Millheim, Keith K. |
A dual-BOP or multi-BOP self-standing riser configuration is disclosed, including at least a riser or another similarly fixed tubular structure disposed in communication with an associated drilling vessel and a subsurface well. The system supplements the traditional mud-line level BOP with one or more additional near-surface BOPs, which are tensioned using an adjustable buoyancy chamber rather than by means of a vessel-born tensioning device. |

A subsea well completion system, and components of such a system, are disclosed for handling marine well fluids from multiple subsea wells. The system includes a fluid-tight work enclosure hull containing manifold means, the hull having a plurality of radially-disposed lateral penetration means extending therethrough, the penetration means being operatively connected to the manifold means; and a base template having means for securing the template to the marine floor in a substantially horizontal position and having a lower support structure for supporting the work enclosure hull, the template further having an upper guidance structure comprising a plurality of substantially vertical guide members mounted in spaced radial array, each guide member extending inwardly toward the center of the template, forming an opening at the central portion of the template for receiving the work enclosure hull, a portion of the upper peripheral surface of each guide member sloping downwardly toward the opening for guiding the hull as it is lowered during installation of the hull onto the template. A method of establishing production capability from multiple subsea wellheads on a base template secured to the marine floor is also disclosed employing the aforecited system components. |

Burton Hoster Mason |
A work arm system for a submergible chamber wherein a plurality of work arms are rotatably mounted to the chamber and are retractably extensible, so as to provide a plurality of tools for work at a subsea station, such as an offshore wellhead station. One arm is provided with tool mounts at opposite ends, both ends being retractably extensible so that each end may alternatively be disposed to the subsea station. The present work arm system permits several work functions to be performed without resurfacing of the chamber. |
