A Model for Multidisciplinary Optimization for Containerships
This thesis describes a multidisciplinary design optimization approach to containership design. The method employs widely accepted regression equations for computing resistance, weights, building costs and operating costs. The current regulations governing freeboard and the Coast Guard wind heel …

Green water and loading on high speed containerships
… problem and its loading effects on high speed containerships was investigated with the purpose of developing a modelling framework that can practically guide naval architects to a better understanding of this problem and improvements in design. The research began by reviewing extensive …

Robust Yaw/roll Control of High-Speed Containerships
… proposes a controller design for high-speed containerships with aggravated yaw/roll characteristics. With the trend of higher superstructures, low density cargo, and the deck loading of containerships, major problems have arisen in regard to roll motion stabilization. To minimize the yaw/roll …

Engineering and economic implications of ice-classed containerships
… several different ice-classes over conventional containerships. To increase the ice-class slightly, the data is within margins of error and thus, there are no increases (especially with high speed LNG and container vessels). However, to increase the ice-class to the highest class analyzed, the …

Formulation of a Multi-Disciplinary Design Optimization of Containerships
To develop a computer tool that will give the best ship design using an optimization technique is one of the objects of the FIRST project. Choosing a containership design as a test case, the Design Optimization Tools (DOT) package is used as the optimization tool. The problem is tackled from the …

Addition of Features to an Existing MDO Model for Containerships
Traditionally, the "Design Spiral" is used for the design of ships. The design spiral endorses the concept that the design process is sequential and iterative. Though this procedure was very effective over the years, the current trend of engineering demands that more stress be put on the …

Algorithmic Modifications to a Multidisciplinary Design Optimization Model of Containerships
When designing a ship, a designer often begins with "an idea" of what the ship might look like and what specifications the ship should meet. The multidisciplinary design optimization model is a tool that combines an analysis and an optimization process and uses a measure of merit to obtain what it …

Designing Liner Shipping Feeder Service Networks in the New Era of Mega Containerships
Spätestens seit der Einführung von Mega-Containerschiffen planen Reedereien ihre Netzwerke für die Container-Linienschifffahrt nach dem 'Hub-and-Spoke'-Prinzip, um ihre Verbindungen zu regionalen Märkten zu stärken und die operativen Kosten für Kurzstrecken mit niedrigem Frachtvolumen zu …

A Design Methodology for Adaptive Open-Seas Course-Keeping Control of Containerships (Adaptive, Steering, Ship)
During the seventies, the greatly increased price of fuel oil and substantial over-capacity in available tonnage of the world's merchant shipping have combined to cause a major problem for the maritime industry. This has stimulated an increasing interest in research on autopilots for ships. Much of …

A system for the detection of concealed nuclear weapons and fissile material aboard cargo cotainerships
… weapons and fissile material aboard cargo containerships is proposed. The ship-based approach removes the constraints of current thinking by addressing the threat of containerized nuclear terror in a novel way. Critical tactical misjudgments exist in currently deployed detection systems, …

Economic feasibility of shipping containers through the Arctic
… information pertaining to Arctic conditions, containerships and icebreakers, and container ports was collected and used to build a model that estimates the expense and time of port-to-port voyages through the Arctic. Different combinations of vessels, routes, and speeds through the Arctic were …

Estudo das características estocásticas do roll paramétrico
… The results obtained have shown that for containerships the stochastic roll process could be consider as a stationary process. Finally, the extreme roll responses have been used for fitting the Generalized Extreme Value Distribution (GEVD) and the Generalized Pareto Distribution (GPD). …

Systems-based analysis of a ship borne approach for the detection of fissile material concealed in cargo containers
… and shipped in limited numbers aboard commercial containerships. Outfitted with communication hardware, these dedicated containerized units could provide crucial advance detection and notification of an inbound nuclear threat while the danger is still safely removed from U.S. shores. Attributes of …

MEGAPORT : architecture in infrastructural environments
… is a transshipment port solely for ultra large containerships. It affords an economy for such transoceanic ships to remain in sea, and for local ports to be served through feeder ships. The Megaport is self-sufficient, autonomous and off-shore. In this colony of globalization, an infrastructural …

The impact of automation on the efficiency and cost effectiveness of the quayside and container yard cranes and the selection decision for the yard operating systems
… the total turnaroundtime and hence the cost of containerships' waiting-times. It argues, however, that there should be a balance between the cost of containerships' waiting-times and the cost of automated berths' unproductive-times (idle-times). This study uses the elements of queuing theories …

Analysis of marine container terminal gate congestion, truck waiting cost, and system optimization
… to grow and the introduction of 12,000 TEUs plus containerships into major trade routes, the port industry is under pressure to deal with the ever increasing freight volume. Gate congestion at marine container terminal is considered a major issue facing truckers who come to the terminal for …

Strategic Risk and Reliability Assessment in the Container Liner Shipping Industry Under High Uncertainties
… capability (ORC) of LSOs, and 3) punctuality of containerships. To achieve the aim, firstly, this research employed a combination of different decision-making methods (i.e. Analytic Hierarchy Process (AHP), Fuzzy Set Theory (FST) and Evidential Reasoning (ER)) for the assessment of the BEBR. The …

Inter-Port Competition and Inland Container Transport: A multiple Criteria Decision-Making Approach to Achieve Intermodal Transport System Development Stratergies in Taiwan.
… by container carriers. In the 1980's, large containerships only berthed at Kaohsiung port due to the limit of container terminal operation capacities of Keelung port and the carrier's regional hub port decision in the country region. The container traffic of the south-north motorways made …
