Established Technology
in a New Configuration


Figure 1 Illustrates a Versabuoy platform configured for full API rig platform drilling with a 3x3 central moon pool supporting up to nine surface trees, and top tensioned risers. In this depiction the conventional open truss configured topsides is supported by four independent buoys, each buoy connected to the topsides by an articulating connection. This connection decouples the buoy pitch and roll motions from the topsides and from each other. Each buoy is intrinsically stable and has a GM value typically in the range of 25 to 50 feet. The buoys have no connections between them below the water line. The taut leg mooring lines and catenary risers attach directly to the deck, facilitating installation and in-service inspection and maintenance as required.
