| 161 | Underwater seafloor drilling rig | US11583562 | 2006-10-19 | US20080093082A1 | 2008-04-24 | Adel Sheshtawy |
| A subsea drilling system comprises a pressurized drilling capsule that is sealed against the subsea environment and houses equipment for manipulating a drillstring that extends through an opening in the drilling capsule to the exterior of the capsule. A drilling fluid handling assembly is contained within the drilling capsule that communicates drilling fluid through the drillstring and returns the drilling fluid to the water's surface via a drilling fluid conduit. A seafloor unit engages the seafloor and the drilling capsule to position the drilling capsule relative to the seafloor, and includes an opening for passing the drillstring into the seafloor. A pressurized transport unit is movable between the drilling capsule and a support vessel at or near the water's surface for delivering personnel and supplies to the drilling capsule. A method of drilling using the subsea drilling system is achieved by pressurizing a drilling capsule assembly and maintaining the drilling capsule assembly in a pressurized state suitable for human occupancy. The drilling capsule assembly is submerged by altering its buoyancy. The drilling capsule assembly is secured to the formation by drilling a pilot hole in the formation from within the drilling capsule assembly and by inserting a portion of the drilling capsule assembly into the pilot hole. A drillstring is delivered to the drilling capsule assembly, the drillstring including at least one length of 30-foot drillpipe. A bottomhole assembly is made up into the drillstring and rotated from within the drilling capsule to bore a hole in the formation. The drillstring is selectively removed from the hole and the drilling capsule assembly, wherein the drillstring remains assembled and includes at least one length of 30-foot drill pipe. | ||||||

| 163 | Drilling rig | US10513080 | 2003-04-29 | US20050109537A1 | 2005-05-26 | Laurence Ayling |
| An underwater drilling rig in modular form, which can be simply assembled underwater and in which standard tubulars and tubular assemblies are stored in a novel arrangement within containers and can be added to, and removed from, the string in the well bore, whilst there is continuous circulation of drilling fluid and also continuous segregation of drilling fluid from the seawater, additionally: with a simple means of accessing the tubulars and gripping them from inside in order to make up tool joint connection to the top drive sub, with a means to guide and centralise each tubular or tubular assembly on entering the well bore or when being returned to storage with a means to enable the top drive to snub with greatly reduced force and no risk of buckling the tubular, with a rig support vessel that, in the absence of a marine riser, drill string or drilling rig, is greatly reduced in size and can roam extensively to ride out bad weather, while the seabed rig continues to drill; lastly with the novel ability to control the mud pressure and flow both in and out of the well bore at seabed level, thus greatly improving downhole pressure strategy, ultimately the first system that can operate at water depths of 10,000 to 20,000 feet which is still beyond the current economic and technical ability of offshore drilling rigs. | ||||||
| 164 | Self-erecting rig | US10020367 | 2001-12-12 | US06675899B2 | 2004-01-13 | E. Alan Coats |
| A self-erecting rig is adapted for deployment on a platform and includes hydraulic jacks and rails. The rig structure is made up of stacked, interlocking modules having open areas pre-fitted with well equipment such as mud pumps, mud tanks, and power packs. The rails are disposed on a platform and guide the modules to the hydraulic jacks. Hydraulic jacks, also fixed onto the platform, are configured to releasably engage and elevate the modules. During deployment, the jacks engage a module and hoist it to a pre-determined height. While the engaged module is suspended, another module is slid immediately below. After the two modules interlock, the jacks repeat the process. | ||||||

| A multi-purpose drilling rig has a movable pipe support cradle which moves horizontally to transfer drill pipe from a storage area to the well being drilled, and vice versa. The cradle travels along a roof platform supported by load-bearing hydraulic lifting rams. Raising or lowering the lifting rams raises or lowers the roof platform, along with the drill pipe suspended from the cradle. Structural towers stabilize the lifting rams against buckling and lateral loads. Supplementary lifting capacity is provided cradle-mounted roof rams having pistons which may extend downward from the cradle, with the drill pipe suspended from a yoke interconnecting the roof ram pistons. For offshore drilling, a control system senses fluctuations in rig elevation due to wave action, and automatically adjusts extends or retracts the rams as required to maintain constant load on the drill bit. Also disclosed is a method of drilling which utilizes vertical and lateral movement of the cradle and top drive. | ||||||

| A spar platform is disclosed having a deck, a buoyant tank assembly supporting the deck, and a counterweight. A counterweight spacing structure connects the counterweight to the buoyant tank assembly. The buoyant tank assembly has a first buoyant section connected to the deck and a second buoyant section disposed beneath and axially vertically aligned with the first buoyant section. The second buoyant section has a substatially larger diameter than the first buoyant section and a buoyant section spacing structure connects the first and second buoyant sections in a manner providing a horizontally extending vertical gap therebetween. Another aspect of the invention is a method for reducing VIV in spar platform by providing a substantially open horizontally extending vertical gap in the cylindrical buoyant tank assembly between a first buoyant section and a second buoyant section. The first and second buoyant sections are vertically aligned and are selected to combine first and second buoyant sections of substantially different diameters. | ||||||
