Abstract
The invention relates to a structure for sea-bed exploitation allowing the various functions inherent in such exploitation to be performed, such as for example production, reconditioning and maintenance of underwater well-heads, wherein said structure comprises at least one articulated column performing one or several said functions. In particular, each well-head is accessible through servicing means, such as a movable tool secured to and jointly movable with a support pivotally connected to a carriage movable along guide-rails mounted either within or outside the horizontal apparent contour of the body of the column.
Claims19
A structure for sea-bed exploitation allowing various functions of such exploitation to be performed in connection with well-heads clustered into at least one group in the sea-bed, such, for example, as production, reconditioning and maintenance of said underwater well-heads, and water or gas injection into the productive layers of the sea-bed, said structure comprising:
- at least one articulated emergent column having a body with a submerged and an emerging portion, said column being adapted to perform at least one of said functions and having associated therewith intervention or servicing means, such as a movable tool, adapted to be vertically alignable over to provide access to each of said well-heads, said intervention or servicing means being secured to and jointly movable with a support, said support being pivotally connected to a carriage, said carriage being movably mounted along guide-rails mounted adjacent to the horizontal apparent contour of the body of the said column.
