About the Company:
1983 - Start of VAOS Limited was established to provide comprehensive construction and maintenance service to the oil, gas and petrochemical industries in Libya in 1983. Originally it started operation as a division of Voest Alpine AG, the biggest state owned industry in Austria at that time. Later, Voest Alpine with it’s head office in Linz/Austria went through a major restructuring program and converted into VA-TECH, which held many smaller companies, Voest – Alpine Machinery, Construction and Engineering GmbH amongst others. In 1994 VA-MCE opened a fully owned subsidiary in Malta, this being the new head office of Voest Alpine Oilfield Services Limited. Another restructuring program took place in 1997 and in it’s course VA-MCE took a strategic decision and sold it’s shares to the management at that time. Resultantly, the company’s name was changed to the present one. Since then, VAOS has been operating successfully as an independent private company.
VAOS provides clients with a ‘one stop shop’ service for maintenance, repair and new construction. We meet predetermined delivery dates. This saves our clients’ time and money and ensures continuity of their supply capability. VAOS has the technical expertise to complete comprehensive plant rehabilitation and modernization.
We provide civil engineering solutions backed by professionalism in steelwork construction, equipment installation, electrical supply, instrumentation, pipework, insulation and corrosion protection. Our project managers are the best in the business, having many years of ‘hands-on’ practical experience in the field.

VAOS drilling division operations
In general, while performing for their previous employers , VAOS Drilling Division personnel have taken part in the execution of the following activities :
Water Well Drilling (Civil Sector)
Drilling and completion of water wells, piezometric and observation wells with total depths ranging from 80 to 2300 m.
Cathodic protection (CP) hole drilling
Drilling, anode-placing and chemical backfilling works on CP holes and deep CP wells with total depths reaching to 1225 feet.
In July 2003, VAOS has entered into a subcontract agreement for the drilling of 40090, with an average depth of 10 m and installation of sacrificial anodes for corrosion protection of the GREAT MAN MADE RIVER - our contribution to one of the largest projects in engineering history.
The execution of the project is scheduled to start in October 2003 and the scope of works covers also the anode and chemical backfill installation.
VAOS is proud to offer its clients high quality Computerized Well logging Services. VAOS has extensive experience of borehole logging operations in Libya and can usually mobilize at short notice for single-hole or long-term contracts. The entire range of VAOS equipment is available on a service basis operated by our own highly-trained personnel.
VAOS provides logging services with one Geo Vista vehicle mounted Well Logging Unit based on a Mercedes “UNIMOG” van truck crew-cab body, 4-wheel drive, designed for desert use. The winch is Heavy duty hydraulically operated with following specification: capacity: 3000 meters and speed: 0-30 m/min. The electrical wireline is a steel armored cable with seven conductors and 5/16 ” outer diameter, 1900 m length.
The surface logging system is a state of the art unit capable of interfacing between a stack of logging sondes and the surface computer. All data communication is controlled from the GeoVista logger surface unit. A stack logging system is one where several sondes can be screwed together and run as a single tool string. The advantages of this are speed of operation (less trips in the hole), control of measurements made in a single run . These are significant advantages, particularly where a varied logging programme is envisaged.
Our Well Logging Technology
Our log data in LAS format can be imported into commercially available log processing software like for instance Viewlog of Viewlog Systems and WellCad of ALT. These offer useful options for log computations, corrections, correlation and versatile presentations.

Tank Cleaning Service:
Sludge Recovery and Tank Cleaning Services
Libya is a major player in the world oil market and is presently experiencing high levels of investment within the oil industry to comply with the increase in oil production. Maintenance of processing equipment and storage tank facilities are consequently of high priority. Before maintenance can begin, tanks must be emptied for sludge and cleaned.
Libyan Zueitina Terminal asked VAOS Ltd. to clean a crude oil storage tank of 79,000 m capacity, with 5,300 m3sludge content. VAOS provides tank maintenance, repair services at refineries, oil fields, and tank terminals, and a broad range of construction of oil equipment to the Libyan oil industry.
The Zueitina tank was one of the tanks in need for inspection and maintenance. Before it could be repaired and brought back on-line, it needed a thorough cleaning. This presented VAOS with several challenges: a double floating deck made access a difficult proposition, and the tank’s contents of crude oil sludge and hazardous petrochemicals presented risks to VAOS workers.
A fast and safe tank cleaning VAOS cleaned the tank recovering 4,969 m3 of crude oil for Zueitina. Throughout the entire project, no VAOS workers ever had to enter the tank or risk exposure to potentially harmful substances.
Zueitina Terminal saved more than 700,000 USD
VAOS turned the Zueitina tank from an obstacle into a stepping-stone, by making it the first job in which they used the BLABO® system.
The latest Sludge Recovery job VAOS has performed for a Libyan client meant that no less than 22,600 m3 of sludge was recovered, representing a value of several million USD.
Vaos recovered 94% of the oil in Zueitina’s tank – representing a savings of more than 700,000 USD. In addition, the job was completed with total environmental safety: normally, oil recovered from a tank cleaning job ends up in desert oil ponds.
Automated cleaning enabled Zueitina to safely recover the oil and transfer it into other tanks. During tank cleaning, it is normal practice to empty the waste oil into the desert, where slop oil ponds are formed, severely damaging the environment.
