The MT Tempera is an ocean-going icebreaking tanker that was finished in 2002.
Using Azipod technology, the MT Tempera and its sister ship the MT Mastera are known as double acting tankers. Azipods or Azimuthing Podded Propulsors have an electrically driven propeller mounted on a steerable pod. With the propellor usually facing forward, similar to an airplane, the propellor is much more efficient. In addition, the pod can apply its force in any direction. Azipods allow ships to be more maneuverable and able to travel backward as easily as it travels forward.
While icebreaking tankers are not new, all icebreaking ships have to compromise their open water performance. The shape that allows icebreakers to break ice is not fuel efficient or handle well in waves. Most cargo vessels will avoid navigating through ice when possible, the MT Tempera and Mastera are no different. These double acting vessels have compromised and travel forward using a conventional bulbed bow in open water for maximum efficiency. In ice conditions these vessels navigate backwards using their stern which is shaped like an icebreakers bow.
Built in Japan by Sumitomo Heavy Industries at the Yokosuka Ship Yards. The vessels are in use by the Fortum Shipping Company in Finland.
