Hence, alternative localization methods are imperative for both navigation and operational purposes. This study thoroughly reviews sensor technologies for underwater localization, including sonar, Doppler velocity log, cameras, and more. Different operations necessitate distinct localization accuracies and vehicle and sensor choices. Environmental factors, such as turbidity, waves, and sound disturbances, impact sensor performance. Conclusions are given on the coincidence between operational requirements and sensor specifications, with special attention to the open concerns. These considerations include aspects such as the line of sight for acoustic positioning systems and the requirement for a feature-rich environment for visual sensors.

Effective vibration suppression of these vibrations has always been a key issue in research. In this study, two of the most commonly used passive structural control devices used to mitigate vibration in FOWTs are considered: tuned mass dampers (TMDs) and tuned liquid column dampers (TLCDs). A comparative evaluation of their vibration mitigation performance applied to the FOWT is carried out. First, to implement the optimal design of parameters for the TMD and TLCD, simplified 3-degree-of-freedom (DOF) mathematical models for the FOWT with the TMD/TLCD are derived and established. The simplified mathematical model is further validated, and the optimal design and parameter study of the TMD and TLCD are investigated using the 5 MW barge FOWT as the benchmark research object. Evaluations and comparisons of the vibration control performance of TMD and TLCD are performed on the basis of fully coupled time domain analysis in OpenFAST, considering the FOWT in operational, nonoperational, and extreme conditions. The results reveal a significant difference in the performance of the TMD and TLCD for tower vibration suppression under various conditions, with more prominent performance under nonoperational and extreme conditions. In addition, the stroke limitation condition of the TMD has a greater influence on performance. The TMD with a large stroke has the most prominent performance, whereas TLCD effectively mitigates tower vibration under different conditions through small liquid column motion.</div></div>","PeriodicalId":19403,"journal":{"name":"Ocean Engineering","volume":"330 ","pages":"Article 121285"},"PeriodicalIF":4.6,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A complete turbine system was assembled by integrating a customized generator, then tested in the flume to measure start-up velocity and power output. Based on the flume test results, the generator was optimized for higher efficiency before real-seal deployment and evaluation. The results demonstrated the system achieved successful start-up at minimum flow velocities of 0.3 m/s (flume) and 0.26 m/s (sea). Both torque and power output increased with higher flow velocities, and the maximum power coefficient at each flow velocity was achieved at a specific Tip Speed Ratio (TSR) between 0.7 and 0.8. The upgraded generator significantly improved the system's electrical power output efficiency, from 15 % at 0.3 m/s in the flume to 43 % at 0.26 m/s in the sea.
