Offshore jacket platforms are lattice-type marine steel structures extensively used for Oil & Gas production in water depths between 20.0 and 90.0 m. These jacket structures are fixed to seabed using large diameter steel tubular piles which requires exceptional design and installation skills to withstand adverse geotechnical conditions and extreme environmental loads. These piles are generally in the range of 1.5–2.8 m outer diameter, up to 101.0 mm thickness, and are generally driven deep up to 100.0 m and beyond into the soil below the seafloor. These piles are designed for combined loads arising from gravity loads due to self-weight and topside facilities and lateral loads generated due to the action of waves, currents, and winds. The design of any foundation system is preceded by a detailed geotechnical site investigation. In this paper, for a specific site in the Western Indian Offshore, the soil investigation and engineering analysis up to 124.8 m depth below the seafloor has been discussed. Based on the assigned design parameters, the axial pile capacity of the pile is calculated as well as the pile driveability assessment is carried out for ensuring smooth installation of piles.
