Method for connecting a conduit to a subsea structure, and a device for use in connecting a conduit end to a subsea structure

Abstract

The invention relates to a method for connecting a conduit (5) to a subsea structure (1), which comprises laying the conduit on the sea floor, with a conduit end (8) in the area close to the subsea structure. The method is characterized in that the conduit end is gripped by a ROV (9) with a gripping manipulator (10), that ROV (9) with the gripped conduit end (8) is advanced to the subsea structure (1), that the conduit end is introduced like a piston in a suitable receiving member (2) in the subsea structure, and that a negative pressure is provided in the receiving member so that conduit end (8) is sucked into the receiving member (2). The invention also relates to a device for use in connecting a conduit end (8) to a subsea structure (1). Conduit end (8) is advanced from the side of subsea structure (1) into a receiving member (2) of the subsea structure and is secured there. Receiving member (2) and conduit end (8) are mutually adapted so that conduit end (8) can move like a piston in receiving member (2). The receiving member has a connecting sleeve which is accessible from outside for connection to a source of negative pressure.
