Voelker Chief, Advanced Technology Office of Shipbuilding and Marine Technology To: Joseph A. Byrne Director Office of Shipbuilding and Marine Technology During March 12-27, I traveled with representatives of the National Science Foundation (Alexander Sutherland), Raytheon Polar Services Corporation (Paul Olsgaard) and Science and Technology Corporation (James St. John and Aleksandr Iyerusalimskiy) to Finland, Sweden and Germany. The purpose of the trip was to gain insight into the design and operation of their national icebreakers, many of which incorporate innovative concepts. Visits were made to the Finnish Maritime Administration (Markku Mylly) and their icebreaker BOTNICA, the Swedish Maritime Administration (Anders Backman) and their icebreaker ODEN, and the German Alfred Wegener Institute for Polar and Marine Research (Eberhard Fahrbach). Information was also obtained on the new Swedish icebreaker class VIKING and the German polar research vessel POLARSTERN. Attachment A provides some of the notes from our visit while Attachment B contains a discussion on some elements of the technical specification for the new generation research/icebreaker vessel. The trip was very valuable and provided a great start to the feasibility-level design study that MARAD has been contracted to perform for the NSF.

  • Construction of a Hardware-In-The-Loop Simulator for Azipod Control System Testing
    Markus Nylund Construction of a hardware-in-the-loop simulator for Azipod control system testing Thesis submitted for examination for the degree of Master of Science in Technology. Espoo 03.08.2016 Thesis supervisor: Prof. Seppo Ovaska Thesis advisor: D.Sc. (Tech.) Juha Orivuori Aalto-universitetet, PL 11000, 00076 AALTO www.aalto.fi Sammandrag av diplomarbete Författare Markus T. V. Nylund Titel Construction of a hardware-in-the-loop simulator for Azipod control system testing Examensprogram Utbildningsprogrammet för elektronik och elektroteknik Huvud-/biämne Elektronik med tillämpningar Kod S3007 Övervakare Prof. Seppo Ovaska Handledare TkD Juha Orivuori Datum 03.08.2016 Sidantal 9+90 Språk engelska Sammandrag Syftet med detta diplomarbete är att konstruera en simulator för Azipod® roderpropellern. Azipod® är ett varumärke av en roderpropeller med en elmotor som driver propellern. Hela roderenheten är belägen utanför fartygets skrov och det är möjligt att rotera roderpropellern obegränsat runt sin axel. Unikt för roderpropellrar är att drivkraften kan göras fullständigt elektriskt samt att roderpropellern är en dragande propeller till skillnad från tryckande konventionella propellrar. Dessa egenskaper ökar på ett fartygs energieffektivitet. Målet med arbetet är att bygga en (Azipod®) roderpropellersimulator och en tillhörande styrenhet som liknar fartygs styrenheter. Fokus för arbetet ligger på propulsionsstyrenheten. Simulatorn skall fungera liknande som den kommersiella produkten, men med mindre hårdvara. Fartygs styrkonsolpaneler samt alla nödvändiga mätinstrument virtualiseras. Ett extra program skapas för att möjliggöra stimulans för systemet för de virtualiserade mätinstrumenten. Detta program körs från en godtycklig dator som är uppkopplad till simulator nätverket. Simulering av Azipod® roderpropellern utförs av två sammankopplade motorer. Den ena motorn representerar en Azipod® rodermotor och den andra motorn belastar propulsionsmotorn.

  • Problems of Handling Ships Equipped with Azipod Propulsion Systems
    PRACE NAUKOWE POLITECHNIKI WARSZAWSKIEJ z. 95 Transport 2013 Lech Kobyliski Foundation for Safety of Navigation and Environment Protection PROBLEMS OF HANDLING SHIPS EQUIPPED WITH AZIPOD PROPULSION SYSTEMS The manuscript delivered, March 2013 Abstract: Large ships, mainly large cruise vessels, built during last two decades are quite often equipped with revolutionary propulsion devices known under the name AZIPODs. There are many reasons for choosing AZIPODs as main propulsion units, the main reason being excellent manoeuvring characteristics achieved. However in case of large propulsion units, having power of 15-25 MW, used for propulsion there are also some disadvantages and limitations, the last mainly related to operational factors. Handling of ships equipped with AZIPODS is different from handling conventional ships and in certain manoeuvring situations safety of the ship and of the propulsion units might be endangered.. Therefore some limitations imposed on handling procedures are necessary and it is essential that pilots and masters of ships fitted with AZIPODs must be specially trained. Keywords: ship manoeuvrability, podded propulsion, handling of ships with Azipods 1. INTRODUCTION During recent times the new type of vessel has been introduced to the world shipping fleet in large numbers. This type is passenger cruise vessel. Statistics of ships in operation and on order reveals that more than 750 ships of different size that could be defined as cruise ships are recently in operation, more than about 50 of them are large ships of more than 250 metres in length and carrying sometimes as much as 6000 passengers. According to the definition cruise ship is usually a very large passenger ship that makes a roundtrip with several en route stops and takes passengers only at the port where trip begins and ends.

  • The Development of the New Double Acting Ships for Ice Operation
    POAC 2001, OTTAWA 12-17.8.2001 THE DEVELOPMENT OF THE NEW DOUBLE ACTING SHIPS FOR ICE OPERATION Kimmo Juurmaa, Tom Mattsson, Göran Wilkman Kvaerner Masa-Yards Arctic Technology, Helsinki, Finland THE DEVELOPMENT OF THE NEW DOUBLE ACTING SHIPS FOR ICE OPERATION Kimmo Juurmaa, Tom Mattsson, Göran Wilkman Kvaerner Masa-Yards Arctic Technology, Helsinki, Finland ABSTRACT Most of the traditional icebreakers have had good capability to run astern in ice even the vessels are not designed for that. The development during the last 10 years has made it possible that running astern could be considered as the main way of operation in heavy ice conditions. The key to this development is the use of azimuthing podded propulsion, which gives the vessel the benefits of both electric propulsion and excellent maneuverability. These are now combined for the first time. Kvaerner Masa-Yards together with ABB Azipod has developed the concept for more and more demanding projects. Without the participation of ship owners the development could have slowed down, because reality is the final testing ground. The Azipod propulsion has been earlier described in a number of papers. This paper concentrates on the recent development of the Double acting principal including the multy pod applications at the speed range where the Double acting principal is still beneficial. Results from the latest model tests will be discussed. INTRODUCTION Traditionally ice breaking ships have been quite poor in open water. The total efficiency has been 20-40 % less than a good open water vessel. This has been mainly due to the bow forms, which have been developed to break thicker and thicker ice.

  • Electrical Systems in Pod Propulsion
    Electrical systems in pod propulsion Master of Science Thesis of Electric Power Engineering Lena Bergh Ulrika Helldén Department of Energy and Environment Division of Electric Power Engineering CHALMERS UNIVERSITY OF TECHNOLOGY Göteborg, Sweden, 2007 II Abstract Since the middle of the 1990´s pod propulsion in marine applications have become common. There are mainly two manufactures on the pod market. ABB is the biggest producer and has two types of pod-types, Azipod (5-30 MW) and Compact (0.4-5 MW). Rolls-Royce (RR) is the second biggest company on the market, producing a pod called Mermaid (5-25 MW). The electrical system in pod propulsion normally consists of a transformer, a frequency converter and an electric motor. The transformer is used to divide the system into several parts in order to obtain different voltage levels but also for phase shift voltages for the used rectifiers. The purpose of the frequency converter is to control the speed and torque of the motor by changing a constant frequency from the main generator into variable frequency for the motor. The electric motor is used for conversion from electrical to mechanical power for the propeller. Azipod has a synchronous motor controlled by a cyclo converter and dry type transformer. The non-drive end bearing is insulated and the shaft is grounded to earth in drive end and to the bearing housing in non-drive end. Mermaid has a dry type transformer and a synchronous motor controlled by a load commutated inverter (LCI). Both bearings are insulated and the shaft is grounded at the drive-end.
