Abstract
A method is provided for cementing an annular cavity between a subsea well casing and a borehole from a floating vessel. A drill string is run into the casing. An opening positioner attached to the drill string is engaged with a valve in the casing. The drill string is lifted to open the valve. The drill string is positioned to align an isolation packer with the casing valve. An anchor attached to the drill string is set to provide sufficient resistance between the drill string and the casing to operate a motion compensator on the floating vessel. A cement slurry is then pumped into the drill string, out the isolation packer, through the open casing valve and into the annular cavity between the casing and the well bore-hole.
