Hull & Propeller Efficiency

Boost the efficiency of your vessel’s hull & propeller.

Icon - Hull & Propeller EfficiencyAnalyse and understand how your vessel’s hull & propeller is influencing fuel consumption and efficiency using key performance indicators. Make actionable real-time decisions to optimise operations.


 

Understanding ISO 19030 – Hull & Propeller Performance

In the ISO 19030 finalised in 2016, methods of measuring changes in hull and propeller performance, and performance indicators for hull and propeller maintenance, repair and retrofit activities were outlined. Hull and propeller performance refers to the relationship between the condition of a ship’s underwater hull and propeller and the power required to move the ship through water at a given speed.

 


 

How does hull & propeller impact fuel consumption?

The International Maritime Organization (IMO) has estimated that poor hull and propeller performance account for about 10% of the world fleet’s fuel consumption. The main reason is due to fouling where marine growth on the ship hull creates roughness and ship hull degradation, thereby causing more drag in the water. With this increased ship resistance, the vessel speed is reduced and more fuel is needed to propel the vessel. Increased fuel consumption translates to higher operating costs and exhaust emissions for ship owners and operators, which may not be economically and environmentally ideal in the long run.

 


 

Optimising operations using Shipulse Hull & Propeller Efficiency

 

Hull & Propeller Efficiency In the ISO 19030-3 voluntary standard, potential approaches were suggested for ship operators to have an indication of overall ship and hull performance, including noon report data collection. However, moving with the times of digital transformation in the maritime industry, a better way for ship owners and operators to proactively monitor their vessels’ hull and propeller is to use an automated measurement system that analyses data in a reliable manner. Compared to traditional noon reporting, continuous monitoring provides more data points for greater accuracy and reduces human error significantly in the measurement process.

 

The cloud-hosted Shipulse Hull & Propeller Efficiency module that is integrated with Shipulse Portal online, used together with supporting onboard sensors and equipment like Torquemet torque meters and Flowmet flowmeters, presents critical hull & propeller data according to ISO 19030 standards. It triggers an alert when performance deviation exceeds the limits set.

It also tracks performance deviation across a series of metrics, including:

  • Dry-docking performance
  • In-service performance
  • Maintenance effect
  • Maintenance trigger

These metrics give operators insights and allow analysis of propeller performance, providing benchmarks for comparison to improve and optimise ship performance. Using such data-driven approach is also helpful for ship owners and operators to know when to optimally time the frequency of hull and propeller cleanings such that it is economically viable and effective for optimal vessel operations.
