Offshore Structural Analysis

Offshore Projects

Expert structural integrity analysis for offshore installations—rigs, platforms, and floating units—ensuring safety, compliance, and durability in extreme marine environments through advanced assessment of ultimate strength, fatigue life, accidental impacts, geotechnical stability, and life-extension feasibility.

Floating Structures

Expert Finite Element Analysis for Floating Offshore Structures: Advanced Software, In-Depth Simulation, and Engineered Assurance

Our specialized practice employs the industry-leading power of ANSYS and ABAQUS to deliver definitive, high-fidelity analysis of floating offshore structures. This isn't just routine simulation; it's the application of premier computational tools to de-risk complex engineering challenges in the world's most unforgiving marine environments.

We leverage these advanced platforms for a multi-physics understanding that is critical for integrity and performance: High-Fidelity Hydro-Structural Coupling: We perform detailed coupled fluid-structure interaction (FSI) analyses. This goes beyond applying simple wave loads to a model. We simulate the true, dynamic interplay between complex sea states—including irregular waves, currents, and wind—and the flexible response of the entire floating system (hull, moorings, risers). This is essential for accurately predicting motion characteristics, global loads, and local stress concentrations. Non-Linear and Transient Dynamic Analysis: Floating structures operate in a realm defined by non-linearity. Using ABAQUS's robust solvers and ANSYS Mechanical's dynamic capabilities, we model large-deflection behavior, material non-linearity, and transient events like slamming, green water impact, and sudden mooring line snap-loads. This provides a true picture of structural behavior under extreme and accidental limit states. Advanced Fatigue and Fracture Assessment: We integrate spectral fatigue methodologies with detailed local finite element models. By applying long-term wave scatter data to stress transfer functions derived from global models, we calculate accumulated fatigue damage at critical weld details and complex joints with high precision. Furthermore, we utilize fracture mechanics modules to assess crack propagation and fitness-for-service, supporting life-extension decisions. Mooring and Riser System Integrity: A floating structure's safety is inextricably linked to its station-keeping system. We create integrated global models that include the non-linear stiffness and damping of synthetic or chain mooring lines, assessing mooring line tensions, fatigue, and clump weight interactions. Similarly, we analyze riser systems for wave-induced fatigue, vortex-induced vibration (VIV), and interference. Model Validation and Calibration: Our use of advanced software is grounded in engineering rigor. We validate our numerical models against model test data, analytical solutions, and operational measurements where available. This calibration process ensures our simulations are not just sophisticated, but trustworthy and reflective of real-world physics. The outcome is not merely a report, but engineered assurance. By applying ANSYS and ABAQUS at this depth, we empower clients to:

• Optimize designs for weight, cost, and reliability.

• Demonstrate regulatory compliance with confidence (IMO, ISO, Class Society rules).

• Quantify safety margins for extreme and operational conditions.

• Make informed, data-driven decisions for life extension and asset integrity management.

We transform the computational power of advanced software into a clear, actionable understanding of structural performance, ensuring that floating assets are built and operated to withstand the demands of harsh marine environments for their entire lifecycle.
