Failure Analysis of Marine Structure

Dear Colleagues,

Marine structures are engineering facilities which are carefully designed, constructed, and installed in seaside zones/oceans for the exploitation of different marine resources. In general, these structures have three categories: fixed, mobile, and floating offshore platforms. However, they can be divided into different groups based on their application, material, and supporting system. These structures are generally impractical when it comes to design, considering all types of loads. Moreover, predicting the response of the marine structures due to wind direction, size of the wind, etc. is complex. Therefore, the specialist employs some random variables to design the marine structures for describing the loads, dimensions, structural properties, etc. Other than that, the marine structures are additionally subjected to berthing loads and operational loads. Hence, the correct analysis of these structures is very important. Failures of marine structures and their accessories can lead to serious consequences, including financial losses, delay in delivery time, and a threat to the safety of the people. Therefore, one of the significant design requirements for any marine structure is to have a reasonably long and safe operational life cycle without any catastrophic failure. In other words, the maintenance of marine systems is important during its efficiency period, and most research has been performed to optimize issues or to increase the efficiency of marine systems. Nevertheless, failures still happen, causing financial losses and threatening human lives, particularly in modern structures with weight reduction, but expanded the capacity of load carrying. The engineering practice recognizes typically one or few reasons for the failure of such structures: excessive force and/or temperature-induced elastic deformation, yielding, fatigue, corrosion, creep, etc. As a result, it is essential to identify potential threats in the first step that can affect the integrity of marine structures.

This Special Issue on “Failure Analysis of Marine Structures” focuses on advancing knowledge specifically for marine structures which are made of steel, concrete, composite, or new materials. Topics include, but are not limited to:

• Static and dynamic structural responses including collapse behavior;
• Impact and collision mechanics;
• Fatigue and fracture, creep detection;
• Material selection, corrosion, and structural degradation;
• Formulation and application of design methods and criteria including system reliability analysis, and optimization techniques;
• Inspection, condition and structural health monitoring, repair/replacement and maintenance;
• Methodology and practices for marine structure lifetime extension;
• Resilient design of marine systems;
• Application of machine learning methods and data-driven models for strength and/or load/response predictions of marine structures.
