Patent number: 5549417Abstract: Vortex-induced vibrations of unsupported segments of subsea pipelines are reduced by providing a shroud that can be lowered onto the subsea pipeline wherein the shroud creates turbulence that interferes with vortex shedding and thereby reduces the amplitude of vibrations are reduced. The preferred shroud comprises a plurality of rods supported in vertical planes along the sides of the pipeline. Installation can be performed without the use of divers.Type: GrantFiled: November 19, 1993Date of Patent: August 27, 1996Assignee: Shell Oil CompanyInventors: Gwo-Tarng Ju, Eric S. Goudy, Ray R. Ayers

Patent number: 5320175Abstract: A diverless and guidelineless method to connect two subsea flowlines by a jumper assembly is provided. Pivotable stabs and fluid connection means are provided on each end of the jumper assembly. The stabs mate into receptacles located on the subsea flowline connections. The flowline is preferably lowered vertically and hinged over while sequentially landing the two pivotable stabs into their respective stab receptacles.Type: GrantFiled: January 29, 1993Date of Patent: June 14, 1994Assignee: Shell Oil CompanyInventors: Paul B.

Patent number: 4974995Abstract: Pressure-triggering buoys are constructed of prebuckled pipe segments and attached to an offshore structure or pipeline under construction. The attached buoys move with the structure or newly added pipe segment toward the sea bottom, easing the descent. As the structure or segment of pipeline reaches a predetermined depth, the buoy attached thereto collapses, causing the structure or segment of pipeline to be heavier. In the instance of a pipeline, this collapse, in turn, causes the adjacent upper segment of pipeline to move lower, causing the next buoy to collapse, and so on.Type: GrantFiled: June 28, 1985Date of Patent: December 4, 1990Assignee: Shell Oil CompanyInventor: Ray R. Ayers

Patent number: 4869191Abstract: A method and apparatus are provided for launching a towable body from onboard a towing ship while the towing ship is underway. Inasmuch as the towable body has a tendency to swing from side to side due to motion of the towing ship as the towable body is being lowered into the water, stabilizing apparatus which is attached to the towable body is lowered into the water first, the stabilizing apparatus tending to damp the side to side movement of the towable body.Type: GrantFiled: July 21, 1983Date of Patent: September 26, 1989Assignee: Shell Oil CompanyInventor: Ray R. Ayers

Ayers
-
Patent number: 4724788Abstract: A method and apparatus are provided for towing and steering a seismic subarray from onboard a tow vessel. The outboard reach of the seismic subarray, relative to the vessel, is controlled by an adjustable bridle connected to the seismic subarray, and turning of the subarray in coordination with turning of the vessel is done using both the bridle and a rudder located at the rear of the seismic subarray.Type: GrantFiled: October 3, 1984Date of Patent: February 16, 1988Assignee: Shell Oil CompanyInventor: Ray R. Ayers
-
Patent number: 4709356Abstract: The positions of seismic subarrays are determined using special hydrophones in a streamer cable which listen for acoustic signals generated from each seismic subarray.Type: GrantFiled: November 22, 1985Date of Patent: November 24, 1987Assignee: Shell Oil CompanyInventor: Ray R. Ayers
-
Patent number: 4640645Abstract: An oil containment boom system of two parallel, spaced-apart booms, with the forward boom designed to permit splashover of oil, a low pressure area between the booms functioning to retain the splashover oil.Type: GrantFiled: September 23, 1985Date of Patent: February 3, 1987Assignee: Shell Oil CompanyInventors: Wayne F. Simpson, Ray R. Ayers, Robert W. Patterson
-
Patent number: 4621844Abstract: A connector for joining pipe ends is provided having heat expandable or contractable memory metal rods individually connecting a wedge ring and gripping wedge collet. Each ring and collet are in abutting relationship and coact to grip a pipe end.Type: GrantFiled: September 6, 1984Date of Patent: November 11, 1986Assignee: Shell Oil CompanyInventors: Robert M. Kipp, Ray R. Ayers
-
Patent number: 4602652Abstract: A pressure vessel is provided with a single use safety valve composed of a partially buckled, hollow chamber which is susceptible to further buckling at a preselected pressure. The chamber is mounted and elastomerically sealed in an opening in the vessel held in position by a support frame either interior to or exterior of the vessel.Type: GrantFiled: June 20, 1984Date of Patent: July 29, 1986Assignee: Shell Oil CompanyInventor: Ray R. Ayers
-
Patent number: 4573713Abstract: The present invention provides a pipeline connector which uses collected conical rings as a holding mechanism designed to penetrate a pipe surface as they are simultaneously flattened. Several rings are required to achieve the total required shear load transfer area. The penetrating rings preferably are separated by shorter, non-penetrating rings to increase the loading area, thus limiting the external pressure loading on the pipeline.Type: GrantFiled: November 22, 1982Date of Patent: March 4, 1986Assignee: Shell Oil CompanyInventors: Robert M. Kipp, Ray R. Ayers
-
Patent number: 4563108Abstract: A pressure-actuated release mechanism is assembled using a prebuckled pipe segment as a pressure-triggering mechanism. The trigger mechanism is employed to attach buoys to an offshore structure or pipeline under construction. The attached buoys move with the structure or newly added pipe string toward the sea bottom, easing the descent. As a preselected external pressure is sensed, the buckle in the pipe segment propagates and the trigger mechanism actuates, releasing buoys from the structure or pipeline as each buoy in turn reaches the same depth or pressure.Type: GrantFiled: May 15, 1985Date of Patent: January 7, 1986Assignee: Shell Oil CompanyInventor: Ray R. Ayers

Patent number: 4556341Abstract: A stable offshore platform for surface or undersea work is provided by connecting a semisubmersible trailer unit with a workboat. Preferably, two columns of the trailer are joined by a beam member or truss, and this assembly is linked to the workboat via a truss-like trailer tongue with a ball swivel joint. When in transit, the semisubmersible unit is deballasted to a shallow draft condition and towed by the workboat.Type: GrantFiled: February 19, 1985Date of Patent: December 3, 1985Assignee: Shell Oil CompanyInventor: Ray R. Ayers
-
Patent number: 4554072Abstract: An offshore oil spill cleanup system is provided which includes a barge arranged downstream of an oil spill to split the flow of oil to either side of the barge, two booms, each arranged on opposite sides of the barge to catch the diverted oil, and stationary skimmers working in the sheltered area behind the barge and within the booms to remove oil from the boom area to the barge. Diversionary booms are arranged upstream of the barge and chase skimming systems are located downstream of the barge and are functionable to move independently of the barge and recover any oil getting past the booms attached to the barge.Type: GrantFiled: September 27, 1984Date of Patent: November 19, 1985Assignee: Shell Oil CompanyInventor: Ray R. Ayers
-
