Patent number: 9182081Abstract: A method and system for evaluating the sample coverage of ultrasonic or radiography (UT/RT) measurements of pipeline wall thickness for statistical validity. A data library contains distributions of in-line inspection (ILI) measurements for other pipelines, calibrated to correspond to UT/RT measurements as needed. The data library for these ILI-measured pipelines also includes statistics generated from Monte Carlo simulation, by way of which various sample coverage levels sample the ILI measurements, for determining whether a measurement exceeds a given threshold or meets another premise related to determining the extreme wall loss measurement for the pipeline. A pipeline with sampled UT/RT measurements is used to identify one or more ILI-measured pipeline datasets that are most similar, and the statistics from those most similar pipeline datasets determine whether the sample coverage of the UT/RT measurements is sufficient to draw conclusions about the extreme value of wall loss in the sampled pipeline.Type: GrantFiled: June 30, 2008Date of Patent: November 10, 2015Assignees: BP Corporation North America Inc., BP Exploration Operating Company LimitedInventors: Eric R.

Publication number: 20130304680Abstract: In accordance with aspects of the present disclosure, a computer-implemented method for predicting a material deterioration of a coupon inserted into the well line system is disclosed. The computer-implemented method can be stored on a tangible and non-transitory computer readable medium and arranged to be executed by one or more processors that cause the one or more processors to receive data related to the well line system; determine one or more predictors of material deterioration of a coupon based on the data; and predict a material deterioration of the coupon inserted into the well line system based on a mathematical model of the material deterioration using the one or more predictors.Type: ApplicationFiled: May 10, 2012Publication date: November 14, 2013Applicants: BP EXPLORATION OPERATING COMPANY LIMITED, BP CORPORATION NORTH AMERICA INC.Inventors: Richard S.

Publication number: 20130304438Abstract: Methods and systems for using survival modeling methods with pipeline inspection data to determine causal factors for corrosion under insulation comprise determining a first corrosion condition of a pipeline joint at a first time; determining a second corrosion condition of the pipeline joint at a second, subsequent time; determining joint attributes, pipeline attributes, and location attributes associated with the pipeline joint; and repeating the process for a plurality of pipeline joints in one or more pipelines. This information is fed into a multiple regression and survival analysis process that determines regression coefficients reflecting the estimated degrees to which various factors contribute to corrosion under insulation. The survival analysis also determines one or more survival models capable of predicting when a given pipeline joint is likely to transition from a first corrosion state to a different second corrosion state, given values for its various attributes.Type: ApplicationFiled: May 9, 2012Publication date: November 14, 2013Applicants: BP EXPLORATION OPERATING COMPANY LIMITED, BP CORPORATION NORTH AMERICA INC.Inventors: Richard S.

Patent number: 8249264Abstract: Reverberation parameters for one or more positions of interest are derived from graphics data used for displaying a computer-generated environment. For each position of interest for which reverberation parameters are desired, environmental parameters including distances and the hardness of features in a range of interest and at points on cubemap faces are automatically determined from the graphics data. The environmental parameters are stored with the graphics data and associated with each position of interest. Upon rendering of the computer-generated environment, reverberation property set values usable by a reverberation engine are calculated or interpolated between predetermined values according to the environmental parameters.Type: GrantFiled: September 17, 2009Date of Patent: August 21, 2012Assignee: Microsoft CorporationInventors: Richard S. Bailey, Barry Brumitt

Patent number: 8167191Abstract: A multi-layer seal arrangement includes a dissolution barrier between a braze alloy and a ceramic component. The inventive seal is useful for joining a ceramic component to another ceramic component or a metal component, for example. In one example, the braze comprises a gold alloy and the dissolution barrier comprises a layer of alumina on the order of 2-3 microns thick. A titanium wetting layer is provided between the alumina layer and the alloy. A metallization layer provided between the dissolution barrier and the ceramic component in one example comprises a layer of gold between two thin layers of titanium. In one particular example, a platinum mesh is included with the gold of the braze alloy to control braze flow during the brazing operation.Type: GrantFiled: June 21, 2011Date of Patent: May 1, 2012Assignee: Hamilton Sundstrand CorporationInventors: Sunil G. Warrier, Richard S. Bailey, Willard H. Sutton

Patent number: 7941282Abstract: A method and system for estimating the worst case corrosion in a pipeline for which pipeline wall thickness measurements are limited to sampled ultrasonic or radiography (UT/RT) measurements. A data library contains distributions of in-line inspection (IL) measurements for other pipelines, calibrated to correspond to UT/RT measurements as needed. These ILI datasets are randomly sampled multiple times, to obtain multiple sample sets from each ILI dataset. Candidate statistical distributions are evaluated for each sample set to determine which of the candidate statistical distributions most accurately estimates the worst case corrosion measured by ILI. A discriminant function is then derived from sample statistics and pipeline descriptors associated with the sample sets, along with the best candidate statistical distribution for that sample set.Type: GrantFiled: January 7, 2009Date of Patent: May 10, 2011Assignees: BP Exploration Operating Company Limited, BP Corporation North America Inc.Inventors: Eric R Ziegel, Richard S.
