“…The findings indicated good agreement between the numerical simulation and the experiments, both in observed phenomena and resistance values, suggesting the promise of their numerical simulation approach for future related studies. Furthermore, Sayeed et al (2017), in their state-of-the-art literature review on iceberg-induced impact forces on offshore structures, with a focus on hydrodynamic interaction, highlighted that the accurate prediction of these forces is currently limited by understanding of hydrodynamic effects near the icebergs.…”

Aging ships and offshore structures face harsh environmental and operational conditions in remote areas, leading to age-related damages such as corrosion wastage, fatigue cracking, and mechanical denting. These deteriorations, if left unattended, can escalate into catastrophic failures, causing casualties, property damage, and marine pollution. Hence, ensuring the safety and integrity of aging ships and offshore structures is paramount and achievable through innovative healthcare schemes. One such paradigm, digital healthcare engineering (DHE), initially introduced by the final coauthor, aims at providing lifetime healthcare for engineered structures, infrastructure, and individuals (e.g., seafarers) by harnessing advancements in digitalization and communication technologies. The DHE framework comprises five interconnected modules: on-site health parameter monitoring, data transmission to analytics centers, data analytics, simulation and visualization via digital twins, artificial intelligence-driven diagnosis and remedial planning using machine and deep learning, and predictive health condition analysis for future maintenance. This article surveys recent technological advancements pertinent to each DHE module, with a focus on its application to aging ships and offshore structures. The primary objectives include identifying cost-effective and accurate techniques to establish a DHE system for lifetime healthcare of aging ships and offshore structures—a project currently in progress by the authors.

“…An appropriate analysis of an FOWT must account for all the sources of the loads on the floating structure and the wind turbine. For reviews on ice loads on floating structures (not discussed in this paper), see, for example, Tuhkuri and Polojärvi (2018) and Sayeed et al (2017).…”

Wind energy industry is expanded to offshore and deep water sites, primarily due to the stronger and more consistent wind fields. Floating offshore wind turbine (FOWT) concepts involve new engineering and scientific challenges. A combination of waves, current, and wind loads impact the structures. Often under extreme cases, and sometimes in operational conditions, magnitudes of these loads are comparable with each other. The loads and responses may be large, and simultaneous consideration of the combined environmental loads on the response of the structure is essential. Moreover, FOWTs are often large structures and the load frequencies are comparable to the structural frequencies. This requires a fluid-structure-fluid elastic analysis which adds to the complexity of the problem. Here, we present a critical review of the existing approaches that are used to (i) estimate the hydrodynamic and aerodynamic loads on FOWTs, and (ii) to determine the structures' motion and elastic responses due to the combined loads. Particular attention is given to the coupling of the loads and responses, assumptions made under each of the existing solution approaches, their limitations, and restrictions, where possible, suggestions are provided on areas where further studies are required.

“…Sayeed et al [1] present a comprehensive review on the literature related to hydrodynamic interaction between drifting ice and offshore structures for the past 30-40 years. In their review, they categorize the problem of drifting ice trajectory and impact with structures into three phases: farfield, near-field and contact phases.…”

Impact scenarios involving a typical drilling rig and glacial ice are studied. The goal is to better identify the important physical effects in modelling the dynamics of glacial ice in presence of waves and a floating platform, whilst improving simulation tools to capture the location and energy of possible collisions. A state-of-the-art numerical model of a typical semi-submersible is developed and calibrated with model tests to represent the drilling rig. A systematic incremental approach is adopted to model the dynamics of glacial ice. Long wave approximation, nonlinear excitation and restoring forces, interaction forces with the semi-submersible, and viscous forces due to flow separation are among the models which are considered step by step. The sensitivity of the resulted collision scenario to the modelling choices is investigated. The possibility of impact with columns, pontoons, and risers are particularly studied. Based on the obtained results, recommendations are made for modelling of glacial ice dynamics in presence of a floating platform.
