Abstract: A control line protector for protecting one or more downhole control lines running alongside a pipe, comprising a body with one or more channels, wherein each of the one or more channels is adapted to receive a control line, and an attachment assembly coupled to the body for attachment to an outer surface of the pipe, wherein the attachment assembly comprises an inner collar comprising a tubular portion and a plurality of gripping arms extending axially away from the tubular portion and arranged to deflect radially inwards and an outer sleeve adapted to slide at least partially over the inner collar, wherein when the inner collar and the outer sleeve are arranged axially around the pipe and pressed together each of the plurality of gripping arms is deflected radially inwards by the outer sleeve to grip the pipe and thereby secure the body to the outer surface of the pipe.

Abstract: An aerodrome maintenance apparatus for monitoring runway and taxiway conditions and remotely reporting the status of the runway or taxiway. The apparatus comprises: a drive unit arranged to mount one or more rails to provide movement of the apparatus along the one or more rails; a detection unit comprising one or more sensors configured to detect one or more parameters of the runway or taxiway; and a communications unit arranged to transfer data derived from the detection unit from the apparatus to a remote server. The apparatus is arranged to advance along the one or more rails and transfer data representative of one or more parameters of the surface to a remote server.

Abstract: A control line clamp includes a clamping element for retaining one or more control lines alongside a pipe; a first collar; and a second collar. The clamping element is arranged to be attached to the pipe by positioning the first and second collars around the pipe on opposing sides of the clamping element and moving the first and second collars relatively towards each other in an axial direction.

Abstract: A control line protector for protecting one or more downhole control lines running alongside a pipe, comprising a body with one or more channels, wherein each of the one or more channels is adapted to receive a control line, and an attachment assembly coupled to the body for attachment to an outer surface of the pipe, wherein the attachment assembly comprises an inner collar comprising a tubular portion and a plurality of gripping arms extending axially away from the tubular portion and arranged to deflect radially inwards and an outer sleeve adapted to slide at least partially over the inner collar, wherein when the inner collar and the outer sleeve are arranged axially around the pipe and pressed together each of the plurality of gripping arms is deflected radially inwards by the outer sleeve to grip the pipe and thereby secure the body to the outer surface of the pipe.

Abstract: An aerodrome maintenance apparatus for monitoring runway and taxiway conditions and remotely reporting the status of the runway or taxiway. The apparatus comprises a drive unit operable to provide self-controlled rolling movement of the apparatus along a surface of a runway or taxiway of the aerodrome, a detection unit comprising one or more sensors configured to detect one or more parameters of the surface, and a communications unit comprising a transceiver arranged to transfer data derived from the detection unit from the apparatus to a remote server. The apparatus is arranged, in use, to move along the surface and transfer data representative of one or more parameters of the surface to a remote server.

Abstract: A float equipment attachment assembly includes a float equipment for mounting to a tubing string. The float equipment includes a tubular body and a plurality of gripping arms extending longitudinally away from the tubular body arranged to deflect radially inwards. An attachment sleeve has an inner diameter tapered to form a conical abutment portion. The attachment sleeve and float equipment are arranged axially around the tubing string and are pressed together. The gripping arms are deflected radially inward by the conical abutment portion to grip the tubing string to mount the float equipment to the tubing string.

Abstract: A method of connecting an end part of a pipe attachment device to a part of a function element, includes: aligning longitudinal axes of a substantially tubular end part of a pipe attachment device and a substantially tubular part of a function element; applying a force that moves the end part of the pipe attachment device relatively towards the part of the function element along the longitudinal axis. Contact between the end part of the pipe attachment device and the part of the function element causes each of a plurality of fingers on the end part to elastically deflect. Applying the force so that each of the plurality of fingers on the end part returns from their deflected position and is retained in one or more holes in the part of the function element.

Abstract: An attachment device for an element is made to be arranged on a downhole tubular body, in which an end portion of a sleeve, which is arranged to surround a portion of the tubular body, comprises an attachment portion. The attachment portion comprises at least one clamping element arranged for axial displacement by the abutment of an abutment surface against a conical abutment portion of a surrounding adapter sleeve.
