The Ormen Lange Field is a natural gas field in Norway, located in the Norwegian Sea, situated 120 kilometres northwest of Kristiansund. With depths of the seabed that vary between 850 and 1,100 metres, the natural conditions at the site are considered harsh. The stormy seas, uneven seabed and strong underwater currents put great demand on Van Oord’s expertise and flexible fallpipe vessel Stornes during the pre and post-lay activities of Subsea Rock Installation.
The project scope involves the seabed intervention works consisting of pre-lay structure foundations, pipeline and umbilical route preparation. In addition, the post-lay SRI for structures protection, pipeline and umbilical cover related to the new development of a wet gas subsea compression project.
Once the gas subsea compression expansion is finalised the overall gas recovery rate will increase from 75% to 85%, used for the consumption of households in the UK and continental Europe. Being powered with hydro-generated electricity, Ormen Lange is considered one of the lowest carbon intensity fields in Norway, which resonates well with Van Oord’s company goals to contribute to the energy transition.
