L&H deepwater riser is the key equipment of semi-submersible drilling platform or drilling vessel,mainly used for installation and connection between the drilling riser pipes and floating platform or drilling ship, the main function for the drilling riser to establish a top constant tension system, protect the riser and the elimination of floating platform or drilling ship relative drilling vibration pipe sinking motion.L&H provides two types of tensioner, a standard type is fixed on the cantilever beam of the tensioner, the type of products of high tension;The other one is fixed on the Texas platform of the tensioner, the type of products of tension is small, the advantages of platform in emergency situations can be in the shortest time to recover the cantilever, and the tensioner interference.
The deepwater conductor tension unit adopts the perfect combination of the main tension unit and the secondary tension unit,it is very good to achieve the main tension of the compensation and the independence of the operation of the secondary tension unit is guaranteed.Conductor tension units are installed on the most advanced international pressure and displacement sensors, so as to achieve efficient and accurate control.
