These projects involve reviewing custom‑built equipment to ensure it meets the engineered requirements mandated by Occupational Health and Safety. Designs that were originally created without formal engineering oversight—such as custom built heavy‑haul trailers, lifting devices, and other specialized equipment—are assessed for structural adequacy, load capacity, and compliance with applicable standards. The goal is to provide the engineering validation and certification needed to support safe operation and regulatory approval.
A client had designed and built a custom piece of equipment, called a Schnabel neck, to haul an oversized vessel from Lewiston, Idaho, to Grande Prairie, Alberta.
Prior to permits being issued, an engineering design review and letter of certification was required.
The design was modelled and loaded with the appropriate loading, and the stresses were reviewed. A design certification was provided and the Schnable neck successfully completed a number of trips.
Miscellaneous lifting devices, either requiring an engineering certification, or requiring a capacity upgrade have been analyzed and certifications provided. This includes a lifting device for a centrifuge bowl, a custom built- wall panel lifting device, a valve body lifting cross, a custom device for lifting a reel of COROD®, and a custom lifting device for wood matting.
In the Oilfield Industry there are many specialized and customized pieces of equipment that have been made to meet operational requirements, that need to have engineering ratings provided. This ranges from cable support structures, to overhead crane trolleys, doghouse raising systems and even pipe arm handling systems.
