Drilling Risers

MHWirth has a long track record of delivering efficient and reliable drilling riser systems, globally recognized as the fastest drilling riser system, with proven track records showing up to 12 joints per hour.

The QTR™ connector is the key feature of the MHWirth riser system, allowing the fast and easy connection of joints when running a riser string. QTR™ connectors are available in two main versions QTR3500 and QTR4000LS. The QTR4000LS is the latest generation with load sharing capabilities and an easily removable lock ring.

During subsea operations increased efficiency and uptime and safe equipment make the difference. MHWirth’s QTR™ drilling risers do not require heavy tools to connect or disconnect the riser during tripping operations drastically reducing the risk of personnel injury and improving the overall work environment of the rig.

Bolts and preloading the connector are a thing of the past. Our drilling riser connector is positively confirmed closed or open by an index pin; increasing the safety of riser connection operations.

Our drilling riser’s open and close operations increase uptime by taking the connection time down to a minimum and out of the critical path; even hands-free make-up of connectors is available.

MHWirth’s RiCon™ solution for condition based maintenance offers improved reliability, availability and reduced OPEX by up to 30% over a 20 year riser lifetime. For further details see the link below
