Our history

Antenor-OTG was established in 2003, and is the result of a merger between Antenor AS and OTG Consulting AS.

OTG Consulting has provided consultancy services and conducted more than 500 studies in risk analysis, technical safety and HSE. This includes deliveries to the petroleum industry, drilling and well operations and to onshore infrastructure projects.

Antenor has developed the Antenor Business Management System (BMS) software, a digital tool for corporate governance and continuous improvement. Accompanying the software, we offer skilled specialised consultants. This combination enables Antenor as a company to help hundreds of companies with their QMS. We offer everything from training and short term assistance, to long term assignments that contribute to various ISO certifications, digitilisation and more efficient processes.

Combined we are one of the leading companies in Norway within our field of expertise.


Delivering software and services within the quality, risk, HSE and technical safety segment means that we can contribute to the sustainability process of our customers. The ESG principles are central to the development of management systems and efficient processes, and focus on achieving better results with less use of resources.

Our own delivery models have good environmental effects. Cloud-based technology significantly reduces server usage for our customers. However more importantly, our digital delivery models allow us to conduct onboarding and support for our system customers digitally. Audits and risk analyses can be done digitally. Cloud technology opens many new opportunities which we, as a company, are more than ready to make the most of.  Finally , our customers save considerable costs and saves the environment of unnecessary CO2 emissions.
