Engineering Approach

Design Philosophy

Most FRP failures trace back to design assumptions made by habit — wall thicknesses borrowed from a prior job, resin choices that worked last time.


Our methodology emphasizes:

  • Proven laminate specifications
  • Long-term chemical compatibility
  • Inspection and maintenance planning
  • Repair Procedure specifications


Our design philosophy is to maximize service life and reliability under exposure to aggressive chemistries and environmental conditions. We document every assumption at the start so that if conditions change, the system can be re-evaluated against a known baseline rather than guesswork.

Design Basis

A laminate specification is only as reliable as the operating parameters it was built around. Every project begins with a formal definition of the chemical environment, operating temperatures, fluid specific gravity, and structural load conditions. 


We document these assumptions explicitly so laminate specifications, wall thicknesses, and fittings are traceable back to real operating parameters. This traceability is what makes our designs defensible to regulators, insurers, and the engineers who inherit the system years later.

Material & Laminate Engineering

Resin selection is the single highest-leverage decision in FRP design — the wrong choice in an aggressive chemical environment may not show up immediately, but it will show up. The decision has to be driven by chemical compatibility data, not by precedent or cost.


We specify corrosion barriers, structural laminates, and exterior coatings as an integrated system — accounting for UV exposure, thermal cycling, and the specific corrosives present. Where standard laminates are insufficient, we develop custom schedules.

Structural & Dynamic Analysis

Storage tanks, floating barges, and pump platforms each carry distinct load profiles — and floating infrastructure in particular has to be designed for conditions that change constantly.


Our structural analysis addresses:

  1. Hydrostatic pressure
  2. Wind and seismic loading
  3. Pump vibration
  4. Mooring forces
  5. Dynamic fluid movement

 

Stability calculations account for variable pond levels, and asymmetric pump loading.

Design for Lifecycle Accountability

The most expensive FRP failures we've seen weren't only caused by faulty fabrication — they were often caused by operators who had no maintenance framework and no defined failure indicators to act on. 


We specify inspection intervals, define failure indicators, and develop repair procedures as part of the original design package. Operators have a maintenance framework from day one, rather than improvising after problems occur. Inspection intervals and repair procedures are not extra work; they are what separates a 20-year system from a 40-year one.

Independent Technical Review

Not every project calls for a new design. Sometimes what's needed is a second set of eyes — experienced, structurally independent, and qualified to read a design package honestly.
We provide independent technical review of FRP design packages prepared by other engineers. That includes new designs before they go to fabrication, as-built designs on existing assets, failure analyses on installations that didn't perform as expected, and owner's-engineer representation on FRP-heavy projects. The deliverable is a written review that identifies design issues, rates their severity, and recommends remediation or acceptance — backed by the specific engineering judgment we've developed across five decades of FRP installations in the field.
