Abstract

An underwater connection assembly, and a connection method, for connecting a riser ( 12 ) and a flexible pipe ( 26 ). The riser ( 12 ) has an upper connection end ( 52 ) and the flexible pipe ( 26 ) has a lower connection end ( 30 ). The connection assembly includes a longitudinal frame ( 36 ) having a foot ( 46 ) rigidly connected to the upper connection end ( 52 ) and a head ( 42 ) linked to a float ( 20 ). A connector ( 34 ), and a curved pipe ( 32 ) having two opposing ends ( 62, 64 ). The opposing end ( 62 ) is rigidly connected to the lower connection end ( 30 ), and the connector ( 34 ) is mounted to the other opposing end ( 64 ), to be able to pull the connector ( 34 ) towards the upper connection end ( 52 ) in a direction oriented from the head ( 42 ) to the foot ( 46 ).
