Apparatus and method of laying an elongate article from a vessel

摘要

An apparatus for feeding an elongate article (6) from a floating vessel and suspending a first portion (6a) of the elongate article in a body of water below the vessel, comprises a cylindrical body (10) rotatably supported on the vessel and driving means (85, 86) for controlling the rotation of the cylindrical body. The cylindrical body (10) further comprises a spooling-on region (P) and a spooling-off region (U) for the elongate article, and a cylindrical contacting surface (18) for interaction with at least a portion of the elongate article (6); the contacting surface (18) being configured so as to support the first portion (6a).
