This pilot LH 2 C, the Suiso Frontier , debuted in 2021 to demonstrate a series of operational stages ranging from the initial cooling down/loading/unloading of LH 2 to sea-going operations using a newly built pilot LH 2 terminal in Kobe, Japan. The ﬁrst international sea-going voyage by the Suiso Frontier between Japan and Australia was accomplished at the start of 2022. This study intends to describe brieﬂy the ship design focusing on an overview of safety design and risk assessment results, and to provide an update on the demonstration progress describing the operational phase conducted as a series of demonstration tests highlighting the extended gas trial program conducted in Japan and the data-gathering exercise for the Suiso Frontier .","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135889852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, the surface target track uses the geodetic coordinate and under-water weapon trajectory uses the navigation coordinate. Therefore, trajectory data in the navigation coordinate need to be converted to the geodetic coordinate. Using an inertial measurement unit can only get the trajectory data in the navigation coordinate. Because of the Doppler effect, acoustic reverberation, range ambiguity, and low data refresh rate, the methods based on the cooperative acoustic beacon or the baseline positioning cannot meet the trajectory measurement requirements of the underwater high-speed attack weapon. In this paper, a method combining baseline positioning with an inertial measurement unit is proposed to solve the problem of trajectory measurement in the geodetic coordinate of the underwater high-speed weapons. The system composition, working principle, and measure results are introduced, and the measure errors are analyzed.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal is to assess the capabilities and performances of the solver to simulate the propagation of regular waves over the variable bathymetry (in-cluding shoaling and nonlinear e ff ects), the depth-induced breaking process and the interaction of these breaking waves with the vertical wall. We simulate two experiments involving similar geometry of the seabed and vertical wall, performed at two di ff erent scales (1:8 for case A and 1:1 for case B), as described in Ravindar et al. (2021). After a descrip-tion of the CFD solver and its numerical methods, the model is applied to the simulation of the two cases involving extremely high impact pressure peaks at some places of the wall surface. Numerical results are compared with experimental measurements regarding both free surface elevation and pressure on the wall. In general, a good agreement of the simulations with the measurements is obtained for free surface elevation, including the breaking zone. The time history of pressure variations dur-ing wave impacts is correctly reproduced. Although the measured maximum impact pressure peaks exhibit some variability among successive wave impacts, the order of magnitude of these maximum peaks is well predicted for case A. For case B, however, the maximum impact pressures are somewhat underestimated by the current simulations, requiring further tests and improvements. This work is a contribution to the bench-mark “Comparative Study on Breaking Waves Interactions with Vertical Wall attached with Recurved Parapet in Small and Large Scale” set up for the ISOPE’2022 conference.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49523503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
