Abstract

Concept of utilizing a locator with housing below the Mechanical Pipe Cutter (MPC) to land on a fishing neck for offshore applications and precisely locate the MPC in the cut zone and prevent sudden loading, shock and damage to the internal components of the MPC. This novel concept utilizes: 1. Bearing grade material to provide a low friction surface to interface with the top profile of the fishing neck. 2. Spring or shock absorber to dampen the sudden shock load experienced while landing and locating on the fishing neck on an offshore platform. 3. Another bearing grade material above the spring to provide a low friction surface. 4. A thrust, ball or roller bearing to prevent relative motion between the internal parts and MPC housing. 5. Lock nut to keep the spring and rest of the components seated and under compression. All of these parts are caged inside a housing that attaches below the MPC.
