Abstract
A subsea steep wave lock and guide mechanism (1) for elongated articles (2) such as cables, pipes and umbilicals provides a substantially horizontal inlet (6) for the article at seabed level and a substantially vertical flexible article outlet (4) leading to the steep wave. The lock and guide mechanism (1) includes a number of lockable/releasable gates (20-24) for restricting and defining allowable movements of the article in the horizontal as well as in the vertical direction.
