Abstract

This work presents the baseline design for the autonomous subsea vehicle capable of traveling at a lower speed of 1 m/s with an operating range of 400 km. Owing to UiS subsea-freight glider's (USFG) exceedingly economical and unique propulsion system, it can transport various types of cargo over variable distances. The primary use-case scenario for the USFG is to serve as an autonomous transport vessel to carry CO2 from land-based facilities to subsea injection sites. This allows the USFG to serve as a substitute for weather-dependent cargo tankers and underwater pipelines. The length of the USFG is 50.25 m along with a beam of 5.50 m, which allows the vessel to carry 518 m3 of CO2 while serving the storage needs of the carbon capture and storage (CCS) ventures on the Norwegian continental shelf. The USFG is powered by battery cells, and it only consumes a little less than 8 kW of electrical power. Along with the mechanical design of the USFG, the control design is also presented in the final part of the paper. The manoeuvring model of the USFG is presented along with two operational case studies. For this purpose, an LQR and PID-based control system is designed, and a detailed comparison study is also shown in terms of tuning and response characteristics for both controllers.

美国水下货运滑翔机:一种大型浮力驱动的自主货运滑翔机

这项工作提出了自主水下航行器的基线设计，能够以1米/秒的较低速度行驶，作业范围为400公里。由于美国水下货运滑翔机(USFG)极其经济和独特的推进系统，它可以运输各种类型的货物在不同的距离。USFG的主要用例是作为一艘自主运输船，将二氧化碳从陆地设施运送到海底注入点。这使得USFG可以作为依赖天气的油轮和水下管道的替代品。USFG的长度为50.25米，横梁为5.50米，这使得该船能够携带518立方米的二氧化碳，同时满足挪威大陆架上碳捕集与封存(CCS)企业的储存需求。USFG由电池提供动力，它只消耗不到8千瓦的电力。在进行USFG的机械设计的同时，本文的最后部分还进行了控制设计。提出了美国联邦政府的机动模型以及两个操作案例研究。为此，设计了一种基于LQR和pid的控制系统，并对两种控制器的调谐特性和响应特性进行了详细的比较研究。

期刊介绍： The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events. Scope: Offshore Mechanics, Drilling Technology, Fixed and Floating Production Systems; Ocean Engineering, Hydrodynamics, and Ship Motions; Ocean Climate Statistics, Storms, Extremes, and Hurricanes; Structural Mechanics; Safety, Reliability, Risk Assessment, and Uncertainty Quantification; Riser Mechanics, Cable and Mooring Dynamics, Pipeline and Subsea Technology; Materials Engineering, Fatigue, Fracture, Welding Technology, Non-destructive Testing, Inspection Technologies, Corrosion Protection and Control; Fluid-structure Interaction, Computational Fluid Dynamics, Flow and Vortex-Induced Vibrations; Marine and Offshore Geotechnics, Soil Mechanics, Soil-pipeline Interaction; Ocean Renewable Energy; Ocean Space Utilization and Aquaculture Engineering; Petroleum Technology; Polar and Arctic Science and Technology, Ice Mechanics, Arctic Drilling and Exploration, Arctic Structures, Ice-structure and Ship Interaction, Permafrost Engineering, Arctic and Thermal Design.
