Stockholm - An international consortium that wants to bring natural gas from Russia to Germany via an underwater pipeline handed in its revised application to Sweden on Wednesday.

"We will get approval, I am certain of that," Lars O Gronstedt, advisor to the Nord Stream consortium, told Swedish radio news.

The 1,200-kilometre-long pipeline through the Baltic Sea is envisaged to run through the Swedish economic zone, east of Gotland.

The Swedish government is to assess the application but has not set a date for a decision.

The revised application has taken into account concerns and questions raised by various Swedish authorities, research institutes, non-governmental organizations, citizens and municipalities affected by the project.

Nord Stream said it had decided to stick to its original route off Gotland.

"We fulfill all reasonable environment demands made by some 50 interested parties," Gronstedt said.

The Swedish Environmental Protection Agency has earlier recommended a more easterly route, citing the need to avoid areas used by sea birds.

Partners in the consortium include Russian gas monopoly Gazprom, German energy companies E. ON, BASF/Wintershall and Dutch company Gasunie. (dpa)
