Most charterers monitor performance by using noon report data that is collected manually at sea and reported back to shore once per day. This noon data is the basis for performance claims. We believe that using noon data is not sufficient. Now, high-quality vessel performance data can boost your success rate in the settlement of such claims.
In a recent project, We4Sea was approached by a charterer that suspected severe underperformance of one of their chartered vessels, during a laden leg from Brazil to China. However, due to bad weather during the voyage, no conventional calculation could be carried out, as this needs sufficient good weather days.
The vessel experienced time loss which was blamed on bad weather by the owners. During a stop in Singapore, an intermediate hull cleaning was carried out.
The charterer suspected that not only bad weather contributed to the time loss for the first leg, but also the hull fouling. Pictures made before the cleaning confirmed this.
We4Sea investigated and calculated the magnitude of speed loss due to bad weather, and hull fouling by comparing the data reported by the ship to a digital modelled version of the ship, the Digital Twin.
The voyage has been ‘re-sailed’ using the Digital Twin in various configurations, yielding both the extra fuel consumption due to hull fouling, as well as the speed the vessel would have been able to sail were she in good condition.
Also, it was found that there was no overconsumption anymore after the hull cleaning, proving the vessel was severely fouled on the first leg.
Based on 11,000 data points (on average 275 per day) for the whole voyage, we were able to make a substantiated overconsumption claim of over 200 MT, and a 1,5 days time loss for the entire voyage, giving the charterer grounds for a total claim of €150,000. A substantial settlement was reached based on this analysis.
The conventional approach, with only 40 data points (being the noon reports) was just not good enough. Smart data did the trick.
