KA Engineering Group utilises FE methodology for Drilling and Completion and Workover riser analysis to capture accurately the interaction between the various riser components such as riser pipe, conductor and casing and inner strings and soil interaction. KA delivers analysis and design of drilling and completion and workover riser services to Operators, Drilling Contractors and Riser Suppliers. Our Engineering analysis and design is performed using industry standard FE software such as Flexcom, Orcaflex, DeepRiser, Modes, Shear7, VIVA, ANSYS, ABAQUS and a range of validated KA Engineering Group proprietary in-house pre and post processing software tools.
