Threaded connection for exploration and production of a hydrocarbon well

A method of making up a threaded connection for exploration and production of a hydrocarbon well, said method comprising:

• providing a threaded connection comprising:
• a pin comprising an outer pin surface provided with an external thread;
• a box comprising an inner box surface provided with an internal thread for mating with the external thread during rotational make-up of the threaded connection;
• and
• an anti-rotation device to allow relative rotation between the pin and the box in a make-up rotation direction and prevent relative rotation between the pin and the box in an opposite break-out rotation direction;
• wherein:
• the pin and the box extend along a longitudinal axis;
• the anti-rotation device comprises a first anti-rotation member which is arranged in a first radial recess provided in one of the outer pin surface of the pin and the inner box surface of the box, and a second anti-rotation member provided at the other of the outer pin surface of the pin and the inner box surface of the box;
• the first anti-rotation member comprises a first ratchet part provided with first ratchet teeth;
• the second anti-rotation member comprises a second ratchet part provided with second ratchet teeth which engage the first ratchet teeth of the first anti-rotation member at final make-up of the threaded connection;
• the first anti-rotation member comprises a spring part which allows radial movement of the first ratchet part in radial direction relative to the longitudinal axis when first ratchet teeth slide along second ratchet teeth during relative rotation between the pin and the box in the make-up rotation direction;
• and
• the first anti-rotation member is slidable relative to the first radial recess from a first tangential member position to a second tangential member position;
• a first recess contact surface of the pin and the box in which the first radial recess is provided defines a first recess boundary of the first radial recess;
• the first anti-rotation member comprises a first member contact surface facing the first recess contact surface;
• and
• in the first tangential member position, the first member contact surface of the first anti-rotation member is in contact with the first recess contact surface;
• and
• activating the anti-rotation device of the threaded connection by relative rotation between the pin and the box in the make-up rotation direction until final make-up of the threaded connection is reached.
