About VAOS
Who we are

History
VAOS was established in 1983 to provide a comprehensive construction and maintenance service to the oil, gas and petrochemical industry in Libya.
At its inception VAOS was a discrete division of Voest Alpine AG, which at the time was the largest state-owned industry in Austria.
Voest Alpine, with its headquarters in Linz/Austria, was then subject of a major restructuring programme leading to the formation of VA-TECH, an industrial holding company, at the time comprised of a number of smaller companies, such as Voest Alpine Machinery, Construction and Engineering (VA-MCE).
​
In 1994 VA-MCE opened a fully owned subsidiary in Malta, becoming the new head office of Voest Alpine Oilfield Services Limited.
As part of a subsequent company restructuring transition period between 1994 and 1997, VA-MCE sold off its shares to management; this led to the formation of the current company, Value Added Oilfield Services (VAOS Limited).
Since then, VAOS has been operating successfully as an independent privately owned company.

Integrated Management Systems
Safety first​
VAOS’ Quality Management System was independently certified to ISO 9001 in October 2004, covering construction, installation, revamping and maintenance of facilities and components for the crude oil and petrochemical industry, including automated sludge recovery and tank cleaning activities.
To strengthen operational safety, VAOS integrated a Safety Management System aligned with ISO 45001, creating a fully integrated management framework.
In 2007, VAOS successfully completed its ISO 9001 recertification and initial ISO 45001 certification. Since then, the company has passed all subsequent audits and is currently certified by TÜV Austria Hellas.
VAOS continuously strengthens its environmental management practices in line with ISO 14001 requirements.
