Description

- The field of this invention of that of umbilical reels which store and handle hose and/or electric and/or fiber optic control lines for deepwater offshore service. These reels typically pay out these lines, called umbilicals, and mechanics clamp the umbilical to a drilling riser or other pipe string being run to the seafloor. The actual weight of the umbilical is typically supported once it leaves the reel and in the water by the riser or pipe to which it is clamped. Typically these reel units have to be closely monitored to insure that excessive tension which can destroy the umbilical is not encountered as it is being deployed or in the event of unexpected movement of the riser or pipe to which it is clamped.
- When the drilling riser or other pipe string is lowered, an operator will rotate the spool to allow umbilical to be paid off in accordance with the downward movement of the riser or pipe. In some cases, the motor can be left in the take up mode, and the umbilical simply be pulled off the spool against a relatively constant torque provided by the motor power.
- As offshore services are required in deeper water the length of umbilical deployed from the reels increases and this causes the diameter differential between a fully loaded spool and a fully deployed spool to increase thus multiplying the maximum tension on the umbilical during deployment. A fixed preset torque on the motor which provides a tension of 1,000 pounds on the umbilical when the spool is fully loaded can vary to over 3,000 pounds when the spool is nearly empty.
- This variation in tension from the motor which has a constant supply pressure can be offset by the operator changing the setting on the air pressure regulator as it seems reasonable to do so. As there are a number of factors involved in this judgment, it is imprecise at best. Some of these factors are the level which the umbilical is being paid off, unit weight of the umbilical, how well the reel is greased, and the angle to the sheave which the cable is going over.
- The object of this invention is to provide a method for automatically controlling the motor torque on an offshore reel to provide a constant tension on an umbilical as it is being deployed from a maximum radius on a full spool to a minimum radius on an empty spool.
- A second object of the present invention is to provide a method of counting the revolutions of the spool during the umbilical deployment, determining the current radius to the cable being deployed, and automatically controlling the motor torque in a fashion to maintain a constant tension limit on the umbilical.
- A third object of the present invention is to provide means to calibrate to motor torque in actual field conditions.

FIG. 1 shows avessel 1 floating on the ocean 3 and having adrilling riser 5 extending down toward ablowout preventer stack 7. Theblowout preventer stack 7 is landed on asubsea wellhead 9 which is in turn landed on theseafloor 10.Casing 12 extends into the seafloor below thesubsea wellhead 9 for the purpose of drilling an oil or gas well. -
Reel 14 is positioned on thedeck 16 ofvessel 1 with umbilical 18 extending over pulley orsheave 20 and going down the side of theriser 5. Riser 5 is a series of jointed pipes and as they are sequentially connected and lowered into the ocean to lower theblowout preventer stack 7,clamps 22 secure the umbilical 18 to thedrilling riser 5. Theriser 5 andblowout preventer stack 7 may weigh as much as 650,000 lbs. When lowered with the umbilical 18 attached, if the rotation of thereel 14 is stopped, the full 650,000 lb. load can be put on the umbilical, destroying it. An even worse consequence is that the pulley orsheave 20 can be pulled down from its mounting and injure personnel on the deck. - Referring now to
FIG. 2 ,reel 14 is shown with aframe 30 and aspool 32.Main disk 34 is shown mounted to thespool 32 by fourslip clutch assemblies 36. As will be seen later, theslip clutch assemblies 36 provide a preset friction grip on themain disk 34 to withstand torque as thespool 32 rotates, but will be allowed to slip if the preset friction grip is exceeded when a large tension on the umbilical 18 is encountered. Aslip torque controller 37 is located on the side of thespool 32 which automatically adjusts the control pressure to theslip clutch assemblies 36 as thespool 32 rotates allowing the friction grip on themain disk 34 to vary to maintain a relatively constant slip tension on the umbilical 18 as successive layers of umbilical 18 leave thereel 14 at different distances from thespool 32 centerline. - Motor 38 is shown with gear 40 (shown through the motor for clarity) engaging the
outer gear profile 42 on the perimeter ofmain disk 34.Gear 40 and theouter gear profile 42 are positively engaged such that if themotor 38 does not turn, themain disk 34 cannot rotate. Alternately, the connection between the motor and the main disk can be by roller chain and sprocket profiles, as is well understood in the industry. Amotor torque controller 43 is located next to themotor 38 which adjusts the air pressure to themotor 38 as thespool 32 rotates to maintain a relatively constant tension on the umbilical 18 as the umbilical 18 leaves thereel 14. -
Brake assemblies main disk 34 will not rotate about the centerline ofspool 32. - Spool 32 rotates on
main bearings 48.Panels FIG. 3 , hasgear 58 to receive motive power from themain disk 34 and a manual clutch and handle 59 which allows for adjustment of the wrapping position of the umbilical. - Locking
pin 60 is engaged inlocking pin socket 61 which is fixed toleg 62 of thereel frame 30. Locking pockets 63 are provided on the side ofspool 32 for engaginglocking pin 60 to positively stop the rotation of thespool 32. When lockingpin 60 is an instrumented load pin, it can be engaged and give a positive reading of the torque output of the motor. - Locking
pin 65 is engaged inlocking pin socket 66 which is fixed to themotor mount 67 on theframe 30. One ormore holes 68 are drilled through themain disk 34. When lockingpin 65 is engaged in ahole 68, themain disk 34 will not rotate. When lockingpin 65 is an instrumented load pin, it can be engaged to give a positive reading of the slipping force when the umbilical 18 is pulled, as long as thebrakes motor 38 is allowed to free wheel. - Referring now to
FIG. 3 ,levelwind 56 is shown having on a pair ofdiamond pattern screws Level wind carriage 74 containsrollers 76 for controlling the position of the umbilical 18 (not shown) when it is being reeled in. Spool 32 hasside flanges - Referring now to
FIG. 4 , aslip clutch assembly 36 is shown withbrake pads main disk 34. Piston 84 cooperates withconical springs 85 to manually preload thebrake pad 80 onto themain disk 34.Main disk 34 is pushed againstbrake pad 82 and imparts the same load tobrake pad 82.Cylinder head 86 seals thecylinder 87 allowing thepiston 84 to be operated. - Pressure in
pressure port 88 controls the air pressure in thechamber 89 which acts against the conical springs 85 to reduce the friction load on thebrake pads main disk 34 to be reduced when a lower slipping load is desired. - Pressure in
pressure port 90 controls the air pressure inchamber 91 to increase the friction load ofbrake pad 80 ontomain disk 34 and therefore ofmain disk 34 onto brake pad 81. This allows the friction grip on themain disk 34 to be increased when a higher slipping load is desired. -
Bolts 92 attachbracket 93 tobracket 94 in a portion in front of and behind the cylinder 87 (not shown).Slots 95 allow for position adjustment ofbracket 93 relative tobracket 94 in a first direction.Bolts 96bolt bracket 94 to theside flange 78 of the spool.Slot 98 allows for adjustment of the slipclutch assembly 36 along the surface of theside flange 78 of the spool generally in adirection 90 degrees to the adjustment allowed byslots 95. - Referring now to
FIG. 5 , is a section of a slipclutch assembly 36 with a schematic of thetorque controller 37 system which contains arevolution counter 100, acomputer 102, apressure transducer 104,electric lines 105, twopressure increase valves vent valve 110, and an emergency shut downbutton 112. Therevolution counter 100 can count thespool 32 revolutions by sensing a passing object, sensing gravity or other means. Anair storage tank 113 and connectingair lines 114 will be pressurized prior to operations. - With specific input information on the diameter of
spool 32, the width ofspool 32 and the diameter of umbilical 18, the row number of the current umbilical being paid off, the number of umbilical wraps on that row, and the desired tension, thecomputer 102 can calculate the pressure forport 90 required to generate the desired torque. Thecomputer 102 will read the current pressure as indicated on thepressure transducer 104 and compare it to the desired pressure. - The
computer 102 will then either send an electronic signal to open thevent valve 110 to reduce the pressure inport 90 orpressure increase valve 106 to increase the pressure to match the desire. Alternately, a pressure regulator as is well understood in the industry may be controlled to maintain the desired pressure inport 90 to produce the required torque on thespool 32 to keep the umbilical 18 tension stable. - If an emergency occurs and emergency shut down
button 112 is pushed, it will lockbrake pads main disk 34 by putting pressure intoport 88 on therefore on the opposite side of thepiston 84. This will have the air pressure loading adding to theconical spring 85 loading for an increased friction loading on themain disk 34. - Referring now to
FIG. 6 , a section through the reel is generally taken as indicated by section “6-6” onFIG. 2 . The slip clutch assemblies are indicated as being mounted at aradius 120 from the centerline of the reel. The umbilical 18 is shown to be paid off at aradius 116 on a full reel and at aradius 118 on a near empty reel. Thespool 32 is shown to be 21 umbilical wraps wide. The objective is to control the friction grip on themain disk 34 at theradius 120 such that the slip tension on the umbilical 18 will be the same at the full reel radius of 116 or the empty reel radius of 118. As the radii are different in these situations, the problem is most easily understood in terms of torques about the rotational centerline of the spool. - As a real life example, the problem will be demonstrated in terms of a desired umbilical tension of 1000 lbs., an
outer radius 116 of 45 inches, andinner radius 118 of 15 inches, a slipclutch assembly radius 120 of 30 inches, area ofpiston 84 energized by air is 1.5 sq. in. rig air supply will be at least 120 p.s.i., and a sliding coefficient of friction of 0.3. - The torque generated by the umbilical on the full reel is 45 inches times 1,000 lbs. or 45,000 in-lbs. The total resisting force on the slip assemblies will be determined by 45,000 in-lbs./30 inches or 1,500 lbs. Sliding friction is calculated by the normal force (perpendicular to the surface) time the coefficient of friction. This means that the total normal force will need to be 1,500 lbs./0.3=5,000 lbs. The normal force is divided up between four slip clutch assemblies with friction on two sides each, so the individual required normal force is 5,000 lbs./8=625 lbs. This means that the conical springs 85 as seen on
FIG. 4 need to be designed to output 625 lbs. in each of theslip assemblies 36. - The torque generated by the umbilical on a nearly empty reel is 15 inches times 1,000 lbs. or 15,000 in-lbs. The total resisting force on the slip assemblies will be determined by 15,000 in-lbs./30 inches or 500 lbs. This means that the total normal force will need to be 500 lbs./0.3=1,666 lbs. So the individual required normal force is 1,666 lbs./8=208 lbs. As the conical springs 85 as seen on
FIG. 4 are designed to output 625 lbs. in each of theslip assemblies 36, 625-208 or 417 lbs. need to be relieved from theslip assemblies 36. As the piston area is 4.00 sq. in and the rig air supply is 120 p.s.i., 4.00 sq. in.times 120 p.s.i.=480 lbs. is available and so is sufficient. The computer will calculate 417 lbs./4.00 sq. in.=104.25 p.s.i. as required and directpressure increase valve 106 to increase to that pressure or ventvalve 110 to vent until the pressure is reduced to that level. - The reel is shown with 9 wraps presently on the outer layer. It will start with zero pressure in
port port 88 slightly to compensate for the slight smaller radius on the second layer of umbilical wraps. Twenty one wraps later, it will adjust again as it goes to the next layer. - A similar process happens on the
motor torque controller 43, except that it must sense the rotation of thespool 32 from its stationary position on the frame. Based on its determination of the current level of the umbilical on thespool 32, it will adjust the pressure supplied to the motor to give a constant tension on the cable at a lower value than the slip tension, i.e. 750 lbs. - In this way the slip tension and motor tension can be at a desired constant value which are relatively close to one another for maximum equipment and personnel safety.
- Referring now to
FIG. 7 ,motor torque controller 43 is shown withcomputer 130,revolution counter 132,pressure increasing valve 134,pressure reducing valve 136 andpressure transmitter 138. Air is supplied tomotor torque controller 43 throughline 140 and anoutput signal 142 is sent to thedome regulator 144 to control the pressure sent to themain control valve 146 which in turn sends the signals tomotor 38.Manual valve 148 is used to shift the main control valve to change the direction of the motor. - The particular embodiments disclosed above are illustrative only, as the invention may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein.
