Technical insights
Explore our technical perspectives on complex offshore challenges. We combine high-fidelity OrcaFlex dynamic modelling, finite element analysis, and practical operational expertise to de-risk installation procedures and support robust engineering decisions.
Steep S-Lay in ultra deep waters
Executing rigid pipelay in ultra-deep water demands rigorous management of dynamic tension and critical stinger tip contact. Through comprehensive OrcaFlex analysis and structural modelling, we formulate offshore procedures that mitigate dynamic pipeline buckling and safeguard product integrity across varying sea states.
Above water tie-in operations
Above water tie-in (AWTI) campaigns require tight coordination between davit lift sequences, vessel motions, and pipe geometry. Our detailed multi-line dynamic lifting and structures deployment analysis ensures lift limits remain safe, local stresses stay within allowable criteria, and field procedures run seamlessly offshore.
Residual strain and fatigue in S-Lay
Plastic deformation through severe stinger curvature can leave critical residual strains that impact long-term pipeline operational life. Our engineering assessments integrate non-linear cyclic loading and advanced fatigue analysis, delivering actionable guidance for offshore procedures and asset integrity verification.
