penetrate the offshore structure 10 to its target depth in addition the side and end friction of the lower foundation section 20 walls in contact with the soil will have a bearing on the effectiveness of the suction to further facilitate installation the lower foundation section 20 can be fitted with high pressure jets 8 at the tip 25 of the lower foundation section 20 the jets 8 are used to spray fluidly at a high pressure into the soil around the tip in order to reduce or eliminate tip resistance and reduce skin friction resistance thereby further facilitating installation given the particular soil and the geometry of the offshore structure 10 installation can be achieved if as described further below 1 excessive flow or piping of water does not occur 2 the soil does not become quick 3 and the under pressure does not exceed the cavitation pressure inside the lower foundation section 20 when operating the pump 42 a hydrostatic gradient will be created in the soil located in the lower foundation section 20 as water moves up through the soil there may also be some soil that moves up the flow of water will need to be restricted to ensure the soil does not become u201c quick u201d i e like quicksand and to keep from producing soil up through the pump 42 if the foundation sand becomes quick it.
