Vortex Induced Vibrations of cylinders : experiments in reducing drag force and amplitude of motion
(Massachusetts Institute of Technology, 2007)
Reducing the deleterious effect of Vortex Induced Vibrations (VIV) in marine risers is an important task for ocean engineers; and many competing factors exist in the design of VIV suppression devices. This thesis explores ...
Design considerations for engineering Autonomous Underwater Vehicles
(Massachusetts Institute of Technology, 2007)
Autonomous Underwater Vehicles (AUVs) have been established as a viable tool for Oceanographic Sciences. Being untethered and independent, AUVs fill the gap in Ocean Exploration left by the existing manned submersible and ...
Variable buoyancy system metric
(Massachusetts Institute of Technology, 2009)
Over the past 20 years, underwater vehicle technology has undergone drastic improvements, and vehicles are quickly gaining popularity as a tool for numerous oceanographic tasks. Systems used on the vehicle to alter buoyancy, ...
Verification of a six-degree of freedom simulation model for the REMUS autonomous underwater vehicle
(Massachusetts Institute of Technology, 2001)
mproving the performance of modular, low-cost autonomous underwater vehicles (AUVs) in such applications as long-range oceanographic survey, autonomous docking, and shallow-water mine countermeasures requires improving the ...
Seafloor ripples created by waves from hurricane Ivan on the west Florida shelf
(Massachusetts Institute of Technology, 2006)
Recent studies have shown that the presence of sand ripples on the seabed improves sonar detection of buried mines at sub-critical angles. Sidescan sonar data of ripples off on the west Florida shelf were collected as part ...
Single Transponder Range Only Navigation Geometry (STRONG) applied to REMUS autonomous under water vehicles
(Massachusetts Institute of Technology, 2005)
A detailed study was conducted to prove the concept of an iterative approach to single transponder navigation for REMUS Autonomous Underwater Vehicles (AUVs). Although the concept of navigation with one acoustic beacon is ...
Analysis of 2-axis pencil beam sonar microbathymetric measurements of mine burial at the Martha's Vineyard Coastal Observatory
(Massachusetts Institute of Technology, 2005)
The changing state of warfare has driven the US Navy's area of operations closer to shore into littoral coastal waters. Mine Warfare has been proven as an extremely effective means of battlespace control in these waters. ...
