Libya’s Waha Oil Company (WOC) has invited companies to prequalify to bid on a tender for the replacement of two underground oil pipelines in the north of the country.

The tender will cover the replacement of a 30-inch, 70-kilometre underground oil line from Dahra Central to Bahi Junction and a 24-inch, 270-km pipeline from Zaggut to Es-Sider Tank Farm.

The pipelines will be laid parallel to the existing structures and retain the same size as the ones being replaced.

WOC requires companies to submit prequalification documents by 4 June. Successful contractors will then be sent invitations to bid for the contract.

WOC is a subsidiary of Libya’s state-owned National Oil Corporation (NOC) and operates several onshore oil fields in the central north of the country.

The North African country is ramping up production at its major oil fields following the civil war, which resulted in the death of former leader Muammar Gaddafi in October 2011.
