WitrynaPRT systems are in principle scaled-down DRT systems applying tension to stiff production risers on board floating production vessels like tension leg platforms (TLP). These TLPs have less vertical heave movements than drilling vessels thus shorter cylinder stroke lengths (max 2 m). WitrynaRiser wear is primarily a function of riser curvature, which is dependent on riser stiffness, environmental loading, vessel offset, drilling operational parameters and drilling mud properties. Wear allowance and windows for conducting drilling operations can be defined prior to wear analysis.
