Innovation For Any Industry
Proven and Tested Performance
KES has proven itself time and again in developing key innovations in a wide range of fields. Our success is based on our comprehensive approach, expert use in tools, and creativity in developing innovation based our knowledge in multiple industries and disciplines.
Stress & strain is stress & strain. Heat transfer is heat transfer. Fluid flow is the same regardless of whether it’s in a chemical pipe, blood vessel, or aviation fuel line. The physics do not change because of the industry used. Our proven methodology is based on detailed problem identification, goal-oriented solution development, and creativity to overcome traditional obstacles. Our Clients are the experts in their fields. We work with their expertise to develop the solutions for their challenges regardless of the industry, applicable codes, or location.
Often our work remains proprietary and confidential. We ensure our Client’s interests are safeguarded. Our expertise is in providing solutions, therefore maintaining confidentiality is key to maintaining those relationships. Other times we help our client secure Intellectual Property such as patents and trademarks. We also help with procedures, policies, and communications since how equipment is used can be as much of an challenge as the design and fabrication.
We volunteer time and other support to advance innovation for the state and the nation:
- Manufacturing Extension Partnership of Louisiana
- LouisianaBio: Building a Statewide Biotech Community
- ASME Codes and Standards Committee for Pressure Vessels for Human Occupancy (PVHO)
- LSU College of Engineering Capstone Program
We are proud to be veterans and hiring veterans and Louisiana citizens. The skills, adaptivity, and focus on getting the mission done are our keys to innovation. #builtbyveterans
Our work in patents range from helping Clients develop their drawings and technology without contributing to the patent itself, to co-developing technologies with our Clients, to independent patent development. Our work ranges from industrial equipment to consumer products to biomedical devices.

Solar Pump Design
Sidewinder Pumps is based in Lafayette, La. They have over 30 years of leadership in chemical metering pumps. They approached Kemper Engineering to assist them in developing a novel solar-powered pump for applications away from grid-based electrical power.
Solar powered items are essentially battery-powered. The challenge is to make the equipment as efficient as possible with respect to energy draw in order to minimize battery use. KES used Finite Element Analysis, Computational Fluid Dynamics, and Kinematic Modeling to assist in the product’s development.
Pipeline and other remote sites are unforgiving. Either the equipment works or it does not. No amount of engineering simulations trump the real world. The Sidewinder Solar Pump became one of their best-selling products, driven by industry response to their demonstrated reliability and ease of maintenance. A more in-depth discussion is here.
New Applications for Acrylics
Krista Kemper, our owner, and Bart Kemper, our principal engineer, are both on the ASME Codes and Standards Committee for Pressure Vessels for Human Occupancy. One of the challenges in the field is the use of acrylics for windows. Acrylics have been proven to be the most reliable method for diving bells, submersibles, medical chambers, and other PVHO applications. However, they are a nonlinear viscioelastic material. The current rules use a very empirical method for window design.
KES has considerable experience with pressure vessels, plastics, medical applications, and advanced computational modeling. In working in multiple aspects of the industry, there was a need to expand the applications of acrylics as a pressure vessel material. However, this had to be done safely and reliably.
KES researched existing work as well as partnered with industry leaders. Based on this, rules for how to apply nonlinear and linear Finite Element Analysis to acrylic windows and proposed rules for eliminating the cyclic limits were proposed and accepted as a peer reviewed paper. This could have significant savings on those designs in which the windows have large design margins. Current rules have a hard limit on the number of cycles. The proposed novel methods, if accepted by the committee, will allow for a Code change and open the path for more innovations by KES and others.
This work was presented at Underwater Intervention 2013 and the 2013 Joint ASME/USCG Marine Technologies Conference where it was published as a peer review paper. An updated presentation was made 13th Annual Manned Underwater Vehicles Symposium, held at the 2016 Underwater Intervention conference.
Novel Vehicle Barrier
Our Client was experiencing challenges in crash testing their new barrier design. The tests were averaging $100,000 per test. The Client’s buyer was waiting for a fully engineered, certified tested production model.
KES provided 3rd party design review and test reviews. Finite Element Analysis and kinematic studies were used. The root cause of the challenges were determined and addressed. By developing new methods and computational models, KES helped our Client to get successful tests.
The device had to be approved by the Federal Highway Administration per NCHRP 350. KES correlated the computational models to all of the tests, successful and otherwise, to show the models and proposed construction methods were validated through performance. The FHWA accepted the report and tests and approved the device.
A peer-reviewed paper was later developed and published at the 2002 ASME International Congress. KES continues to use these principles for evaluating cable-related arresting barriers and fences and has provided novel designs for industry and government applications while safeguarding proprietary techniques of their original client. (This was done by current KES personnel in the previous company, Kemper Imageering, Inc.)
Years later for a separate client, KES assisted in developing a crash gate using different techniques. We solve the client’s challenges without compromising trade secrets or our other clients.
Blast and Force Protection
“Civil engineers build targets, mechanical engineers take them down.”
This old adage still holds true. However, having a detailed understanding of the mechanical side allows for better development of force protection methods.
Bart published a peer-reviewed paper about Lessons Learned in Iraq and was presented at the ASME International Congress in Seattle, Wa. in 2007. This addressed how cultural issues, traditional engineering, and military issues are intertwined in austere or expeditionary environments. Even if an engineer is not in the military, often military-related issues come up in terms of site security, anti-terrorism threats, and in working with foreign governments.
One of the lessons learned while working overseas in Asia, Europe, the Middle East, and Africa is the variability of materials. Many of the Western designs assume quality that is not reasonable or cost effective in austere environments. His work has been cited in various training programs.
Bart developed a blast wall that is highly effective for close-in explosions, such as due to vehicle-borne improvised explosive devices (VBIEDs). Where conventional methods such as a single concrete wall simply increases casualty rates, this design can confine the damage to a planned area. KES has proven history in civil, industrial, and governmental applications for blast, ballistics, fire, chemical release, and protective structures.
Design Responsibility, Code Applications
Bart and Krista are on the ASME Codes and Standards Committee for Pressure Vessels for Human Occupancy. These devices have all the challenges of a Section VIII (Div. 1 or Div. 2) pressure vessel, plus have large openings often outside of code requirements, plus have acrylic windows, and finally has all of the challenges of life support under often inherently deadly conditions. KES’ expertise has resulted in innovative engineering regarding applying the ASME pressure vessel code, to include for large tunnel boring machines using “dry diving” as well as traditional commercial saturation diving. KES published their successful techniques in 2013 as a peer-reviewed article at the 2013 ASME/USCG Marine Technologies Conference in order to advance the application of pressure vessel technologies. The audience included members of the US Coast Guard’s marine engineering section that conducts design reviews and had strong endorsements during the conference.
Bart also shares innovations he developed while serving as a Reservist. In 2003 he applied industrial fire and gas release modeling packages to real-time military operations planning. As the potential for unusual terrorist attacks have increased, the need for addressing them has also increased. In 2004 he presented a peer-reviewed paper about Design Responsibility at the 2003 Ethics and Engineering Conference and the 2004 Louisiana Joint Engineering Societies Conference as well as at the United States Military Academy
