Non-terrestrial network (NTN) is a trending topic in the field of communication, as it shows promise for scenarios in which terrestrial infrastructure is unavailable. Unmanned autonomous intelligent systems (UAISs), as a physical form of artificial intelligence (AI), have gained significant attention from academia and industry. These systems have various applications in autonomous driving, logistics, area surveillance, and medical services. With the rapid evolution of information and communication technology (ICT), 5G and beyond-5G communication have enabled numerous intelligent applications through the comprehensive utilization of advanced NTN communication technology and artificial intelligence. To meet the demands of complex tasks in remote or communication-challenged areas, there is an urgent need for reliable, ultra-low latency communication networks to enable unmanned autonomous intelligent systems for applications such as localization, navigation, perception, decision-making, and motion planning. However, in remote areas, reliable communication coverage is not available, which poses a significant challenge for intelligent systems applications. The rapid development of non-terrestrial networks (NTNs) communication has shed new light on intelligent applications that require ubiquitous network connections in space, air, ground, and sea. However, challenges arise when using NTN technology in unmanned autonomous intelligent systems. Our research examines the advancements and obstacles in academic research and industry applications of NTN technology concerning UAIS, which is supported by unmanned aerial vehicles (UAV) and other low-altitude platforms. Nevertheless, edge computing and cloud computing are crucial for unmanned autonomous intelligent systems, which also necessitate distributed computation architectures for computationally intensive tasks and massive data offloading. This paper presents a comprehensive analysis of the opportunities and challenges of unmanned autonomous intelligent systems in UAV NTN, along with NTN-based unmanned autonomous intelligent systems and their applications. A field trial case study is presented to demonstrate the application of NTN in UAIS.

Offshore oil reserves are abundant, most of which are concentrated on the continental shelf, with broad development prospects. Offshore oil and gas platforms used to use offshore oil are called offshore platforms. Compared with marine facilities, marine platforms have the characteristics of harsh natural environment, small space, large investment and high technical requirements. Accidents such as pressure vessel leakage, platform damage, fire and explosion on offshore platforms will cause huge property losses and casualties. The high risk of safety accidents on offshore platforms requires more perfect safety measures. The purpose of this paper is to study the marine engineering safety analysis based on the joint probability model of wind and waves. This paper proposes a safety analysis method based on a probabilistic test model to conduct quantitative safety analysis of ship technology and improve the analysis performance. The research content focuses on the following points: Firstly, the density concentration of the cylindrical foundation, the SQP optimization method and the improvement of genetic algorithm are applied to the overall size optimization design of the cylindrical foundation. Under the conditions of satisfying the strength, stiffness and stability of the foundation, the design optimization and topology optimization are generated, and the finite element method is used to carry out the local optimization design of the large-diameter cylindrical foundation power transmission system. Finally, to demonstrate the reliability of the results and the validity of the method, this paper validates the performance results using a traditional family tree and compares the entire model-based approach with traditional security methods. The method adopted in this paper can carry out a comprehensive safety analysis of complex systems, the calculation results are reliable, and the efficiency of safety analysis is improved. IntroductionOffshore oil reserves have increased, with proven reserves reaching 38 billion tons. It is
