Special Issue Information

Dear Colleagues,

Offshore technology and geotechnics are key to the development of renewable energy, as they have been for the oil and gas industry for decades. However, the increasing complexity of offshore structures, exploration of new energy generation sites, climate change, and health and safety concerns have necessitated a deeper understanding of the above subject. The aim of this Special Issue is to disseminate innovative and original papers that extend current knowledge and expertise to support advancements in the planning, design, construction, and use of offshore structures and energy systems. Original papers based on practise, theory, experiments, and numerical analysis are welcome, as are papers on project case studies and emerging technologies.

This Special Issue covers, but is not limited to, the following topics:

  • Engineering geology of offshore sites;
  • Renewable energy;
  • Offshore wind farms;
  • Environmental and geological hazards, e.g., volcanicity, tsunamis, subsea landslides, faults, and sinkholes;
  • Mechanics of offshore soils and rocks: identification, classification, sampling, and testing;
  • Offshore surveys; geophysical and geotechnical surveys, penetration testing, and data interpretation;
  • Marine installations and effects on sea life;
  • Climate change and sea level rise effects on marine structures;
  • Types of offshore structures: planning, design, construction, operation, and decommissioning [man-made islands, jack up platforms, jacket structures, gravity platforms, offshore pipelines, caissons of different types, piled and mono-pile foundations in shallow waters, tethered foundations in deep waters, anchors, and undersea cables];
  • Static and dynamic soil–structure interactions;
  • Wave action, liquefaction, and scouring effects on structures.

This study evaluates the serviceability of floating structures designed for marine cities by incorporating wave-dissipating modules. Small-scale model tests in a 2D wave flume were conducted to compare the serviceability of structures with and without these modules under different wave conditions (1-year and 100-year return period waves). The results showed that wave-dissipating modules significantly reduced vertical acceleration, with reductions of approximately 44~45% levels for 1-year return period waves and 54~57% levels for 100-year return period waves. When a topside building was included, the reductions were similarly pronounced, reaching 64% and 63~64% levels for 1-year and 100-year return period waves, respectively. The modules also mitigated inclination (angle), with reduction rates ranging from 55~77% levels, depending on wave conditions and the presence of a topside building. These findings suggest that incorporating wave-dissipating modules around the periphery of floating structures can enhance their serviceability by creating more comfortable and stable environments for human activities, while also improving the stability of the structures themselves. Future research should focus on scaling up the model tests and conducting field experiments to validate these findings under real conditions, as well as optimizing module designs for different wave conditions and structural configurations.

This study is aimed at the complex deformation response characteristics of deep soil in the processes of excavation and support of round sand foundation pits. The displacement of the diaphragm wall during the excavation and support of the foundation pit was monitored in a round foundation pit project at the west anchorage of Humen Second Bridge. A full-cycle model of foundation pit excavation was established, and a new method for parameter checking based on the principle of three-factor (c, φ, E) multi-level orthogonal experimental design was proposed. Dynamic calibration parameters based on construction monitoring data were obtained. The characteristics of the uplift at the bottom of the foundation pit and the effective plastic strain of the soil before and after the steady-state seepage conditions were applied and analyzed. The most dangerous working conditions (Conditions 5–6: construction of the fourth layer of lining and excavation of the fifth layer; construction of the fifth layer of lining and excavation at the sixth layer) existed during the excavation and support of the foundation pit. The research method can provide a great practical guiding significance for covering lack of monitoring data at the construction site and early warning analysis on foundation pit excavation.
