Abstract: Threaded connection for exploration and production of a hydrocarbon well, said threaded connection including a pin including an outer pin surface provided with an external thread, a box including 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 includes a releasable mounted first anti-rotation member which is arranged in a first radial recess provided in one of the outer pin surface and the inner box surface, and a second anti-rotation member provided at the other of the outer pin surface and the inner box surface.

Abstract: A threaded connection for hammering interconnected tubular members into a ground, such as onshore land or offshore seabed, for exploration and production of a hydrocarbon well, said threaded connection comprising a pin member comprising an external shoulder, a pin nose and a tapered pin threaded portion located between the external shoulder and the pin nose, and a box member comprising an internal shoulder, a box nose and a tapered box threaded portion located between the internal shoulder and the box nose.
