Apparatus and method for cutting tubular parts subsea

摘要

An apparatus for cutting a tubular part includes a carrying body configured to receive an end of the tubular part. In addition, the apparatus includes a cutting assembly disposed in the carrying body. The cutting assembly includes a continuous ring configured to be rotated relative to the carrying body. Further, the apparatus includes a first cutting element pivotally attached to the continuation ring. The first cutting element includes a cutting edge configured to engage and cut the tubular part. Still further, the apparatus includes a first actuator coupled to the first cutting element and configured to pivot the first cutting element between a retracted position and a cutting position. The apparatus also includes at least one sensor configured to measure a position of the first cutting element and a force applied to the first cutting element.

1. An apparatus for cutting a tubular part extending down into a sea or ocean bed, below the seabed, wherein the apparatus includes:
a carrying body configured to receive an end of the tubular part; a cutting assembly disposed in the carrying body, wherein said cutting assembly includes a continuous ring configured to be rotated relative to the carrying body; a first cutting element pivotally attached to the continuation ring at a first hinge joint, wherein the first cutting element includes a cutting edge configured to engage and cut the tubular part; a first actuator coupled to the first cutting element and configured to pivot the first cutting element about the first hinge joint between a retracted position and a cutting position towards the tubular part that is to be cut; and at least one sensor configured to measure a position of the first cutting element and a force applied to the first cutting element.
