Title:
SUBSEA CONNECTING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2012/098369
Kind Code:
A3
Abstract:
A method and connecting apparatus for attaching a pipeline termination assembly (1) to a subsea structure (5) are described. The pipeline termination assembly (1) has a pivot axis member (3a, 3b) and the subsea structure (5) has one or more capture slots (9a, 9b, 10a, 10b) to receive it. The pivot axis member (3a, 3b) is captured in the capture slot (9a, 9b, 10a, 10b), the slot allowing vertical movement of the pipeline termination assembly (1). The pipeline termination assembly (1) is rotated about the pivot axis to assume a horizontal position. In the horizontal position, the capture slot (9a, 9b, 10a, 10b) permits horizontal movement of the pipeline termination assembly. A capture device (6) mounted on the subsea structure (5) provides said capture slots. At least a part of the capture device (6) is moved with respect to the subsea structure (5) to retain the pivot axis member (3a, 3b) in the capture slot (9a, 9b, 10a, 10b).
