About the event:
More robust ships with stronger hulls are needed for polar navigation to overcome the extra resistance that sea ice presents and to endure the effects of the numerous ice encounters that may emerge.
An ice-class ship needs more power to overcome the resistance when travelling through ice-infested seas because of its increased strength and the additional weight of its structure. Ice-going vessels typically require additional power compared to a regular vessel of comparable size that results in increased emissions of pollutants into the atmosphere, higher original shipbuilding costs, and higher operating expenses.
This presentation looks at one vessel in detail, RNZN Aotearoa, design to Polar Class PC6 (Summer/autumn operation in medium first-year ice which may include old ice inclusions with an ice thickness from 70 to 120 cm (2.3 to 3.9 ft). It will also look at several of the technologies onboard to adapt to this requirement, the hull design and survival equipment. There will also be a look at the Polar Code and how it affects ship safety, as well as details with the certification.
