Evaluation of the Strength and Seakeeping Ability of Pollution Control Barriers

摘要

The purpose of the work described by the report is to provide a basis for the evaluation of arbitrary oil pollution control barriers without the need for full scale testing. It is described that for well designed barriers the principal cause of oil leakage is droplet entrainment which has little, if anything, to do with the barrier, but rather depends on how the barrier is used. Since the leakage from droplet entrainment cannot be quantitatively predicted at this time and is only slightly dependent on barrier design, a barrier is best evaluated on its strength and seakeeping ability. A barrier is adequate for the task intended if it is strong enough and follows the seas well enough for it to provide a surface-piercing curtain with adaquate draft and freeboard. The report gives means for making these evaluations. These are substantiated with full scale, model and analytical results.
