Need Ice radar when operating in icy waters?

Wouldn’t the new generation navigation radar detect ice?

A Passenger ship is steaming in the Canadian Arctic. It’s springtime, a beautiful day at sea, sun is shining, it’s almost calm. There’s small echo ahead detected by the radars. The echo is bigger on the ice radar. Looking at it with the binoculars you can see a snow covered ice piece. Why is this echo detected earlier and presented better by the ice radar. and not so good by the navigation radar? First – the ice radar on board is an enhanced radar module connected ...

Good article Sten, but of course then you need to integrate that Ice radar into a common visualisation to combine it with satellite imagery, ice charts, metocean data, manual sightings and potential forward looking trajectories. Widgets to estimate and hone) the size weight and draught of the bergs. tools to let you know if your vessel is capable in the forecast conditions (trafficability). And all tied to a global map projection system. So, once you have your radar, come and meet us at Oceanology 2018. (13-15 March @ ExCel) A400.

Thanks Peter. Yes of course, the ice radar should be integrated into the vessels common visualisation. There’s major problem with many bridge systems here - Ice radar is on high definition video. You can of course run it as a layer on your chart radar, as standard definition video, and you will loose surface details displayed on the high def. ice radar. Running on standard definition video you will loose very important details on growlers, a high risk that you will collide with an ice piece. We’ve already seen cruise vessels colliding with growlers, having the ice radar running as a layer on their chart radar running on standard video resolution. This article is the 1st in a series on ice radar. I’m trying to high light the vessel’s benefits with an ice radar. There’s only a very few of the Polar Code Certified vessels having an ice radar on board. You don’t need an ice radar or forward looking sonar to get a Polar Code Certificate, as you know. Another benefit is that the sensors you’ve on board will work also when you’re off line when you’re steaming in Polar Areas. There’s an old say - You need to bring all what you want to use during your stay in Polar Areas. One reason is that you will operate in areas with no satellite coverage. We have seen Cruise Vessels steaming in Baffin Bay, and in Antarctica, without good satellite coverage for many, many hours. I know that a few of them have a good ice radar on board.
