Energinet gets DNV certification for Baltic Pipe natural gas pipeline

Energinet, the Danish national transmission system operator for electricity and natural gas, has received certificates of conformity from DNV for its section of the 10-billion cu m/year offshore Baltic Pipe natural gas pipeline running from Norway to Denmark and Poland. DNV’s work on Baltic Pipe, which began operations Oct. 1, 2022, took place during its engineering, procurement, construction, installation, hook-up, and commissioning phases.

Energinet's part of Baltic Pipe consists of 105 km of pipeline in the North Sea, 210 km of pipeline underground across Denmark, an expansion of the Nybro gas terminal, and a new compressor station at Everdrup in Southern Zealand, Denmark. DNV assisted with professional services to Energinet on the onshore pipelines, compressor station, and gas terminal.

Commissioning of Nybro terminal took place in two stages, half of its 6,700 Mw-hr/hr capacity coming online Nov. 1, 2022, and the second half before the end of the year. Gas started flowing to Poland at partial capacity on Oct. 1 as planned. Everdrup compressor station uses three 18.8-Mw electric motor compressors, with two operating and the third serving as a spare. 

DNV’s overall contract scope included independent verification, complex independent modelling, and submarine pipeline certification to DNV certification regime DNV-SE-0475. Acceptance criteria met Danish Continental Shelf Law, DNV-ST-F101, and the suite of underlying DNV standards and recommended practices.
