think in general the transit networks need modernization and a good example of that is also the north sea project which is now for its first stage nearing completion to great success which will also ensure stable long term supply so one modern system and on the modern management all i can say about the ukraine situation is that it is clear that all the partners in the south stream project have collectively. agreed that and this is just obvious from the actions they are taking now that it would not be wise to and tire leaders rely on the ukraine for fuel. your transit for the kind of volumes that have been flowing still there so far so. what that then sums up to is really the ukraine will likely continue to play a role in transit to europe but we will also have a modern today and well managed transit system in the form of south stream. which implies that there is going to be additional security of supply or for your call of the south stream promises to two to come up to sixty three billion cubic meters of gas three years do you already know the source is going to get the gas to fill the pipe. well

if you look at pipeline projects for natural gas such as north stream but also many many others in the north sea for example the norwegian sector the british actor etc and elsewhere in the world you can really say that transporting natural gas in a biplane on the seabed is not in itself at all. there's exercise now that being said for the specific road you have to of course of any negative impacts on the seabed and on the environment where you can but transporting. through. an area such as the black sea in itself is a perfectly safe activity. when will the final agreements one move they be signed with. the false and also the winter shall the french and the german companies about the condition of their participation in your project. well they're working hard together to. resolve. some outstanding issues this is a large and complex project so naturally as has been the case in other projects this takes some time but i am confident none of them wants to take it any longer than necessary so we're looking forward to the conclusion but it's not in my hands to turn tiredly and there's. another question
