Containership Load Planning with Crane Operations
… of ports has become an important issue in containership operations. Arrangement of containers both within the container terminal and on the containership play an important role in determining the berthing time. The berthing time of a containership is mainly composed of the unloading and …

Global Optimization of the Nonconvex Containership Design Problem Using the Reformulation-Linearization Technique
The containership design problem involves optimizing a nonconvex objective function over a design space that is restricted by a set of constraints defined in terms of nonconvex functions. An application of standard nonlinear optimization methods to such a problem can at best attain a local optimum …

Application of Multivariable Control Theory to Improve Steering and Propulsion Control of a Containership
… control problems are considered for the SL-7 containership. Extending previous work by Reid in the area of minimum-added-resistance steering control, modern multivariable control methods are applied to the steady-state coursekeeping control problem. Specifically, the full loop-transfer …

Application of hydrogen marine systems in high-speed sea container transport
… hydrogen system of a high-speed foil-assisted containership. This ship is capable of transporting 600 industry standard 20’ containers on long-haul ocean routes, i.e. 5000 nautical miles, at a speed of 64 knots (118.5 km/hr). Such ship performance is not feasible with conventional marine fuels. …

Estudo das características estocásticas do roll paramétrico
… Numerical realizations of the motions of a containership type vessel have been generated for the purpose of studying the stationarity and ergodicity of the roll motion under parametric resonance conditions. The results obtained have shown that for containerships the stochastic roll process …

Formulation of a Multi-Disciplinary Design Optimization of Containerships
… 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 ship owner's point of view. The required freight rate is chosen as the objective function because the …

Network design and fleet allocation model for vessel operation
Containership operators in the U.S. are confronted with a number of problems in the way they make critical fleet allocation decisions to meet the increase of shippers' demands. Instead of the empirical approach, this research describes an optimization method for the fleet allocation problem This …

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 …

Strategic Corporate Social Responsibility in the Container Shipping Industry: A Case Study of the Triple E as part of Maersk's Sustainability Strategy
… a case study of Maersk's SCSR and its biggest containership, the Triple E. With focus on Maersk Line´s innovative Triple E project, this research aims to demonstrate the environmental and overall benefits of the company´s full immersion in SCSR practices. This study further analyses the Triple …

LNG as a transition fuel for shipping in emission control areas
… vessels (tankers, bulk carriers, and a containership) around the world. All analyses throughout this project were performed using actual data obtained from commercial vessels, as mentioned previously. Both on-board and on-shore (cold ironing) power generation methods were examined for …

A Model for Multidisciplinary Optimization for Containerships
… 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 criterion are included. …

Time domain simulation of hydroelastic response of ships in large amplitude waves
… methods are applied to the S-175 containership, for which experimental measurements of motions and loads in large amplitude regular head waves are available. Comparisons made between predictions and measurements (heave and pitch motions, vertical acceleration and vertical bending …
