The group announced the attack on the Escravos tank farm near the main electricity feed pipeline through which power is supplied to the oil facility.
The latest attack in the early hours of Thursday was confirmed through the group’s Twitter handle, @NDAvengers.
“We warned Chevron, but they didn’t listen. NDA just blew up the Escravos tank farm main electricity feed pipeline,” the groups said.
The NDA explained that the oil facilities were sabotaged following attempts by Chevron to carry out repairs of main Escravos crude oil pipeline it blew up earlier.
Reuters quoted sources as saying that the company’s onshore operations in the Niger Delta had been shut down following the attack, which involved the main electricity line leading to its Escravos terminal.
“It is a crude line, which means all activities in Chevron are grounded,” the source told Reuters.
After the initial attack, the group had warned against moves to repair the facility until their demands were fully met.
Last week, Chevron’s Makaraba crude oil line was attacked on the offshore Okan manifold in the region.
The attack followed previous ones on the company’s facilities at Abiteye, Utunana and Makaraba platforms in Warri South-West area of Delta State resulting in the loss of over 40,000 barrels of oil per day.
The management of Chevron Nigeria Limited declined comments on Wednesday’s attack.
Sola Adebawo, manager communications and government relation at CNL said the oil firm would not immediately comment.
“We are not able to comment at this time,” Mr. Adebawo said in a text message on Thursday.
Residents in the area said that an explosion occurred on Wednesday night.
Eric Omare, Spokesman for Ijaw Youths Council confirmed the incident but did not provide details.
