Abstract

The 2007–2008 financial crisis, together with rises in fuel prices and stringent pollution regulation, led to the need to update the methods concerning ship propulsion system design. In this article, a set of artificial neural networks was used to update the design equations to estimate the engine power and fuel consumption of modern tankers, bulk carriers, and container ships. Deadweight or TEU capacity and ship speed were used as the inputs for the ANNs. This study shows that even a linear ANN with two neurons in the input and output layers, with purelin activation functions, offers an accurate estimation of ship propulsion parameters. The proposed linear ANNs have simple mathematical structures and are straightforward to apply. The ANNs presented in the article were developed based on the data of the most recent ships built from 2015 to present, and could have a practical application at the preliminary design stage, in transportation or air pollution studies for modern commercial cargo ships. The presented equations mirror trends found in the literature and offer much greater accuracy for the features of new-built ships. The article shows how to estimate CO2 emissions for a bulk carrier, tanker, and container carrier utilizing the proposed ANNs.

Summary

Introduction

Csaba Csiszár and Jereb BorutDue to its massive trade volume and low ship transportation cost, maritime transport has become the bedrock of global goods transportation around the world. With regard to jurisdictional claims in published maps and institutional affiliations. For this purpose, various mathematical relationships are examined between parameters encompassing: Licensee MDPI, Basel, Switzerland. The transport efficiency of the ship, such as deadweight and vessel speed; The energy efficiency of the ship, affected by the total power and fuel consumption of the vessel. A total engine power and fuel consumption estimation of vessels is most often performed at the general transport study stage of the process, with the goal of selecting the mode of transport [1,2]. Żelazny [16] proposed regression equations to estimate propulsion power for container ships, tankers, and bulk carriers
