Relationship of grain boundary structure and mechanical properties of Inconel 690
(Massachusetts Institute of Technology, 2009)
Stress corrosion cracking (SCC), failure due to environmentally assisted crack nucleation and propagation, is an important metallurgical problem with impact on current and future designs of ship structural components and ...
Impacts of reducing shipboard NOx̳ and SOx̳ emissions on vessel performance
(Massachusetts Institute of Technology, 2010)
The international maritime community has been experiencing tremendous pressures from environmental organizations to reduce the emissions footprint of their vessels. In the last decade, air emissions, including nitrogen ...
Concept design of a long range AUV propulsion system with an onboard electrical generator
(Massachusetts Institute of Technology, 2012)
Automated Underwater Vehicle (AUV) Technology has come a long way in the past decade. Due to advances in batteries and telecommunications, unmanned underwater vehicles no longer require a tether to a mother ship for power, ...
Cost reduction of polar class vessels : structural optimization that includes production factors
(Massachusetts Institute of Technology, 2013)
The design of ship structures was normally optimized to reduce construction material and maintain adequate strength while adhering to a given classification society's rules. In the case of Polar Class vessels, where weight ...
An enhanced propeller design program based on propeller vortex lattice lifting line theory
(Massachusetts Institute of Technology, 2007)
A suite of propeller numerical design tools was developed in MATLAB®, a high-level technical computing language. The tools were based on the FORTRAN programs developed by Professor Justin Kerwin at MIT in 2001 and include ...
Analysis and experiments for contra-rotating propeller
(Massachusetts Institute of Technology, 2011)
Contra-rotating propellers have renewed interest from the naval architecture community, because of the recent development of electric propulsion drives and podded propulsors. Contrarotating propulsion systems have the ...
Improving shipboard maintenance practices using non-intrusive load monitoring
(Massachusetts Institute of Technology, 2007)
(cont.) New casualty parameters were recorded and analyzed in an attempt to verify and expand on diagnostic software currently being developed for the vacuum aided sewage collection system. The analysis of the ships service ...
Engineering and economic implications of ice-classed containerships
(Massachusetts Institute of Technology, 2009)
The Arctic is becoming increasingly attractive for shipping. With the potential savings in transit time and the untapped natural resources, both the shipping and offshore industries are pouring capital into research and ...
Prediction of performance and maneuvering dynamics for marine vehicles applied to DDG-1000
(Massachusetts Institute of Technology, 2010)
Being able to accurately model the performance of ships is an integral part of the ship design process. A considerable amount of money is invested into predicting how a ship will maneuver in a given sea state. Furthermore, ...
Comparison of approaches for determining the failure of stiffened cylindrical shells
(Massachusetts Institute of Technology, 2002)
