The report identifies present and future marine traffic and related characteristics of vessels using Unimak Pass. Present and future vessel traffic estimates through the year 2000 are developed for four categories: fishing; natural resources; commercial shipping; and Outer Continental Shelf (OCS) activities. Total annual vessel traffic for the year 2000 is estimated to increase approximately 100 percent over the base year from approximately 2290 trips to 4600 trips in 2000. The report assesses the impact, i.e., increase in collisions, of additional vessel traffic using Unimak Pass as a result of future OCS activities in northern and western Alaska. The OCS traffic almost doubles the likelihood of a collision in the pass by the year 2000. The collision rate in the Pass without OCS activity is estimated at one collision every 57 years, while the collision rate with OCS activity is estimated at one collision every 33 years in the year 2000.
