    Marine research usually uses geophysical sensors below the surface of the water, for example in the form of long cables of marine flute towed behind a boat, or cables at the bottom of the ocean resting on the bottom of the sea. 'ocean. Conventional marine research flute cables can often be 12 kilometers long, and can include hundreds, or even thousands, of geophysical sensors. Several of these streamers are often positioned or towed in parallel over a search area. Seismic and electromagnetic sources are also often attached to cables for towing or positioning on the ocean floor. The term "research cable" is used here generically to cover all types of submerged cabling used for marine research including, but not limited to, tow cables for geophysical sources, flute cables marine, and traction cables for the source / sensor row.
    Marine searches often take weeks or months, which is more than enough time for search cables to attract barnacles and other unwanted living things or debris.
    These materials tend to increase the drag of the cables, thereby requiring a greater amount of towing energy and applying increased stress to the boat, cables, and positioning devices. This material can also induce additional turbulence, which can alter the quality of the data captured by the sensors distributed along the cable. Current methods of cleaning research flute cables tend to be lengthy and labor intensive.
    Therefore, the present invention provides in a first aspect a research cable cleaning tool which includes a scraper mechanism configured to clean debris from a research cable deployed in a body of water; and a cable guide configured to lift the search cable out of the body of water and to guide the search cable into the scraper mechanism as the tool moves along the search cable.

    A better understanding of the various embodiments of the disclosed system and method can be obtained when the following detailed description is considered in conjunction with the drawings, in which:
    Figure 1 is a side elevational view of an exemplary marine search system during a cleaning operation;
    Figure 2 is a top plan view of the marine research system of Figure 1;
    Figs. 3A and 3B are side and top views, respectively, of a first embodiment of a research cable cleaning tool;
    Figs. 4A and 4B are side and top views, respectively, of a second embodiment of the research cable cleaning tool;

    Figures 6 to 8 show steps of an example of a scraper blade mechanism passing over a connector; and
    Figure 9 is a flow diagram of an exemplary cable cleaning method.
    The problems identified in the background are at least partially addressed by sophisticated tools and methods for cleaning research cables from a work boat traveling the length of the cables. At least some embodiments of the tools can be easily mounted on the work boat and be positioned in operating relation around the search cable. In addition, at least some implement embodiments are designed to require less labor to operate and maintain them, and to at least partially automate the cleaning process with a hydraulic motor or a friction belt which controls the speed of rotation of one or more scraper wheels in relation to the speed at which the work boat travels along the cable. A spring system, and in some embodiments a release lever, can be used to allow automatic manipulation of connectors, steering devices, or other elements having an enlarged profile relative to the main cable. With the current industry trend toward longer and thinner marine streamers due to geographic and operational advantages, these cleaning tools can facilitate faster and more efficient cleaning of research cables.
    The disclosed systems and processes will be better understood in the context of an appropriate usage environment. Therefore, Figure 1 shows an example of a marine geophysical research system 10 during cleaning. A research vessel or vessel 12 travels along the surface of a body of water 14, such as a lake or an ocean. The search system 10 comprises a data recording system 18 on board the boat 12. The search system also includes a geophysical source 20 and a row of sensors 22 towed into the water 14 by the boat 12.
    Figure 2 shows the marine geophysical research system 10 from above. Referring to Figures 1 and 2, the array of sensors 22 includes multiple spaced apart sensor units integrated into one or more marine research streamer cables 24A through 24D to detect geophysical signals and generate signals Corresponding output for collection and storage by the data recording system 18. The marine research streamer cables 24A to 24D can be towed through a towing assembly which produces a desired arrangement. Such a tow assembly may include multiple interconnected cables and a pair of controllable line divers 30A and 30B connected to opposite sides of the tow assembly. When the boat 12 tows the towing assembly in the water 14, the line divers 30A and 30B pull the sides of the towing assembly in opposite directions transverse to a direction of movement of the boat 12. Electrical conductors and / or fiber optic cables connect the sensor units in the streamer sections of the marine research streamer cables 24A to 24D to the data recording system 18 on board the boat 12. Other overall configurations tow and cable can also be used.
    Marine research flute cables can be designed with a modular construction such that each marine research flute cable is formed by connecting multiple sections of marine flute end to end. Such a modular construction, for example with substantially identical and interchangeable sections, considerably simplifies handling, maintenance and repair. If a problem develops with one of the streamer sections, the problematic streamer section can be easily replaced with any other spare streamer section. The connectors between the streamer sections include terminal parts (eg, sockets and pins) which connect the communication passages of the different streamers in a long communication structure for the marine research streamer cable.
    During normal operation of the illustrated system, the geophysical source 20 produces acoustic waves 32 at regular intervals or in selected locations. The geophysical source 20 can be or comprise, for example, an air gun, a vibrator, or another device. The acoustic waves 32 move in the water 14 and in the formations below the surface 36 below a bottom 34. When the acoustic waves 32 encounter changes in the acoustic impedance (for example at the limits between the strata), part of the wave energy is reflected. In FIG. 1, the radius 40 represents the wave energy reflected in a particular direction by the interface 38. The signals recorded from the sensor units can be interpreted later in order to deduce therefrom the structure, the content in fluid, and / or the composition of rock formations in the subsurface 36.
    Periodically, it may be desirable to clean the research cables such as, for example, the marine research flute cables 24A to 24D. FIGS. 1 and 2 show an example of a work boat 42 moving along the length of a marine research flute cable 24A in the same direction as the movement of the ship 12. When the work boat 42 moves on the length of a streamer, it lifts and cleans the streamer with a cleaning tool attached to the side of the work boat.
    Figures 3A and 3B are side and top views, respectively, of a first embodiment of a cleaning tool suitable for cleaning a search cable 302. This embodiment uses a cable guide 305 with a roller mechanism 306 which lifts the research cable out of the water and guides it through a scraper mechanism 311. The roller mechanism illustrated 306 is a friction belt which rotates in response to the movement of the research cable through the cable guide, but other suitable roller mechanisms include wheels, pulleys, and rollers. Side walls 307 (Figure 3B) help trap the search cable 302 on the roller mechanism and help guide the cable into the scraper mechanism, which can be mounted on the cable guide via a plate rigid side 309, or by other means as further described below. Bars 308 may be provided on the side walls 307 or elsewhere on the cable guide 305 to serve as handles for personnel to use it when mounting the cleaning tool on the side of the work boat.
    When the cable guide 305 lifts and passes under the search cable, the cable exerts a friction pull on the roller mechanism 306, which causes it to rotate at a speed corresponding to the speed of the cable relative to the boat of work. The roller mechanism 306 is connected via a belt drive system 304 to rotate a set of scraper wheels 310. The scraper wheels 310 have short bristles of plastic, wire, or another material chosen for its effectiveness in removing barnacles without significantly eroding the surface of the research cable. When the roller mechanism 306 rotates, it rotates the scraper wheels 310 so that they rotate against the movement of the search cable 302. The ratio between the speed of rotation of the roller mechanism 306 and the speed scraper wheel rotation
    I
    310 is established by the design of the belt drive system 304 and can be adjusted by changing the relative diameters of the pulley wheels in the belt drive system.
    The scraper wheels can be positioned in pairs on each side of the search cable 302. In the embodiment of Figures 3A and 3B, a first pair 310a is on the top and a second pair 310b is on the bottom. Elastic arms (e.g. spring loaded) 312 can keep the scraper wheel pairs in contact with the search cable while still allowing the wheels to move apart for, for example, connectors, positioning devices, or other areas of the search cable with an enlarged profile. Arm extensions may be provided in the form of handles 318 which personnel use to separate the arms 312 when, for example, positioning the scraper wheels around the search cable. Springs 316, hydraulic elements, or other elastic mechanisms can be used to hold the arms 312 and the wheels 310 in position around the cable. The tensions of the elastic mechanisms can be adjusted to allow the scraper mechanism 311 to accept different sizes of search cable.
    Each pair of scraper wheels 310a, 310b can be flexibly mounted with a support 314 which pivots to allow a certain degree of independent movement for the two scraper wheels in each pair so that, for example, the wheels can each follow changes in the cable profile and / or accept a certain irregularity in the speed of wear for the front and rear wheels. The scraper wheels rotate to remove the barnacles and other unwanted debris that have settled on the search cable.
    In at least some embodiments, the scraper wheels 310 are configured to be easily interchangeable without the need for tools. The handles 318 allow the arms 312 to be easily opened and removed from the search cable. When they are away from the cable, the supports 314 can be provided to have a certain free play so that, with the withdrawal of the axle for the wheels 310 or, in certain embodiments, of the pivot axis for supports 314, the worn wheels can be replaced by spare wheels. In some embodiments of the tool, the handles 318 are also removable to keep them clean while the cleaning tool is in operation. The handles 318 can slide in and out of bases in the arms 312.
    Figure 3B illustrates a top view of the cleaning tool of Figure 3A. As the work boat 42 travels the length of the search cable 302, the search cable 302 is pulled from left to right above the roller mechanism 306. The roller mechanism 306 rotates when the cable 302 is pulled through the tool and spins the scraper wheels 310 against the direction of cable movement. This direction of rotation provides more vigorous scraping of the cables, which is considered a more optimal cleaning process. The scraper wheels 310 peel off the barnacles and unwanted debris from the search cable.
    FIGS. 4A and 4B illustrate a second embodiment of a cleaning tool intended to clean a research cable 302. As in the previous embodiment, the cleaning tool can have a cable guide 305 (FIG. 4B) intended to lift and guide the search cable 302 through the scraper mechanism
    311 when the work boat moves along the length of the search cable. The cable guide may include a roller mechanism 306 and side walls 307 as before, although some alternative embodiments may use a plastic or metal slide rather than a roller mechanism to lift and guide the cable research 302.
    In the embodiment illustrated in Figures 4A and 4B, the scraper mechanism 311 is actuated by a hydraulic motor 406, although other types of motor can also be used. The motor 406 rotates the scraper wheels 310 via the belt drive system 304. As before, the scraper wheels 310 can rotate against the direction of movement of the search cable through the tool to remove barnacles and other debris.
    The scraper mechanism 311 does not need to be rigidly connected to the cable guide 305, and in the illustrated embodiment, it is fixed with two chains or cables 405. The chains 405 provide additional flexibility for the mechanism of scraper 311 are oriented around the search cable 302, possibly taking the wave movement of the work boat if necessary. Such a connection also reduces the size and weight of the cleaning tool, which makes it easier to operate the tool.
    In addition to, or in place of the scraper wheels 310 discussed above, the scraper mechanism 311 may use one or more scraper blade devices as shown in Figures 5 to 8. One or more of these scraper blade can be fixed on a frame for the scraper mechanism 311, or can be directly mounted on the cable guide 305. Referring to Figures 5 and 6, the scraper blade device comprises a housing for blade 502 with a retractable scraper blade 514 and a set of one or more springs 508 which support the blade 514 against the search cable 302 or, in the absence of search cable 302, support the blade up to the complete extension allowed by the lever 520 and the housing 502. A hole or recess 513 in the blade 514 receives a lever extension 528 which fixes and, when necessary, retracts the blade 514 in the housing 502. A slot 504 in housing 502 defines the range of movement of the lever from the position shown in Figure 6 to that shown in Figure 7. One or more ventilation holes 506 may be provided to allow air and / or other fluids easily escape from the housing 502 when the blade 514 moves.
    The lever 520 is fixed on two pivot point flanges 515 on the housing 502 by means of a quick coupling (in this case a bolt 516 retained by a split pin 518). The pivot point flanges 515 enclose the lever 520 to provide support while allowing the lever to pivot around the bolt 516. A lever extension 528 is positioned in the slot 504, which has upper and lower edges which limit the extent on which the lever 520 can pivot on the bolt 516. It should be noted that the blade replacement can be easily carried out by removing the quick coupling and pulling the lever 520 from between the pivot point flanges 515, thereby removing the lever extension 528 from the recess 513 in the blade 514. This withdrawal frees the blade 514 in order to slide out of the housing 502 so that it can then be replaced. The replacement blade 514 is pressed into the housing 502 against the return springs 508 until the recess 513 aligns with the slot 504 and the lever extension 528 can be reinserted into the recess. The lever 520 is then fixed again by the quick coupling.
    The housing 502 is positioned such that the scraper blade 514 is configured to press against the surface of the research cable 302 when the cable passes through the tool. Other scraper blade devices can also be positioned in different orientations around the cable to ensure that the entire circumference of the cable can be cleaned by the tool. The end of the blade 514 may have a contoured shape, such as an arc of a circle sized to match the cable profile, so as to reduce the number of scraper blade devices required to effectively clean the cable.
    Figures 6 to 8 show an example of how the scraper blade device can pass over a connector or other part of the research cable having an enlarged diameter. In FIG. 6, the springs 508 have fully extended the scraper blade 514 in order to come into contact with the surface of the search cable, and the lever 520 is in a rest position. The lever projection 524 is positioned to meet all the enlarged profiles with an inclined front edge 526. When the cable moves through the cleaning device in direction 512, one or more connectors 510 are liable to pass through the device, with a front edge 530 which contacts the lever projection 524 and pivots the lever 520 around the bolt 516 as indicated by the arrow 532. When the lever 520 pivots, the lever extension 528 moves towards the high in the slot 504 in order to retract the blade 514 away from the connector 510.
    FIG. 7 shows the scraper blade mechanism when the connector 510 passes under the retracted blade 514. The front edge 530 has moved the lever projection 524 in the direction of movement of the search cable 512, thereby bringing the projection 524 to rotate away from the search cable. The enlarged profile of
    5 510 connector maintains the projection 524 in this position to maintain the blade 514 retracted when the connector goes. The figure 8 watch the mechanism blade of scraper when connector 510 moving in the 10 direction 512 moves apart projection 524. In this position, the springs 508 support the blade 514
    initially against the enlarged profile of the connector 510 and, when the connector 510 moves away, against the normal profile of the search cable. When the blade 514 returns to its extended position (Figure 6), the lever 520 returns to its rest position with the lever projection 524 positioned so as to detect all of the following connectors.
    The blade material can be selected to minimize abrasion of the cable surface while providing effective cleaning action. The blade can be made of polytetrafluoroethylene (eg Teflon®) or another rigid plastic which provides effective cleaning with minimal abrasion of the cable surface. Other blade materials may also be suitable, including wood and metal, provided care is taken to round the edges in order to minimize any risk of cutting the surface of the research cable.
    Figure 9 shows an example of a search cable cleaning process. In block 902, a scraper mechanism such as a set of scraper blade devices or a set of scraper wheels is attached to a cable guide, which is then mounted on a work boat in block 904. In block 906, a crew positions the cleaning tool in a functional relationship on the research cable, for example by lifting the cable in position on the cable guide and by separating the elastic arms in order to place the research cable between the wheels / scraper blades.
    With the cleaning tool in position, the crew guides the work boat along the length of the search cable as shown by block 908. When the work boat moves the cleaning tool, the roller mechanism or the guides in the cable guide raise the search cable to or above the water surface in block 910 to facilitate monitoring of the cleaning process. The cable guide further guides the search cable through the scraper mechanism which uses scraper wheels and / or scraper blade devices to remove debris from the cable. As previously described, the scraper wheels can be driven by the roller mechanism or a motor to rotate against the movement of the cable through the cleaning device. In block 914, connectors or other parts of the enlarged profile of the cable are accepted by the elastic arms or the retractable blades in the scraper mechanism. Blades can be retracted by levers that detect the leading edge of the connectors, while scraper wheels can be configured to move apart from one another on elastic arms. Such automated operation can facilitate cleaning.
    Other variations, equivalents, and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. For example, the belt drive system may be supplemented or replaced by a gear transmission designed to provide the scraper wheels with a desired and / or variable rotational speed.
