Theses and Dissertations
Sensitivity analysis of transient and steady state characteristics of surface ship progressive flooding
(Monterey, California. Naval Postgraduate School, 1999-09)
The Navy's primary analysis of damage control and stability to date has been under static conditions. Dynamic effects, such as progressive flooding, and the dynamic damage control procedures, such as hole patching and ...
A methodology for design of passive isolation for ship/barge connection
(Monterey, California. Naval Postgraduate School, 1999-09-01)
Current ramp designs used in RORO operations have been determined to be structurally inadequate in Sea-State 3. The main reason for this is that when the ramp is loaded with two vehicles, the relative motions between the ...
Improved computer modeling of ship progressive flooding as a design tool
(Monterey, California. Naval Postgraduate School, 1998-09-01)
When a ship suffers underwater damage, there is a rapid influx of water, followed by a period of slower progressive flooding. This results in flooding of compartments whose hull boundaries, but not interior bulkheads, are ...
Bias effects on motion stability of submersible vehicles
(Monterey, California. Naval Postgraduate School, 1998-09)
This thesis analyzes the nonlinear characteristics of motion stability of a submersible vehicle in combined sway, yaw, and roll motions. Previous results, at zero pitch angles, indicate that limit cycles are generated as ...
Multiple input sliding mode control for autonomous diving and steering of underwater vehicles
(Monterey, California: Naval Postgraduate School, 1990-12)
Design and analysis of multiple input autopilots using sliding modes in order to achieve accurate horizontal and vertical plane control of an autonomous underwater vehicle over a wide variation of speeds is presented. The ...
Dynamic stability of positively buoyant submersibles : vertical plane solutions.
(Monterey, California. Naval Postgraduate School, 1991-12)
This thesis analyzes the dynamic stability of positively buoyant submersibles. Six
degree -of- freedom equations of motion are used to compute steady state behavior with
motion restricted to the vertical plane. Steady ...
Characterization of sway forces induced by close proximity ship towing
(Monterey California. Naval Postgraduate School, 2002-03)
The scope of this thesis is to characterize the connection forces in the horizontal plane of surface ships in close proximity towing in waves. Strip theory calculations are used in order to predict the hydrodynamic ...
Frequency response analysis of T-ACS experimental data
(Monterey, California. Naval Postgraduate School, 2000-09)
Trial runs of a 1:24 scale model crane ship were conducted in the David Taylor Model Basin. The model's response to regular waves under various ship configurations, crane configurations, sea states and ship headings relative ...
Reference path generation and tracking of marine vehicles
(Monterey, California. Naval Postgraduate School, 1992-09)
This thesis analyzes the problem of accurate path following for marine vehicles. The reference path is generated automatically through the use of a critically damped second order model. An appropriate shift in the time ...
Development of a SIMSMART based, progressive flooding design tool
(Monterey, California. Naval Postgraduate School, 1999-03-01)
While the Navy addresses the effects of progressive flooding in its design requirements, its limits for damaged stability are the results of World War II damage analysis and are evaluated under static conditions, without ...
