Through short-term forecasting and long-term forecasting, the wave bending moment and wave force of each cross section of the LNG ship, as well as the motion response of LNG ship which have the greatest influence on the wave load are obtained. Based on this, the wave force and motion response is performed, and the mooring point is set according to the actual environmental conditions when the LNG ship is moored at the dock. The mooring force of each cable that meets the specifications and the number of mooring lines required are finally obtained. The research results in this paper can provide a technical support for dock mooring setup and mooring force calculation for similar ship types.","PeriodicalId":30229,"journal":{"name":"Journal of Defense Resources Management","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87319972","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}

It requires multi-sectoral collaboration between law enforcement, public and animal health and in severe cases civil-military collaboration. By building a collaborative management culture between these sectors, through joint education, training and exercise activities, better methods and tools will be obtained in order to reach interoperability and an integrated preparedness approach. Lessons learned and experiences from previous projects, courses, workshops, and simulation exercises require a rationale knowledge transfer. Horison scanning is one example of a method that can be recommended to educate strategic analysts jointly from various sectors and the “Decision Theater” is a dynamic and flexible tool that is useful to train decision makers to examine complex bio-agro defense and biosecurity problems.","PeriodicalId":30229,"journal":{"name":"Journal of Defense Resources Management","volume":"5 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2015-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-0374.1000131","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70799168","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}
{"title":"Considerations on United States Navy Infrastructure Readiness","authors":"Travis J Summers","doi":"10.35248/2167-0374.19.9.181","DOIUrl":"https://doi.org/10.35248/2167-0374.19.9.181","url":null,"abstract":"The purpose of this qualitative grounded theory study was to examine the definition of infrastructure readiness in terms of Navy laboratories, and to define the best criteria or approach for effectively managing readiness to meet changing technical mission requirements. Through semi structured interviews with leadership about their perceived definition of infrastructure readiness and perceived adequacy of the current model, clarity emerged on the criteria for adequately defining, measuring, and assessing Navy laboratory infrastructure readiness. This will allow further evaluation of the existing system and identification of any gaps or risks. The primary goal of this study was to create an accurate definition of Navy laboratory infrastructure readiness, and subsequently, the key attributes to that readiness. The second goal of the study was to research other readiness systems to assess their readiness elements, and measures to determine the applicability to Navy laboratories and the feasibility of adaption of their systems for Navy laboratory use. The third and the final goal of the study was to further research on how to utilize existing models and systems in other areas to apply to any gaps identified through the interview process of the qualitative study. The study found that infrastructure readiness is viewed holistically as an environment to perform work, and includes items outside the technical definition of infrastructure, to include items like space, laboratory equipment, and processes, and that there are significant gaps in the existing Navy infrastructure readiness systems to manage many of these areas. In addition, two management system approaches emerged, tactical and strategic. Tactical management is focused on real-time management of systems to ensure a readiness state, while strategic management is more of a capacity management system to ensure adequate capacity when needed.","PeriodicalId":30229,"journal":{"name":"Journal of Defense Resources Management","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81397545","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}
