Ocean vector winds measured by the SeaWinds scatterometer onboard the QuikSCAT satellite can be validated with in situ data. Ideally the comparison in situ data would be collocated in both time and space to the satellite overpass; however, this is rarely the case because of the time sampling interval of the in situ data and the sparseness of data. To compensate for the lack of ideal collocations, in situ data that are within a certain time and space range of the satellite overpass are used for c...

The Modular Multilevel Converter (MMC) is a potential candidate for power conversion in a Medium Voltage DC System (MVDC) based electric ship. One of the major advantages of utilizing MMC in an MVDC environment is the capability of limiting DC side fault current and fast re-start process because re-energizing of the MMC cells is not necessary. The MMC cells have various configurations e.g. half-bridge, full-bridge. The full-bridge MMC is more suitable for the ...

The power management strategy in a MVDC based power system of an all electric ship (AES) with Hybrid Energy Storage System (HESS) can greatly affect the energy efficiency of the system. In order to maintain the bus voltage of a medium voltage DC (MVDC) shipboard power system within the allowable margin with the operation of different types of loads, the energy storage has become indispensable part of the AES. With the aim of supporting the MVDC shipboard power system, an energy storage managemen...

Britain and Japan, fellow island nations, share many geographical similarities, and accordingly both societies have long taken advantage of water transport domestically. In modern times the two nations’ governments have diverged in terms of philosophies toward economy and industrialization. Britain is known as today’s consummate private-industry advocate within western Europe, while Japan is noted for the strong level of government “guidance” in its post-WWII economy. Using the abovementioned...

The purpose of this dissertation is to investigate the feasibility of using neural networks in conjunction with the Fourier Modified Direct Mellin Transform (FMDMT) for the recognition of ship targets. The FMDMT is a modification of the Direct Mellin Transform for digital implementations, and is applied to the magnitudes of the Discrete Fourier Transforms (DFT) of range profiles of ships. Necessity for the use of the FMDMT is corroborated by the fact that features can be extracted from the range...

These simple shapes, namely a v-bottom (triangle) hull, a at-bottom (square) hull and a round-bottom (semi-circle) hull, are investigated in uncoupled heave, sway and roll. The problem is described in two dimensions. A combination of numerical methods and models, found in literat...

Despite an extensive system of Port state controls (PSC) on ships, inspection loopholes in European control functions have been reported. Furthermore, risk factors associated with fatigue, stress and a poorly developed safety culture on board ships have been identified in earlier research. These combined risk factors may pose a serious threat to maritime safety. With this as a point of departure, this thesis aims to investigate the perceived work situation for Swedish inspectors from an inspecto...

The trend in offshore oil and gas industry has been that new oil and gas fields are more remote in terms of water depth and in distance from existing infrastructure. The high price for oil and gas drives the industry to develop fields in harsh environment and record breaking water depths. Fixed offshore structures are not feasible for ultra deep water depths and may also be less profitable or unprofitable for moderate depths. This is due to the high cost of laying export pipelines in remote area...

A practical way to estimate the ship response in early design stage is investigated in this thesis. Focus has been put on the ship vertical bending moment and shear force in operation area. ISSC spectrum is used to indicate the sea state. Napa strip method is employed to derive the transfer function. The ship response is thus generated in frequency domain. The vertical bending moment and shear force along the ship are then calculated according to the critical wave case indicated from the respons...

This report aims to explore a possible transparent alternative to the black box approach of machine learning in identifying a ship’s type from simple movement data, consisting of a set of coordinates with timestamps. This is achieved by an application that converts the set of coordinates to vectors and assigns them various traits, such as turn radius, speed and distance traveled, and then identifying the correlation between collections of different values of these traits, called granules, and di...

Multiple myeloma (MM) is a B-lymphocyte neoplasia that remains incurable due in part to intrinsic and acquired drug resistance, despite the numerous conventional therapies available. The growth, survival and anti-apoptosis signals resulting from adhesion and cytokine-mediated interactions between the malignant clones and the bone marrow microenvironment are transduced chiefly through the elevated phosphoinositide 3-kinase (PI3K) signaling pathway, which has been demonstrated essential for diseas...

In the mid-nineteenth century, the construction of wooden sailing vessels became the single most important employer in Quebec City. Thousands of people worked as shipwrights in the shipbuilding industry, but ship carpenters were the backbone of the trade. These workers displayed an extraordinary capacity for mobilization, being responsible for some of Canada's earliest labour organizations, starting in 1840 with the Societe amicale et bienveillante des charpentiers de vaisseaux de Quebec.

<p> Since its completion in 1910, the Chicago Sanitary and Ship Canal (CSSC) has become a pathway for invasive species (and potentially Asian carp) to reach the Great Lakes. Currently, an electric barrier is used to prevent Asian carp migration through the canal, but the need for a secondary method is necessary, especially when the electric barrier undergoes maintenance. The underwater Asian carp &ldquo;cannon&rdquo; (water gun) provides such a method. Analysis of the ground movement produced...
