The invention relates to a force generator for generating a linear pressure force, including a housing, an output wedge displaceably arranged in the housing, and a drive wedge for transmitting an externally exerted pressing force into a linear movement of the output wedge. The output wedge is connected to a first pressure element. The housing is connected to a second pressure element. A force applied to the drive wedge causes displacement of the first pressure element relative to the second pressure element. The force generator solves the technical problem of providing a high pressure force and using the known press jaws for this purpose.

A mobile cutting tool is for cutting a subsea tubular structure and has i) a tool body for receiving the subsea tubular structure in an enclosure thereof; ii) an actuator mounted on the tool body at one side of the enclosure; iii) a non-rotatable cutting element provided on the actuator, the actuator with the cutting element for carrying out a translational cutting movement through the enclosure including the subsea tubular structure, and iv) a reaction member mounted at an opposite side of the enclosure of the tool body opposite to the cutting element for applying a reaction force on the subsea tubular structure during cutting. A method is for cutting a subsea tubular structure, wherein a non-rotating translation cutting movement is used for cutting.

Cutting tools for pipe cutting frames are disclosed. Example split frame pipe cutting tools include a frame and a slide tool configured to position a cutting edge in contact with the workpiece to performing cutting or boring on the workpiece, the slide tool comprising: a radial advancement mechanism configured to provide radial advancement of the cutting edge based on circumferential advancement of the slide tool by the frame; and an axial guide rail; a recirculating bearing carriage configured to slide in an axial direction along the axial guide rail and to couple the cutting edge to the axial guide rail; an axial advancement mechanism configured to advance the cutting edge in the axial direction with respect to the workpiece by translating radial advancement by the radial advancement mechanism to axial advancement based on a cutting template coupled to the radial advancement mechanism.

A powered cutting tool for cutting tubular or cylindrical workpieces such as pipe is described. The cutting tool includes a base, an electric motor, a collection of rollers, a frame, a feedscrew, an auto cut wheel system, and a handle for rotating the feedscrew and adjusting the position of the auto cut wheel system relative to the rollers. In certain versions, the cutting tool includes torque-limiting provisions, to limit the amount of torque applied to the feedscrew. In certain versions, the cutting tool includes rollers and press wheels featuring non-metal outer surfaces.

An articulation joint manufacturing process comprises cutting an elongated tube to form a multiplicity of links wherein adjacent links are connected by a bridge. The method comprises forming a fracturable portion on each bridge and connecting a multiplicity of springs to adjacentts links to form a workpiece. The method further comprises applying a torsional force to the workpiece about its longitudinal axis to fracture each bridge to form an articulation joint comprising a series of links wherein adjacent links are connected by at least one spring. Certain steps are formed by a laser. In one method, the springs are positioned on a mandrel and the springs are welded to the workpiece. The fracturable portion on the bridges may be produced by forming an indentation which may be a score, a perforation, an elongated indentation or an oval shaped indentation.

An underwater tool (5; 205; 305) including a grabber arrangement (15; 215; 315) and a cutter arrangement (20; 220; 320) connected together. The grabber arrangement comprises a plurality of grabber elements (30; 230; 330) disposed on first and second sides (35a; 235a; 335a; 35b; 235b; 335b) of the tool. The cutter arrangement includes a cutter slot (75; 275; 375), an anvil (80; 280; 380) movable to close the slot comprises an anvil and a cutter blade (90; 290; 390). In use, a cable (10; 210; 310) is held by the grabber arrangement, and thereby moved into the slot which is then closed by the anvil so as to entrap the cable within the slot. The cutter blade is then driven against the anvil so as to cut the cable.
