ABSTRACT:
A device for intervention of a subsea oil and/or gas well by means of a tool (8) suspended by a cable (9), fed from or withdrawn to a vessel (1) and driven by a drive mechanism (12) located on the vessel. The device comprises a lubricator (5) having a tool housing for the insertion of the tool into the well, and a stuffing box (40) sealing around the cable after the tool is inserted into the well. According to the invention an injector which drives the cable in the well is located on the lubricator, and is controllable independently of the drive mechanism for the cable located on the vessel. The drive mechanism and the injector may be synchronized in a manner, among others, providing that the cable is hanging in a predetermined arc during the intervention, whereby the vessel may be moved from the well. Moreover, the invention relates to a method and a cable used together with the device.
