Thereafter the air or nitrogen pressure in the annular space is relieved to permit a predetermined volume of water to reenter the lower end of the jacket and while maintaining the pressure in the annular space grouting material is injected thereinto to commingle with the predetermined water volume to form a plug at the lower end of the jacket. Thereafter the gas pressure is relieved from the column and additional grouting material is then inserted thereinto to fill the space between the plug and the upper end of the column.，下面是Method of grouting offshore structure专利的具体信息内容。

权利要求

1. A method of grouting an offshore structure having at least one supporting leg including a tubular jacket extending downwardly from above the waterline to the seabed and a piling driven through said jacket into the seabed with an annular space existing between the inside of the jacket and the piling, said method comprising the steps of: a. sealing the upper end of the jacket to the piling so as to close the annular space at the upper end of the jacket; b. introducing compressed gas into said annular space at a point adjacent the upper end of the jacket and above the waterline so as to expel water from said space through the lower end of the jacket; c. relieving the compressed gas from the annular space to accommodate the reentry of water through the lower end of the jacket until the water in the annular space at the lower end of the jacket reaches a predetermined height; d. introducing fluid grouting material into said annular space at a point adjacent the upper end of the jacket while simultaneously maintaining air pressure in the annular space to maintain the predetermined water level in the lower end of the jacket so as to form a plug in the annular space and seal off its lower end; e. thereafter releasing the compressed gas pressure from the annular space; and f. introducing additional fluid grouting material in the annular space adjacent the upper end of the jacket and permitting it to set to fill the annular space.
