Mastering Subsea Pipeline Freespan Assessment and Remediation: A Practical Approach
Through an array of practical examples, learners will develop expertise in the assessment and remediation of freespans in subsea pipelines. This proficiency is invaluable for industry practitioners, imparting the skills to identify, evaluate, and rectify freespans effectively, thus ensuring the dependability and integrity of subsea pipelines. Opting to study with us offers delegates a uniquely tailored learning experience, accentuating practical applications and equipping them to adeptly navigate real-world challenges in the subsea pipeline space.
Module Highlights
Day 1 - Unveiling Subsea Pipeline Freespans: Dynamics, Assessments, and Limit States
Delve into the intricate world of subsea pipeline freespans with a detailed exploration of formation methods and failure mechanisms. The journey continues as we unravel the dynamics of spans, investigating vortex-induced vibrations, failure modes, and the calculation of natural frequencies through an approximate response model. Gain insight into the presentation of response envelopes and an overview of assessment levels. The course progresses to screening assessments, where reduced velocity calculations are examined along with their applications and limitations. Concluding this exploration is a comprehensive look at ultimate limit state (ULS) assessments, covering static stress responses, global and local buckling, and third-party interactions.
Day 2 – Navigating Subsea Pipeline Freespans: From Fatigue Assessments to Remediation Strategies
Embark on a comprehensive exploration of subsea pipeline freespans with an in-depth examination of fatigue limit state (FLS) assessments. Uncover the intricacies of single and multi-mode responses, delve into cross-flow induced in-line vortex-induced vibrations (VIV), explore acceptance criteria, and navigate the calculations of fatigue life. The course proceeds to scrutinize span assessment software, including DNV FatFree, Plus-One, SAGE Profile, and Finite Element Analysis (FEA). Concluding this immersive journey is an insightful discussion on remediation, covering berm and mattress stability, along with the prediction of future scour scenarios.
