Pipelines and subsea
Ramboll has more than three decades of experience with offshore infrastructure. We cover transmission pipelines as well as infield flowline systems from concept to design. For maturing pipelines, we handle all aspects of brownfield-engineering related to the reassessment of structural integrit.
We design complex High Pressure/High Temperature (HP/HT) flow lines, and we are specialised in subsea tie-back projects with topographical challenges combined with HP/HT operation.
Our proven pipeline engineering competencies are based on an advanced understanding of critical issues such as structural behaviour and hydrodynamics under adverse conditions. We offer offshore expertise in route selection, geophysical and geotechnical route surveying, system optimisation, laying and trenching analyses, riser systems, flow assurance, subsea components and installation
Ramboll provides a full set of subsea operation services in connection with subsea pipeline design. Our subsea engineering includes know-how regarding:
Ramboll supports clients in increasing efficiency and prolonging production on mature fields. Our in-depth knowledge extends to offshore platforms and FPSOs, which gives us the required overview and experience to handle tie-back or tie-in projects for all relevant interfaces between pipeline, subsea completion and platform or FPSO.
Based on our multidiscipline profile, Ramboll can also assist in connecting subsea highways with onshore infrastructure by engaging our civil engineering expertise such as ports & marine, roads, construction and contract management.
The Polarled pipeline project is part of the plans for developing fields further north in the Norwegian Sea.
Ramboll was awarded a FEED study for Balticconnector - an offshore 20” gas transportation pipeline of approximately 81 km (50 miles) in the Gulf of Finland aiming at interconnecting the Finnish and Estonian natural gas distribution networks.
Kirinskoye is the first offshore field in Russia to utilise a subsea system for natural gas production. The field holds over 100 billion cubic metres of gas and 11.4 million tonnes of gas condensate.
The Kirinskoye gas and condensate field is part of the 'Kirinsky block' in the Sea of Okhotsk and is one of the main development priorities for Gazprom, the world's largest gas producer. The field is part of a Russian Federation strategy for development of an integrated gas production, transportation and supply system to the regions of Eastern Siberia and the Far East.
European gas consumption is increasing, and in order to meet these demands and ensure a long-term reliable supply line of energy, it was decided to establish a 1,224 kilometre dual pipeline system running from Vyborg, Russia to Lubmin near Greifswald, Germany. The project is called the Nord Stream Pipeline.
As part of the Sleipner SPORT development project, satellite platform Gudrun was tied-in to Sleipner, for oil and gas processing and export. Statoil awarded Ramboll the FEED and detailed engineering of the subsea pipeline system.
As part of the development of the Sleipner area, Statoil planned to utilise existing process and export facilities for production from satellite platforms. Statoil selected Ramboll to perform FEED and detailed engineering of subsea pipelines to the satellite field, Gina Krog.
