Predictability and consequential safety of jackup rigs during installation and removal remain non-trivial issues for the industry despite larger deployment of jackup rigs and operations in emerging frontier regions with more complex soil conditions. Jackup foundation hazards such as unpredicted leg penetration, rapid leg penetration, punch-through, spudcan-footprint interaction and leg extraction difficulties continue to occur in spite of the industry stepping up efforts to better control of the risks. Apart from improvements of the installation guideline and practice within the industry as well as implementation of proper site specific assessments, safer performance of jackup rigs may be achieved through advancement in jackup instrumentation technology. In the present paper, a new instrumentation technology integrated with jackup rigs is proposed to assist the jackup operators in making decision and taking measures to prevent or mitigate potential geotechnical hazards, particularly punch-through.
