Single pod could have been an alternate choice from manufacturers. Of course twin propellers have an advatage of using smaller diamter thus creating more hull aperture.<br><br>How will the vessel be dealing with drifting ice while drilling? Does it mean that the vessel still requires ice management by suitably deploed other ice breakers.Arun Kr.

Please confirm.Arun Kr. DevFri, 08 Feb 2008 10:14:04 -0000
