A tool can be used remove one or more outer layers of a tubular such as a flexible pipeline to enable an inspection on the remaining layers of the flexible pipeline. It allows the precise removal of outer layers of a flexible riser so that inspection can take place tubulars that otherwise could not be inspected with ultrasound.

A sacrificial breakaway mechanism comprising: a first piece attached to a fixed structure; a second piece; a plurality of connectors running between the second piece and the fixed structure; and a sacrificial element connecting the first piece to the second piece, wherein the sacrificial element is configured such that a tensile load exceeding a predetermined threshold exerted on the second piece causes the sacrificial element to break, separating the first piece from the second piece and allowing relative movement therebetween, the relative movement causing a sequential disconnection of the plurality of connectors.

An abrasive suspension eroding system has an eroding unit (11), which can be lowered into an existing drilled hole (1), in order to generate a high-pressure erosion jet for the abrasive suspension eroding of material (6, 20) in an existing drilled hole (1). The eroding unit (11) can be connected to a drilling fluid line (9) and is configured to generate a high-pressure erosion jet from a drilling fluid abrasive suspension device.
