Abstract (en)
[origin: WO2013180572A1] A drum unit (T) for an intervention string (0) for a well, comprising: - a drum (1) for said intervention string (0) with a drum axis (10> and with a radius (R), arranged in a structural frame (2) and rotatable by a motor (22); - a tension compensator (3) for said intervention string (0),- wherein said tension compensator (3) comprises a guide arch (31) displaceable in a direction generally along the intervention string (0), orthogonal to said drum axis (10), using a first force device (6, 6B, 62B) connected to said structural frame (2) for keeping said intervention string (0) in tension; - wherein at least a first end (31A) of said guide arch (31) is laterally displaceable in a direction generally orthogonal to said intervention string, parallel with said drum axis (10),- wherein said intervention string (0) runs between said guide arch (31) to or from said first end (31A) to said drum (1); - wherein said intervention string (0) runs via a second, opposite end (31B) of said guide arch (31) via a second, fixed guide (5) at said structural frame (1), directly or indirectly to or from said well.
