Patent number: 9657563Abstract: A system for communicating between a downhole tool and a surface location. The system may include a downhole tool disposed within a subsea riser. The downhole tool may include a device that actuates between first and second positions. An internal transducer may be coupled to the downhole tool and transmit a signal indicative of the position of the device. An external transducer may be positioned on an exterior of a riser. The external transducer may receive the signal from the internal transducer through the riser. A transponder may be positioned on an exterior of the riser and coupled to the external transducer.

Patent number: 9534453Abstract: An intervention system and method for control of seabed equipment, including a control umbilical connected to a support vessel or rig via a surface winch; a tether connected to underwater seabed equipment; and an umbilical management system unit coupled between the tether and the control umbilical to couple the support vessel or rig to the seabed equipment. The control umbilical and the tether via the umbilical management system unit provide a communications channel for communicating media, including data, electrical power, hydraulic power and/or chemical treatment fluid, from the support vessel or rig to the seabed equipment. The umbilical management system unit allows for easy deployment and management of the control umbilical and tether and can reel in or pay out the tether and/or the control umbilical under remote control or autonomously.Type: GrantFiled: August 12, 2009Date of Patent: January 3, 2017Assignee: OneSubsea IP UK LimitedInventors: Jonathan Machin, Jean-Bernard Blamengin, Peter Nellessen

Patent number: 9528328Abstract: A tensions compensator assembly for a slip type joint in an offshore work string. The assembly includes a chamber at the joint which is constructed in a manner to offset or minimize a pressure differential in a production channel that runs through the work string. Thus, potentially very high pressures running through the string are less apt to prematurely force actuation and expansiveness of the slip joint. Rather, the expansive movement of the joint is more properly responsive to heave, changes in offshore platform elevation and other outside forces of structural concern.Type: GrantFiled: November 8, 2012Date of Patent: December 27, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Gary L. Rytlewski, Laure Mandrou, Peter Nellessen, Jr.

Patent number: 9488199Abstract: A subsea actuator comprising a plurality of chambers and at least three pressure levels, including an ambient pressure (medium), a substantially higher than ambient pressure (high), and an at or near surface atmospheric pressure or at a partial or full vacuum (low) to achieve a precise control of the actuator's closing force, speed, and stroke/position. The actuator enables full operations in emergency situations via manual or ROV operations; and can be operated (one way) to extend without supplied fluids in the event of high pressure failure emergency.Type: GrantFiled: June 27, 2014Date of Patent: November 8, 2016Inventor: Peter Nellessen

Patent number: 8978766Abstract: A temperature compensated accumulator and method for use thereof downhole in a well. The accumulator may include a housing with separate bulkhead and piston assemblies. Thus, one assembly may include a hydraulic fluid chamber separated from a gas precharge pressure chamber by a piston and the other assembly may include an ambient pressure chamber separated from an atmospheric chamber by another piston. Additionally a pressure relief and check valve assembly may be located at a pressure relief chamber between the other assembly sections. Thus, venting to or from the gas precharge pressure chamber may take place upon exposure to a predetermined decreased or elevated temperature so as to maintain a substantially constant precharge level for the accumulator, for example, in spite of dramatic changes in downhole temperatures.Type: GrantFiled: September 13, 2011Date of Patent: March 17, 2015Assignee: Schlumberger Technology CorporationInventors: Peter Nellessen, Jr., Quangen Du
