 VS. CI. 61 — 46 15 Claims 



A method for grouting the annulue between 

 the c'aaket and piling in the lege of an off- 

 shore struature in which air is introduced 

 to expel water from the lower end of the 

 annulus, and the annulus irs then filled _ 

 from the top with grouting material. Air 

 pressure may be maintained in the annulus 

 sufficient to prevent ingress of water 

 through the lower end of the jacket while 

 grouting material is being introduced. 



[Compressed air is introduced into an 

 annular space existing between the jacket 

 and piling in the legs of an offshore 

 structure so that water is expelled from 

 the annular space through the lower end 

 of the jacket and grouting material is then 

 introduced into the annular space. The 

 introduction of compressed air and grouting 

 material is effected from above the water- 

 line, thus avoiding the necessity of per- 

 forming the grouting operation by divers 

 at the sea bed.]
