Certifications & Integrated Management System (IMS)
Seven Star LLC maintains a fully integrated management system (IMS) certified by GQS – Global Quality Services, Germany.
Our IMS unifies four internationally recognized standards: ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), ISO 45001:2018 (Occupational Health & Safety), and ISO/TS 29001:2010 (Oil & Gas Sector Quality Management).
Through this integrated framework, we ensure that every project — from engineering design to procurement, construction, installation, and commissioning — is executed with consistent quality, environmental responsibility, and strict HSE compliance.
Our management system provides transparent control across all operations, promotes continuous improvement, and reduces risks in complex industrial environments.
All certifications are issued and audited by GQS (Germany) and remain valid until 16 October 2026.
They cover our complete operational scope in Oman, including automation & control systems, metering & analyzer solutions, instrumentation, mechanical and electrical works across oil, gas, petrochemical, refinery, and power industries.
