Special Issue Information

Dear Colleagues,

In recent years, great efforts have been made to improve coastal and offshore marine engineering following the trends in developing renewable energy in the ocean, with marine geotechnology being one of the most important aspects of this. More advanced models of geohazards and geotechnical analysis on marine structures are proposed to increase reliability and reduce cost and/or risk. These developments require advanced and innovative site investigation technologies and numerical methods to fulfill design requirements.

Considering the needs of nearshore and offshore engineering societies, this Special Issue aims to present the latest developments in advanced and innovative techniques in seabed site characterizations and/or numerical simulations for seabed-based structure analysis or design. Topics related to advanced site characterizations may focus on but are not limited to underwater geophysical methods, sampling technologies, in situ testing, highly efficient geotechnical survey methods, etc. Topics related to advanced numerical methods for seabed-based structure analysis or design could be related to marine foundations, anchors, cables, pipelines, breakwaters, etc. Case studies related to site characterizations and the design of seabed-based structures are also within scope.

Seabed surveying is the basis of engineering development in shallow waters. At present, geophysical survey methods mainly utilize sonars for qualitative surveying, which requires the calibration of the results found through in situ drilling and sampling. Among them, the parameters required for engineering designs are obtained from either in situ tests or laboratory experiments of soil samples retrieved from drilling. However, the experience from onshore applications shows that the physical quantities obtained through quantitative geophysical survey methods for shallow waters can be indirectly used to estimate engineering parameters or directly as parameters for engineering evaluation, which has high application potential. This review analyzes various geophysical survey methods for nearshore site characterization (i.e., side-scan sonar, single/multi- beam sonar, sub-bottom profiler, seismic reflection method, and underwater magnetometer) and challenges in their application, and introduces quantitative geophysical survey methods (including the underwater seismic refraction method, seismic surface wave method and underwater electrical resistivity tomography) that are worth focusing on for future development. Three application difficulties have been identified, namely, the lack of operational efficiency, appropriate operational equipment and systems, and sufficient guidance for experimental shallow sea applications. It is hoped that comprehensive discussion of these challenges will increase awareness leading to engineering improvements in the surveying and measuring capabilities in shallow waters, further reducing the risk of geotechnical hazards.
