Tensioner

The tensioner component is available for elastic contact surface description only.

The function of the tensioner is to grip and apply tension to the pipeline during the lay operation.

In dynamic analysis the tensioner accounts for the pipeline pay out or pay in to prevent large oscillations in the pipeline tension.

This is modeled as a dynamic boundary condition with respect to the applied axial force, eg. the applied load is T0 plus/minus a dead band range.

Outside the dead band range the load is constant. The applied load which acts in the longitudinal direction of the pipe, is formulated as a discrete element load.

During static analysis the tensioner applies a constant load, T0, to the pipeline.
