Abstract: A tie-in system (47, 48) for tie-in of a transfer pipe (13, 14) to a support unit (12) is disclosed, where the transfer pipe (13, 14) is arranged at least partly in a body of water (19). The tie-in system (47, 48) comprises: a spool piece (61, 71) that in one end is adapted to be attached to the transfer pipe (13, 14) and in the other end to be connected to a pipe element (58, 68) arranged on the support unit (12), a chute device (59, 69) that is adapted to be attached to the support unit (12) and to accommodate the transfer pipe (13, 14) such that the chute device (59, 69) supports the transfer pipe (13, 14) and takes up and transfers vertical and transverse forces from the transfer pipe (13, 14) to the support unit (12), a tie-in device (77, 79) that is connected to the spool piece (61, 71) and is adapted to be connected to a tie-in member (76, 78) on the support unit (12) such that tension loads are transferred from the transfer pipe (13, 14) to the support unit (12).
