Patent ID: 8459364

Claim:
A method for securely sluicing in a well tool in a well tubular, wherein the method comprises: arranging a landing sleeve provided with a barrier valve sealed and anchored against and within the well tubular downstream of a subsurface safety valve; displacing the well tool into the well tubular until a braking nose being connected to the well tool is placed in the landing sleeve; unlocking the barrier valve by means of a key being positioned on a leading end portion of the well tool wherein the key abuts one or more first locking dogs of a plurality of latches positioned in axial openings in an axially displaceable actuating sleeve, and the key axially displaces the latches and the actuating sleeve towards the barrier valve; axially displacing the leading end portion of the well tool past the first locking dogs by increasing the radial distance between two diametrically opposite first locking dogs such that the radial distance is larger than the diameter of the key by axially displacing the latches towards the barrier valve until the first locking dogs are displaced radially outwards into a first ring groove in the landing sleeve; and displacing the well tool upstream past the barrier valve.
