Oene Roorda, P.Eng. is an engineering consultant with 35 years of experience in the oil and gas industry, specifically in materials selection, corrosion, welding, failure analysis, valve design, and manufacturing. He has worked for various leading EPC companies, oil and gas operating companies, and manufacturing companies.

Oene is an innovative thinker with effective, practical, goal oriented trouble-shooting skills. He held lead positions in engineering management, assembled and led multidisciplinary teams in design development, complex failure investigations, and operational troubleshooting.

Materials selection, corrosion and welding

Oene has successfully led teams of 5 to 15 people in EPC companies (Bechtel, Bantrel, Toyo, Jacobs, Fluor, Worley Parsons, and others) to complete material selection on a wide variety of Oilsands mining, SAGD, Bitumen Production, Oilsands Upgraders, and Refinery facilities. Produced MSDs, Materials Selection Design Basis documents, and provided ongoing project support in the areas of corrosion, welding, NDE, and quality assurance.

Oene is experienced in the development of piping material classes. He developed a new and unique database product to streamline the development of piping material classes and to simultaneously generate the files needed for the setup of 3D-CADD piping design and modeling.

Oene has successfully developed Corrosion Control Documents (API RP580 and RP970), Reliability Based Inspection, and Integrity Operating Windows for many operating companies (Shell, NorthWest Upgrading, Exxon, BPCL, and others) a wide variety of Oilsands mining, SAGD, Bitumen Production, Oilsands Upgraders, and Refinery facilities (CDU, NHT, CCR, FCC, VGO-HDS, Hydrocracker, Hydrotreater, Aromatic Recovery, SWS, ARU, SRU, and others). He facilitated on-site CCD and troubleshooting workshops at the refinery with inspection, process, and operations specialists.

Failure investigation

Oene has successfully completed complex failure investigations and associated operational trouble shooting. Failure investigations included corrosion and welding related failures, fires, and fire damage assessment. Failure investigations involved a wide variety of damage mechanisms, like stress corrosion cracking, high temperature corrosion, brittle fracture, sulfidation, naphthenic acid corrosion, creep, and soil corrosion. He has applied a wide variety of investigative techniques, like in-situ metallography, light and SEM metallography, and fractography as well as analysis techniques, like XRD, EDS, and XPS.

Valve Design

Oene has specialized knowledge of check valve design, manufacturing and operation. He has designed and optimized various nozzle check valve, swing check valve and dual plate wafer check valve designs. Successfully optimized nozzle check valves for Mannesmann Demag by reducing its pressure loss by 70% and developed unique nozzle wafer check valves with single (disc) and dual-annular (ring disc) diffusers. These valve designs are currently manufactured and by Mokveld, Noreva-Goodwin, Cameron and Grayloc.

His design work led to two patents:

  • Patent US 2010-0101668 (pending) for dual-spring closing action in non-slam nozzle check valves
  • Patent US 6,443,183-B1, Valve and Assembly for Axially Moving Members
