Abstract
An apparatus and method for pressurizing the inside of tubular members of an offshore structure that are immersed in sea water so that the internal pressure resists the hydrostatic pressure of the sea water. To achieve this internal pressure, gas is generated automatically on the inside of the members as the structure descends to its in-place location. The gas can also be used to deballast a tubular member.
