Kronprins Haakon Scientific Icebreaker

An icebreaker is NOT an optimal platform for hydroacoustic systems!

The Beauty & The Beast

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 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.

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.
