In the model test, pontoons behind the rotor model, which is for the buoyancy of a truss-platform, were applied, and the different motion characteristics of the rotor model were investigated in accordance with existence and nonexistence of the pontoons. The experiments were performed in three different wave heights, and the experimental results were directly compared with frequency domain analysis results. From the model test, it could be found that the pontoons move the resonance period of the rotor, and the pitch motions of the rotor in the case of the relatively high wave height were largely varied in low wave periods compared to the resonance period of the rotor. Also, independently of the pontoons, the resonance periods of the rotor in three wave heights were moved to low wave period direction independently of the pontoons as the wave height rose. And the normalized pitch motions of the rotor by three wave heights decreased as the wave height rose.","PeriodicalId":143096,"journal":{"name":"Journal of the Korean Society for Marine Environment & Energy","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115615672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The consequence of damages and impacts from the developmental projects such as public waters reclamation and marine sand mining tend to emerge in the fish farms and fishery resources mainly, but in-situ survey and impact assessment related to these items were insufficient compared to other items such as physical, chemical, pelagic and benthic ecosystem factors. In case of fish, fish egg and larvae, not only the information of basic current situation was insufficient, but also the survey time, sampling and control site, as well as methods were inappropriate. In addition, the predictions and reduction measures after construction were very limited, and postmonitoring for actual verification was unreasonable. In order to improve these problems of marine environmental impact assessment and induce a reasonable assessment in the future, improvement of the statement regulations and establishment of information system related to field data based on fishery resources are necessary.","PeriodicalId":143096,"journal":{"name":"Journal of the Korean Society for Marine Environment & Energy","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129208619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
