摘要

The invention concerns a method and installation for connecting a rigid submarine pipeline (18) and a flexible submarine pipeline (20), said rigid submarine pipeline (18) terminated by a free connecting end (22), said flexible submarine pipeline (20) having a sea floor portion (32) and a suspended portion, said sea floor portion having an input end (19) connected to said free connecting end (22), said installation comprising anchoring means (26, 24, 30) for maintaining said sea floor portion (32) anchored in an anchoring point (28) of said sea floor portion and for allowing said sea floor portion to form an undulation (38). The invention is characterized in that the anchoring means are adapted to maintain said anchoring point (26, 24, 30) spaced apart from or closer to said free connecting end (22) to form said undulation (38) between said anchoring point (28) and said free connecting end (22).
