Danmark-Fredericia: Bygge- og anlægsarbejder

All activities required to complete the work in accordance with the contract necessary for tie-in operations in connecting the new constructed onshore pipelines both between the individual construction parts and connection to the existing transmission system are separated in different types of tie-in: In particular this includes, but is not limited to, the following:• tie-in to the existing system being in operation. This means that a separation typically consists of one valve. Energinet will here check the tightness of the valve before the operation is carried out;• tie-in to the existing system in operation but separated with two valves and nitrogen filling between the two valves;• tie-in between two newly constructed sections with no connection to gas system in operation. Here the sections may be delivered with a slight overpressure of nitrogen or dry air. This is subject for check before the tie-in operation starts.
