This selection/rejection/ intention report has chosen what I will carry out in my design. The nature of the designs is well organized, ecologically friendly, and safe to users. The angles should look clean and be aesthetically pleasing to the viewer. Also, modern and ecologically friendly materials must be used to add to the pleasing aesthetics. They must provide a viable solution for the organization of the fuel stations to limit boat traffic and to meet the demand of fuel.
The first solution is the largest of the three alternate solutions. It has 4 pumps for 8 slips and two additional pumps for up to 4 additional fueling stations for boats who would like to quickly pull in. The 8 other slips must be used by boaters who are willing to pull or back into the space. In total, there are 6 fueling pumps. A fuel house for the gas attendants that is 20 by 15 feet resides in the middle of the large platform dock. Additional piping goes through to the fuel house such as waste and water and follows the same pipe line as the gas pumps. Each of the slips is 20 feet wide and 50 feet long on 45 degree angles from the side. If chosen as a solution, there would have to be some changes made to the layout due to the new site area which is described in the edited specifications and limitations. Also, I would replace the lined strips of dock with pilings with rope atop of each one to mark the slip’s space and angle.
Pros:
- The design is very large and can provide fuel access to a large amount of boats.
- There are many options for the boats to gain access, even on the busiest of days.
- The design efficiently uses the amount of pumps due to the placement of the Superflow Dual Dispenser pumps in the middle of two slips (1 pump per 2 slips)
- Long fuel hoses can access any type of boat
- Pipelines running centrally down the underside of the dock offer protection for the lines
- The 100 foot fueling spot allows large boats and ferries to have access to
Cons:
- Takes up a large amount of space and materials
- Fuel attendants might have trouble covering large amount of ground
- May have more pumps than needed
The second solution is the second largest, occupying a 90 foot by 90 foot space. In this solution there are 4 slips that boats would be able to back into to fuel up and an additional 70 foot space at the end of the dock for a single, large boat or two small sized boats to pull up and tie up. The two slips on each side will each share a pump with two hoses. The slips are at 45 degree angles and are 20 feet wide and 40 feet long. As in the previous solution, there is a fuel house that lies in the center of the end diamond shaped portion of the dock. It is 15 feet from the end of the dock and its area is 20 feet by 15 feet. The piping for the dock lies underneath it in the center of the dock and extends to each of the pumps. If this were a chosen solution, I would have to adjust the placement of the pumps to make sure they are a safe distance away from the edge of the dock. The gas attendants should not have any problems after that adjustment to travel from pump to pump in a short amount of time. Also, I would replace the lined strips of dock with pilings with rope atop of each one to mark the slip’s space and angle.
Pros:
- The design is fairly large and can provide fuel access to a large amount of boats of all shapes and sizes.
- The design efficiently uses the amount of pumps due to the placement of the Superflow Dual Dispenser pumps in the middle of two slips (1 pump per 2 slips)
- Long fuel hoses that are to be used can access any type of boat
- Pipelines running centrally down the underside of the dock offer protection to the lines
- Fuel attendants will be able to sufficiently access the three different pumps
- The 70 foot fueling spot allows large boats and ferries to have access to fuel
Cons:
- The end diamond shaped dock takes up more space and materials than necessary. The additional angles should be flattened out
- Does not offer the most amount of service opportunities
- There would be boat traffic on busy days with only 5 fueling stations/slips
The third and final solution for the layout of the docks takes up a space that is 100 feet long and 75 feet wide. It is the smallest of the three designs. Unlike the other two designs, this solutions design has smaller slips and has harsher angles that may not be aesthetically pleasing. There are 4 slips in total and they are 18 feet wide and 25 feet long. They can potentially accommodate ships that are longer than 25 feet long, both their bows would stick out into the water causing boat traffic and less protection of the ships. The pumps are located right off of the main dock in the middle of the sets of slips. The gas pumps that jut out from the dock are protected by the triangular barriers. There are two more pumps at the end of the dock on either side. They occupy the spaces that are the 135 degree parts of the trapezoid. The fuel house is in the center of the trapezoid end of the dock. It is 20 feet wide and 12 feet long. The piping runs under the center of the dock n order to have the utmost protection and eliminate spills from boat impact on the pipes. If this were the chosen solution, I would eliminate the triangular extension of dock jutting out between the slips and replace them with pilings. Also, the fueling pumps would have to be adjusted to they do not rest at the edges of the dock, but a few feet in from the edges.
Pros:
- The design efficiently uses the amount of pumps by the slips due to the placement of the Superflow Dual Dispenser pumps in the middle of two slips (1 pump per 2 slips)
- Long fuel hoses that are to be used can access any type of boat
- Pipelines running centrally down the underside of the dock offer protection to the lines
- Fuel attendants will be able to sufficiently access the four different pumps
Cons:
- The design is small and is not able to provide fuel access to a large amount of boats of all shapes and sizes.
- The pumps at the end of the dock would not be efficiently used.
- Does not offer the most amount of service opportunities
- There would be boat traffic on busy days with only 5 fueling stations/slips
- Boats larger than 25 feet in length may have trouble protecting their boats from possible damage

The design that will be chosen according to the Spec Check chart is Solution #1. It adheres to all of the specifications the best out of the three designs. I was most importantly looking to chose a design with the largest possible amount of pumps and areas with access to fuel so that it would always have minimal boat traffic, even on busy summer weekends. The only minor drawback in the fact that it is larger than the other solutions is that it would take up more materials thus being less ecologically efficient. But if it is well maintained and the large size would limit boat crashes and potential oil spills from those crashes, then that is what is more important in the final solution.
The details that will need to be changed in the design are few but very important. The fuel pumps will need to be placed a few more feet from the edge of the dock for two reasons. One, the attendants would be able to have better access to the pumps and the operating systems, and two, the added distance would not allow boats to impact the pumps resulting in spills. I found out from my fellow teammate, MaR, that my dock will be stationary which I was pleased to hear. For my designs, I simply focused on the layout because this could have changed depending on the way she wanted to design the docks. The piping will not have to touch the water and I will familiarize myself with the methods of installing the piping under the dock with the research I have done. Once my other teammate, MiR, knows what he is doing with his pipelines that run under the ground, I will be able to connect to his piping easily.
