Abstract
The invention described herein teaches that one drilling barge can be employed in two different areas. The standard drilling practice requires two vessels to perform the same work as one drilling barge invention. Standard drilling rigs require that one unit will drill well locations in water depths of 8′-18′. A second drilling unit must be provided to drill in water depths of 18′-60′. As a result of this invention, water depths of 8′-60′ can be provided by use of the one vessel employing the novel stabilization system. The service area's coverage is increased greatly by use of the invention thereby creating excellent cost reduction and improved drilling procedures in remote and harsh drilling areas. The invention's cost is slightly more than the standard drilling barge however; coverage of the service area can be 500% greater than the standard vessel's coverage.
