Our production riser tensioner units prevent the production riser system buckling under compressive loading from self weight and to compensate for ocean currents, waves, and relative movements between the platform and the riser.

Their design employs the hydropneumatic principle and robust and reliable components. The system includes the production riser tensioner units and a control panel. The PRT125 model has a maximum rated tension capacity of 125 t and is designed to accommodate the most common production riser ODs. The control panel also features a panel for monitoring the operation of each production riser tensioner unit.

Specifications
