Title: Air Layer Drag Reduction Applied To Flat-Plate Resistance Testing

Abstract: Throughout the history of naval architecture the idea of reducing frictional resistance has been the focus of extensive theoretical and experimental research. One potential method for reducing drag is the use of air on the underside of a vessel in the form of Bubble-Induced-Skin-Friction Drag-Reduction (BDR) and Air-Layer-Drag-Reduction (ALDR). The latter, ALDR, is the focus of this thesis. This document covers flat-plate experimental research conducted using the Webb Institute Flow Channel during the spring of 2012. The objectives of this project were to demonstrate drag reduction at a variety of conditions, including varying speeds, air injection rates, and deadrise angles. A secondary objective was to map the distribution of air migration on the underside of the surface as a function of these conditions. During experimentation conclusive evidence was gathered to support the validity of the ALDR concept, although scaling has not been addressed. Some recommendations for continued work include exploring this concept in experimentation of air entrapment hull forms or analysis of performance characteristics for full-scale implementation.

Title: Numerical Simulations of Stiffened Panels under Compressive Loads and Structural Analyses of Midship Section

Abstract: In this paper, structural integrity of ship structures is discussed using Finite Element analyses. Buckling behaviors of shell structural components are investigated taking into account geometric and material nonlinearities. Recommendations are made to Naval Architects based on tools developed throughout the research.

Title: North American Emission Control Areas Regulations and the Use of Liquefied Natural Gas Fuels as a Viable Solution

Abstract: The purpose of this paper is to first, to present an overview of the relatively recent North American Emission Control Area (ECA) Regulations imposed by the International Marine Organization (IMO) amendment to the International Convention for the Prevention of Pollution from Ships (MARPOL, Annex VI) in 2010, as well as to show how other organizations, namely the United States Environmental Protection Agency (EPA) have been instrumental in promoting the implementation of these regulations.
