Title: Method of grouting offshore structures

Abstract

Submerged cavities such as occur in jacketed pilings in offshore structures are grouted by the sequential use of materials with initially decreasing densities, the heaviest of which is lighter than water, followed by the use of conventional grouting materials of greater density. The first material is quick setting and generally water-immiscible. Water is thus displaced downwardly out of the cavity by the lighter material. The first material is forced to the bottom of the cavity and allowed to set as a plug to support the conventional grouting materials.
