Reach rod grouting system

摘要

An offshore marine combination reach rod and grouting system wherein a reach rod extended from the upper end of an offshore platform leg or piling and piling sleeve to a flood valve connected to the lower end of a leg annulus passes through one or more tee connections as part of a grout feeding system to the leg annulus. The reach rod in the form of a hollow pipe is connected through flexible lines to flush water and grout feeding sources that permit twisting of the reach rod pipe to open and close the flood valve.
