Abstract: Method for connecting a termination hub (201a) to a porch hub (101a) at a subsea location by using a subsea fluid connection system (1). The connection system (1) comprises a porch part (100) with the porch hub (101a), a termination part (200) with the termination hub, and a connector (300). The method comprises a) landing the termination part (200) on the porch part (100) at a subsea location; b) moving the termination hub (201a) of the termination part (200) into alignment with the porch hub (101a) of the porch part (100); c) with the connector (300), connecting the termination hub (201a) to the porch hub (101a). The method further comprises d) after step c), actuating a moment arrestor arrangement (400), thereby further arresting the termination part (200) to the porch part (100). A subsea fluid connection system is also disclosed.

Abstract: A subsea horizontal tie-in system comprising a porch part (100) with a porch hub (101a), a termination part (200) with a termination hub (201a). The termination part is configured to land on the porch part. The tie-in system further has an alignment system to align the porch hub (101a) and the termination hub (201a) during movement of the termination hub towards the porch hub in a landed state. The alignment system comprises guide arrangements (A1, A2, B1, B2) having porch guide faces (113p, 113q, 113r) on the porch part and termination guide faces (213p, 213q, 213r) on the termination part. The porch guide faces and termination guide faces are configured to slide against each other during said movement. The porch part (100) comprises a base plate (103) on which the porch guide faces are arranged.
