  • the present invention relates to the field of draw works.
  • the present invention relates to a system for recovering energy used for raising a load of a draw work.
  • the present invention relates to a draw work arrangement comprising such a system.
  • the present invention relates to a drilling rig.
  • the present invention relates to a method for recovering energy used for raising a load of a draw work.
  • draw works may be used for raising and lowering a load.
  • the draw work has to move the load up and down for raising and lowering or for compensating wave movements.
  • power may be transferred from a drive circuit into the load. If the load is lowered, power may be transferred back from the load into the drive circuit.
  • This power may be absorbed for example by braking resistors.
  • the braking resistors are adapted to burn off this power. As the system may reach a high temperature due to the burning off, cooling, for example with water, may be necessary. The power transferred back from the load is thus dissipated. There may be a need for recovering the power transferred back from the load into the system.
  • a system for recovering energy used for raising a load of a draw work comprises an energy transfer unit for supplying energy to a motor unit for raising the load of the draw work, wherein the energy transfer unit is connectable to the motor unit, and a storage unit, wherein the storage unit is connected to the energy transfer unit and wherein the storage unit is adapted for storing energy, which energy is released by the motor unit to the energy transfer unit, when the load is lowered.
  • This aspect of the invention is based on the idea that, instead of burning off the energy, which is transferred back to the system, the energy may be stored and reused.
  • Energy in this context may be any electric energy or power.
  • the term "energy transfer unit” may refer to a part of a system being responsible for transferring energy to one or more motor units.
  • the energy transfer unit may be coupled to any external energy source like a voltage source, current source, generator or the like.
  • the energy transfer unit may be adapted to operate in both directions, from the storage unit to the motor unit and from the motor unit to the storage unit.
  • the energy transfer unit may work as an electric motor drive unit and as an energy recover unit.
  • the term "motor unit” may refer to a part of a system, which is responsible for raising and lowering a load.
  • the motor unit may be used for raising and lowering the load due to a movement of a drill, for example, or due to compensation of wave movements.
  • the energy transfer unit may be coupled to one or more motor units, wherein each motor unit may be coupled to different parts of the system, for example to a load.
  • a motor unit may be any kind of engine, for example an AC or DC engine.
  • the motor unit When the load has to be raised, the motor unit may need a certain first amount of energy.
  • a certain second amount of energy may be released. This second amount of energy may be braking energy.
  • the motor unit may be adapted to transfer the released energy back to the energy transfer unit.
  • the energy transfer unit may then supply this energy to the storage unit, in which storage unit the released energy may be stored.
  • the storage unit may work as an electric motor drive unit and as an energy recover unit.
  • the storage unit and the energy transfer unit may be coupled for example via a controller area network (CAN) bus system, which may be commonly used.
  • CAN controller area network
  • the storage unit is adapted for supplying the stored energy back to the energy transfer unit for reusing the stored energy.
  • the stored energy may be transferred back to the energy transfer unit.
  • the energy transfer unit may need no further energy from an external energy source. If the stored energy is not sufficient for operating the motor unit, the energy transfer unit may further be adapted for receiving, in addition to the stored energy, energy from an external energy source.
  • the storage unit comprises a capacitor.
  • the storage unit may be a capacitor bank.
  • the capacitor may be charged in case of lowering the load and discharged in the next cycle, when the load is raised again.
  • cycle may refer for example to a repetitive movement of the draw work to compensate the wave movements.
  • One cycle may be for instance from one wave top to the next.
  • the storage unit comprises a battery.
  • the storage unit may comprise in addition to the capacitor a battery.
  • the battery may also replace the capacitor.
  • the battery may be any kind of common battery which is suitable for storing energy when energy is released in the system.
  • the system further comprises a resistor unit for absorbing excessive energy being released when the load is lowered.
  • the excessive power/energy may be absorbed or burned off in an additional resistor unit.
  • the resistor unit may also be connected to the energy transfer unit.
  • the storage unit is connected to a DC/DC converter of the energy transfer unit being adapted to work as a step up/step down converter.
  • the DC/DC converter may be adapted to operate bidirectional. To be able to process the increasing voltage within the capacitor, the DC/DC converter may be configured as a step up/step down converter.
  • the energy transfer unit is adapted for supplying energy supplied by the storage unit to further parts of the system for reusing the stored energy.
  • the energy transfer unit may supply also further parts of the overall system with the remaining energy.
  • a draw work arrangement comprising a load to be raised and lowered, a motor unit for raising the load, and a system having the above mentioned features.
  • draw work arrangement may refer to a primary hoisting machinery that is a component of a rotary drilling rig. Its main function may be to provide a means of raising and lowering traveling blocks.
  • the draw work arrangement is adapted for moving a drill, in particular a drill of a drilling rig.
  • the draw work may be part of a drilling rig or vessel with thruster or propulsion.
  • the draw work arrangement is adapted for moving a compensation weight, in particular for compensating wave movements of a drilling rig.
  • the load may be a compensation weight, which may be used in combination with thrusters or propulsions for compensating movements of drill ships or drilling rigs based on wave movements.
  • a drilling rig which comprises a draw work arrangement having the above mentioned features.
  • a method for recovering energy used for raising a load of a draw work comprising supplying energy to a motor unit by an energy transfer unit for raising the load of the draw work, wherein the energy transfer unit is connectable to the motor unit, lowering the load, and storing energy by a storage unit, wherein the storage unit is connected to the energy transfer unit, which energy is released by the motor unit to the energy transfer unit, when the load is lowered.
  • Figure 1 shows a system 110 for recovering energy according to an embodiment of the invention.
  • the system 110 may be part of an overall system 100, which may be for example a draw work arrangement.
  • the system 110 for recovering energy used for raising a load 150 of a draw work comprises an energy transfer unit 120 for supplying energy to a motor unit 140.
  • the motor unit may raise the load of the draw work.
  • the energy transfer unit is connectable to the motor unit.
  • the system 110 comprises therefore a storage unit 130.
  • the storage unit is connected to the energy transfer unit.
  • the storage unit is adapted for storing energy, which energy is released, when the load is lowered.
  • the load may refer to the electrical load of the draw work machine, which is dependent on the mechanical load of the system, for example used for hoisting a drill string.
  • the draw work may be used for moving a drill, for example of a drill ship.
  • the draw work may compensate this movement.
  • the energy recovery unit may be used in both cases. The benefit of using the energy recovery system may be biggest when the draw work has to compensate the wave movements.
  • the system 110 may also be seen as an electric drive with an energy recovery system, as both units, the energy transfer unit 120 and the storage unit 130, are electric motor drive and energy recovery units.
  • Figure 2 shows a system 120 for recovering energy according to a further embodiment of the invention usable in a draw work arrangement 200.
  • the system 120 comprises an energy transfer unit 120 and a storage unit 130.
  • the energy transfer unit comprises one or more parts 122, each of which consist of a DC/AC converter coupled to a switch.
  • the switch is coupled to a DC bus system 160.
  • the DC/AC converter is coupled to one or more motor units 140, which may be AC motors.
  • the storage unit 130 is also coupled to the DC bus system.
  • the storage unit comprises a capacitor 131 for storing energy, which is released, when a load coupled to one or more of the motor units is lowered.
  • the capacitor is coupled to the DC bus system via a DC/DC converter 121.
  • the draw work arrangement 200 may also comprise more than one storage unit.
  • the system comprises further a resistor unit 132, which may be part of the energy transfer unit or the storage unit or may be an individual part of the system.
  • the resistor unit may be used for burning off excessive energy, which may not be stored in the storage unit.
  • the resistor unit 132 is coupled to the DC bus system via a DC/DC converter 123 which is adapted to work as a switch, i.e. unidirectional.
  • An AFE unit 151 may be coupled to the DC bus system.
  • the AFE (active front end) inverter unit may be coupled to an external source 152. Via the AFE unit, excessive energy may be retransferred into further parts of the system.
  • the energy may be recovered, for example by using bidirectional rectifiers. This may be used in an equipment, where there is a cable connection to shore, for example a container crane. However, the isolated electrical system on board of a vessel may not be able to use this energy and the stability of the generators might be reduced.
  • a storage unit for example capacitors, may be used in combination with some power electronic to store the energy in one half cycle instead of being dissipated in a resistor and be brought back to the system in the next cycle.
  • the storage unit may be connected to the DC part of the inverter, at the same place as the braking resistors are connected in the conventional system of Figure 3 .
  • a more stable power consumption from generators may be achieved, which is desirable as a change in power is always a risk of trip of generators. Further, abrasion of the generators may be reduced.
  • the braking resistors of the conventional system are consuming big amount of cooling water due to the huge amount of heat to get rid of. This may be avoided with embodiments of the invention. Further, needed infrastructure, energy consumption and emissions may be reduced.
