3 An icebreaker is NOT an optimal platform for hydroacoustic systems! Main challenges: The bow shape is far from optimal to avoid bubble sweep down Heavy machinery might create vibrations adversely influencing the acoustic systems Blister or Gondola can not be used The Beauty & The Beast

4 The benefit of the bow design of FF Kronprins Haakon: The knife will push aerated water to the sides of the box keel The box keel gives additional draft to the vessel. Deeper is better! The box keel houses a number of acoustic systems that can be used while sailing in ice conditions.

9 Kronprins Haakon Scientific Icebreaker Systems installed in the drop keels: MS70 - Side looking multibeam sonar ME70 - Downward-looking multibeam sonar EK80 - With six frequencies ITI - Two hydrophones EM710-1 x 1 multibeam echosounder MRU5 - In subsea bottle Subsea cameras - One in each drop keel, forward looking 3 rd party equipment: ADCP 38 khz - With acoustic window ADCP 150 khz - With acoustic window SV probe - Mounted in tank inside dk

10 What to focus on when planning a scientific vessel? The shape of the bow design of the vessel, to avoid bubble sweep down Use retractable azimuth thruster(s) with a bottom plate flush with the ships hull to avoid aeration from tunnel thrusters. Make a Gondola to house all large transducers (not valid for ice breakers). Use drop keels for scientific echosounders and other sensitive acoustic systems. Install hydrophones for trawl instrumentation, hydrophones for noise measurement and cameras in the drop keels. Design the vessel according to DNV Silent R or similar. Avoid any sharp edges on the hull forward of the transducer installations Dimensional survey of the transducers, MRU s and the antennas is very important Keep focus on EMC Install the transceivers as close to the transducers as possible. Install the computers in a separate room, not in the operation central. This is to avoid noise and heat in operation room. Use a KVM matrix system to limit number of monitors and ease the operation of the systems installed High quality steel work is important for the transducer installation.

13 Computers and monitors in the wheelhouse are integrated in the bridge and overhead consoles Computers and KVM matrix system installed in IT room Signal distribution box installed in IT room KVM matrix system design made by Jan Bremnes (IMR). The KVM matrix is connected to the vessel infotainment system. Very clever solution! / 13 / 30-Sep-16 KONGSBERG PROPRIETARY See Statement of Proprietary Information
