PlantR&A - A New Product Release of At Work Rio Solutions

August 2019

The Design Phase of a project, mainly the Conceptual Design Phase is of key importance to incorporate reliable technology tools that will add value to the design while addressing and mitigating risks not normally covered in this phase. Project Sponsors and stakeholders will be more convinced of the feasibility of projects as we submit then a comprehensive and sustained methodology that takes care of the uncertainties of a project at the conceptual design phase where all necessary investments or improvements will be included in the project budget without to postpone solutions that might destroy project value and reduce its profitability.

Keeping in mind this principle, At Work Rio Solutions Ltda. is developing technological tools that incorporate this methodology.

PlantR&A is a new web application, developed by At Work Rio and now released to the market, that performs Availability and Reliability analysis of an industrial plant, e.g.: gas pipeline, compressor station, natural gas processing plant, and others industrial plants onshore or offshore, using Monte Carlo Simulation technology. Provides users with resources to model and run projects to identify the level of reliability and availability of a project, to identify sensitive components and to improve the results by adding redundancy or replacing components with a higher level of reliability and availability.

We encourage readers to provide us with your comments and questions and we will be more than happy to provide you with additional information and clarifications. See original article posted on LinkedIn.

At Work Rio has signed an agreement with Houston based Siemens Energy Inc. for GasPipelineDesign Suite

February 2018

“At Work Rio Solutions is very proud to announce that we have signed an agreement with Siemens Energy, Inc., based in Houston, for their use of the mobile application GasPipelineDesign Suite v6.0.

This is a result of a joint work between Siemens and At Work Rio along two and a half months for trial testing the application with some examples of big pipelines as the Alliance Pipeline that operates with very high pressure, transporting rich gas from Canada down to Chicago, USA and the Republican Gas Pipeline in Texas.

We have modelled Siemens gas turbines to identify how accurate GasPipelineDesign Suite does the modelling and to identify the best technical and economical fit for Siemens equipment for a potential capacity expansion project.”

"Siemens extensively tested At Work Rio Solution’s GasPipelineDesign Suite while developing collaborative solutions with customers’ gas pipeline projects. Results were used to select Siemens gas turbines and compressors that are optimally sized for the application. The program’s features, speed, user interface and accurate results are quite impressive. Siemens’ high quality standards are fully addressed."

Thomas Diedrich, Head of Proposals, Americas, Siemens Energy Inc., Power and Gas Division. - February 2018.

Odebrecht Engineering & Construction International México has signed and agreement with At Work Rio

March 2017

This year of 2017, At Work Rio has signed an Agreement with Odebrecht Engineering & Construction International México to use the application GasPipelineDesign Suite. At Work Rio is very proud of this new achievement and we are fully committed to address Odebrecht and other customer’s needs.

"Odebrecht issued the following statement: “We are very pleased with GasPipelineDesign software that allows us to perform case studies during front end planning process. Its web based user-friendly interface enables us to access from anywhere with an internet connection, and simulate different scenarios with just a few clicks, which in the end is aligned with our commitment in satisfying our client’s needs through innovative solutions."
