Design Engineering

Design Engineering

Allan R. Nelson Engineering offers a broad range of specialized mechanical design engineering services. Whether the job requires a new mechanical design or a modification to existing equipment, our customers receive innovative and cost-effective mechanical design engineering solutions.

We provide design engineering solutions for:

  • Drill and service rig masts and substructures
  • Mast and substructure modifications and load ratings
  • Vertical and slant hole flushby rigs
  • New machinery for various industries
  • Lifting frames and systems
  • Existing equipment modifications
  • Pumping systems
  • Overhead Equipment

Our mechanical design engineering department uses Finite Element Analysis (FEA) to understand the physical effects on mechanical component designs, systems and structures. The application of these advanced modeling techniques to mechanical design engineering provides visual representation of complex data to provide clients with optimal designs.

FEA is a significant tool used in our engineering analysis. It allows us to perform stress analysis, including dynamic analysis of vibration, shock or fatigue. By using FEA to review a design it is possible to identify problems that may occur while the part is in service, without having to experience a failure in the field.
