#Orcaflex flexible riser verification

Through the integration of global and local flexible riser analysis models, we have developed methodologies to predict flexible riser fatigue at key locations using trained algorithms and real-time measured data.

Machine learning algorithms are now helping us manage in-service flexible risers. We have contributed to and led flexible pipe root cause investigations by applying a methodological approach and independently leading a process that has contributed to a unique in-house knowledge base. Our experience includes managing flexible pipe non-metallic materials compatibility testing, metallic wires fatigue testing and investigative dissection of flexible pipe sections retrieved from the field. Flexible Riser Integrity Management & Life ExtensionР”В®xtensive industry research on flexible pipe degradation in recent years has provided invaluable inputs that can now be applied to risk-based assessments for flexible pipelines and risers to improve integrity management.Р”СћH has developed and optimised testing, inspection and monitoring programmes to better detect structural degradation of critical components and interfaces and measure flexibles and umbilical integrity. We can also manage the design and manufacture of generic equipment such as bend stiffeners and end terminations. With an extensive subsea equipment engineering track record, we engineer system-specific ancillary equipment, including buoys, arches and tethers. We also support retrieval and decommissioning projects.

We provide delivery management support from the preparation or verification of material and manufacturing specifications through all stages of purchasing, manufacturing, material and component testing, transport and installation. We also target transparent design and support the development of thorough documentation, which facilitates future engineering assessments should actual operating conditions change. Equipment Engineering & Delivery ManagementР”В«eing independent of manufacturers, we work with operators and installation contractors to ensure that vendor-developed flexible pipe and umbilical solutions are suitable for their intended service. Time-domain finite element cross-section analysis using BFLEX for flexibles and UFLEX for umbilicals helps us determine local tensile and pressure armour wire stresses and perform rainflow fatigue calculations.

We also have advanced methods for flexible riser fatigue analysis that offer the benefits of a more realistic random sea global analysis as opposed to a conventional and often over-conservative regular wave/histogram approach.

Our substantial experience means we can minimise analysis requirements, methods and computational power to process vast load case matrices quickly and reliably to help us optimise flexible riser configurations efficiently. This helps reduce unnecessary design conservatism and ensure long-term fatigue resistance during design or life extension projects. In other project phases, it enables us to reliably assess vendor designs and provide our technical verification as subject matter experts. Design & AnalysisР”Р‡lexible pipe expertise and sophisticated tools and analysis methods allow us to perform a structured concept development, feasibility assessment or preliminary design. We are comfortable working with any standard configuration or developing new/novel configurations for both O&G and renewable energy applications. We have experience in all major offshore exploration regions, in shallow to ultradeep water, and with old and new pipe designs. Our collaborative approach has allowed us to gain in-depth knowledge and expertise that adds value to every flexible pipe and umbilical project. From the conceptual stage to life extension projects, we work with all types of operators, EPCI contractors, and directly with OEM. Flexible pipes are complex structures that require specialist engineering and a multi-disciplinary team to ensure an optimised design, careful manufacturing, reliable installation, operation, and long-term integrity.
