Limar Limar: Motorhead Assembly (Mha)

The document discusses a second generation LiMAR Motorhead Assembly that houses check valves, a hydraulic disconnect, and a dual circulation sub in a combined unit. It has increased pressure rating and technical enhancements over the standard product. The MHA is designed for use in BHAs below the CT connector to provide double barrier protection and dual circulation capabilities in height restricted rig-ups, especially for high pressure applications like fishing, milling, perforating, and setting operations.
