10 CASTOR DRILLING SOLUTION AS OUR SERVICES At the heart of CDS is our unending drive to make the big difference to our customers. What makes that possible is over 100 years of accumulated knowledge, deeply committed people and industry leading solutions. Through our knowledge and experience, we work with our customers to create solutions that enable them to attain their objectives. RISER ANALYSIS SYSTEM SIMULATIONS MECHANICAL INTEGRITY ANALYSIS We specialize in riser analysis of the overall riser system in combination with a detailed model of the top side equipment, non-standard riser system or optimization of riser system configuration. Key objectives are operating conditions and feasibility of critical components. We also analyze the riser tensioning systems capability to lift the Riser Stack and LMRP of the BOP in a controlled motion during a disconnect sequence. A detailed hydraulic model of the tensioning system and mud flow is made specific for each project. The 3D dynamic simulations integrates vessel motion, machine mechanical components, pneumatics, electronics, hydraulics as well as control systems that accurately accounts for interactions between all subsystems. All system parameters are available for analysis after simulation, raising system knowledge to a new level, and significantly reducing the unknown unknowns. We provide expert consultancy services to determine the root cause of failures and to ensure optimal service life of mechanical components in an offshore environment. We deliver Failure Analysis, Metallurgical Assessments, Corrosion Mitigation and Tribological Analysis and engineering services based on state-of-the-art developments, recent research and extensive offshore systems experience.
