Multi-Year Ice Loads on the Molikpaq: May 12, 1986 Event.
On May 12, 1986, the offshore structure Molikpaq was hit by a large floe containing a mix of thick first-year ice and multi-year ice. The potential impact caused a precautionary evacuation from the structure involving most of the crew. This paper describes that ice loading event in detail. Loads wer...

| Summary: | On May 12, 1986, the offshore structure Molikpaq was hit by a large floe containing a mix of thick first-year ice and multi-year ice. The potential impact caused a precautionary evacuation from the structure involving most of the crew. This paper describes that ice loading event in detail. Loads were measured using three different types of instrumentation – MEDOF panels, strain gauges and extensometers. The calculated loads from all three systems were quite comparable and ranged up to 250 MN on the north face of the structure for this event. NRC publication: Yes |
