Comparative Performance Evaluation of B-Series and Kappel Propeller Design Methods for an Oil Tanker Vessel

Abstract

The maritime sector's reliance on efficient and dependable propulsion systems is crucial for the secure and cost-effective movement of goods and passengers worldwide. Ship propellers, as the primary mechanism for converting engine power into thrust, play a pivotal role in optimizing vessel performance. This study presents a comparative analysis of two prominent ship propeller design methodologies: the B-Series and Kappel methods. The study focuses on an oil tanker powered by a 13,000 KW engine, sailing at a speed of 15.2 knots. By calculating the required propeller diameter and evaluating the performance in terms of thrust power and efficiency, the research aims to elucidate the strengths and limitations of each design approach. Results indicate that the Kappel method significantly outperforms the B-Series method in both thrust power and efficiency, achieving a thrust of 1678.8 KN and an efficiency of 62.3%, compared to 1047.7 KN and 59% for the B-Series propeller. However, the Kappel method's higher computational complexity and cost are notable considerations. These findings provide valuable insights for ship designers, naval architects, and marine engineers, highlighting the importance of selecting the appropriate design methodology based on specific vessel requirements and operational conditions.
