Definitions

  • This present disclosure relates to systems and methods for optimizing the working environment in a drilling control room such as a drillers control room, crane cabin, or mud control room. More specifically, this disclosure may include systems and methods to selectively actively attenuate noise within a drilling control room. The disclosure may also include systems and methods to automatically adjust reflection and transmission of sunlight through the windows of the drilling control room as well as systems and methods to improve operator communication.
  • Drilling control room personnel must be adequately protected from a variety of environmental factors, including noise and sunlight.
  • Noise sources in a drilling control room may include the drawworks or other lifting system, top drive, HVAC system, and pipe handling equipment and pipes, as well as generators, centrifuges, pumps, fans, and other noise- generating equipment on or near the drill floor.
  • crane cabin operators must be adequately protected from noise sources such as the electric motor, hydraulic pump, and HVAC system. Because the noise level of equipment and other noise sources in proximity to the control room or cabin may exceed 100 dB(A), regulatory standards and/or design specifications for the project may require the noise level in the drilling control room to be limited.
  • Passive noise cancelling or suppression means such as noise insulating materials or panels, equipment blankets or shrouds, and vibration dampening structures may be used to reduce the noise level. While a combination of passive noise suppression means may be adequate to achieve a desired noise reduction, further reducing the noise level in the control room improves the quality of the working environment and allows the drilling rig to comply with stricter noise level standards. However, reducing noise (including vibration) to inaudible levels may not be desirable in some cases because certain noises can provide operators with additional feedback to determine whether an operation is being properly performed or equipment is properly functioning.
  • Sunlight may adversely affect the working environment in the drilling control room, particularly for operators who work in control rooms or cabins with large windows. Although the windows allow the operators to monitor and manage various activities, they also allow glare and heat into the control room or cabin. Controlling the amount and/or angle of sunlight that enters the control room or cabin without obstructing the operator's field of vision may provide increased comfort and safety for these operators. Furthermore, controlling the reflection or transmission of sunlight in the control room or cabin may improve energy efficiency by reducing the need or size of a dedicated HVAC unit.
  • HMI human-machine interface
  • a head -up display Projecting the information onto the windows or other surfaces in front of the operator, i.e. , a head -up display, may allow the operator to receive information without looking away from the monitored activities, thereby increasing safety for everyone involved in the operation.
  • a head-up display may also improve workplace ergonomics, as operators would not be required to repeatedly turn their heads to view the screens, and increased efficiency, as operators would not have to stop activities in order to review the information on the screens.
  • Voice feedback systems which speak certain information aloud instead of or in addition to displaying it on an operator's HMI screens, may allow operators to immediately identify alarms and other particular information and to differentiate between alarms, even when they are not looking at the screens. Such systems may increase safety, decrease response times, and reduce operator stress.
  • Communications with other operators, employees and contractors who are working at other locations on or near the drilling rig, and third parties located off-site may be difficult if operators cannot easily access telephones or public announcement/talkback systems from their control chairs or if the telephone or public announcement/talkback systems are not in their direct line of sight while monitoring on-going activities or HMI screens. Integrating telephone or public announcement/talkback systems, or both, into the existing computer and software systems for the operator control chairs or workstations may improve communication.
  • integrated telephone or public announcement/talkback systems may simplify the installation and commissioning of the drilling control room, crane cabin, or mud control room, reduce the number of interface points and networks required in the control room, improve the appearance of the control room, allow the telephone or public announcement/talkback systems to operate through the internet (VoIP), improve workplace ergonomics and comfort for the operators, and provide the option of recording voices during emergencies, incidents, or other selected circumstances.
  • VoIP internet
  • Embodiments of systems for optimizing the working environment in a drilling control room may include a subsystem for at least one of the following: selectively actively attenuating one or more noise sources affecting the noise level within the control room, controlling the reflection and transmission of sunlight through the windows of the control room, one or more head-up displays so that information that would otherwise be limited to display on the HMI screens is visible in the same line of sight as the machinery or activities the operator is required to observe, voice feedback systems to provide audible information to the operator, and telephone and/or public announcement/talkback systems to convey information to or from the operator.
  • the system may also include at least one microprocessor with associated software that is in electronic communication with the subsystem.
  • Embodiments of methods for optimizing the working environment in a drilling control room may include selectively changing an environmental condition of the drilling control room.
  • the environmental condition which may be in electronic communication with a microprocessor and associated software, may be a noise level within the control room, transmission and reflection of sunlight through the windows of the control room, a head-up display, audible information, or conveying information.
  • Embodiments of systems and methods to selectively actively attenuate one or more noise sources affecting the noise level within a drilling control room may make use of active noise cancelling or suppression technology arranged about the control room in combination with user-defined and source-specific noise attenuation modes.
  • Possible attenuation modes include:
  • the active noise cancelling technology may be of a kind known in the active noise control art that reduces or cancels the noise coming from a source by sending out sound waves with an inverted or anti-phase to that of the noise (see e.g., U.S. 6,343,127 Bl, which is incorporated by reference herein).
  • the original and inverted waves combine to form a new wave and effectively cancel each other out, an effect which is called destructive interference.
  • the described systems and methods may selectively attenuate the noise level of certain noise sources to a drilling control room while leaving other noise levels unchanged or at a different sound level.
  • Such systems and methods may permit an operator within the same control room to selectively reduce or increase a noise level suitable for her or his purpose relative to other operators without violating required maximum room or cabin sound levels, comply with working environment standards including but not limited to 65dBA, and lower the noise level inside the control room, thereby improving the working environment for the operators.
  • Embodiments of systems and methods to control the reflection and transmission of sunlight through the windows of the drilling control room may include a glass system with electronic or electrochromic tinted glass, or equivalent or similar technology, that may be used to adjust the reflection of sunlight based on the degree of sun exposure and/or the temperature of the working environment within the control room.
  • the electronic tinting or reflection of the glass may be manually adjusted.
  • the tinting or reflection may be automatically adjusted based upon information received by one or more light sensors and/or cameras, daytime light calculations related to the location of the control room on earth, self-learning computer modes based on input from the light sensors or cameras, or a combination thereof.

  • the various equipment and tools of the land rig 10 are monitored and controlled from a drilling control room 60, which is located on or near the drilling rig floor 70.
  • the environment might be offshore and the drilling control room may be located near a drill floor on a hull self-elevated by legs penetrating the sea base (jack -up environments) or on the hull of a drill ship (floaters environments).
  • the drilling control room is directly exposed to the exterior environment and thus operators working in the control room are directly exposed to noise from surrounding equipment and operations and to the sun's rays and heat.
  • the speakers 90 are in communication with a receiver 100 that receives an analog signal from a noise source "N" and passes the signal to a noise profile processing unit 110.
  • the noise profile processing unit 110 includes at least one microprocessor with associated software (or their equivalent) that implements one or more algorithms known in the art for analyzing incoming sound waves and generating remedial noise profiles.
  • the processing unit 110 passes the analog signal through an A/D converter and processes the digital signal to provide a remedial noise (attenuation) profile (see e.g. , U.S. 2005/0226434 Al, which is incorporated by reference herein).

  • the user control unit 130 may be located within the drilling control room 60 with the operator operating it while sitting in her or his control chair 210.
  • the user control unit 130 may provide different attenuation modes, which may include:
  • the ideal noise level profile also may be used to compare a noise source's current sound with that of the ideal sound.
  • the phrase "but not complete” means attenuation in a range of about 1% to about 99% of the noise source N unattenuated noise level, with the unattenuated noise level including any passive noise reduction methods currently employed with that noise source.
  • One or more accelerometers 134 may be placed outside of or within the drilling control room 60 to sense any vibrations running through the room's framing structure. One or more accelerometers 134 may also be placed directly on the noise source N.

  • the electronic control of the tinting or reflection of the windows 140 allows the reflection and transmission of the incoming sunlight to be adjusted, which may reduce heat and sun-glare inside the drilling control room 60.
  • Such control of tinting or reflection may reduce strain on the HVAC system for the control room 60, enabling it to work more efficiently and reducing energy costs, or allow the size and/or weight of the HVAC system to be reduced.
