Although each technology can have very specific applications, when it is wanted to apply to Computer Aided Design, Manufacturing\u0000& Engineering (CAD/CAM/CAE) System, they have to be implemented as a whole.\u0000The first CAD tools were developed during the middle part of the 20th century, and since then they are in the beginning of the design, but it manages many data that must be taken in advance for the further stages of the lifecycle of the product. Augmented Reality, Virtual Reality and Mixed Reality are closely related to the Digital Twin and interlaced with the Big Data, which are generated by CAD tools and all surrounding solutions, which applies some cloud/edge/fog computing to these data in a merged technology between finite state machines and Artificial Intelligence (AI) cognitive processes. To perform in an agile manner all these integrations requires a network which support different connection ways to add specific devices, i.e. Internet of Things (IoT), which can access to the data, creating and modifying them, in a different \u0000layer which affects to the basic information layer created by the CAD System in the shipyard. This network should be secured but at the same time open to allow distributed work, which must be tracked in such a way that records any modification of every working step done in an open, transparent, trusted and non-modifiable working \u0000method for all stakeholders involved in process, like: shipyard, engineering offices, classification society and ship owner. Results of the design should be easy integrated with future building ways like 3D printing, generating printing orders directly from the CAD model. All the above technologies are reviewed in this paper, as well as revisit the application of them in every shipbuilding phase, from design to manufacturing. An integrated Industry 4.0 CAD system should also be involved in operation and maintenance phases, i.e. it must cover all the vessel lifecycle end to end, from design to decommission.","PeriodicalId":243408,"journal":{"name":"Maritime Innovation and Emerging Technologies 2021","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121244213","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}

IoS presents several challenges, an example of which is the imputation of missing values. A data assessment imputation framework that is utilised to assess the accuracy of any imputation model is presented. To complement this study, a real-time imputation tool is proposed based on an open-source stack. A case study on a total of 4 machinery systems parameters obtained from sensors installed on a cargo vessel is presented to highlight the implementation of this framework. The multivariate imputation technique is performed by applying Kernel Ridge Regression (KRR). As the explanatory variables may also contain missing values, GA-ARIMA is utilised as the \u0000univariate imputation technique. The case study results demonstrate the applicability of the suggested framework in the case of marine machinery systems.","PeriodicalId":243408,"journal":{"name":"Maritime Innovation and Emerging Technologies 2021","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132241191","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}

Due to its ability to make high strength, tough, fatigue resistant welds with very low distortion, and the fact that the process can work underwater, considerable \u0000interest has been shown over many years in transferring the technology to the welding of steel. The difficulties in developing tools able to stir steel at the elevated temperatures required, in excess of 900oC, are now being overcome and the process is being developed for welding steel with an initial focus on marine applications. This paper discusses the \u0000technical advances being made at TWI and outlines the newly begun EU project “RESURGAM” which looks to develop the process for both the construction and repair of ships.","PeriodicalId":243408,"journal":{"name":"Maritime Innovation and Emerging Technologies 2021","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130027825","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}

Future floating wind farms enable the access to significant new wind resources in expanses of water too deep for conventional, bottom-fixed farms. Spar, barge, TLP and semisubmersible types have been deployed as demonstration units. Pre commercial units have been installed off the coasts of Portugal and the East Coast of Scotland. \u0000\u0000This paper discusses naval architecture requirements for the temporary conditions of construction, ocean transport and installation. The requirements of Marine Warranty Surveyor guidelines for temporary conditions and the Classification Society requirements during the temporary phase are also taken into account. It is expected that major offshore maintenance will be carried out on floating offshore wind turbines by towing them back to more sheltered port locations. This paper is a literature and guideline review with additional information on intact stability during the tow to the \u0000offshore location. Thus, marine operations play a pivotal role throughout all phases of a floating wind farm’s life cycle. In particular, uncertainties associated with offshore installation work can extend construction schedules and increase the capital expenditure required for the project. This paper will be of interest to researchers and practitioners in the floating wind sector, considering innovative installation methods as a means to reduce overall project lifecycle cost.","PeriodicalId":243408,"journal":{"name":"Maritime Innovation and Emerging Technologies 2021","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128573480","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 fuels, selected as zero net greenhouse gas emissions across their lifecycle, would allow the yacht to comply to the newest IMO targets but would certainly imply some changes and modification to the design. These modifications are analysed under different aspects and in relation to different parameter, in order to have a clear and objective analysis; the effects of the Class rules are also evaluated where possible and applicable. The conclusions presented leave some questions still open as there are no unique solutions that the designer could take but the pros and cons of the different solutions are presented and the constraints that they impose on the new designs clearly identified.","PeriodicalId":243408,"journal":{"name":"Maritime Innovation and Emerging Technologies 2021","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126993260","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}

CFD simulation is also carried out for surface condition by FINEMarine and pressure distribution on the hull is appeared. Towing mechanism should be arranged into account in order to fix the pitch motion and to measure hydrodynamic forces. This paper briefs about the towing method and result between model test and CFD.

As new technology reduces in cost, opportunities arise in the maritime sector. This research strives to make objects that may be hazardous for navigation more easily seen in poor visibility. The wider study aims to allow the crew to see holograms of the navigation-lights of other vessels and chart-objects when they would be otherwise obscured by fog. This needs the bringing together of a variety of real-time data from bridge equipment. Each device has a different protocol/dated format, that in some cases may present conflicting information. The research presented here addresses the problem of reviewing data sources, categorising data types/strings, and converting them into a common language; to define/locate the holograms. The collected information is processed using bespoke algorithms. The outcomes present the selected methodologies and derived solutions for the holographic navigational enhancements.","PeriodicalId":243408,"journal":{"name":"Maritime Innovation and Emerging Technologies 2021","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115091258","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}
