Predicting Ballast Tank Corrosion Through Computer Modeling BEASY is featured in the September 2013 issue of Materials Performance (MP) which is the world's largest circulation journal dedicated exclusively to corrosion prevention and control.
The article discusses some recent projects using computer modelling to predict the performance of ballast tank corrosion control systems.
In recent years BEASY has seen a significant increase in its corrosion modelling services business and to meet this demand a number of new members of staff have joined the company this year.

The starting point for BEASY modelling projects is working with the client to develop an agreed set of objectives and to define the methodology and the deliverables. The BEASY simulation provides the client's CP responsible authorities with a thorough understanding of the behaviour of the structure, and its response to alternative CP systems/parameter studies to assist in the selection of the final CP design solution.
Projects have included:
Water lift caissons, where modelling has embraced the effects of different metals (eg lift column and pump), the effects of geometries on current flow, and the impact of water flow rates on current density requirements
Buried storage tank farms (eg LNG), where modelling has identified the protection achieved incorporating the influences of reinforced concrete footings (for pipe racks etc), and providing input to aid selection of appropriate reference electrode locations
FPSO and associated structures, where modelling has been used to assess interference effects between the CP systems, and for a number of sub-structures to determine the distribution of protection resulting from restrictions to current flow imposed by geometry
Well casings, assessing the impact of interference effects from other structures
Pipeline arrangements, where modelling has assessed complex attenuation effects
Offshore jacket structures, where modelling has been used to achieve optimal distribution of sacrificial anodes.
Guy Bishop presented a paper entitled "Recent Signature Modelling Studies To Predict The Impact Of Hull Openings And ICCP System Anode Failure" at the recent MARELEC 2013 conference in Hamburg, Germany.
The study used computer modelling to assess the robustness and sensitivity of the vessel ICCP system to the impact of anode failures, damage, coating degradation, hull opening and appendages etc. Of particular interest were the corrosion related electric and magnetic signatures. The study used the latest release of the BEASY Corrosion Defence modelling software. The results demonstrate how a computational modelling approach is one of the most effective tools for the design of corrosion control systems and optimization of ship electric and magnetic signatures.

Training
Courses are held regularly at BEASY's offices near Southampton in the UK, and at Billerica, Massachusetts in the USA.
Courses are also held at customers' sites and can be tailored to meet the specific needs of the client.
