Jack-up units equipped with circular can shaped footings known as spudcans have been widely used for offshore drilling activities. Before each mobilization, an evaluation of the spudcan penetration and potential failure risks during preloading is performed
Leg penetration analysis based on existing site works is performed in the following steps
Brief study of soil investigation and geophysical survey available for the area and the project location including site and project description and scope of geotechnical studies
Reviewing the general specification of the project
Brief study of Site Exploration including the method of drilling exploratory boreholes and insitu tests
Brief study of Laboratory test methods and results including onboard tests and those performed in a central laboratory
Reviewing Subsurface Condition including the type and thickness of soil layers and their specifications
Engineering Analysis including
Review the available Design Soil Parameters for Spudcan Penetration Analysis
Review the methodology assumptions and limitations of LPA
Review the spudcan Geometry and Loading
Spudcan Penetration Prediction and LPA
