Abstract 1 Introduction
With dwindling terrestrial energy resources, there's a societal consensus to harness clean, renewable energy. Submarine hydrothermal vents, hosting abundant and unexplored energy potentials, draw international academic scrutiny [1]. Yet, comprehensive research on exploiting their thermal energy systems remains sparse. Existing technologies persist with stability and efficiency challenges. While promising ventures in hydrothermal power generation exist, they grapple with heat loss, instability, limited capacity, and heightened damage susceptibility [2]. This study scrutinizes submarine hydrothermal vents, amalgamating terrestrial closed-loop geothermal technology to resolve challenges and enable efficient energy utilization [3]. Given the complex geology of these… More >

Abstract The electromagnetic losses of submarine cables are mainly caused by the metal shielding layer to prevent the water tree effect and the armor layer that strengthens the strength of the submarine cables. While these losses cause the temperature of submarine cable to rise, and temperature variation will in turn change the conductivity of its metal layer material. In this paper, the electric-magnetic-thermal multi-physical field coupling of the electromagnetic loss variation of the submarine cable is realized by establishing a full coupling system containing Fourier’s law and Maxwell-Ampère’s Law for the photoelectric composite submarine cable. The… More > Graphic Abstract

Abstract Utilizing artificial intelligence (AI) to protect smart coastal cities has become a novel vision for scientific and industrial institutions. One of these AI technologies is using efficient and secure multi-environment Unmanned Vehicles (UVs) for anti-submarine attacks. This study’s contribution is the early detection of a submarine assault employing hybrid environment UVs that are controlled using swarm optimization and secure the information in between UVs using a decentralized cybersecurity strategy. The Dragonfly Algorithm is used for the orientation and clustering of the UVs in the optimization approach, and the Re-fragmentation strategy is used in the Network… More >

Abstract Due to the interaction and corrosion of the seawater, submarine pipelines are easy to be broken to spill oil. The special environment of subsea restricts the technical development of pipeline maintenance. Therefore, the study on the oil spilling model of submarine pipeline is very important for predicting the movement and diffusion of spilled oil, so that oil spilling traces and relating strategies can be determined. This paper aims to establish an oil spilling model of a submarine pipeline, study the movement characteristics of spilled oil in seawater by numerical simulation, and determine the traces, diffusion… More >

Abstract Submarine maneuverability has been analyzed by means of computational fluid dynamics (CFD). This approach provides an alternative, accurate, and cost-effective method for simulating actual flow. The numerical results show that the numerical simulation of the viscous flow related to a moving submarine based on the RANS equation with a relevant turbulence model can not only provide rich flow field details such as flow separation, but also accurately predict its hydrodynamic performance. The present study indicates that CFD can be used to forecast the submarine’s maneuverability in the initial design stage. The present results will be More >

Abstract With the number of submarines increasing rapidly, there are many accidents occurred during submarines’s cruising. Especially the universal attentions to submarine rescue are awaken by the Russian Navy’s second-generation strategic nuclear submarine "Kursk" accident.
One of the important means for submarine rescue is SRC. Since 70th last century abroad, Navy’s submarine rescue armies have been equipped with the SRCs. Entering 21th-century, it is necessary for mating exercises between SRC and disabled submarine(DISSUB) chosen still by Navy’s submarine rescue armies in Navy’s large military drills at home and abroad. The dedicated mating platforms for the SRCs… More >
