Disclosed is a tensioner for the controlled clamping and forward movement of an elongate element, in particular for winding/unwinding a cable, a hose, a pipeline or an umbilical on a reception member. The tensioner includes at least one frame that carries three guide boxes arranged around a passage axis. This tensioner includes a unit for maneuvering these guide boxes, in particular second maneuvering unit for the maneuvering in rectilinear, or at least substantially rectilinear, translation of lateral guide boxes, respectively in a direction defining an angle of between 115° and 125°, and preferably between 118° and 122°, with respect to the central plane. These second maneuvering unit includes at least one rocker element including a proximal end mounted so as to pivot on the frame and a distal end mounted so as to pivot on the lateral guide box, respectively about rotation axes extending parallel to the passage axis.

A flexible lance drive device has at least one drive motor in a first portion of a housing and a drive axle projecting across a second portion of the housing carrying a cylindrical spline drive roller. A plurality of cylindrical guide rollers on fixed axles span across the second portion of the housing aligned parallel to the spline drive roller. An endless belt wrapped around the at least one spline drive roller and guide rollers has a generally smooth outer surface and a transverse splined inner surface having splines shaped complementary to splines on the spline drive roller. A bias member supports a plurality of follower rollers each aligned vertically above one of the at least one spline drive roller and guide rollers operable to press each follower roller toward one of rollers to frictionally grip a flexible lance hose when sandwiched between the follower rollers and the endless belt.

A device for transporting elongated metal material comprises two chain drive units with a continuous chain, which are arranged such that the elongated material is passed through between the chains with frictional contact so that the elongated material is moved; two controllable pressure units configured to apply pressure forces to the chains towards each other; at least one controllable adjusting unit which is mechanically connected to at least one of the chain drive units and which is configured to move same in a longitudinal direction of the elongated material during operation. A plant can have such a device, and a process is used for controlling such a device.

A tensioner system holds back elongate products such as subsea pipelines being laid into water. The system comprises at least one endless circulatory track and an array of rollers supporting the track. Each of the rollers of the array is mounted for rotation around a respective shaft. At least one of the shafts comprises a load pin that is arranged to sense loads applied to the surrounding roller in directions normal to an axis of rotation of that roller.

In the case of a caterpillar track drawing machine having a drawing die and a caterpillar track disposed behind the drawing die, which track comprises two drawing chains having drawing tools disposed on chain links of the drawing chains, it should be possible to align the drawing tools of at least one of the two drawing chains jointly with the respective chain link, perpendicular to the drawing line, so that the caliber range can be changed, in simple and operationally reliable manner, between two drawing recesses having different caliber ranges. The latter is also possible if two different drawing recesses of the second one of the two drawing chains are intended for a first caliber range for which the first drawing recesses for at least one of the two drawing chains are intended, or if the drawing recesses of a first one of the two drawing chains deviate from the drawing recesses of a second one of the two drawing chains.

A pipe tensioner for laying or recovering a subsea pipeline comprising at least two opposing continuous tracks able to hold the subsea pipeline, each track having a plurality of pads mounted on the continuous track for contacting the subsea pipeline, characterised in that at least one pad is a load pad comprising one or more load sensors for measuring loading on the load pad during handling of the subsea pipeline.

A cable processing machine includes a cable feeding device for moving a cable in a feed direction. The cable feeding device has a first guide element and a second guide element, between which elements the cable is guided at least in an operating mode of the cable processing machine. The spacing between the two guide elements is selectively variable. A method for laying a cable in the cable processing machine includes moving one or both of the guide elements relative to one another when the cable processing machine is shifted between the operating mode and a cable laying mode.
