One of the biggest performance killers that all shipping companies face is hull fouling. From the first day the vessel touches the water, fouling starts to build up and increases the hull resistance – resulting in higher fuel consumption.

Even minor biofilms affect the hydrodynamics of a ship’s hull by increasing drag and, therefore, the required propulsive power. Fouling conditions can grow worse if the vessel has long idle periods or low activity such as frequent stays in port, and the rate of growth increases with seawater temperature.

Typically, ship owners clean their vessels at regular intervals, but it would be better when the interval is based on the actual hull condition. But hull condition monitoring is a very complex task due to its many variables, like weather impact, different load conditions, varying service speeds, and draughts, water currents, etc. Both sensor data and noon-data will not show the impact of these effects.

Using a model-based monitoring system combined with noon-reports or sensor-based measurement data offers significant benefits when compared to stand-alone monitoring systems.
As there are virtually no upfront costs and no need for installation and maintenance of sensors, the model-based approach combined with noon-reports reduces investment costs and monitoring costs significantly.

By comparing the fuel consumption before and after a hull cleaning, while taking into account changes in speed, draft, and weather, the business case of hull cleaning can be calculated. Based on actual projects, we see that the Return on Investment can be less than 1 month!

Upgrade your performance analysis today

We believe that real-time, accurate data with full transparency on vessel performance is essential. We have developed new, model-based tools to help in the real-time performance monitoring of vessels.

It’s time for a new approach to performance monitoring of vessels. And the good thing: you can start today!
