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,

Schepen gebruiken veel energie. Vaak kan 50% van de operationele kosten van een schip worden toegerekend aan brandstofkosten. Naast hoge kosten, leidt brandstofgebruik ook tot vervuiling van de lucht (roet, fijnstof, stikstof- en zwaveloxides) en draagt het bij aan het broeikaseffect (koolstofdioxide).

Het gaat bij de scheepvaart snel om grote getallen. Een normaal kustvaartschip verbruikt per dag rond de 8 tot 10.000 liter gasolie. Bij grote containerschepen, met ruim 19.000 containers, loopt het verbruik op tot 200.000 liter per dag bij 22 knopen.
