Special Issue Information

Dear Colleagues,

Offshore geotechnical engineering is an intricate discipline that encompasses a variety of challenges, from dealing with deep-sea environmental conditions to ensuring the stability and safety of offshore structures. Central to these challenges is the understanding and characterization of the environment- and energy-related processes that play a pivotal role in the design, construction, and operation of offshore facilities. This Special Issue, titled “Recent Advances in Environment- and Energy-Related Processes in Offshore Engineering”, aims to bring together cutting-edge research, innovative methodologies, and the latest findings in offshore geotechnical engineering.

Contributors are encouraged to submit papers that delve into areas such as the development of renewable marine energy; structure–environment interactions; environmental geomechanics; multiphasic, multiprocess simulation for offshore engineering; and innovative solutions for offshore geotechnics. Manuscripts that present novel numerical models, experimental setups, or case studies that provide insights into aspects of the environmental and energy processes of offshore geotechnical engineering are particularly welcome.

Through this Special Issue, we aspire to foster a deeper understanding of the environment- and energy-related processes that govern offshore geotechnical engineering, ultimately advancing the state of the art in this critical field. The knowledge we gather can significantly influence the design of more resilient offshore infrastructure, ensuring safer operations for challenging marine environments and energies.

We invite both researchers and industry professionals to contribute to this endeavor to build a comprehensive repository of knowledge that bridges the gap between theory and practical application in offshore engineering.

Carbon sequestration through CO2 injection into a formation is an effective strategy for reducing greenhouse gas emissions. In this study, a one-dimensional long reactor was constructed to simulate the CO2 injection process under various sediment temperatures, pressures, and flow rates. The formation of CO2 hydrate and the resulting blockages were investigated in detail through a series of indoor experiments. Due to the increasing driving force for CO2 hydrate formation, reducing sediment temperature and increasing sediment pressure can cause hydrate blockage to form near the injection end, leading to an increase in CO2 injection pressure and a reduction in the storage range. Furthermore, CO2 injection rate has a substantial impact on the pattern of hydrate blockage. A lower injection rate facilitates full contact between CO2 gas and pore water, which helps to increase the formation and blockage degree of CO2 hydrates, thereby decreasing the amount of CO2 injection. The experimental investigation presented in this paper examines the laws of CO2 injection and clogging under various sediment conditions and injection processes on a one-dimensional scale, which can provide valuable insights for the design of CO2 sequestration processes.
