PREDICTIVE MAINTENANCE FOR MARINE ENGINES

Preventive Maintenance for Marine Engines

Introduction

Preventive maintenance is crucial for ensuring the efficiency and reliability of marine engines, minimizing downtime, and reducing operational costs. This project explores a predictive maintenance approach using a simulated dataset that mimics real-world marine engine performance data. The goal is to classify engine conditions into Critical, Requires Maintenance, or Normal, based on key engine parameters.

Overview

This project focuses on:

• Simulating a realistic dataset for marine engine performance monitoring.

• Applying feature engineering and preprocessing techniques to prepare the data.

• Training machine learning models to classify engine conditions.

• Evaluating model performance and optimizing hyperparameters for better accuracy.

By leveraging machine learning and data preprocessing, this project showcases how predictive maintenance can be applied in the maritime industry.

Tools Used

• Python: Data simulation, preprocessing, and model training.

• Scikit-Learn, XGBoost: Feature selection, classification models, and evaluation.

• Matplotlib & Seaborn: Exploratory data analysis and visualization.

Skills Demonstrated
