Cost prediction via quantitative analysis of complexity in U.S. Navy shipbuilding
(Massachusetts Institute of Technology, 2014)
As the sophistication and technology of ships increases, U.S. Navy shipbuilding must be an effective and cost-efficient acquirer of technology-dense one-of-a-kind ships all while meeting significant cost and schedule ...
Creating a shipboard power simulation tool using electrical load behavior modeling
(Massachusetts Institute of Technology, 2020)
Trends in power system simulation that demand computationally-intensive, physics-based models may impede the acquisition of useful results for applications like condition-based maintenance [1], electrical plant load analysis ...
Quantification of extreme event statistics in ship design
(Massachusetts Institute of Technology, 2019)
Increased operational demands on Navy vessels extend time at sea and service life, making the accurate prediction of catastrophic failures increasingly challenging. The high value of these capital assets puts great pressure ...
Hydrodynamic analysis of the offshore floating nuclear power plant
(Massachusetts Institute of Technology, 2015)
Hydrodynamic analysis of two models of the Offshore Floating Nuclear Plant [91 was conducted. The OFNP-300 and the OFNP-1100 were both exposed to computer simulated sea states in the computer program OrcaFlex: first to ...
Beamforming performance enhancement by adaptive hyperbola array shape estimation
(Massachusetts Institute of Technology, 2020)
Analysis of U.S. Navy Ice Exercise 2016 (ICEX16) data, through a collaboration with MIT Lincoln Laboratory, demonstrated that towed array curvature commonly exhibited heading differences up to 100° and never maintained ...
Using the principles of set-based design to realize ship design process improvement
(Massachusetts Institute of Technology, 2016)
Set-based design (SBD) is a relatively new complex product development method. Its use has been well researched in the automotive and aerospace industries and, although it requires an upfront investment in resources, it ...
Resilient acquisition : unlocking high-velocity learning with model-based engineering to deliver capability to the fleet faster
(Massachusetts Institute of Technology, 2019)
As the nation's security needs call for a growing naval fleet, the public-private industrial base for construction and weapon system acquisition will be stressed to perform at a high level of operational excellence. While ...
Naval applications of enhanced temperature, vibration and power monitoring
(Massachusetts Institute of Technology, 2015)
Navy ships require reliable information regarding their power and mechanical systems in order to perform their mission effectively. While today's shipboard systems are quite sophisticated, there are areas for improvement ...
Design and analysis of US Navy shipbuilding contract architecture
(Massachusetts Institute of Technology, 2015)
Contracting for US Navy ship procurement is complex due several factors such as budgetary and political concerns, sole or near sole source environments, and long lead-time construction. In the current climate of shrinking ...
Use of an asymmetric propeller for unmanned underwater vehicles
(Massachusetts Institute of Technology, 2019)
This thesis describes the development and execution of a test program to determine the suitability of an asymmetric propeller for unmanned underwater vehicles (UUV). The idea to utilize a single blade propeller had been ...
