Marine propeller efficiency is a measure of how effectively a ship’s propeller converts engine power into thrust to propel the vessel through water. It plays a vital role in determining the vessel’s fuel consumption, operational costs, and overall energy efficiency.
In the broader framework of ship propulsion efficiency, the propeller is a critical component. Even minor inefficiencies—caused by factors such as marine fouling, blade damage, or inadequate maintenance—can significantly impact performance. These inefficiencies lead to increased fuel usage, elevated emissions, and reduced profitability.
Measuring and monitoring propeller efficiency is, therefore, essential for shipowners and operators who aim to optimize propulsion performance, ensure environmental compliance, and make informed, cost-effective maintenance decisions.At Neptunus, we offer TorqueSense, an advanced propeller efficiency measurement system that empowers shipowners with actionable insights. TorqueSense accurately measures not only shaft torque and power in real-time but also the drop in propeller efficiency and Stern tube bearing health, helping operators differentiate between performance issues such as marine fouling and blade damage—two major contributors to propulsion inefficiency.
By delivering reliable data on propeller performance, TorqueSense transforms guesswork into precision, helping operators optimize vessel performance, reduce fuel consumption, and improve decision-making around cleaning and maintenance schedules.
Whether it’s distinguishing between the drag caused by marine growth or identifying early signs of blade deformation or damage, TorqueSense delivers clear, actionable intelligence to improve marine propeller efficiency and overall ship propulsion performance.
