Special Issue Information

Dear Colleagues,

Moored floating structures are widely applied in offshore engineering for various purposes, including offshore oil and gas production, ocean renewable energy and aquaculture. Moored floating structures are well suited for non-shallow waters, allowing for installation in more remote and deeper waters far away from land, enabling new offshore opportunities to be realized. Therefore, recent advancements and utilizations of the technology have led to more installations in far deeper and harsher environments. Modelling and simulation are essential tools for adequately understanding the dynamic, nonlinear and stochastic load effects experienced by structures in the offshore environment. This is crucial for the effective and sustainable design, operation and maintenance of moored floating structures. In this context, this Special Issue invites original scientific contributions and review articles on the broad aspects of the modelling and simulation of moored floating structures for all uses. Various applications include, but are not limited to:

  • Offshore oil and gas floating production systems;
  • Floating wind turbines and wind farms;
  • Ocean renewables;
  • Floating piers, harbors and docks;
  • Floating aquaculture plants;
  • Moored ships;
  • Other types of moored offshore floating structures.

Papers that present novel modelling, simulation techniques, and/or novel moored floating structures are highly encouraged.

Fatigue damage caused by cyclic loading is a major concern in engineering applications. Cracks propagated by cyclic loading can lead to catastrophic failure, which can have severe consequences in safety-critical systems. The main objective of the paper is to investigate the residual strength of cracked plate considering fatigue crack propagation under cyclic loading. In this study, a cracked plate model is proposed to study the difference of compressive and tensile residual strength with pre-crack and fatigue crack. The influence factors such as crack length, number of cycles, tensile/compressive cyclic loads, and out-of-plane deformation are considered in the residual strength study of cracked plate. The numerical results can gain insight into the effect of crack propagation on the structural residual strength, with the aim of providing guidance for evaluating the residual strength of cracked components.

The crack closure phenomenon significantly influences low cycle fatigue (LCF) crack growth. The crack closure theory deems that a crack can grow only when the applied load is greater than the fatigue crack opening and closing loads. The revised crack closure theory proposed in this paper provides a new understanding of crack growth: It is no longer the range of stress intensity factor ΔK that controls the crack growth rate, but the effective stress intensity factor ΔKeff. Therefore, it is of great importance to study the crack closure phenomenon of LCF. A combination of experiments and the finite element method (FEM) was used to study the effect of overload on the crack closure effect, and the study was carried out using compact tensile (CT) specimens made of AH32 steel. The FEM was used to obtain the stress changes near the crack tip and the opening displacement changes in the crack trailing area after a single tensile overload, to study the intrinsic mechanism of overload on crack closure, and to obtain the LCF crack opening and closing loads by the nodal displacement method. The effect of overload on crack morphology was observed by using high-magnification electron microscopy in combination with testing. Full article
