Integrated Management System

As one of Europe’s leading riser manufacturers, it is crucial for us to guarantee and maintain a consistent and sustainable high standard of quality at all times.


As a direct result of our commitment to quality GTP successfully implemented a management system in accordance with ISO 9001 with accreditation a few years after the company’s foundation. The next logical step was to apply for ISO 14001 certification and this was achieved several years later. To demonstrate our commitment to the environment GTP initiated an energy management system to reduce waste and improve efficiency, and in November 2015 achieved the necessary conditions to be awarded with ISO 50001 certification. Yearly audits of our Integrated Management System ensure continuous improvement and efficiency of our process.
