Abstract: A compensating cylinder unit for compensating relative movements between a stationary frame and a compensated frame which includes parts of a coiled tubing compensation system. The compensating cylinder unit includes a fluid reservoir configured to connect to the stationary frame, and a compensating cylinder configured to connect to the compensated frame, to at least partly enclose the fluid reservoir, and to be in a fluid communication with the fluid reservoir to allow for an axial displacement of the compensating cylinder relative to the fluid reservoir.

Abstract: A replaceable antenna assembly for use with a piston accumulator configured for supplying fluid to a hydraulic cylinder is provided. The antenna assembly includes a hollow manifold for flow of fluid and an antenna connected into or onto the manifold for emitting and receiving electromagnetic waves. The hollow manifold is connectable to and configured to be in fluid communication with both the piston accumulator at one end and a pressure line at the other end. The pressure line is connectable to an external high pressure gas bank. The antenna assembly further includes at least one first bore for transferring signals to and from the antenna and at least two fluid channels symmetrically displaced around the circumference of the antenna, thereby ensuring that most of, or all, fluid flows on the radial outside of the antenna during use.

Abstract: A column machine that stands on a deck. The deck includes a rack, a protective cover associated with the rack, and a first and a second rail. The column machine includes a moveable upper device, a drive wheel, an upper carriage connected to the upper device, a lower carriage comprising a first track, a second track, and a protection holder, and a column arranged between the upper carriage and the lower carriage. The drive wheel is arranged in a vertical plane of the column machine and extends parallel relative to a longitudinal direction of the first and second rails. The drive wheel moves along the rack. The first track and the second track cooperate with the first and second rails. The protection holder uncovers the rack in a first area close to the drive wheel so that the remaining areas of the rack remain covered by the protective cover.
