Vessel type : Bulk carrier
Scope of assessment : Counter verification of the claims from various paint suppliers and suggesting the best grade and vendor.
Result : A suitable vendor was suggested to the client for their paint requirement. Client was also notified about the issue in the data quality of their noon report. Recommendations were provided for them to improve the data quality.
A leading ship management company recently consulted us for an advise on choosing the right marine paint for their vessel which is about to dry dock in 2020. Like any other ship owners in maritime industry they were also confused by the promises offered by various paint suppliers regarding the potential fuel savings.
They were confused on choosing different grades (Low friction or Normal) and suppliers as the cost v/s benefit scenario was not clear for them. They were not confident with reliability and accuracy of the results as it was based on the noon data reports. Theoretical comparison is easy but when it comes to practical scenario it is difficult to validate the results.
In the view of above, we suggested them to categories the data of different paints used in past. Actual gain was not available with them. So we had to depend on the theoretical data. We decided to conduct a ISO 19030 Analysis with the data available.
ISO 19030 – Speed loss analysis
Even though ISO speed loss analysis is preferred for ADA data, it can also used for noon data but with correct exemptions followed. The vessel didn’t had monitoring devices and hence ISO alternative methods and data filters has to be implemented carefully. After mass filtering of data we got result with maximum accuracy. Fuel savings from various paints were provided to client. They used these results to verify the vendor promise and chose a right vendor for their vessel.
With this study they also understood the issues they are facing with the data quality in their noon reports and have started to take corrective measures with our consultancy.
Ship owners are always facing difficulty in counter verifying the results submitted by paint suppliers. Even though paint suppliers use ISO methods it is an industrial practice followed by the paint suppliers to use the cubic relation between power and velocity. It is theoretically correct method, but on reality it varies. So we recommend and follows the usage of actual scenario in our ISO analysis which will give quantifiable results
