ABSTRACT:
A semi-submersible offshore structure for offshore operations. In an embodiment, the structure comprises a buoyant hull. The hull comprises a first elongate horizontal pontoon having a longitudinal axis, a first end, and a second end. The pontoon includes a first node disposed at the first end of the pontoon, a second node disposed at the second end of the pontoon, and an intermediate section extending axially from the first node to the second node. Moreover, the first node has a width W1, the second node has a width W2, and the intermediate section has a width W3measured perpendicular to the longitudinal axis in bottom view. The width W3varies moving axially from the first node to the second node.
