The presence and abundance of non-indigenous, and/or harmful or toxic dinoflagellate species in ballast sediments is examined for 65 cargo ships visiting ports on the East coast of Canada, as part of the Canadian Aquatic Invasive Species Network (CAISN). Ships visiting several ports in the provinces of Quebec, New Brunswick and Nova Scotia were sampled during three summers (2007, 2008, 2009). T...
A new type of interactive attraction in mixed reality environment, BLADESHIPS, has been designed and developed. The BLADESHIPS is a game in which players compete with each other by controlling virtually expressed belt-shaped flying object, “ships”, with their hands in real environment. They control their own ships by avoiding other ships and real/virtual obstacles. They try to drive enemy ships...
Maritime intermodal container terminals (CTs) are complex hub systems in which multiple transport modes receive and distribute freight to various destinations. They can be considered as interchange places in a transport system network where seaways, railways, and motorways intersect. Freight is usually organized, transported, stacked, handled and delivered in standard units of a typical contain...
The paper addresses various design aspects of survivability for surface naval and merchant ships through a common rational probabilistic methodology. It is based on earlier work of Kurt Wendel on a probabilistic approach to the damage stability of surface ships. This method was adopted by SOLAS 1974 through Res. A.265 (VIII) as an alternative to the deterministic SOLAS criteria for passenger sh...
The choice of roll stabilization system is critical for many types of ships. For warships where operational activities are fast and the concept of time is very effective, determining the most appropriate of these systems is of particular importance. Some operations, such as the landing of the helicopter on board, are critical for naval ships. Unwanted rolling motion makes this difficult. In add...
BACKGROUND Despite international notification requirements, the magnitude of disease transmission on board ships remains undetermined. This case series aims to exemplify that varicella aboard ships is a topic of interest for maritime medicine and of public health significance. MATERIAL AND METHODS Systematic presentation of cases of chickenpox reported to the Hamburg Port Health Authority bet...
Alarm indicators are a very simple and important user interface for many control tasks, and are known to be problematic. Alarms on ships have increased in number and importance. Recent incidents such as Savannah Express, Aquitaine and others have identified a number of important issues in the way that alarm systems support safe and effective work. The state of alarm systems onboard is inconsist...
According to IMO forecasts, CO2 emissions from world shipping could double by the year 2050. Although shipping is in most cases the most efficient mode of transport per unit of transport supply, it is still heavily reliant on heavy fuel oil to power its propulsion. The IMO has introduced regulations to bring about reductions in the emissions of ships, including an Energy Efficiency Design Index...
Maritime transportation is a major source of climate change and air pollution. Shipping emissions cause severe impacts on health and environment. These effects of emissions are emerged especially in territorial waters, inland seas, canals, straits, bays, and port regions. In this paper, exhaust gas emissions from ships in Izmir Port, which is one of the main ports in Turkey, are calculated by t...
This paper proposes a method for estimating emissions of carbon dioxide (CO2) and particulate matter (PM) from ships using Automatic Identification System (AIS) data. The method can be summarized in three steps : 1) capture of AIS data, 2) estimation of ships resistance, propulsion power, engine power and fuel consumption, 3) estimation of CO2 and PM emissions based on fuel consumption. The met...
