Germany-based Bilfinger said its Oman joint venture (JV) has won an extension of its contract to provide engineering and maintenance services to oil and gas company Petroleum Development Oman (PDO), Trade Arabia reported.

The JV has been providing all on-plot engineering, procurement services, construction, commissioning besides management services and maintenance support for PDO’s oil and gas projects in the North of Oman since 2011.

The contract with majority government-owned PDO will now run until 2021, with an estimated turnover of about $215m for Bilfinger, Oman Observer informed, citing the German engineering group.

According to the company’s CEO, Tom Blades, the extension of the contract was brought forward by a year due to the good co-operation.

PDO is the largest oil and gas production company in Oman responsible for over 70% of oil production and almost all gas production in the country.

It is majority state-owned, with Royal Dutch Shell as the second largest shareholder.

Bilfinger is active in the Middle East with around 4,000 employees in the Engineering & Technologies (E&T) and maintenance, modifications & operations (MMO) business segments.
