A drum unit for an intervention string for a well includes a drum with a drum axis and with a radius, arranged in a structural frame and rotatable by a motor and a tension compensator. The tension compensator includes a guide arch displaceable in a direction generally along the intervention string, orthogonal to the drum axis, using a first force device connected to the structural frame for keeping the intervention string in tension. At least a first end of the guide arch is laterally displaceable in a direction generally orthogonal to the intervention string, parallel with the drum axis. The intervention string runs between the guide arch to or from the first end to the drum. The intervention string runs via a second, opposite end of the guide arch via a second, fixed guide at the structural frame, directly or indirectly to or from the well.

Drum unit with an arch compensator for a well intervention string

A drum unit for an intervention string for a well includes a drum with a radius for the intervention string, arranged in a structural frame and rotatable by a motor, the drum being arranged translating along a drum axis and driven by a translation motor, for controlled winding of the intervention string onto the drum relative to a first, fixed guide in the structural frame. A compensator includes a guide arch, the guide arch being displaceable in a direction orthogonal to the drum axis using a force device at the structural frame. The intervention string runs between the guide arch and the first fixed guide to or from a first end of the guide arch to the drum. The intervention string runs via a second, opposite end of the guide arch via a second, fixed guide at the structural frame, to or from the well.
