Abstract: A pipeline unit (1) comprising a pipe member (2) and a pipe coating (3) surrounding the pipe member (2), which pipe member comprises a pipe end (4), and which pipe coating (3) extends along a length of the pipe member and ends at a coating end face located at a distance from the pipe end, wherein a bonding member (8) is provided on the coating end face, which bonding member (8) is attached to the coating end face and made from a material which is different from the material of which the pipe coating (3) is made.

Abstract: A traction device for paying out and retrieving a flexible line including a line mover, wherein the line mover includes at least one movable friction surface, the friction surface in total defines at least two arc sections configured to move the line along with the arc sections, in use the line is wound around the friction surface such that the line has a first contact area being in contact with the first arc section and a second contact area being in contact with the second arc section, and the traction device includes a line controller coupled to the line between the first contact area and the second contact area and configured to control the velocity with which the line in use is fed to the second arc section, and also a method and use of the traction device.
