Two units have been constructed so far, both by Hyundai Heavy Industries, with contract prices (including mobilization) in the $310 million range. The vessels are harsh-weather, deep water rigs (8,000-10,000 feet).

Design

The RBS-8D design consists of an 4-column, dual pontoon unit. The columns are distinctly arched inward to the rig deck, with prominent shoulders, narrowing near the top. The pontoons are blunt with lengths comparable to the length of the deck. The drill rig is located about the centre of the rig deck. Between the columns, there are smaller lateral braces aligned to the underside of the pontoons.
