Title: Apparatus for storing a flexible elongated member, such as a flexible drill column

Abstract: The present invention relates to an apparatus or device for storing elongated flexible elements, such as drilling pipe, in a coiled form. This apparatus includes an inner cylindrical framework supported about a vertical axis, an outer cylindrical framework concentrically separated from the inner framework and connected thereto by an annular base plate closing the bottom of the apparatus. The space between the inner and outer frameworks is open at the top to receive the elongated elements, and the annular base plate is formed of a plurality of annular sector elements connected together in such a manner as to allow a vertical displacement of respective adjacent elements with respect to one another. Various means for connecting adjacent elements are provided. Moreover, various driving and supporting members are provided for rotating the apparatus about the vertical axis.
