| 释义 |
ConceptThe E3 project represents three main design criteria: Efficient in operations, Environmental friendly and Economically viable.[3] Smit International is one of the main tugboat users in the Port of Rotterdam and is supplied by Damen Shipyards Gorinchem.[4] ProjectThe project itself is divided into three key stages. The first stage consists studying the highly advanced tug already operating in the port, the Smit Elbe(Damen ASD Tug 2810). The research from the existing tug will provide the necessary data to start of the second stage of the project. The second stage being the design of a new propulsion system for a separate Damen ASD Tug 2810 model tug. This propulsion system must incorporate the latest technology to complete the aforementioned efficiency increases as well as satisfy the three Es. The third stage will be the design of a Damen ASD Tug 2810 of the future using technologies that should be available in about ten years time. First Stage (Testing)The first stage of testing was conducted over a four-week period and in that time 27 tows were performed. The Parameters which were directly affected and measured in this test are:
Also studied were the five operational modes of normal tugboat operation besides the engines shutoff. Below is the operation data summarized.[2]
Second Stage (Design)Working in conjunction with students at the Technological University of Delft multiple design options were simulated and tested. The main goals remained the same, to reduce emissions and increase fuel efficiency. The University created a dynamic model on which the user can choose the components of the vessel to best increase efficiency.[5] Third Stage (Future Design)This design is focused on building a tug using technology which may be available today, but for certain factors such as cost, safety, and miniaturization it would not be feasible today. For instance the use of LNG as a power source has been considered, but is still far too costly to be implemented.[6] References1. ^{{cite journal|author1=Roderique van Erp |author2=Peter Korte kaas |author3=Jules Verlinden |author4=Joost Mathot |author5=Robert Van Koperen |author6=Pepijn de Vries|title=Update of the E3 tug development|journal=Towmasters|year=2010|url=http://towmasters.files.wordpress.com/2010/09/its17_e3_tug_development.pdf|accessdate=23 April 2012}} 2. ^1 2 {{cite news|title=E3 Tug Development: Economically viable, Environmentally friendly, Efficient in operation |url=http://towmasters.files.wordpress.com/2009/06/ecotugdevelopment.pdf |accessdate=20 April 2012|author1=FJ Botke|author2=d B Jansen|author3=LJ Mathôt|author4=RM van Koperen|pages=6}} 3. ^{{cite web|title=The Development of an environmental friendly harbor tug|url=http://www.smit.com/sitefactor/public/News/Maritime_Awards/Factsheet_E3_Tug.pdf|accessdate=21 April 2012}} 4. ^{{cite web|title=DAMEN DEVELOPS EXTRA EFFICIENT ENVIRONMENTALLY FRIENDLY HYBRID TUG (E3 TUG)|url=http://www.damen.nl/innovation/projects/e3-tug-p|publisher=Damen Shipyards Group|accessdate=23 April 2012}} 5. ^{{cite book|title=Diesel exhaust emission control modeling 2006|year=2006|publisher=Society of Automotive Engineers|location=Warrendale, Pa|isbn=0768017580|pages=261}} 6. ^{{cite book|last=Apsley|first=Judith|title=Propulsion Drive Models for Full Electric Marine Propulsion Systems|year=2009|publisher=Institute of Electrical and Electronics Engineers|isbn=0780392590}} External links
