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 11):
The method according to  claim 7 , wherein after stopping production, the following steps are performed:\n a2) in step a), leaving the production fluid in said first production pipe portion, and emptying said second pipe portion isolated from said first pipe portion by transferring the production fluid within said second pipe portion into a buffer tank connected to the bottom end of said second pipe portion, said buffer tank preferably being a buffer pipe extending on the sea bottom from the bottom end of the said second pipe portion; and b2) in step b), performing additional depressurization of the first production pipe portion filled with production fluid by putting it into communication with said second pipe portion and by more completely discharging the gases contained in the production fluid of the first pipe portion towards said second production pipe portion that has previously been emptied of all liquid.
