ABSTRACT:
A method of placing concrete into a steel encasement constructing an offshore structure. The steel encasement is erected. A plurality of first concrete injection holes are formed through the steel encasement in a heightwise spaced manner. The concrete is injected through the lowest disposed concrete injection hole into the erected steel encasement to a level below another concrete injection hole disposed just above said lowest disposed concrete injection hole. Then, the injection step is repeated in connection with a subsequent first concrete injection hole nearest to the level, to which the concrete has been placed, for placing the concrete into the steel encasement to a predetermined level.
