Utilizing Advanced Modeling:

At Vedam, we leverage sophisticated finite element modeling to replicate the floating collar and mooring system of fish cages. The primary structure, comprising HDPE pipes interconnected with brackets and stanchions, forms a stable foundation for the fishnet pen. To ensure structural integrity across varying conditions, a sinker system with weights maintains the cage’s shape and volume.

Hydrodynamic Insights:

Our analysis commences with the development of a hydrodynamic model using OrcaFlex software. This model calculates critical mooring and hydrodynamic loads, providing indispensable insights into the cage’s behavior. These load data are then integrated into a structural finite element analysis (FEA) model, enabling comprehensive assessments of structural responses and strength under diverse environmental scenarios.

Compliant Design:

Adhering to NS9415 guidelines, our mooring system is meticulously crafted with four anchor lines, each linked to an anchor chain and mooring rope connected to a floating buoy. Capacity calculations, rooted in worst-case scenarios, ensure the system’s resilience against extreme conditions, fostering stability and longevity.

Global and Local Analysis:

Our assessment encompasses both global and local considerations. Initially, a solid model incorporates buoyancy pipes and the collar, followed by a fine-mesh local analysis focusing on critical areas such as brackets. Stress and deformation results from the global analysis are rigorously evaluated against HDPE system acceptance criteria for various weather conditions. Additionally, we scrutinize potential accidental scenarios, prioritizing safety and reliability.

Ensuring Structural Integrity:

Our approach underscores the paramount importance of structural integrity across diverse conditions. By integrating global and local assessments, we prioritize safety, resilience, and strict compliance with established guidelines. This comprehensive methodology for fish cage mooring and structural assessment optimizes aquaculture practices while fostering sustainability and reliability in fish farming endeavors.

Conclusion:

In conclusion, Vedam’s comprehensive approach to mooring and structural assessment offers a robust foundation for enhancing stability and sustainability in aquaculture operations. By prioritizing optimization and compliance with industry guidelines, we empower stakeholders to navigate challenges with confidence, ultimately promoting equitable and reliable fish farming practices.
