ABSTRACT:
Offshore platform leg jacket and piling sets having inflatable grout seals with inflation lines extended to the outside of respective jackets and upward to the top of the jackets each equipped with a premature inflation prevention structure low in the inflation line preventing fluid hydrostatic pressure from causing premature grout seal inflation. The structure inserted low in each inflation line is in the form of a rupture disc or, alternately, a pressure controlled relief valve so selected and/or set that the hydrostatic fluid pressure required to burst the rupture disc or to open activate the relief valve is always higher than the maximum hydrostatic pressures the respective grout seals are exposed to.
