A sensor transportation apparatus comprises at least one engagement structure to connect the sensor transportation apparatus to the sensor assembly, a pair of wheels arranged to rotate about an axis of rotation substantially perpendicular to a longitudinal axis of the sensor assembly when the transportation apparatus is connected to the sensor assembly, and an orientation structure comprising the pair of wheels and an orientation projection extending between the pair of wheels. Lateral extremities of the pair of wheels and the orientation projection together define a curve extending circumferentially around a portion of the circumference of the elongate sensor assembly. A rotational centre of the curve is offset from a central axis of the elongate sensor assembly and a rotational axis of the pair of wheels is above the central axis of the elongate sensor assembly when the sensor transportation apparatus is substantially horizontal.

A device for injecting a fluid into a mechanical system that may undergo heating, comprising at least one body containing a thermally triggered charge generating combustion gas, ignition of the charge being able to be triggered under the action of an ignition command and/or under the effect of a heat contribution, from a heating area of the body toward the charge, a reservoir containing the fluid, means for fastening the device to the mechanical system, the fastening means adapted to put the reservoir in fluid communication with the mechanical system, and means for delivering pressurized fluid outside the reservoir through the action, directly or through intermediate means, of the combustion gases. Within the device, the fastening means comprise at least one injection sleeve provided with an outer thread coated with an anti-loosening adhesive film. The invention also relates to a mechanical system equipped with at least one such device.

The invention provides an autonomous subsea barrier fluid system for a subsea pressure booster, the subsea pressure booster comprising a process fluid compartment, a motor compartment and a rotor assembly extending from the motor compartment into the process fluid compartment with one or several shaft seals separating the process fluid from the barrier fluid in the motor compartment. The subsea barrier fluid system is distinguished in that it comprises: a subsea barrier fluid pump, a barrier fluid delivery line, arranged between the barrier fluid pump and the motor compartment, a pressure controlled regulator, operatively arranged to at least one of the barrier fluid delivery line and the subsea barrier fluid pump, a subsea barrier fluid storage, and a barrier fluid suction line arranged from the subsea barrier fluid storage to the subsea barrier fluid pump.

The present disclosure is directed to an improved metalworking lubricant monitoring, logging, recording, calculating, analyzing, alerting and reporting apparatus, system and method that monitors data and changes to the lubricant application process and the amount and concentration of lubricant being dispensed or delivered, analyzes, calculates and records data and changes or alterations to the amount dispensed, and alerts or reports the data and changes in real-time, when necessary, over various communication channels, to those responsible for overseeing the system changes.

A device for stabilizing pressure inside a gear's housing or a wheel's hub includes a bladder, and a conduit coupled to the bladder and coupleable to a volume containing a lubricant. The bladder includes a chamber having a volume, and is configured such that the chamber's volume increases as a fluid enters the chamber, and decreases as fluid leaves the chamber. The conduit includes a first end positionable adjacent the lubricant containing volume, a second end coupled with the bladder, and a passage between the first and second ends, and is configured to hold fluid disposed in the passage and direct the fluid between the first and second ends. When the conduit is coupled to the lubricant containing volume, the volume of the bladder's chamber, the passage of the conduit and the lubricant containing volume are isolated from the ambient environment.

The disclosure relates to a carriage apparatus for carrying a tool string down a wellbore in a wireline logging, and an orientation apparatus and hole finder device for a wireline logging tool string. In some embodiments the carriage includes a protection structure which extends longitudinally around a wheel of the apparatus to thereby prevent a side of the wheel from contacting a wall of the wellbore. In some embodiments an orientation apparatus and hole finder are arranged so that the orientation apparatus orientates the hole finder device in the wellbore so that a tip of a nose section of the hole finder is elevated above a low side of the wellbore by a height and offset from and above a longitudinal axis of the tool string.
