ICEBERG GROUNDING PROBLEMS IN THE NORTH ATLANTIC
Not only the floating bergs, but the grounding and bottom dragging bergs pose a threat of possible damage to pipelines and other installations contained in the sea bed. The type of information on icebergs, required by the petroleum industry needs more intensive work, covering the entire exploration area along Canada's Eastern Seaboard. This paper outlines some aspects of grounding icebergs. Field data on grounding or grounded bergs is hard to come by and what little published data is available is confined to scour marks with no correlation to the icebergs causing them. To obtain an understanding of the grounding phenomena, a simple analytical model was proposed in 1972. From this model, it would be possible to estimate the maximum gouge size in any location from a knowledge of the berg size and the type of ocean sediment at that place. Laboratory tests were conducted to determine the validity of the assumptions made in the analytical model. Some of the results are reported.
