The MR - 6H SE is a 3.5 million pound rated (API class "H") connector. It is a completely automated connection. The hydraulic spider makes and breaks the connection in under a minute without intervention of rig floor personnel. It is safe and efficient. One of the most reliable and advanced marine riser systems in today's market is VetcoGray's HMF system. The HMF connection is fully preloaded and ideally designed for deepwater drilling in a harsh environment. The MR - 6E is lightweight, simple to operate, and fast to run.

Design Philosophy

The MR - 6H SE is simple, with very few parts, utilizing field proven concepts and profiles which have provided many years of exemplary service. This is a highly preloaded coupling with an efficient load path. The modularized, hydraulically operated handling spider makes and breaks the connection which minimizes intervention of rig floor personnel. The spider design allows quick change out of key subassemblies if required during riser running operations.

Applications
