Abstract

The invention concerns a compensating cylinder 100 unit suitable for compensating relative movements between a stationary frame 40 and a compensated frame 50 constituting parts of a coiled tubing compensation system 30, where the compensated frame 50 is connected to the compensating cylinder 1. All the necessary tools for the coiled tubing system may be arranged on the compensated platform in order to ensure compensation of vertical movements during operation. The cylinder unit 100 comprises a compensating cylinder 1 suitable for connection to the compensated frame 50 and a fluid reservoir 5 suitable for connection to the stationary frame, wherein the compensating cylinder 1 is in fluid communication with the fluid reservoir 5 to allow for an axial displacement of the compensating cylinder 1 relative to the fluid reservoir 5. Furthermore, the compensating cylinder 1 is partly enclosing the fluid reservoir. The invention also concerns a method for altering a compensating cylinder unit from an operational configuration to a transport configuration.
