Haptic assistance to mitigate damaging vertical accelerations of small ships in head waves

Crew of small fast ships often experiences excessive vertical accelerations when sailing in waves, leading to discomfort and injuries. In an attempt to avoid this, experienced operators reduce speed voluntarily when they anticipate that the next vertical peak acceleration will be unacceptably large. However, at night and during excessive spray,...

Effecten van stapsgewijze aanscherping CO2-zuinigheidsgrenzen voor autobelastingen

Autobelastingen gebaseerd op CO2-uitstoot De aanschafbelasting BPM is sinds 2013 volledig gebaseerd op de CO2-uitstoot van personenauto’s. Consumenten blijken gevoelig voor belastingkortingen en vrijstellingen gerelateerd aan de CO2-uitstoot. De afgelopen jaren zijn Nederlandse autokopers gemiddeld steeds kleinere, lichtere en zuinigere modellen...

The effects of CO2-differentiated vehicle tax systems on car choice, CO2 emissions and tax revenues

This paper assesses the impacts of a CO2-differentiated tax policy designed to influence car purchasing trends towards lower CO2 emitting vehicles in the Netherlands. Since 2009, gasoline and diesel cars up to 110 and 95 gram CO2 per km are exempted from the vehicle registration tax (VRT). In addition, in 2010 a first step was implemented to...

The curious case of selecting and ranking GHG mitigation measures in transport

Marginal abatement cost curves and cost-effectiveness estimates for transport CO2 emission mitigation measures are useful tools and widely accepted for policy-makers for displaying a range of available emissions reduction options, their cost-effectiveness and reduction potential. However there is a large variety in outcomes which consequently...

Developing low carbon policies for road transport in Poland

This paper presents the results of work done for the World Bank to develop low carbon policies for road transport in Poland. Here, we outline the development of Green House Gas (GHG) emissions, develop a Business As Usual (BAU) scenario based on social-economic-, infrastructure-, car market, vehicle stock-, fuel use, and technological...

A supply-driven construction industry for transportation infrastructure New opportunities for consulting engineers

As the traditional demand-driven construction industry is currently changing, several trends point in the direction of an alternative construction industry that is supply driven. A supply-driven construction industry implies a radical change from a responsive pull market to a proactive push market. Since a supply-driven construction industry has...

A comparison of advanced cycle gas turbines with medium speed diesels in cruise ship applications

This year for the first time a cruise line has opted for a (combined) cycle gas turbine plant as opposed to a traditional diesel plant for its newbuildings. Among the generic advantages offered by gas turbines are high power density, low emissions, low noise and vibration levels, low lubricating (lub) oil consumption and reduced engine room...
