Hybrid-electric propulsion technologies offer a solution by interfacing multiple power sources, including batteries, with sophisticated energy management systems. An Agile Power Management System for marine vessels is presented by a Babcock led consortium with the University of Warwick (WMG) and Potenza Technology Ltd. The aim of this Innovate-UK funded project is to take advances in automotive energy management techniques and develop a modular marine power management system, addressing the latest guidance and legislation for marine applications. The system employs novel power management algorithms developed using Hardware-in-the-Loop (HIL) modelling techniques. Capable of interfacing energy storage with multiple power sources and loads, the algorithms seek to maximise overall efficiency by improving prime-mover operational envelopes, hence reducing emissions and fuel consumption.","PeriodicalId":313785,"journal":{"name":"Power & Propulsion Alternatives for Ships 2019","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116492201","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}

Paakkari","doi":"10.3940/RINA.PPA.2019.11","DOIUrl":"https://doi.org/10.3940/RINA.PPA.2019.11","url":null,"abstract":"With an increasing need to reduce the emissions related to global shipping, means of emission free propulsion are required. Use of auxiliary wind propulsion is a natural choice as wind is free, globally available, and it is provided “on-site” instead of having to be transported with the ship from the port. Norsepower has modernised the Flettner rotor concept to obtain a highly efficient and robust solution to utilize the propulsive potential of the wind. Norsepower Rotor Sails harness the wind to provide a clean source of propulsion for various ship types. This paper addresses the need and means to provide the shipping market with verified information on the obtained savings with Rotor Sails. The paper also reviews the experiences of recent installations and finally provides an outlook of the global wind propulsion potential with respect to the busiest shipping routes.","PeriodicalId":313785,"journal":{"name":"Power & Propulsion Alternatives for Ships 2019","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132694205","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}
