Abstract: Systems, apparatuses, and methods are described for a smart energy home. The smart energy home may promote optimization of consumption of electricity by appliances and other consumer devices. Prioritization of where and when electricity may be provided to various appliances, chargers, or other devices which draw electrical power may be managed by the smart energy home. Information concerning prevailing weather conditions and contemporaneous electrical tariffs may be utilized in processes executed by the smart energy home. Related systems, apparatuses, and methods are also described.

Abstract: Systems, apparatuses, and methods are described for a backup system. The configuration of the backup system in terms of number of load groups, power sources, and/or total power limit may be altered. An interface enclosure of the backup system may include a housing for electric circuitry, where the housing may be a clam-shell design including a base plate and a backup interface module. The base plate may comprise a frame, one or more detachable hinges, and/or two or more multi-terminals. The base plate may include a plurality of multi-terminals. The multi-terminals may be arranged to connect to one or more load groups, power sources, power devices, other multi-terminals, etc. Each load group that is connected to the multi-terminals may be disconnected from the utility grid and connected to the one or more sources of backup power in the case of a utility grid shutdown.

Abstract: A method for drilling a wellbore, wherein use is made of a top drive device including: multiple electric top drive motors each having a rotor, a transmission to which the rotors of the multiple top drive motors are operatively connected, a rotary stem or quill operatively connected to the transmission allowing the rotary stem or quill to be driven by the top drive motors in order to impart rotary torque to a drilling tubulars string connected to the rotary stem or quill of the top drive device, wherein at least one, preferably each, of the top drive motors has an operable clutch device configured to selectively connect and disconnect upon command the rotor relative to the transmission. The method includes providing a command to the one or more top drive motors having a clutch so as to selectively connect and disconnect the rotor thereof relative to the transmission by operating the clutch.

Abstract: A method for servicing a top drive device of a wellbore drilling installation. The installation comprises a drilling tower, a drill floor having a well center through which a drilling tubulars string can pass along a firing line. A trolley is guided along a vertical trolley rail. A top drive device is attached to the trolley and comprises one or more top drive. A motion arm assembly comprises a base and an extensible and retractable motion arm, wherein the base is guided by a vertical motion arm rail. The motion arm has an operative reach that encompasses the firing line. The motion arm assembly is adapted to support at least one of a well center tool, e.g. an iron roughneck tool and a tubular gripper member, and allowing to bring said well center tool or tubular gripper member in the firing line.

Abstract: A method for removal of a top drive device in a wellbore drilling installation, for servicing and/or exchanging a top drive device. The frame of the trolley and the top drive device are provided with cooperating vertical guide members so that the top drive device is vertically displaceable and guided relative to the frame. The top drive device has an operative position above the rotatable head clamp assembly carrier, which is releasably connected to first and second vertical frame members. In order to service and/or exchange of the top drive device, the method includes releasing the rotatable head clamp assembly carrier from the first and second frame members, removing the rotatable head clamp assembly carrier, lowering the top drive device relative to the frame of the trolley until the cooperating vertical guide members thereof disengage, moving the lowered and disengaged top drive device to a service and/or storage location remote from the firing line.

Abstract: The present invention relates to a top drive well drilling installation comprising a trolley guided along one or more vertical rails along the drilling tower, which trolley is provided with a support frame supporting the top drive unit and a rotating head-clamp. The rotating headclamp comprises an open-centered rotary body defining a pipe passage; a thrust bearing supporting the rotary body; and multiple mobile pipe retainers supported by the rotary body providing an operative and a non-operative position allowing passage of a pipe and engagement below a shoulder of a pipe of the drill string so as to suspend said drill string therefrom. At least the tubular stem is vertically movable relative to the rotating headclamp between an upper remote position allowing the engagement of a pipe of the drill string by the rotating headclamp and a lower connection position allowing the attachment of the tubular stem with the pipe.

Abstract: A process is described for cleansing and deodorizing an environmental space including deodorizing a space with an ozone treatment for a pre-selected time; and thereafter, automatically and without human intervention, exposing the space to a nebulized liquid, having ozone quenching properties and comprising an odor neutralizing or air freshening agent, to reduce ozone levels to a level safe for human exposure and to remove residual odors. An apparatus for carrying out the process and compositions for use in the process are further disclosed.
