Definitions
- the present invention is related to subsea pipeline inspection technologies. More particularly, the present invention relates to flexible duct flood detection systems.
- the submarine production systems projects in the Santos Basin Pre-salt are based on the use of collection systems using different submarine pipeline concepts, using rigid pipelines, hybrid pipelines (composed of combinations of rigid and flexible pipelines) and, mainly, flexible pipelines, which represent over 90% of the total hydrocarbon collection pipelines installed in the Pre-Salt Pole.
- the use of flexible ducts due to the high levels of C0 2 in the pre-salt, has been presenting restrictions due to the corrosion phenomena under stress by C0 2 .
- a first available technique is one that considers the injection of nitrogen or the realization of a vacuum from the safety valve for pressure relief, installed in the connectors of the flexible ducts. This method, however, is limited to the top risers (flexible duct section connected to the production unit), and requires precise knowledge of the free volume of the annular duct, as well as precise control of the volume of injected gas. Although quite applied, this method sometimes leads to dubious and questionable results.
- the document BRPI0909162 is related to an ultrasonic scanning device for inspection of a pipeline, the inspection being able to identify annular flooding of pipelines.
- US9784716B2 discloses a technique for assessing the integrity of a duct section, such as submarine flexible duct, by means of a probe comprising an ultrasonic system. Although not explicit in the title of this patent, the entire description goes back to an inspection carried out by the tubular body of the ducts.
- the document US8668406B2 reveals another method of inspection of flexible ducts through a technique that uses electrical principles.
- the method allows the determination of the nature of an interface layer (solid, liquid or gas), located between an external duct layer and an internal duct layer, by reading the polarity of the reflected signal.
- This system is a system that uses electromagnetic principles, that is, its performance does not depend on the multiple interfaces, but only on the distance between the sensor and the layer of interest (metallic reinforcement of the flexible) or even the medium (substances present not cancel). This system is under development and therefore is not yet in the commercial phase for application in the field, which also makes its application unfeasible for the Brazilian pre-salt reality.
- the object of the invention is an inspection system capable of identifying the presence of water in the annulus of a flexible duct in operation, especially in flexible ducts in operation at high depths, which represents a scenario of high pressure hydrostatic.
- the present invention aims to solve the problems of the state of the art described above in a practical and efficient way.
- the purpose of the present invention is to provide a flexible duct flooding detection system and method that can be used reliably in flexible ducts in use at high depth and high hydrostatic pressure.
- the present invention provides a flood detection system in a flexible duct from a flexible duct connector comprising: an ROV comprising an arm element adapted to move an ultrasonic sensor, until the ultrasonic sensor is in contact with the flexible duct connector; and means for performing ultrasonic measurements with respect to the status of the flexible duct annular from a flexible duct connector chamber in contact with the flexible duct annular.
- the invention further provides a method of detecting flooding in a flexible duct from a flexible duct connector comprising the steps of: moving an ROV to a region close to the flexible duct connector; activate an ROV arm element to move an ultrasonic sensor, until the ultrasonic sensor is in contact with the flexible duct connector; and conducting ultrasonic measurements with respect to the status of the flexible duct annular from a flexible duct connector chamber in contact with the flexible duct annular.
- Figure 1 illustrates a schematic view of the flood detection system in a flexible duct from a flexible duct connector, according to a particular configuration of the present invention.
- Figure 1 illustrates a schematic view of the flood detection system in a flexible duct from a flexible duct connector, according to a particular configuration of the present invention.
- the flood detection system in a flexible duct 17 from a connector 14 of flexible duct 17 comprises: an ROV3 comprising an arm element 18 adapted to move an ultrasonic sensor 13, until the ultrasonic sensor 13 is in contact with the connector 14 of the flexible duct 17; and means for performing measurements with respect to the status of the flexible duct annular 17 from a flexible duct connector chamber in contact with the flexible duct annular.
- a method of detecting flooding in a flexible duct 17 is also provided from a connector 14 of the flexible duct 17, associated with the system described above, comprising the steps of: moving an ROV3 to a region near flexible duct connector 14; drive an arm element 18 of the ROV 3 to move an ultrasonic sensor 13, until the ultrasonic sensor 13 is in contact with the connector 14 of the flexible duct 17; and making measurements with respect to the state of the flexible duct annular 17 from a chamber of the connector 14 of the flexible duct 17 in contact with the annular of the flexible duct 17.
- the ROV 3 can be connected to a control device 1 (such as a computer) adapted to manage the other electronic elements of the system.
- a control device 1 such as a computer
- the ROV3 can comprise a pressure vessel 6 internally comprising an ultrasound device 5, where the ultrasound device 5 / is connected to the ultrasound sensor 13.
- the ultrasound sensor 13 sends the received information to the ultrasound device, which handles the received information and sends the processed information to the control device 1.
- the control device analyzes the information to define the state of the annular of the flexible duct 17, from the information of the connector 14.
- the ultrasound technique is based on the principle that a wave transmitted by a sensor 13 in a first medium is partially reflected and partially transmitted when it encounters the interface of a second medium.
- the proportionality between reflection and transmission will depend on the difference in acoustic impedance between the media.
- the connector chamber 14 of the flexible duct 17 in contact with the annular of the flexible duct 17 will also be dry.
- the means that the ultrasound of the present invention will pass through are steel (connector) and air (flexible duct connector chamber in contact with the annular flexible duct), with most of the signal reflected in the interface.
- the chamber of the connector 14 of the flexible duct 17 in contact with the annular of the flexible duct 17 will also be flooded.
- the means that the ultrasound of the present invention will pass through are steel (connector) and water (flexible duct connector chamber in contact with the annular flexible duct), being part of the reflected signal and part of the transmitted signal .
- This part of the transmitted signal meets the next surface / interface which can be water with steel from the slip ring or water with resin.
- the part of the signal transmitted at the first interface it is now reflected in the second interface and returns to the sensor.
- the display of the device optionally, has a graph called A-Scan that represents the signals in space or in time where these reflections occur.
- the processing of data is done observing where these reflections occur, and they are different in the conditions of annular dry and flooded.
- Control device 1 can be connected by cabling 2 to the remote operating vehicle (ROV 3).
- Umbilical cable 4 from ROV 3 can be connected to the ultrasound device 5 installed inside the pressure vessel 6.
- the connector 7 of the ROV umbilical 3 and the connector 8 of the pressure vessel 6 can be any known in the state of the art, and which have the necessary characteristics for each application, in which these do not represent limitations for the scope of protection of the present invention.
- the umbilical 4 of the ROV 3 can provide routes for both electrical energy (power) and routes for transmission of inspection data.
- An internal cable 9 to the pressure vessel 6 must interconnect the connector 14 and the ultrasound equipment 5.
- the ultrasound equipment (inside the pressure vessel 6) must be connected to the ultrasound sensor 13.
- a second internal cable 10 must connect the ultrasound equipment to a second connector 1 1 on the pressure vessel 6.
- Another cable12 must connect the connector 1 1 on the pressure vessel6 to the ultrasound sensor13 connected on the other end of this cable 1 1
- This cable 1 1 can be submarine or a conventional cable surrounded by a pressure compensated hose.
- the ultrasound sensor 13 must be approached to the connector14 using the resources of the ROV 3 to carry out the measurements regarding the state of the annular of the flexible duct 17.
- a luminous device 16 coupled to one of the accesses of the gas relief valves (or plugs).
- the luminous device 16 is adapted to light up when the chamber of the flexible duct connector in contact with the annular of the flexible duct is filled with water from the flooding of the annular space.
- the system of the invention optionally provides that the flexible duct connector comprises a device15 adapted to allow ultrasound inspection by identifying the presence of liquid in the chamber of the flexible duct connector 14 in contact with the annular of the flexible duct 17.
- the device 15 can be defined by any subject matter, so that it does not limit the scope of the invention.
- device 15 is in communication with a luminous device 16 positioned externally to connector 14.
- a signal A light alert can be issued, visually indicating the need to verify the integrity of the annular flexible duct.
- the light alert described is part of an additional system independent of ultrasound. These systems are complementary and redundant, but independent. In an optional practical application, the ultrasound inspection can only be carried out if the light system comes on.
