The twin Nord Stream 1 and 2 pipelines have been leaking huge quantities of gas since they were damaged in a series of suspected explosions on September 26th.
In a statement issued on Tuesday, Nord Stream AG, the company which owns and operates the pipelines, said it had so far been unable to carry out its own inspections.
“As of today, Nord Stream AG is unable to inspect the damaged sections of the gas pipeline due to the lack of earlier requested necessary permits,” the company, which is 51 percent owned by the Russian gas giant Gazprom, wrote.
“In particular,” it added, “according to the Swedish authorities, a ban on shipping, anchoring, diving, using of underwater vehicles, geophysical mapping, etc. has been introduced to conduct a state investigation around the damage sites in the Baltic Sea.”
“According to information received from the Danish authorities, the processing time of the Nord Stream AG request for the survey may take more than 20 working days.”
The company said it was also being blocked by Norwegian authorities.
Nord Stream has chartered “an appropriately equipped” survey vessel in Norway, the company wrote, but the vessel has been denied the “green light from Norwegian Ministry of Foreign Affairs” to depart for the Baltic.
