Description
SPECIFICATION
Underwater electrical cable connectors
This invention relates generally to seismic surveying, and more particularly to underwater electrical cable connectors for marine seismic surveying of subsurface geological conditions.
In seismic surveying in a medium such as water, acoustical energy is generated by air guns submerged in the water. The generated acoustical energy is used to investigate subsurface geological conditions and formations. One or more air guns are submerged in thewaterand compressed air, or another suitable pressurized gas, is fed to the submerged guns and temporarily stored. At a desired instant, the seismic source airguns are fired, abruptly releasing the stored pressurized gas into the surrounding water, producing powerful acoustic waves. The acoustic waves penetrate deeply into subsurface materials and are reflected and refracted by the various strata and formations in the subsurface material. The reflected or refracted acoustic waves are then sensed and recorded to provide data about the geological conditions and formations.
To provide a composite acoustic wave of satisfactory amplitude and frequency content, a pluarality of acoustic waves are generated from an array of air guns. Air guns having varius volume capacities have been used in such arrays to produce a composite acoustic wave having a broad frequency band, as guns of different volume generate acoustic waves with different frequency spectrums.
The individual guns in the array must be fired in a prescheduled preciselytimed relationship to provide optimum survey results. For example, if each of the air guns are to be fired in synchonism, and they are not so fired, the seismic waves produced bythe guns are misaligned. Such misalignment may cause a reduction in the total amplitude of the generated seismic waves, or may cause the generation of seismic waves with undesirable frequency spectra, resulting in seis micwaveswith reduced penetration and hence collected data with reduced resolution.
In conventional systems, a firing signal is applied to a solenoid in each gun to fire the gun. A suitable transducer responsive to the acoustic wave generated bythe gun senses gun firing and provides a small electrical signal indicative of the instantthe gun was fired. The electrical signal produced by each gun is then fed hack to ci rcuitry which processes the signals received and delays or advances the timing of the triggering signal transmitted to each gun such that each gun fires in synchronism.
The triggering signal and the fed back electrical signal is transmitted between the processing circuit and the airgun overran electrical cable. A pair of cable connectors couplethecableto the airgun, the airgun typically being disposed some twenty to thirty feet underwater in a saltwater environment. The connector is typical!y located within three feet of the air gun, and is subjected not only to hydrostatic pressure, but to a blast pressure from 4to 6 bars at one meter with each blast of the air gun. Typically, each blast of each air gun is equivalent to 100 grams of TNT.
Typically in marine seismic exploration operations, the air guns are each fired everyten seconds for many days and sometimes weeks at a time. Such a rigorous firing schedule subjects the connectorto a continuous bombardment of some 8,640 blasts per day, each equivalent to 100 grams of TNT. Notwithstanding, repeated pressure bomba rdment and the hostile salt water environment, the processing circuit located above water must transmit typically a 100 volt trigger pulse to each air gun located underwater, and the air gun must transmit backto the processing circuit typically a one voltfeedback pulse within one millisecond, and ideally within one-half millisecond of air gun firing. This process must be repeated every ten secondsfordaysorweekson end.
The air guns are rather durable, having a life of some ten to fifteen years, and requiring overhaul every 40,000 to 60,000 shots. The electrical cable itself typically includes a polyurethane cable jacket and can be rendered suitably waterproof. The weakest elements in the system arethe cable connectors used to connectthe electrical cable to the air gun.
Conventional connectors have a relatively short life due to exposure to the salt water environment and exposure to the pressure waves generated by the air guns. Electrical leakage occurs between individual connectors in each cable connector. Such leakage rapidly deteriorates the integrity ofthe one volt feedback signal transmitted by the air gun and needed by the processing circuit to properly synchronize each airgun inthearray.
Yet further, the configuration required in typical underwater electrical connectors to minimize leakage and prolong life prevents the inclusion of a large number of individual pin connectors in any one cable connector. Known conventional cable connectors include onlytwo orfour pin connectors.
Thus, there isa needforan underwater electrical cable connector capable of prolonged use in a hostile salt water environment when subjected to repeated exposureto powerful blasts of pressure, capable of transmitting without leakage a high voltage, high current pulse of short duration to an air gun located underwater, and capable offeeding backfrom the air gun to processing circuits located above water a relatively lowvoltageshort duration feedbackpulse indicative of gun firing.
According to the present invention,there is provided a mating pair of underwater electrical cable connectors for a multiconductor underwater electrical cable connecting a marine seismic source for investigating subsurface geological conditions to a survey vessel towing said seismic source, said mating pair of electrical connectors comprising: a first member which includes a first body member, at leasttwo electrical pin connectors mounted in said body member, each of said pin connectors being adapted to be electrically connected to an electrical conductor of a first underwater electrical cable, and at leasttwo pin insulator receptors, each of said receptors extending inwardly into said first body member and being disposed coaxially about one of said electrical pin connectors; and a second memberwhich is adapted to mate with said first member and which includes a second body member, at least two electrical pin receptors projecting outwardlyfrom said second body member and adapted to mate with said at leasttwo electrical pin connectors, each of said pin receptors being adapted to be electrically connected to an electrical conductorofa second underwater electrical cabie, and at least two pin insulators adapted to mate with said pin insulator receptors, each of said pin insulators being disposed coaxially about one of said pin receptors; and sealing structure adapted to render watertight the pin insulator-pin insulator receptor connections.
The invention also provides an underwaterelectrical connectorfor a multiconductor underwater electrical cable connecting a ma ri ne seismic sou rce to a survey vessel towing said source, said connector comprising a body member, at leasttwo electrical pin connectors mounted in said body member, each of said connectors being adapted to be electrically connected to an electrical conductor of said underwatar electrical cable, at least two pin insulator receptors, each of said receptors extending inwardly into said body member and being disposed coaxially about one of said electrical pin connectors, and sealing structure included on said body member.
The invention further provides an underwater electricalconnectorfora multiconnectorunderwater electrical cable connecting a marine seismic source to a survey vessel towing said source, said connector comprising a body membera's leasttwo electrical pin receptors, each of said receptors projecting outwarah from said Lody member and being adapted to be electrical I- connected te an electrical conductor of
said undenNaterelectric21 cable, at least two pin
insulators, each of said insulators being disposed coaxiallyalfout one of said pin receptors, and sealing structure included on said body.
The present invention enables underwater electrical cable connectors to be provided which are better abie to withstand the hostile salt water environment and the repeated pressure blasts generated by air guns.
The connector is desirably made of a special tough resilient thermoplastic polyurethane which has excellent lowteniperatureflexibilityalong with high abrasion resistance and tear strength. The cable connector is preferably moulded onto the end of the electrical cable and a waterproof bond made between the connector material and the polyurethane cable jacket.
A cable connector embodying the present invention has a relatively long life in the hostile marine environment when compared to prior art connectors; it can typically last some 1 2to 18 months subjectto the blasts of pressure and the saltwater environment.
During that period of time, it is capable of transmitting a clean one volt feedback pulse from the air gun to the processing circuitry.
A connector embodying the present invention may include 50 or more individual pin connectors. The leakage path between individual pin connectors is relatively long, that is at least two inches (5cms).
Connectors embodying the present invention can advantageously be used wherever low cost waterproof connectors are required.
The sealing structure to renderthe pin insulator-pin insulator receptor connections water-tight may in dude one or more compressible sealing members which form a water-tight seal when subject to compression. The sealing members are so designed and disposed that the pressure bombardment of the connectors by the air guns further compresses the sealing members, thereby increasing the effectiveness ofthewater-tight seal.
In one embodiment of the present invention, the sealing structure includes at least one O-ring member disposed aboutthe periphery of each pin insulator receptor. In another embodiment the sealing structure includes at least one O-ring memberdisposed about the periphery of each pininsulatorThesealing structure may also include at least one O-ring member disposed on theface of the first or second body member. The O-ring members of the sealing structure form true wiping seals and do not require mating grooves.
The invention will further be described by reference to the accompanying drawings which illustrate par ticularembodimentsofelectrical underwater cable connectors in accordance with the present invention, wherein like members bear like reference numerals and wherein:
FIG. 1 illustrates a seismic survey vessel towing a multiple air gun marine seismic survey streamer; for illustrative purposss, an enlarged detailed view is included; F1G. 2 is a cut-away perspective view of prior art underwater electrical cable connectors;
FIG. 3 is a perspective view of under'vater electrical cable connectors according to the present invention; and F & 5 are section views of the underwater electrical cable connectors of FIG. 3 taken substantiallyalong lines4-4and 5-5.
Referring now to the drawings, and in particula rto
FIG. 1, there is shown a survey vessel 10 towing a streamer ofair guns 12 by a armored towing leader 14.
Afloat device 16 is connected by a float line 18 to the air gun 12. The float device 16 and the flow line 18 maintain the air gun at a fixed distance from water line 20, typically a distance of 20 to 30 feet.
The armored towing leader 14terminates in an end bell termination 22towhich is connected a chain member 24. Each air gun 12 is mounted on a housing 26 which is connected both to the chain member 24 and to one float line 18. (See enlarged Detaii A-A of FIG.1).
An air line 28 eminentefrom the end bell termination 22, as does a plurality of electrical cables 30. One of the electrical cables 30, an electrical cable 32 is connected by an underwater electrical cable connector 34to an electrical cable 36 of the air gun 12. An air line 38 connects the air gun 12to the air line 28.
In operation, high pressure air is supplied to the respective air guns 1 through the air lines 38 from the air line 28. Each airgunwithinthestreamerisfired by an electrical trigger pulse transmitted through the electrical cables 30 and to each respective air gun 12 through the electrical cable 32, the underwater elec tricai connector 34, and the electrical cable 36. It will be appreciated by those skilled in the artthatthe individualtriggersignals are transmitted through individual electrical cables 32 which in aggregation form the plurality of electrical cables 30.
To accurately monitorthe actual firing ofthe several
air guns 12, a feedback signal is transmitted from each
air gun 12 through the respective electrical cables 36, the underwater electric connectors 34,the electrical
cables 32 which make up the plurality of electrical cables 30, through the end bell termination 22, through the armored towing leader 14 and into the survey vessel 10 where it is received and processed by suitable electronic circuitry.
To cause each ofthe air guns to fire precisely in accordance with its preselected desired timed relationship (for example, all guns firing synchronously or in a predetermined timed sequence), the processing circuitry on the survey vessel 10 advances or delays one or more of the firing signals fed to the air guns 12 to bring the instant of actual firing of each air gun into accordance with the predetermined survey plan.
Known, conventional priorartunderwaterelectrical connectors 34 are best illustrated in FIG. 2. Such connectors are typically injection molded oftough resilient thermoplastic polyurethane and typically include two orfourcontacts.
Referring to FIG. 2, a male connector 40 mates with a female connector42. Each of the connectors 40, 42 include a rotationally symmetric protruding element 44,46 having a pin receptor 48,50, and a semicircular member 52,54 having a pin connector 56,58. When connectors 40 and 42 are mated, an O-ring member 60 of male connector40 seats in a groove 62 of female connector42; the pin receptor48 mates with the pin connector 58, with an O-ring mem ber 45 included on the element 44 seating in a groove (not illustrated) in the semicircular member 54; and the pin receptor 50 mates with the pin connector 56; with an O-ring member47 included on the element46 seating in a groove (not illustrated) in the semicircular member 52.
When the conventional priorartconnector illus- trated in FIG.2 isto havefourconneotors,the semicircular members 52 and 54 include two rather than one pin connectors. Acorresponding increased number of protruding elements are also included. The physical configuration of the connectors 34, and particluarlythe semicircular members 52 and 54, limit the number of pin connectors that may be included in the male and female connectors 40 and 42, respectively.
Referring once again to FIG. 1,the air gun 12 includes a discharge region 64 having three ports disposedequallyabouttheairgun 12to produce a powerful acoustic wave coaxially about the air gun 12 which radiates radially outward from the air gun 12.
The underwater electrical connector34 is typically within three feet ofthe discharge region 64. The blast from the air gun upon discharge is equivalent of approximately 100 grams ofTNT.This blast force subjects the connector 34to a blast pressure of from approximately 4to 6 bars. Since the air gun is typically fired every 10 seconds for a period of days or sometimes weeks, the connector 34 is subjected not only to the saltwater environment and the hydrostatic pressure existing some 20 to 30 feet below the water line 20, but also to approximately 8,640 pressure impulses of some 4to 6 bars each per day.
The air gun is triggered by a 100 volt trigger pulse
o transmitted to the air gun from control circuitry
aboard the surveyvessel 10.Asensorin the air gun 12
produces a one volt feedback pulse approximately 15 to 20 milliseconds afterthe trigger pulse is received by the air gun. The peak of the feedback pulse occurs approximately one half millisecond after peak pressure is produced by the air gun. The feedback pulse is transmitted back to the processing circuitry on the survey vessel 10 where the feedback pulses from each air gun 12 are processed, and the respective trigger pulses advanced or delayed, so that the instant of generation of peak pressure for each oftheairgunsis within one millisecond, and ideally within one half millisecond of each other.
With continued reference to FIG. 1, electrical con nectorssimilartothe underwater electrical connector 34 may be included anywhere along the plurality of electrical cables 30, and may be included atthe location where each of the electrical cables 30 connect to the end bell termination 22.
Referring nowto FIGS. 3, 4, and 5, an underwater electrical cable 80 according to the present invention includes a first member 100 connected to the electical cable 32, and a second member200 connected to the electrical cable 34.
The first member 100 includes a first body member 102 molded onto the electrical cable 32 to fo rm a waterproof seal. Electrical pin connectors 104 and 106 are included in the first body member 102 and are suitably mounted in a conventional strain relief block 108. The pin connectors 104, 106 are electrically connected to electrical conductors 110 and 112 ofthe electrical cable 32 in a conventional manner.
Included in the first body member 102 are pin insulator receptors 114 and 116. The receptors 114, 116 are disposed coaxially about the pin connectors 104,106, respectively.
The second member 200 includes a second body member 202 which is suitably molded onto the electrical cable 34to form a waterproof seal. The second body member 202 includes two electrical pin receptors 204 and 206 which project outwardly from the second body member 202. Pin receptors 204,206 are mounted in a suitable manner in conventional strain relief block208, and are electrically connected in a conventional mannerto electrical conductors 210, 212 of the electrical cable 34.
Pin insulators 214,216 are included on the second body member 202 and are disposed coaxially about the pin receptors 204,206, respectively.
Members 100 and 200 are suitably dimensioned such that the electrical pin connectors 104,106 mate with the electrical pin receptors 204,206, and the pin insulators 214,216 matewith the pin insulator receptors 114,116, respectively.
In the illustrated embodiment, a plurality of 0-ring members 118 are disposed about the periphery ofthe pin insulator receptor 114 and about the periphery of the pin insulator receptor 116. In operation, when the body members 102 and 202 are mated with each other, the 0being members 118 included in the pin insulator receptors 114, 116 are compressed and seal about the periphery ofthe pin insulators 214,216, respectively, thereby forming a water-tight seal. The
O-ring members do not seat in a groove, but rather form a true wiping seal.
In an alternate embodiment, not illustrated, the
O-ring members 118 are disposed about the periphery
of each pin insulator214, 216. In either embodiment, one or more individual O-ring members may be used.
In the illustrated embodiment, a face O-ring member is included on the second body member 202. In operation, when the body members 102 and 202 are mated with each other, conventional locking rings 120 and 220 (FIGS. 4 and 5) are tightened, compressing the face O-ring member218againstthefirst body member 102, therebyforming a waterproof seal. In an alternate embodiment, not illustrated, the face O-ring member 218 is disposed on the first body member 102. Yetfurther, more than one face O-ring member may be used.
The illustrated embodiment includes two pin connectors 104,106 in thefirst body member 102, and two pin receptors 204,206 in the second body member 202. The configuration of the present invention, however, permits a vastly larger number, even 50 or more. Afar greater number of pin connectors can be included in the present cable connectorthan in the prior art cable connectors because of its configuration: the body member 102 contains only electrical pin connectors, and the body member 202 contains only electrical pin receptors.
The principles, preferred embodiments and modes of operation ofthe present invention have been described in the foregoing specification. The invention is notto be construed as limited to the particular forms disclosed, since these are regarded as illustrative ratherthan restrictive. Moreover, variations and changes maybe made bythose skilled in the art without departing from the spirit of the invention.
