The i-Pad based software of Intertrac Vision has been formulated using 3.5 billion datasets and 2.5 terabytes of historical coatings performance data collated by AkzoNobel over more than four decades. This unique information source enables ‘what-if’ scenarios comparing the relative costs and benefits of different hull coating choices.
The Intertrac Vision software divides the world’s oceans and coastal waters into 64 ‘large marine ecosystems’, each with specific characteristics relating to salinity, temperature, thermal range, seasonality, pH value and overall fouling risk. By integrating this data with a ship’s operating profile – information available from the Automatic Identification System (AIS) in the public domain – a complete fouling risk profile can be established for an individual ship in advance of its five-year docking cycle.
The software also enables more detailed predictive analysis to be carried out. For example, is it more effective to spot-blast and repair at a ship’s drydocking, or to invest more by undertaking a full hull blast and applying a completely new hull coating scheme?
Until now, there has been no scientific means of calculating the likely future performance of these two options, Hindmarsh explains, and so it has not been possible to calculate the net present value of fuel savings over a five-year docking cycle. We understand that a full blast and a new coating costs more up-front, but we can now demonstrate that in most cases, it is money well spent. The extra investment invariably pays back by way of fuel savings well within the five-year docking cycle, and sometimes in a matter of months. Emissions are reduced accordingly, he adds.
Intertrac Vision continues to help the industry keep pace with changing regulation. One such example is ISO 19030, the new standard for measuring hull and propeller performance. The requirements for this new standard have been incorporated into AkzoNobel’s recommendations for hull performance monitoring, which means hull coating performance predictions from Intertrac Vision can be verified and validated against actual performance using a monitoring process that is ISO 19030 compliant.
