Using the experience gained from multi purpose icebreakers operating in the Beaufort Sea as well as from the Swedish icebreaker Oden it is possible to design and construct life boats that will be capable of traversing any first year ice in the ramming mode. Outward sloping frames in the water line all around the ship will guarantee the ship’s ability to survive ice pressure conditions. This paper describes an ice breaking life boat with a displacement of just over 200 tonnes with a propulsion power of about 1 MW with room for 250 people in a high state of safety. Detailed scantlings and weights are presented based on a hull form in its entirety built of flat plates. Design concepts to deal with burning oil on top of the water and icing conditions in a sea state during freezing conditions are presented in some detail.
