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 ...
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 ...
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, ...
Modular machinery arrangement and its impact in early-stage naval electric ship design
(Massachusetts Institute of Technology, 2012)
Electrical power demands for naval surface combatants are projected to rise with the development of increasingly complex and power intensive combat systems. This trend also coincides with the need of achieving maximum fuel ...
