The goal of the EU project MoVe IT! is to develop a suite of options for the modernisation of inland ships that meet the challenges of over-aging of the fleet, climate change and stronger environmental objectives and provides decision support regarding the application of these options.

In WP1 the state of the art is defined by means of a literature study and by means of full scale measurements on board of five inland vessels. The goal of the measurements is to determine the performance of existing vessels in a controlled environment. Measurements have been done on board of five inland vessels and the performance of the selected vessels has been determined. For the vessels that perform below average CFD calculations have been performed within WP2 to determine the effect of retrofit measures. The results and analysis of the CFD calculations are presented in this report.
From the CFD calculation results a reduction in power due the retrofit measure will be retrieved. This is input for WP7 system integration and assessment.

The measurement results performed in WP1 showed that all vessels, except for the Veerhaven X pushboat were performing below average. For all vessels performing below average CFD calculation have been performed to investigate retrofit measures.

Each case had different aspects had to be investigated, therefore for each case a computation program was selected most suitable for investigating the retrofit measure. Since CFD calculations are a simulation of reality some simplification have to be taken into account. In the section of the CFD analysis of each vessel is written what simplification have been made to perform the calculations.

This report is divided into 4 Sections. In Sections 1 thru 4 the CFD calculation analysis of respectively Carpe Diem, Herso-I, Inflexible and Dunaføldvar are shown. Finally an overview of all the conclusions is presented.
