duct installation device on a water extension, floating installation structure and method of installing a duct on a water extension

摘要

A device for laying a pipe in an expanse of water includes a tower (30) intended to protrude along a tower axis (B-B′) in a floating laying structure (10), and assemblies (34A, 34B) for gripping and moving the pipe (12) in order to guide the movement of the pipe (12) towards the expanse of water (11) along a laying axis (C-C′). Each gripping and moving assembly (34A, 34B) is borne by the tower (30). The tower (30) is formed by a barrel (32) extending along the tower axis (B-B′), each gripping assembly transversely protruding from the barrel (32) relative to the tower axis (B-B′).
