In order to keep up with in influx of crude from Canada, the Port Arthur refinery, already exporting 275,000 barrels a day, had a goal of 600,000 barrels a day. Jacobs Engineering Group Inc. partnered with Bechtel to manage engineering, procurement, and construction for the $7 billion crude expansion project. Vibration was causing breakage of the bolts holding the clamps together, adding extra delays to a project that was rushing to expand. Jacobs Engineering Group, Motiva, and Bechtel worked with APP to design an entirely new approach to clamp liners — one that solved major time challenges and represented a significant reduction in vibration-related breakage in the piping system.

As the refinery expansion progressed, a recurring problem around clamp breakage was putting significant stress on the project timeline. The hold down clamps being used were held in place with a combination of a bolt and square washer — the bolts were breaking, requiring shutdown of the compressor to allow for replacement of the clamps and causing a significant setback. Jacobs had a hunch that rigid clamp liners were contributing to the problem. From there, APP’s idea of a poured rubber clamp liner came into being — and the VibraTek Hold Down Clamp and Liner were born.
APP looked beyond the broken bolt to the rigid clamp liner, working to counteract fit and delamination problems by creating a strong-yet-flexible approach to the liner itself. Motiva’s pain point became a moment of collaborative innovation, resulting in the custom (now standard) APP VibraTek Hold Down Clamp and Liner.
