Grouting annuli in offshore platforms.

摘要

A grouting method and arrangement using aqueous solutions of alkali silicate materials confined between a pair of pile seal assemblies (42, 44) in sealing the annular space (70) formed between either a jacket leg or pile sleeve (31) and a pile (20) driven therethrough (or similar annular space of an offshore platform) to support a column of grout thereon so that the annular space (80) may ultimately be filled with grouting material.
