Amsterdam Canals: Topographic Views
2013Co-Authors: Gilchrist ScottAbstract:Large Ferry Boats (cabin cruisers); Amsterdam, capital of the Netherlands, has more than one hundred kilometres of canals, about 90 islands and 1,500 bridges. The three main canals, Herengracht, Prinsengracht, and Keizersgracht, dug in the 17th century during the Dutch Golden Age, form concentric belts around the city, known as the Grachtengordel. This was placed on the UNESCO World Heritage list in 2010. A fourth outer canal belt, the Singelgracht was built for purposes of defense and water management. There are also many interconnecting canals along radii of the belts. In addition, the river Amstel flows through the center of the city. HouseBoats were once a way to deal with the post-WWII Amsterdam housing shortage, however, nowadays they are in high demand; there are approximately 2,400, with 750 of those in the inner canal ring. They are regulated (by number of licensed mooring places) and since 2005, tied into the city water and sewage systems. Some of the houseBoats are converted cargo vessels, others are purpose-built.

Hong Kong: Topographic Views of Victoria Harbour Shoreline
2009Co-Authors: Gilchrist ScottAbstract:Double decked Ferry Boats in Victoria Harbour; Topographic and urban views shot from the south, from the Kowloon pennisula side (Tsim Sha Tsui) of Victoria Harbour, looking north at the Hong Kong island shoreline and the city of Victoria. Victoria City, or statutorily, the City of Victoria, was one of the first urban settlements in Hong Kong after it became a British colony in 1841. It was initially named Queenstown but was soon known as Victoria. It was often said to be the capital of Hong Kong, and almost all government departments still have their head offices located in the area. The city name Victoria has been eclipsed by Central District in popular usage. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 4/22/2011

Análisis de casos más frecuentes de vibraciones en sistemas de propulsión
'Corporacion de Ciencia y Tecnologia para el Desarrollo de la Industria Naval Maritima y Fluvial - COTECMAR', 2013Co-Authors: Domínguez Ruíz, Franklin JhonnyAbstract:This study is a review of cases of propulsion systems in which noise, vibration, or fracture problems have existed. Case studies are presented on passenger vessels, tugBoats, tankers, and Ferry Boats. Each case is addressed based on lateral, torsional, axial vibration analysis, as well as the case analysis of the possible coupling of frequencies or possible defect or deterioration of a component. Based on the cases, a summary is presented of inertial masses of each system analyzed to establish possible problems and benchmark statistical considerations when selecting the components of a propulsion system. Calculations were performed using the ShaftDesigner software from Machine Support, Holland and Torcal software from Tecnavin S. A.El presente estudio constituye una revisión de casos de Sistemas de Propulsión, en los que se han presentado problemas de ruido, vibraciones, fracturas. Los casos de estudio son presentados en naves de pasajeros, remolcadores, tanqueros, lanchas Ferry. El abordaje de cada caso se presenta basado en el análisis de vibraciones, laterales, torsionales, axiales, según sea el caso, análisis del posible acoplamiento de frecuencias o posible defecto o deterioro de algún componente o defecto de construcción. En base a los casos presentados, se presenta un resumen de masas inerciales de cada sistema analizado, para establecer, estadística referencial de problemas y posibles consideraciones al momento de seleccionar los componentes de un Sistema de Propulsión. Los cálculos son realizados usando el software ShaftDesigner de Machine Support, Holanda y Torcal de Tecnavin S. A

Rio de Janeiro: city of contrasts, quality metro
Tramways & Urban Transit, 2005Co-Authors: C J WansbeekAbstract:This article describes the light rail metro system in the city of Rio de Janeiro, Brazil. Standard-gauge tramways were the backbone of Rio's transportation system until the 1960s when bus routes took over: streets are now congested, leading to delays. The railway remains an important means of transport and the underground and above ground metro system has not been expanded since its installation in 1979. Private operation of the metro commenced in 1998 and the trains and infrastructure have been upgraded, increasing use. Interchanges between the two lines are congested at commuter times and it is hoped that an extension line will be funded by the govenment to ease this. There are plans in existence for a six-line metro system but political approval seems unlikely. The metro operates in a highly competitive public transport market including buses, Ferry Boats and small vans.

SINGLE TICKET IN THE METROPOLITAN AREA OF RIO DE JANEIRO: AN IMPACT MEASURE
2011Co-Authors: Richele Cabral GonçalvesAbstract:This paper shows how the Single Ticket implementation policy was elaborated in the Rio de Janeiro metropolitan area, and explains why it must be viewed as an important mechanism for social inclusion based on investing in transportation. The Single Intercity Ticket (BU) is a fare policy that permits the use of five different regulated transport modes (bus, train, subway, Ferry Boats and vans), using a single integration fare and fare limitation. The BU can be seen as a social inclusion factor through transport, by direct subsidy of the state government in the value of fares to intercity transport customers

EA Framework : ports and Ferry Boats stages, Corridor 3, phase 2
2008Co-Authors: VietnamAbstract:The development objective of the Northern Delta Transport Development Project for Vietnam is to support sustainable economic growth and inclusive development in the Northern Delta Region by increasing the efficiency of transport infrastructure in an integrated and safe manner. This environmental assessment (EA) document consists of a number of recommendations and includes mitigation measures of potentially negative impacts in the following areas : fishery, agricultural productivity and livelihood of project affected peoples (PAPs); surface and ground water quality; mineral resources; occupational and public health, and safety hazards due to workers operating heavy equipment and machinery; air quality; dust and noise pollution; erosion and deposition of segment of rivers caused by the construction of groins (dykes); terrestrial habitats; protected wetlands; aquatic flora and fauna; dredging operations; method of disposal of construction waste; screening will be done for workers to prevent spread of disease to the local community; and finally, the use of illegal drugs will be strictly prohibited in the construction site to prevent the spread of HIV and other possible social problems. Mitigation measures includes: (a) construction site should practice segregation and waste minimization. All materials that can be re-used and recycled should be segregated and sold. Residual wastes that cannot be recycled or re-used should be collected and disposed of in the municipal or city landfill; (b) possible sources of pollutants from construction camps are wastewater from the workers accommodation and contamination from spilled lubricants and fuel from equipment repair yard and fuel depot. To prevent contamination from these sources the workers quarters should be provided with sealed septic tanks. While the equipment repair yard and the fuel depot should be provided with impervious flooring, containment wall and floor sump to collect oily wash water and to allow separation of solids; and (c) the level of turbidity generated by dredging is partly dependent on the type of dredge used. To minimize turbidity, hydraulic cutter head suction dredge will be used.
