The study examines changes in sea ice and ocean conditions in the Arctic with their implications for off-shore safety. The objective of the research is to develop a basis for forecasting technologies for maritime operations.We assess loads on off-shore structures from sea ice and ocean in centennial climate future projections and implications for the accessibility and future Arctic shipping. As a test case, we calculate loads on a tubular structure of 100-m wide and 20-m tall, similar to installations in the Beaufort Sea in the 1980s. With sea ice retreating, loads are predicted to increase from ~0.1 106 N (MN) at present to ~50–200 MN in the 2090s, primarily due to wave loads. This study asserts the need for new approaches in forecasting to make marine operations in the Arctic safer.
