Abstract
An apparatus includes a first member, a second member releasably attached to the first member, and a control line shear mechanism disposed proximate an interface between the first member and the second member. The first and second members can each have a longitudinal bore therethrough and can be moveable in an axial direction to release from one another. The control line shear mechanism may comprise a first shear member attached to the first number and a second shear member attached to the second member, wherein the first and second shear members are adapted to cooperatively shear a control line as the first and second members separate. A method includes separating a first member from a second member and, before or during the separating step, cutting a control line proximal to the paint of separation of the first and second members.
