The Ship Of The Cargo - 1063 Words

The vessel was traveling outside normal shipping lanes in an attempt to avoid ice. Within six hours of the grounding, the Exxon Valdez spilled approximately 10.9 million gallons of its 53 million gallon cargo of Prudhoe Bay crude oil. The article states that the vessel encounter icebergs in the shipping lanes caused the decision of leaving the shipping lanes. However, it is unknown why the orders of returning to the shipping lanes at a certain point where not followed. However, five probable causes have been established for the reasons of the spill. One, the third mate failed to maneuver the vessel correctly, possibly due to fatigue and excessive workload. Second, the master did not provide a proper navigation watch, possibly due to†¦show more content†¦From using, a different method to determine the speed at which the oil spill ran I also found that the oil did not migrate linearly from the spill site in terms of distance as a function of time. I concluded that there was a non-linearity between day 19 and day 38. This non-linearity could be caused by the change in the current movement in the Gulf of Alaska. Part 3-Design and Methodology: For finding how fast, the oil moves down the Gulf of Alaska I first found a quick and imprecise rate of 8.39 miles/day by dividing 470 miles by 56 days. I knew this was not an exact number, but it gave me somewhere to start. I then turn to excel to find a more precise rate. I used the days as my y-axis and the miles the oil migrated as my x-axis. From creating a graph, I was able to find from the regression equation that the oil moves at a rate of 7.69 miles/day. The non-linearity that I found in the data shows that the gap happens between day 19 and day 28. In this gap, I found that the oil spill slowed down to about 1.58 miles/day. I calculated the regression of the first gap from day 4 to day 19 and found that the oil spill moved at a rate of 13.09 miles/day. Then I did the same for the upper half of the break and found that the oil spill runs 10.55 miles/day from day 38 to day 56. Seeing these calculations proved to me the non-linearity of the migration of the oil. Part 4 Results and Findings: From my calculations, I found that the oil movedShow MoreRelatedRecommendation for Tasco Essay761 Words   |  4 Pagesrelationship. Buy a cargo ship that named TASCO.
