Contraction joint for intelligent completion and downhole completion system

A contraction joint, comprising:

• an upper tubular member having a bore therethrough;
• a mandrel comprising:
• an upper mandrel sub comprising a port;
• a lower mandrel;
• and
• a mandrel crossover connecting the upper mandrel sub to the lower mandrel, wherein the mandrel is at least partially disposed within the upper tubular member,
• wherein the upper tubular member is capable of moving uphole and downhole to change a length of the contraction joint;
• a nipple housing connected to the upper tubular member;
• a piston housing connected to the nipple housing and the lower mandrel;
• a support piston disposed in the piston housing, the support piston being affixed to the upper mandrel sub of the mandrel via at least one piston retaining device,
• a lock housing disposed between the upper tubular member and the upper mandrel sub of the mandrel;
• and
• a stroke locking mechanism disposed within the lock housing, the stroke locking mechanism comprising a profile that engages the nipple housing,
• wherein, in a locked position, the stroke locking mechanism is supported by the support piston, and the profile of the stroke locking mechanism prevents the nipple housing from moving.
