Abstract: The present invention relates to an all electric subsea boosting system for well fluid boosting by compressing hydrocarbon gases and/or pumping hydrocarbon liquids where said system comprises one or more subsea boosting stations and one or more long step-out power supplies.

Abstract: A device in connection with a riser (1) for the transport of oil and/or gas, possibly including water, from a transport system, transport pipe (5) or similar structure on the sea bed to a platform or similar arrangement. To permit the use a riser (1) for the transport of oil and/or gas from a small field with low oil/gas production where a transport pipe (5) with a small diameter is used, a flexible pipe (4) with generally the same internal diameter as the transport pipe (5) is arranged inside the riser (1). At its upper and lower ends, the riser (1) is provided with a coupling (6, 7), which forms a seal between the transport pipe (5) and the flexible pipe (4) and also forms a seal at the ends of the riser so that the riser is closed.
