Quality Throughout

Our craftsmen take pride in the precise execution of offshore engineering designs. Products that simply look great and fit perfectly naturally give a reassurance that construction has been done right. Pride of workmanship takes projects a big step above "good enough."

Quality Targets

While we always strive for perfection, our targets help us gauge performance:

  • Welding primary pass rate above 95%
  • Quality of service up to 98%
  • Project quality meets 100% pass rate
  • Customer Satisfaction above 92%


ISO 9000 certificates

Various certifications to customer and industry standards provide baselines for best practices in offshore engineering, from which we seek continual improvements.

  • Offshore Facility Maintain Certificate issued by CNOOC
  • Subcontractor Safety Certificate issued by COOEC
  • Vessel and Offshore Facility Service Company Certificate issued by CCS
  • Management System Certificates for ISO9001:2000, ISO14001:2004, and OHSAS18001:2007

From calibrating torque wrenches to radiographic weld inspection, from carefully inspecting materials received to verifying mill test certificates, and from applying industry standard design tools to cross-verification of analysis—quality control is a pervasive ingredient of our work.
