Ship and Platform Structures

Marine vessels and offshore installations rely on intricately designed structural systems to endure complex combinations of static and dynamic loads arising from buoyancy, wave action, wind, currents and operational activities. Ship hulls are typically constructed from stiffened panels, longitudinal girders and transverse frames arranged in a continuous girder to resist bending, shear and torsion under intact and damaged conditions. Offshore platforms range from fixed‐leg steel jackets and gravity‐based structures in shallow waters to floating semi-submersibles and tension-leg platforms in deep water. These platforms must reconcile strength, stiffness and weight to maintain stability, fatigue resistance and serviceability across varied sea states. The integration of advanced computational tools—nonlinear finite-element analysis, fluid–structure interaction modelling and data-driven surrogates—alongside targeted experiments has deepened understanding of ultimate strength, hydroelastic response and damage consequences. Probabilistic frameworks and machine-learning algorithms are increasingly adopted to quantify uncertainties in impact, grounding and fatigue scenarios. Such multidisciplinary advances underpin modern classification rules, support resilience against accidental loads and steer the development of crash-worthy hull forms and adaptive protection systems, enhancing safety, environmental protection and continuity of energy supply globally.

A hybrid deep-learning framework now combines ship AIS data with super-element simulations to predict collision damage dimensions—breach length, height and penetration—in under a second, enabling near-real-time navigational support. Probabilistic grounding assessments employ Monte Carlo sampling of vessel speed, seabed geometry and impact parameters to generate distributions of hull-breach extents, informing damage-stability indices and guiding optimisation of bottom-shell arrangements. Coupled fluid–structure interaction studies integrate explicit nonlinear finite-element schemes with potential-flow and RANS hydrodynamics to demonstrate how hydrodynamic restoring forces influence energy absorption and dynamic response during collision and grounding, leading to refined stiffener layouts and impact-resistant hull form strategies.
