We are committed to delivering services that bring significant and defined value to our customers. We execute on this commitment by providing innovative, timely and cost-effective solutions.

Some of our recent successes include:


  • Over $0.5MM in capital costs saved from our recommendation to configure a new waste water treatment system.
  • Over $3MM in operating costs saved from our recommendation to prefabricate equipment with refractory to allow single weld assembly in field saving more than 3 T/A days from critical path
  • Over $500,000 in annual energy costs saved by debugging the controls of a multi-tier steam system during the course of scope development
  • Over $250,000 in capital costs saved from our recommendation to convert existing out-of-service piping into in-service piping, thereby eliminating the installation of 1.5 miles of new piping

Process Industries

  • Over $2MM in capital costs saved by implementing process improvements in solvent and stripping technology to an existing extraction technology
  • Over $150,000 per year in energy and maintenance costs saved by retaining us to replace obsolete eddy current drives with state of the art variable speed drives

Pipelines and Terminals

  • Over $150,000 in capital costs saved by our recommendation to utilize displacement auger technology for cast-in-place pile installation
  • Onyx created significant reductions in demurrage by developing the optimal use of a terminal transfer unit and rearranging terminal utilization based on market driven factors. This lead to a full rationalization of terminal utilization and subsequent preparation of the terminal for on-line blending.
  • Onyx .5MM in savings by estimate preportaion, detailed engineering and designing of an expansion to a truck rack loading facility for all grades of motor gasolines and ULS diesel fuel. Relocation of existing pumps along with foundations, power and instrumentation for new equipment was required.
