In this study the penetration of spudcan foundation for “jack-up rig” type offshore oil platform into a uniform clayey seabed is investigated with three-dimensional finite element modeling (Abaqus 6.14) using coupled Eulerian-Lagrangian method that can handle large strain problems. One of the goals of this study is to compare the penetration-bearing resistance behavior of spudcan obtained by numerical study with the method suggested in InSafeJIP design guideline. For the spudcan geometry and soil properties used in this study, based on the three dimensional finite element analyses, the required penetration depth for a target bearing capacity of spudcan is less than that required by analytical method in InSafeJIP guideline. The second goal of the study is to explore the effects of some geometrical and soil variables on spudcan bearing resistance-penetration behavior. The variables in this study are spudcan diameter (7.5 to 15.0 m), the surface roughness of spudcan (roughness coefficient of 0 to 1.0) and undrained shear strength of clay (20 to 80 kPa). Understanding the relations between these factors and penetration behavior may help in future studies on enhanced and economical design of spudcans.

Three-Dimensional Finite Element Modeling for Spudcan Penetration into a Clayey Seabed Emren, Volkan; Huvaj Sarıhan, Nejan; Tuncay, Kağan (2017-03-15) In this study the penetration of spudcan foundation for "jack-up rig" type offshore oil platform into a uniform clayey seabed is investigated with three-dimensional finite element modeling (Abaqus 6.14) using Coupled Eulerian Lagrangian method that can handle large deformation problems. One of the goals of this study is to compare the penetration-bearing resistance behavior of spudcan obtained by numerical study with the method suggested in InSafeJIP design guideline. For the spudcan geometry and soil prope...
Development of an applied element based tool for prediction of collapse behavior of concrete dam monoliths Hassan Zada , Hamidullah; Arıcı, Yalın; Department of Civil Engineering (2020-9-24) In this study, conducted with the support of TUBITAK under the grant 116M524, a software framework with a web-based graphical user interface is developed for the investigation of the seismic behavior of concrete gravity dams. Using a modified discrete element technique, one of the primary goals of the developed tool is to simulate extensive cracking on concrete dam monoliths followed by sliding, rocking and loss of stability. The graphical user interface for using this engine is prepared in HTML, Java...
Advanced workflow for multi-well tracer test analysis in a geothermal reservoir Bayer, Peter; AKIN, TAYLAN; Akın, Serhat (2022-05-01) Interpretation of tracer tests in geothermal reservoirs is carried out by fitting the measured data either with simplified two-dimensional (2-D) analytical solutions or with complex numerical models. Available analytical solutions commonly only describe isotropic conditions in 1-D or 2-D, which is generally unsatisfactory to construct realistic reservoir models. Moreover, due to the large spatial and temporal scale of a tracer test in deep reservoirs, the concentration levels measured in the field are relat...
Three dimensional finite element modeling for the spudcan penetration into clayey seabed Emren, Volkan; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2015) The penetration of the foundation for “jack-up rig” type offshore oil platform (spudcan) into a uniform clayey seabed is studied with three dimensional finite element modeling (Abaqus 6.14) using Coupled Eulerian Lagrangian method. Although there exists some analytical methods (InSafeJIP etc.) for the calculation of the spudcan bearing capacity, they frequently underestimate or overestimate the bearing capacity due to simplifications involved. For the spudcan geometry and soil properties used in this study,...
A stochastic approach in reserve estimation Kök, Mustafa Verşan (Informa UK Limited, 2006-12-01) Geostatistics and more especially stochastic modeling of reservoir heterogeneities are being increasingly considered by reservoir analysts and engineers for their potential in generating more accurate reservoir models together with usable measures of spatial uncertainty. Geostatistics provides a probabilistic framework and a toolbox for data analysis with an early integration of information. The uncertainty about the spatial distribution of critical reservoir parameters is modeled and transferred all the wa...
