High-Fidelity Modeling for Installation of Subsea Structures in the Splash Zone

3D Computational Domain including Detailed Geometry of a Subsea Manifold

Lowering subsea structures and equipment into the splash zone is a critical part of offshore installation campaigns. In preparation, engineering teams perform many installation analyses to ensure sufficient crane capacity, clearance and accessibility, structural integrity, and equipment/structure stability. Traditional low-fidelity approaches rely on simplified formulations or empirical equations; some consist of model tests to determine wave loads on structures. But these traditional approaches cannot simulate wave-structure interaction nor the dynamic stress and deformation of structure/equipment due to wave slamming. And hence the accuracy is always a key concern. Continue reading
