Material Selection for Engine Casing of an Oil Tanker: MECH3400 Report

This report undertakes a comprehensive material selection process for an oil tanker engine casing, a critical component responsible for enclosing and protecting internal engine parts. The analysis begins with defining the engine casing's function and identifying relevant loading conditions, followed by establishing key material properties and constraints, including density, strength, hardness, fatigue resistance, and thermal properties. The study employs screening methods using Granta CES software to narrow down material choices, considering factors like composition, physical and mechanical properties, durability, and shape. Material indices are derived to rank the shortlisted materials based on price and performance. The report also investigates competing constraints and manufacturing processes, including centrifugal casting, filament welding, polymer casting, and reaction injection molding. Ultimately, the report provides recommendations for the most suitable material, considering all aspects of the engine casing's requirements.
