Abstract
The invention relates to a method for controlling a device for transporting hydrocarbons in the form of a mixture of liquid and gas between production means (1) and a treatment plant (10). The method according to the invention for controlling a device comprising a hydrocarbons transport pipe (6) fitted with an adjustable-aperture outlet choke (9) to which a gas-injection pipe (16) fitted with a control valve (15) is connected, is characterized in that it includes a start-up phase which consists in performing the following sequence of steps: PA1 a step of initiating the transport of hydrocarbons, PA1 a step of ramping up to transport speed, then a production phase, during which phases the outlet choke (9) and the control valve (15) are operated in such a way as to maintain the stability of the pressure in the pipe (6) for transporting the hydrocarbons produced. The invention finds an application in the operation of off-shore oil production installations.
