In this last Newsletter of 2011, in addition to the latest BEASY Corrosion news, we review some of the year's most popular downloaded news items.
Seasons greetings from the BEASY team |
 Tim Froome recently presented "The Role of Computer Modelling In the Design, Optimisation and Operation of CP Systems" at the 1st NACE Jubail Industrial Forum. He described three case studies on how computer modelling can be used to ensure the integrity, reliability and operation of onshore and offshore structures and plant.

Optimising a SACP System using Simulation, to Achieve Uniform Anode Life and Protection Potential
At the Eurocorr conference in Stockholm, Sweden,Tim Froome presented a paper based on some recent engineering services projects where modelling has been used to optimise the cathodic protection system protecting Oil & Gas Offshore structures.
The optimisation process first involves simulation of an initial SACP system design. Performance of the design is assessed against criteria which may include anode mass loss rate, most positive allowed potential and remaining anode mass, not only at start of life,but also throughout the design life of the structure. The results of previous assessments are used to guide the selection of the next trial SACP system design, which usually involves changing the number, position or size of anodes.

Predicting The Risk Of Galvanic Corrosion in Structures
BEASY presented a paper at the DOD Corrosion Conference on a Modelling Approach for Galvanic Corrosion Protection of Multi-material Aircraft Structures. The paper described developments carried out with co authors EADS and Airbus into developing tools to quickly assess the risk to components and structures of corrosion and the effectiveness of surface protection systems. Galvanic Corrosion is important as it occurs whenever dissimilar metals or certain types of composites (eg carbon based) are located close to each other.
The paper gave an overview of the development and experimental validation of a computational model for simulating galvanic corrosion in specific application case scenarios appearing in an aircraft environment. The focus of the study is thin electrolyte conditions that could occur in the upper part of an aircraft structure. An experimental set-up has been established for validation of the computational results. The validation approach is explained and the results obtained are presented. Good agreement has been obtained between observed and simulated data. The model can be applied to different multi-material combinations relevant non only for aircraft structures but also to assess the risk of corrosion in a wide variety of structures.

Corrosion Related Signature Prediction
Tom Curtin from BEASY's office in Massachusetts presented a paper at the MARELEC conference entitled "Evaluating effects of roll on corrosion-related UEP using simulation". The paper describes some recent developments in BEASY's Signature Management software which is used to predict the corrosion related electric and magnetic signatures of Naval vessels.

| Integrating Corrosion Modelling into the Design Cycle
In the past, engineers with responsibility for corrosion aspects of a design have often been faced with the need to adopt a strategy of 'Design it, Build it, Start testing', and then find what works and what doesn't.
However, advances in computer modelling mean that simulation studies are increasingly being embedded in the design phase to evaluate corrosion behaviour and perform parametric studies to assist the optimisation of the solution selected. Whilst modelling will never eliminate the need for monitoring structures, it can provide valuable inputs to the validation of the design; enable a substantial reduction in the risk of failure and aid engineers in the identification of critical areas where subsequent monitoring can be effectively focused.

 Modelling of Impressed Current Cathodic Protection Anode Arrangements for Storage Tank Bottoms
Bob Adey presented a paper at the 31st Computers and Information in Engineering Conference in Washington DC.
In a special session on Advances in Understanding and Modelling of Corrosion organised by Virginia DeGiorgi, Bob described some recent work on the optimisation of storage tank bottom ICCP systems.
