Subsea equipment alignment device

A system, comprising:

• a subsea equipment alignment device for coupling a first subsea tubular member to a second subsea tubular member, the subsea equipment alignment device comprising:
• an alignment sub adapted to be coupled to a stab, wherein the alignment sub comprises an orientation profile disposed on a surface of the alignment sub;
• and
• an alignment member having a profile designed to interface with the orientation profile of the alignment sub, and wherein the orientation profile and the profile are configured to couple upon a rotation of the alignment sub relative to the alignment member;
• wherein the subsea equipment alignment device comprises one or more fluid, electric, or fiber optic lines extending therethrough and one or more couplings disposed on at least one end thereof;
• wherein at least part of the subsea equipment alignment device is adapted to be connected to the stab and to be rotated up to at least 180 degrees relative to the stab while the stab is moved in a direction of a longitudinal axis of the stab.

An apparatus for coupling subsea tubular members, comprising:

• (a) an alignment sub adapted to be coupled to a stab, the alignment sub comprising:
• (i) a generally cylindrical body having one or more fluid, electric, or fiber optic lines extending therethrough, wherein the generally cylindrical body is adapted to be connected to the stab,
• (ii) one or more couplings coupled to at least one end of the alignment sub, and
• (iii) an orientation profile disposed on an inside surface of the alignment sub;
• and
• (b) a corresponding alignment member comprising:
• (i) a generally cylindrical body, and
• (ii) a profile designed to interface with the orientation profile of the alignment sub, the profile being disposed on an outside surface of the alignment member, and wherein the orientation profile and the profile are configured to couple upon a rotation of the alignment sub relative to the alignment member.
