ABSTRACT:
A subsea connection system includes a rigid vertical main connector (23) and an active (mobile) lateral connector (24) coupled to a subsea module (20) for connection, respectively, to a main mandrel (25) and to a lateral mandrel (26) rigidly fixed to the structures (27, 28) set at the seabottom. The active lateral connector (24) utilized in this system is provided internally with a locking and sealing set which is supported by pins (39) held in the orifices (40) of an intermediate jacket (41) which, in turn, is supported by pins (45) circumferentially offset at 90.degree. in relation to the orifices (40).
