The drill string is pressurized, the tool is unlatched, and the tool is driven ~2.9 m out of the flapper tube until circulation is established. D. The BHA is raised 2.0 m, giving the MDHDS approximately ±3.0 m of heave leeway. E. The ERS is lowered and relatched. F. The MDHDS is brought back to the surface.
