OSTI ID:7019713
A method for grouting the annulus between the jacket and piling in the legs of an offshore structure is described. Air is introduced to expel water from the lower end of the annulus, and the annulus is then filled from the top with grouting material. Water may be pumped down the annulus to wash out mud. Some grout may be pushed out the bottom of the annulus to remove mud or to form a bell foundation. (10 claims)
