Aero-SERVO-hydroelastic<\/strong> SIMULATIONS for fatigue analysis and remaining useful life<\/strong><\/h2>\n\n\n\n

CompassIS offers specialized services for the analysis, design, verification, and optimization of floating structures<\/strong>, including applications in offshore wind energy<\/strong> and oil and gas<\/strong>, as well as the design and analysis of vessels<\/strong>. This service provides accurate, reliable technical results adapted for use in certification processes.<\/h3>\n\n\n\n

WHAT IS IT? <\/strong>
This turnkey consultancy service is an evolution of the hydroelastic strong coupling within seakeeping application Tdyn SeaFEM<\/a> and FEA application Tdyn RamSeries<\/a>, together with tools like OpenFAST<\/a>, providing clients with advanced engineering calculation software, as well as the technical knowledge and expertise to address these highly complex technical problems.<\/p>\n\n\n\n

Using these powerful tools, CIMNE Naval<\/strong>, UPM-CEHINAV<\/strong>, and COMPASS Ingenier\u00eda y Sistemas<\/strong> have developed a methodology based on Reduced Order Modeling (ROM), enabling the efficient calculation of stress, fatigue damage results and remaining useful life, accounting for all coupled effects (mooring loads, wind, currents, and waves) in the time domain.<\/p>\n\n\n\n

WHAT IS ITS ADDED VALUE?<\/strong>
The methodology offered by this service revolutionizes the design, optimisation and verification process:<\/p>\n\n\n\n

    \n
  1. Drastically reduces computational times <\/strong>for structural dynamic analysis, which is typically a bottleneck, allowing the calculation of the large number of load cases required to analyze fatigue damage.<\/li>\n\n\n\n
  2. Solves the challenge of integrated load analysis <\/strong>for Floating Offshore Wind Turbines (FOWT).<\/li>\n\n\n\n
  3. Helps reduce costs <\/strong>(calculation times and result volumes) by providing near real-time insights into the design, enabling continuous optimization.<\/li>\n\n\n\n
  4. Can be used during the structural design phase <\/strong>to evaluate strength, fatigue damage, and remaining useful life, and can even be incorporated as a digital twin <\/strong>of the platform.<\/li>\n\n\n\n
  5. The analysis methodology complies with current regulatory codes from major Classification Societies<\/strong>, such as:\n
