive testing methods for these assemblies can be:
- BARCOL hardness test
- the crosslinking is correct when the material has a satisfactory hardness, for example greater than 40. Only the surface is accessible. Wall cores are to be expected at the end of crosslinking.
- DSC digital signal processing
- the temperature must not be less than 15 ° C and greater than 40 ⁇ . As mentioned above a temperature of the order of 40 ° allows a pre-crosslinking of the resin by dissipating a portion of the energy and to limit the exotherm in the case of realization of high thicknesses that is to say greater than 30 mm.
- a high ambient temperature causes a faster reaction of the resin. It is possible to modulate the reaction time by adding retardants in the resin.
- the physicochemical characterization in reactivity allows the control of these data.
- the storage time leads to a degree of cooking of the order of 10%.
- the ambient humidity must also be less than 80%.
- the porosities expected by the energy absorption are also not too troublesome character as in the case of thin parts, the latter not being subjected to planar shear or transverse as a whole.
