BEASY AT NACE CORROSION 2012

SALT LAKE CITY

BEASY will once again be attending the annual NACE Corrosion Conference, which this year is being held in Salt Lake City, Utah, between 11th and 15th March.

 

We will be active in both the conference program and exhibit hall showing our corrosion modeling services and software.
 

 

To receive a free one-day VIP exhibit pass, or if you would like to set up a meeting to discuss any aspect of BEASY's modeling or software services, please contact Alison Horn
BEASY Exhibit

 

We will be in the exhibit hall on booth 711 and invite you to visit us to catch up on the latest corrosion modeling technology and applications, discuss potential modeling projects or just say hello! Both Bob Adey and Tim Froome will be attending and would welcome the opportunity to meet you. 

 

Technical Program

 

BEASY are contributing to the Technical Program by presenting papers on some recent projects:

Using Modeling to Interpret and Expand CP Survey Data

 

Robert A Adey, Cristina Peratta, and John Baynham, BEASY

 

A case study will be presented in which computer modeling is used to evaluate the data obtained from a survey of the structure. By further processing that data within the model, comprehensive visualisation is provided of the distribution of protection potentials across the full extent of all the structures in the model, together with clear representation of the consumption levels (current and projected) for each anode.

 

The owner of the asset is thereby able to secure considerable additional advantage from the survey, which they then feed back into their CP strategies and the specification of subsequent surveys.

 

General Consideration About Current Distribution And Potential Attenuation Based On Storage Tank Bottom Modeling Study

 

Jean Vittonato,TOTAL E&P CONGO, Robert A Adey, John Baynham, BEASY

 

In this investigation, two CP system configurations were applied to a storage tank bottom and studied with 3D modeling. The first variant incorporated an anodic grid system installed beneath the tank bottom and a membrane below that. The second variant had no membrane installed beneath the tank and the anodes were located around the periphery of the tank. The paper investigates the role of the resistivity of the sand cushion below the tank and the surrounding environment and draws conclusions valuable for the design of Tank Base CP systems.

  

Jacket SACP System Design And Optimization Using Simulation

 

John Baynham, Tim Froome, Robert A Adey, BEASY

 

Careful design of sacrificial anode cathodic protection systems in order to achieve broadly uniform anodeOptimising a SACP System mass loss rates is desirable, as otherwise certain anodes will become fully consumed before others, creating a risk that a retrofit system may need to be installed earlier than would otherwise be necessary, with all its associated costs.

 

However, for many structures, the complexity of changes in the distribution of current demand over time (influenced by, for example, ongoing degradation of coated areas) makes this a very difficult process.

 

The paper illustrates how computer modeling can meet this challenge, explaining the design and optimization process as applied to a jacket structure.

Training
  

Hands-on courses which provide training to maximize the benefits from BEASY's corrosion software, will be held in the UK and US as follows:

  

* UK Corrosion & CP course - March 21st to 23rd 2012

* US Corrosion & CP course - May 8th-10th 2012
