CONSTRUCTION ASPECTS OF BUILDING AN EVACUATION ROUTE THROUGH RUBBLE SURROUNDING BEAUFORT SEA STRUCTURES

摘要

For EER plans involving on-ice evacuation methods in the winter, an emergency shelter located on the adjacent ice is an important safety element for personnel working in oil or gas facilities in the Beaufort Sea. The ice surrounding a structure can vary from thin level first year ice to grounded rubble or ridges. The speed and safety of walking over the ice surface is strongly affected by the surface roughness and degree of ice rubble. Thus, a groomed trail from an oil or gas structure to an emergency shelter should be constructed that is suitable for walking. This paper discusses the methods, equipment required, construction duration and associated risks to efficiently construct and maintain the trail. The emphasis is on practical methods that can work in the wide range of ice and weather conditions that can occur in the Beaufort Sea region during the winter and spring.
