| Résumé | This paper presents an assessment of the viability of locating evacuation shelters on landfast ice or rubble fields surrounding offshore structures in the Beaufort Sea. For platforms surrounded by stable landfast ice and/or rubble, on-ice evacuation to an evacuation shelter (ES) may be identified as part of an EER plan during the Beaufort Sea�s winter season. There are a number of factors that must be recognized when considering the deployment of an ES on the ice cover around Beaufort Sea structures; for example, the stability and morphology of the ice, the location and number of routes to shelters on the ice and limitations caused of the nature of the emergency. Additionally, issues surrounding personnel access off of a platform and egress to the ES must be examined, along with key concerns about the viability of using an ES soon after freeze-up and during break-up. This paper provides some representative examples of full scale data to illustrate key points about the viability of on-ice ES deployments in winter, on a scenario basis, as a function of water depth. The information that is presented here was assembled through a combination of field experience, literature reviews, and discussions with operating personnel who are directly involved with this type of problem area. |
