The tonnage capacity of the Suez Canal has almost doubled since its reconstruction. risk analysis oil and products transportation is carried out in paper, considering this factor from Persian Gulf to America, order reveal economic efficiency existing recommended routes. According research outcomes calculations, it proved that most expensive path route through Canal. It can be profitable on a sh...

This paper presents a new dynamic environmental risk model, with intended use within a new, dynamical approach for risk based ship traffic prioritisation. The philosophy behind this newly developed approach is that shipping risk can be reduced by directing efforts towards ships and areas that have been identified as high priority (high risk), prior to a potential accident. The risk model propos...

This paper proposes a Bayesian belief network (BBN) model for the estimation of accidental oil outflow in a ship-ship collision where a product tanker is struck. The intended application area for this model is maritime traffic risk assessment, i.e. in a setting in which the uncertainty regarding the specific vessel characteristics is high. The BBN combines a model for linking relevant variables...

With the rapid development of global trade and maritime transportation, a comprehensive emission inventory is necessary to control air pollution from ships as well comply with international environmental standards. The purpose this study calculate volume emissions in Yeosu Gwangyang ports Korea based on bottom-up approach supported by data automatic identification system (AIS) Korean port manag...

The conventional method towards deriving schedule for a fleet of ships to minimize cost alone has the short-coming of not addressing the problem of operation revenue losses associated with delays during maintenance at ships dockyards. In this paper, a preventive maintenance schedule for a fleet of ships that incorporates op-portunity cost is presented. The idea is to assign a penalty cost to al...

The ability of tug escort vessels to save oil-laden tankers that become disabled in Prince William Sound, Alaska, is tested using a simulation of the drift path of the tankers. Tug escort schemes are intended to save tankers that have lost steering or propulsion by attaching a line and either holding the tanker from running aground until a repair can be made or towing the tanker to port. The ab...

The coupling motion of heave, pitch and roll of intact ship and damaged ship in waves, and the flow of flood water in damaged tank have been simulated based on viscous theory. The calculation model is a 29000 t tanker model moving at a constant speed with damaged tank in midship area. Three cosine waves including head waves, beam waves and oblique waves are simulated by boundary input method re...

The number of installed offshore wind turbines is continuously growing worldwide in recent years. Offshore farms are generally located near the coast close to traffic lanes and exposed risk collisions from visiting passing ships. Potential consequences may vary local structural damage detachment turbine nacelles rotors, even tower collapse capsizing platform, causing significant economic loss f...

The enlargement of ships has increased the relative hull deformation owing to draft changes. Moreover, design changes such as an propeller diameter and pitch have occurred compensate for reduction in engine revolution consequent ship speed. In terms propulsion shaft alignment, load stern tube support bearing increases, uneven distribution occurs between bearings, leading accidents. To prevent a...
