Floating Platform with an Articulating Keel Skirt

摘要

The present disclosure provides in at least one embodiment a rotatable keel skirt assembly on a rectangular-shaped keel pontoon. The rectangular-shaped keel pontoon reduces the maximum hull width by a significant percentage compared to a circular-shaped keel pontoon while maintaining the same hull motion performance. The rotatable keel skirt assembly allows the size of the pontoon to define the width of the hull during some fabrication phases of the platform, rather than the additional width of the keel skirt assembly. Thus, the outreach of the crane and other equipment can be effectively used as if the keel skirt assembly was not present. After fabrication, the hull can be moved away from the quayside and the keel skirt assembly can be rotated into position for service. Various systems and methods are disclosed for articulating the keel skirt assembly about the hull.

主权项

1. A floating offshore platform for hydrocarbon storage, production, and/or offloading, comprising:
a hull; a pontoon coupled to the hull; and at least one keel skirt assembly having at least one keel skirt and a support structure coupled with the keel skirt, the keel shirt assembly being coupled with the peripheral surface of the pontoon and configured to be extended and lowered from a stored position above the pontoon into a deployed position adjacent to the pontoon and extended outward from the pontoon.
