The subsea production system includes a subsea wellhead and a safety shut-in system that has a valve assembly that is adapted to control flow and adapted to allow tools to be lowered therethrough on tubing. The subsea production system includes a cutting module that is adapted to be run into the passageway to allow tools to be lowered therethrough on tubing. The cutting module is further adapted to activate to shear the tubing that is lowered therethrough.
