Background

The Ford Motor Company has a long history of quality and innovation. It’s fitting they’ve become the first automaker to mass-produce a truck with an all-aluminum body. More specifically, a high-strength, military-grade aluminum alloy body that is joined to an all-new high-strength steel frame – making the truck 700 lbs lighter than its predecessor while adding strength, efficiency and improved performance.

Because no one has ever created a high-volume truck with an all-aluminum body, Ford had to develop all-new processes, technologies and standards, and make several upgrades at their Ford Dearborn plant, to ensure success. This included having to perfect heat treating and hydroforming techniques that were necessary to create the aluminum body. Additionally, Ford invented proprietary weld techniques which proved worthy of being used in the production of the world’s best-selling truck. Of course, welding creates heat – especially at this scale – which is where Fluid Cooling Systems (FCS) comes in. The weld tips need constant cooling in order to maintain continuous operation and FCS was tasked with engineering a complete custom process cooling system. This included equipment, pipe sizing, routing instrumentation, the control scheme and a few extras. FCS has been a trusted Ford supplier for several years and was honored to be part of such a historic milestone.

The Challenge

For FCS, any project worth taking on is going to be challenging, which is why it’s so rewarding to design and build a solution and go through a successful start-up. The main challenges related to this project were…

Global Processes and Timing

Part of the reason Ford is known for high-quality is their stringent global processes that guide everything they do. This of course includes plant design, build and operation. The FCS team is familiar with these processes but they require due diligence and the utmost attention just the same. With this project, timing was tight and became a factor because of the additional documentation, inspections and logistical measures Ford required. Time is never on your side when presented with additional requirements.

A Moving Target

The need to design a custom system compatible with Ford’s new technology and processes, which were being modified on their side, created a moving target at times. As the FCS engineers were dialing in their solution, they occasionally had to alter their course to accommodate modified requirements from Ford. There were a lot of variables to consider as the FCS engineers were focused on getting it just right on their side prior to handing off to the FCS production team.

Free Cooling

In addition to having to engineer a first-of-its kind cooling system for Ford’s first-of-its-kind welding processes, the FCS engineers were tasked with providing free cooling. Maintenance and operations costs are significant at a facility of this size so it’s important to create process efficiencies whenever possible.

Approach and Execution

The first step in any successful project is to create a detailed schedule with all key milestones identified. The next step is to share it with all stakeholders to ensure everyone is on board with timing requirements

Once timing and expectations were solidified, the FCS team focused on providing the best, most complete solution for Ford. They made a couple of site visits to meet with Ford engineers, take measurements and work through updated requirements before and during the design stage. Communication was key. As changes occurred, the FCS team was able to adapt quickly and make any necessary design updates before they impacted the schedule.

The onsite measurements were vitally important not only to ensure piping dimensions and fit in the final footprint, but also to ensure there would be sufficient space in the rigging path from the truck to the final destination. In this case, the system design was broken into three skids to accommodate transporting requirements. Harting wire connectors were used for testing in shop prior to shipment and for easy assembly in the plant. This helped the production and installation teams save time and ensure proper wiring connections were made between the three skids.

FCS’s drawings were provided to Ford engineers and incorporated into their CAD program so they could verify system integration prior to build out. This smart step in the process saved planning and engineering time and helped to avoid any costly oversights by either team. FCS also provided a controls matrix to Ford so their maintenance staff would be familiar with all of the functions and alarms in the control panels.

The system was designed to a high standard to guarantee Ford the maximum amount of operations time. FCS included a backup plate and frame heat exchanger as well as backups for all pumps, providing 100% redundancy and allowing this equipment to be cycled on and off to reduce wear. This allows for preventative maintenance without shutting down the system. Additionally, the pipe diameter was sized based on water velocity to reduce the likelihood of pipe and component erosion. This also helped reduce the noise generated by the system’s fluid flow to help keep ambient noise levels down.

Free cooling was one of the main requirements on this project. It was accomplished by designing the heat exchanger to be used with either the chiller or cooling tower. During cooler months, the chiller can be shut down with the chilled water loop isolated, which allows the use of cold water provided through a closed circuit evaporative cooler. Colder seasonal temperatures chill the process water at a fraction of the cost of running a chiller. Ford maintenance staff can run through the chiller’s routine maintenance during the free cooling mode without shutting down production or compromising the quality of chilled water being sent to the process – all while saving energy and reducing the carbon footprint.

The Outcome

Because of their due diligence up front, constant communication and familiarity with Ford’s global requirements, FCS delivered everything on time and within budget. There were no surprises and no change-orders

Because free cooling was utilized, Ford can expect to save 88kw/hr when the system is operating in the free cooling mode. Based on planned operating schedules, this custom cooling system will pay for itself in approximately five years.

Ford ended up with an innovative industrial design that’s efficient and scalable for future expansion, and will be applied to other facilities in the near future.

Lastly, Fluid Cooling Systems was trusted to be an integral part of Ford’s new aluminum offering, and in the end proved once again to be up to the task presented by one of the world’s most recognized and enduring brands.

Background

ExxonMobil is the world’s largest publicly traded international oil and gas company. They hold an industry-leading inventory of global oil and gas resources, are the world’s largest refiner and marketer of petroleum products, and their chemical company ranks among the world’s largest. Through the application of science and innovation they find better, safer and cleaner ways to deliver the energy the world needs.

ExxonMobil’s Joliet, Illinois Refinery is a key supplier of refined petroleum products to the Midwest, a leader in energy efficiency among U.S. refineries, and a prime example of a facility that uses new technologies to stay ahead of the industry curve. Recently, they purchased and installed the Tracerco Profiler™, which is a nucleonic instrument used to measure vertical distribution of oil, gas, foam, emulsion, water and sand in real time at high resolution. This patented instrument is a ‘window’ into a vessel, which enables an operator to improve production throughput, reduce the number of unscheduled shutdowns and achieve significant cost savings.

The main component in this system is a radioactive isotope, which generates large amounts of heat during normal operation – this condition requires an integrated, fail-safe cooling system to operate. Since the Profiler doesn’t include this cooling system, ExxonMobil called upon their trusted engineering and consulting partner, Ambitech, to find a company who could develop one for them.

Ambitech wasn’t simply looking to place an order for a piece of equipment; they were looking for a trusted partner who could deliver a custom solution on time and with no surprises for one of their most-significant clients. After an exhaustive search they found Fluid Cooling Systems (FCS).

Execution

The level of detail and thorough preparedness of ExxonMobil’s planning and engineering team was impressive. This helped FCS to hit the ground running, which was essential in this situation with a tight timeline and a high-profile client. After passing the extensive vetting process, digesting the specifications, passing a shop inspection, conducting a site visit and adhering to a host of other vetting procedures, FCS was ready to start in earnest.

From the onset, every member of the FCS team had to become intimately aware of all project requirements – this meant having to understand the documentation inside and out. Doing so helped make production and inspections more efficient since everyone was working toward shared goals and understood all requirement details.

FCS documented every process required to complete this project. In several instances, new processes were developed to meet ExxonMobil’s specifications. These were all presented to ExxonMobil and Ambitech who reviewed, commented and approved each process.

Since frequent third-party inspections were part of the requirements, the FCS team decided to take advantage of them. They forged a great working relationship with the inspector, who was tough but fair. FCS treated inspections as an opportunity to get one step closer to delivering the final product.

Construction was time-consuming, mainly because of the stringent specifications and frequent inspections. However, working through a thorough process every step of the way helped ensure the end product was problem-free and could be shipped to the job site as specified, without any quality concerns.

The Outcome

The custom cooling system shipped within the agreed-upon timeframe with virtually no issues along the way. As of 14 months after start-up, there have been no warranty calls.

This project was a big milestone for FSC because it was their first oil and gas project and helped them diversify into a market that’s hard to penetrate. It also provided the opportunity to formalize long-held processes and establish new ones that will benefit future projects and help them strive for continued excellence.

FCS was able to forge deep relationships with key stakeholders. They adhered to strict requirements and proved they are capable of following detailed specs and delivering as promised. It is not lost on them how fortunate they are to have been considered for this project. And, they proved to be more than up to the task of providing a first-of-it’s-kind solution for one of the world’s largest and most recognized companies.
