Red Hill Pipeline and Upper Tank Farm

Whether your project is large or small – our comprehensive piping design services will find a solution that will give you confidence and peace of mind. Coffman provided multidiscipline engineering design for the replacement of over 350 feet of 12-inch above and below ground pipeline and valves at Pearl Harbor to allow for simultaneous filling of two fuel tanks. In addition to the piping design, we also provided an analysis of the pipe supports, post-repair inspections, and a hydrostatic test.

Coffman provided civil, structural, and mechanical engineering design for the pipeline replacement and also civil engineering for the underground portion detailing the containment liner penetrations and repairs.
