Movable bed, scale model experiments were conducted at three length scales, 1/8.5, 1/10 and 1/11, in a 90 ft-long wave tank to study scale effect and equilibrium profile characteristics under sinusoidal, accreting wave action. Geometric similarity, deep water wave steepness, wav…
A hyperboloidal low order source-doublet steady/unsteady time domain panel method code PROPELLA was modified and used to evaluate effects of hub taper angle and pod-strut geometry on the open water propulsive performance of a fixed pitch screw propeller used in podded propulsion…
This thesis studies the impact, on a painted surface, of the presence of some natural oils (olive, mustard, and fish oil) and proteinaceous substances derived from ground insects and eggs. The performance of both water-based and oil-based coatings has been tested in a series of …
Two mechanical systems are investigated during the course of the present study. In the first system a simplified offshore structure subjected to wave loading is delineated, through which a unified second-order stochastic averaging approach suitable for practical nonlinear ocean …
This study investigates and determines certain aspects of section 5 of Decree No. 10 of 1987 on the National Shipping Policy. It deals with the relative cost of construction of comparable vessels in Nigeria and in foreign countries (i.e. USA, U.K. Japan, and S. Korea). The Niger…
The primary objectives of this study were to better understand the remote sensing mechanisms of ocean internal waves, and to apply space shuttle data to studies of upper ocean processes. Space shuttle photographs and Spaceborne Imaging Radar-C images of the Arabian Sea area were…
The survey was conducted along 2,475 kilometers of tract in the South China Sea offshore East Peninsular Malaysia to evaluate the presence of placer gold, tin and heavy minerals, as well as sand resources. Geophysical methods were employed, consisting of high resolution seismic …
This record of study presents a professional internship experience of the author in the Development Division of Total Indonesie. This internship and report are in partial fulfillment of the requirements for the Doctor of Engineering degree. The objective of this internship was t…
An Integrated Coastal Engineering model (ICEM) has been developed, which models the waves, the coastal circulation and the rates of bed level changes simultaneously. The wave model simulates the combined effect of refraction, diffraction, shoaling, reflection and breaking and th…
KYRA M. BRYANT. Hurricane Storm Surge from Irma and Maria in Puerto Rico and the Virgin Islands: Dissecting Wind, Pressure, Forward Speed, and the Saffir-Simpson Hurricane Wind Scale under the direction of DR. MUHAMMAD AKBAR. Most American hurricane studies concentrate on the Gu…
The use of empirically developed procedures in fatigue life predictions is current practice for notched members under the joint action of mechanical loads and a corrosive environment. A simple model has been investigated where the total fatigue life of a notched member is consid…
The steady and unsteady ship propeller problem is solved in terms of linearized lifting surface theory both generally and particularly for the case of propeller blades of low aspect ratio. A principal result of this study is that consistent formulas are found for the induced vel…
The Seaformatics project is a five year AIF project that intends to develop to a proof-of-concept seafloor array of wireless marine sensors for use in monitoring seabed processes, including applications such as geological imaging and earthquake detection. Individual low cost sen…
The focus of the research is the evaluation of dynamic and static pressures acting on floating bodies. Specifically, these pressures result from large motions of a multi-hull ship in 6 dof. The components of the dynamic pressure are radiation, diffraction, and the Froude-Kriloff…
Corpus Christi Bay (TX, USA) is a shallow wind-driven bay which is designated as a National Estuary due to its impact on the economy. But this bay experiences periodic hypoxia (dissolved oxygen <2 mg/l) which threatens aerobic aquatic organisms. Development of the Coastal Margin…
The current research investigates the performance of podded propulsors with varied geometry at different azimuthing conditions for pusher and puller configurations in open water. In order to determine the prominent geometric parameters and to establish their effects on the hydro…
Durability of the composite materials in marine environments has been investigated experimentally and with analytical and numerical methods. The main focus of this study is on the integrity of the fiber/matrix interface under seawater exposure. A single-fiber compression test sp…
