  • Maximum 130 persons on board,
  • same amount of crew (44 persons) living in single and double rooms
  • Normal cruises up to 60 scientist
  • Rooms for international reception and political delegations
  • Safety equipment (life boats) on each side 100%
    Seakeeping stabilizer suitable for the transit cruises and station operation
    AviationHelicopter Deck and Hangar for 2-3 Helicopter
    Cargo80 places for 20” Containers (laboratories and storage)
    Cargo science and on and off loading at Neumayer station III:
  • multiple systems like sliding beams
  • A-Frame
  • cranes
  • Hangars with moonpool, and laboratories
  • Winches
  • the “german” traditional open working deck in L-Form at starboard
  • Optimization of the hull shape for
  • ice breaking capabilities
  • efficiencies transit cruises (cruising speed, sea keeping capabilities , energy efficiencies etc.)
  • noise emission and vibration (aim to reach fulfill ICES 209 in open water conditions)
  • bubble sweep down and hydroacustic capabilities
  • Optimization of the shape wind flow atmosphere and air chemistry sciences
    Noise emission compliance to ICES 209 with some modifications
    exhaust emissionCompliance with the exhaust emission limits according to IMO Tier III and beyond (NOx- limits -30% and use of particle filters (reduction of 90 %) The use of LNG was examined, but rejected on the basis of technical conceptual and logistical evaluation
    Other Features
  • Possibility for emergency overwintering in the Antarctic Weddel Sea Gyro
  • Concept of "Safe return to Port", except when stuck in ice
  • Reliability of all systems
  • Improved maneuvering capability and dynamic positioning capabilities
  • Claim to an overall "quiet ship".
  • Demanding energy efficiency and environmental standards, including the “Blauen Engel”
  • High demands on the redundancy levels of the systems
