Pipeline Proposal

 

Problem:  Assume you are a group of environmental engineers who have been hired by the Ohio Department of Geographical Ecology.  Your assignment is to determine at least four different proposals for pipeline routes connecting various wells in an oil fertile area.  The attached map is a section of a U.S. Geographical Survey Contour Map of northeast Ohio with wetland (swamp) area outlined for clarity. 

 

Given Information:

  1. An existing oil well is located approximately at point B.
  2. A new well is to be dug at point A and your pipeline installation company must determine where to lay the connecting pipe.
  3. Both well sites are adjacent to the wetlands.
  4. All routes must consist of straight two-inch pipe (No curves).
  5. Straight two-inch coated pipe must be used at a cost of $1.50/foot.
  6. A maximum of two elbow joints may be used.  Assume that the elbow joints may be fabricated with any angle measure and the cost is included in the pipe cost.
  7. In crossing normal terrain, installation cost is $1.20/foot.
  8. Installation in the wetland area requires an additional Track Hoe at a cost of $60/hour.
  9. In a 10-hour day, a Track Hoe can dig approximately 300 feet of trench.
  10. The first 700 feet due North of oil well B is adjacent to the wetlands.  This means that as soon as your pipe goes in an eastward direction it is in the wetlands.

 

Suggestions:  One of your proposals cannot cut through any wetland area at all.  It must completely go around it.  A second proposal must use the least amount of pipe possible.    The third proposal must go through both dry and wetland areas. Finally a fourth proposal must be the most cost efficient. It could be one of your first three proposals.  All of the proposals must address cost effectiveness and environmental concerns.
