Abstract:
Method of stopping and restarting production in an undersea bottom-to-surface connection production pipe having a first pipe portion on the sea bottom from a well head to the bottom end of a second pipe portion extending to a ship or floating. When production is stopped, at least the first pipe portion is filled with a depressurized production fluid. Thereafter the following steps are performed: e1) forming a gel from two reagents in a first gel-forming chamber on the sea bottom; e2) sending a quantity of separator gel into the first pipe portion that pushes the cold fluid contained in the first pipe portion to the second pipe portion, prior to closing the first chamber; and then; e3) starting production, the gel forming physical separation and thermal and chemical isolation between firstly the production fluid and secondly a production fluid within the first production pipe portion.

Claim (Index 8):
The method according to  claim 7 , wherein the following steps are performed:\n a1) in step a), after isolating said second pipe portion from said first pipe portion, replacing the production fluid within said second pipe portion by injecting an inert replacement fluid into a second auxiliary pipe extending from a first tank on the ship or floating support on the surface to the bottom end of the second pipe portion isolated from the first pipe portion, preferably an inert fluid also including or constituting a hydrate formation inhibitor; and b1) in step b), performing additional depressurization of the first production pipe portion isolated from said second pipe portion and filled with production fluid, by reducing the pressure in said first pipe portion and more completely discharging the gas contained in the production fluid it contains, to an auxiliary gas discharge pipe extending from the end of said first production pipe portion closest to the bottom end of said second production pipe portion to the ship or floating support on the surface.
