How we deliver

Project delivery, quality & HSE

Across the asset lifecycle

Quality

We operate a documented quality management system structured on ISO 9001:2015, applied to every engineering deliverable and every item that leaves our workshop. Design work is independently checked and approved; fabrication is inspected and tested against approved ITPs before release.

  • HSE management system aligned with ISO 45001 / ISO 14001 principles
  • Job hazard analysis and permit-to-work discipline
  • Offshore-competent personnel (BOSIET/HUET as required)
  • Environmental compliance with Nigerian regulations
