Patent ID: 8585325

Claim:
A cantilever system for a rig, comprising: a hull; a beam movably coupled to the hull, wherein a first end of the beam is extendable over an edge of the hull while a second end of the beam is positioned on the hull; a passive hold-down member that is spaced from a support member to support the beam, wherein the passive hold-down member is positioned at a predetermined distance from the support member such that when the beam is fully extended, a maximum load that the beam supports is increased but a maximum reach of the beam is reduced, and wherein the beam is secured to the hull by a plate member of the passive hold-down member that extends below a surface of the hull; and an extension member coupled to the second end of the beam to increase the length of the beam, wherein when the beam is fully extended with the extension member, the maximum reach of the beam is increased.
