PATRICK DUNBAR
Mechanical Engineer
Welcome to my portfolio!
This page summarizes some of my projects over my career. I have had some amazing projects to show case my engineering and design abilities.
Natrium plant in WV. this is the origination of the 50 mile long G150 pipeline supplying batches of Propane and Butane to the Sunoco MEII pipeline project at the Follansbee, WV site.
The Conley Site is named after the owner Mr. Conley. This is 48.08 miles into the G150 pipeline from Natrium. The Site is located adjacent to the Sunoco property where the batched products from delivered from Natrium are injected into the Sunoco MEII pipeline.

Nov. 2015 - Sept. 2016
I was the Project Engineer/Manager for a mid sized pipeline custody transfer facility project being installed near Follansbee, WV for most of a year. The facility ties an existing 50 mile long pipeline into a new 20 inch diameter pipeline stretching several hundred miles across West Virginia, Ohio, and Pennsylvania. The latest design is for 3000 BPH delivery into the customer 20 inch pipeline on a 72 hour cycle, batching Butane and Propane once per cycle.
My responsibilities included developing the Pre-Feed engineering study and project estimates for the Feed, and 30% design, along with the written proposals, schedules and engineering deliverables, and scope of work documentation. I built the resource loaded engineering estimate along with a details estimate for the total project scope. Also, with these management responsibilities, I managed the Mechanical engineering deliverables, a piping designer, and a Civil Engineer and designer to finalize equipment setbacks and layouts, PFD’s, P&ID’s, issued long lead MR’s for Injection pumps and an Issued for Consecution Civil drawing package.

Crude oil Sample Building.
July - Dec. 2014
A Sample Building is used to determine the quality and exact volume of a customer batch of crude oil being delivered into a tank farm terminal. This Sample Building is located in Superior WI terminal and will be used on a single product pipeline. A sample building is an integrall part of the custody transfer system (cash register).
The general layout of the Sample Building system consists of a Static Mixer and a vendor furnished Sample Building skid package. Within the Sample Building, the system layout starts with an auto sampler and sample can collection weigh scale system, a manual sampling station, and an insulated fast loop with a densitometer, Coriolis meter and provisions for a future viscometer.
I served as the primary Design Engineer for this detailed design.

Mar. 2014 - Feb. 2015
The Superior, WI pipeline terminal project was my primary focus, although the project covered multiple sites along a 600 plus mile pipeline. Our team completed the required engineering calculations and evaluations, applied constructability concepts, and sufficiently document the mechanical work at the facilities on the NPS 24 and 30 diameter portion of the pipeline, from North Dakoda to Wisconsin.
I was involved in the last year of development for this multiyear project. I primarily worded with designers coordinating drawings and redlines for the 60%, 90%, Issued for Bid, and Issued for construction packages. Also, I preformed hydraulic calculations, built material requisitions, technical bid evaluations, and engineered detailed custody transfer systems.

Field Experience.
Jan. 2009 - Mar. 2009
One of my functions while onsite in Burj Dubai, United Arab Emirates, was to investigate and engineer fixes for unforeseen issues. Many of these issues provided me with hands on exposure to design outside of my primary functions as a product engineer. Redesigning facility systems in the field is an example of my ingenuity and ability to adapt.
I spent 2-1/2 years as a team leader managing three engineers and one product designer. Meanwhile, engineering, testing and overseeing production of 10 products currently installed and in operation. Many of these products are located in the world’s largest man made water feature, located in Dubai. This water feature is 5 times larger than the fountains of Bellagio in Las Vegas, NV.
My first project at WET was to produce a more ergonomic and more robust MicroShoter(TM) for the Americana at Brand water feature in Glendale California.

Additional WET Design Experience.
July. 2007 - Jan. 2010
Primarily, was assigned to the "shooter" technology at WET. I was in charge of material selection, mechanical design and testing of new and improved "shooters" for several projects. Additionally, I designed NEMA 50 double door electrical enclosures, submersible color changing HID lights, Wave pool machines, and many supporting devices for the Oarsman(TM), Shooters(TM), and submersible lighting.
Lean Manufacturing principles and continuous improvement design was implemented for all of our product development and manufacturing. As WET grew 400%, I helped develop various department drawing standards, forms and procedures. My team was considered the "A" team by the CEO during the rapid growth of the company, and was used as a model to manage similar teams.

PDC for a Denver Municipal complex. This building is constructed from galvanized cold roll steel and powder coated to the customers color specifications. This PDC houses 6 battery racks, 2 UPS units, and a Purafil air filtration unit. One of the design challenges was to maintain a positive pressure while filtering the air and exhausting any accumulated hydrogen gas during charging.

These pictures represents a low voltage switchgear feeder lineup installed in Golden, Colorado. It is an example of one of five test labs in a low voltage 1600 Ampere DC lineup. This switchgear supplies and switches power to and from test labs for an energy research facility. I was the principle Mechanical engineer on this lineup while providing assistance to the team for 7 similar sets of gear over 8 months. The following pictures depict some of the internal buss in the above lineup.
My primary function at ESS Metron was the mechanical design and engineering for low and medium voltage switch gear. In addition to designing gear, I often was tasked with programing the Trumpf punch press for production of sheet metal for switch gear and PDC's. I saw each of my projects from start to finish. Starting with the customer submittal to QC of the final production unit on the shop floor.
I was the sole Mechanical engineer on a medium volume production run for a server room rack mounted power strip.

November. 2010 - July. 2011
These picture depict a custom designed ITI power distribution product designed for a large search engine company. These units interface with and provide power to custom made server racks. The product is currently being assembled at a rate of 12 units per hour on a LEAN manufacturing assembly line. The power strip was developed, tested and UL Listed over the course of 8 months by myself and an Electrical Engineer. The power strip had to pass heat rise testing at 40 Degrees Celsius under full 32 Ampere load, vibration testing for shipping, H.A.L.T testing to determine life expectancy and warranty life, and short circuit testing at 100KIAC. The following pictures show some of the inner wiring, QC inspection drawings, and one of the three fuse doors.
This project was a challenge on many levels. The schedule and testing requirements along with the UL listing made the project engaging and a learning experience that many junior engineers would long for.
