BEASY CP Modelling Showcases at NACE Corrosion 2011 in Houston

 BEASY at NACE 2011

 

 

 

 

 

 

 

 

BEASY participated in a very busy NACE Corrosion Conference in Houston, Texas, recently and was active in both the conference programme and exhibition hall, highlighting its corrosion modelling services and software.


 

There were a number of papers presented during the Technical Programme which featured BEASY modelling in applications.  These included: 

 

* CP of Underground Pipe Work in an Oil & Gas Transmission Station

* CP Protection of a PCCP Pipeline

* Two papers about CP Retrofits of Offshore Structures

* CP of Reinforced Concrete in a Dock Remedial Project
  
Further information on these applications is available to download as follows:

Oil & Gas CP Protection Scheme

Potential distribution for the case of two

75m deep-wells anodes 

In oil and gas transmission stations there are all kinds of buried pipelines, tank bottoms, equipment bases and grounding.  These would consume relatively large current and also cause many problems such as interference and shielding.  Thus, it is very difficult to design anode ground beds in oil and gas transmission stations.  In this work numerical simulation is applied to determine the optimal cathodic protection scheme in oil and gas transmission stations.

Application of Computational Modeling to Predict the Effectiveness of CP on a PCCP Transmission Pipeline
Robert A. Adey, Andres Peratta and John M W Baynham, CM BEASY Ltd
  

The paper describes a computer modeling study which was designed to determine the protection provided by a CP system, to evaluate different design options, and to optimize the design.

Cathodic Protection Retrofit of a Spar Platform
David K. Flanery, Deepwater Corrosion Services, Inc
  

The spar required a life extension significantly in excess of the original 15-year service life, including the CP system.  At the request of the operator, a 15-year life extension impressed current cathodic protection (ICCP) system was designed, supplied and commisioned.

Optimization of Retrofit Cathodic Protection (CP) Systems Using Computational Modeling by Evaluating Performance of Remnant and Retrofit CP Systems, Taking into account Long-Term Polarization Effects
Anil K. Jain, NACE Corrosion Specialist, Dubai Petroleum, Cristina Peratta, John M.W Baynham, Robert A. Adey, CM BEASY Ltd
  BEASY Corrosion Software

The paper presents a case where modelling has been applied to a jacket structure, using "long-term" polarization curves to represent accumulation of calcareous deposits.  Hence, the key benefits achieved are: retrofit requirement reduction, significant cost savings, better CP current distribution despite reduction in number of anodes, maximized life.
