ROPES is a joint industry project aiming at providing the partners with software to compute the forces induced by a passing vessel on moored vessels. Both Flanders Hydraulics Research and Ghent University joined the project for € 1 and are committed to the Antwerp Port Authority being an industrial partner in the project. The Antwerp Port Authority wished the software would take account of the specific situation in the harbour of Antwerp:
The traffic in the Deurganck and the (yet to be built) Saeftinge docks where large sailing container carriers interact with equally large moored container carriers;
The setup of jetties on the river banks and in the docks to moor tankers that also will be affected by the passing ships;
The interaction with smaller (inland) vessels.
To enable the validation of the software with the above conditions FHR wrote a research proposal  to the ROPES’ steering committee. Due to budget restrictions the accepted proposal, further referred to as proposal A, is only a reduced version of the initial one. For this reason the Antwerp Port Authority asked for an additional program , which will be referred to as proposal B. None of these proposals took account of the effect of a moored ship with an extremely small under keel clearance. Model tests addressing this issue are covered by a 3rd program C .
This report is the fourth one in a row and covers the tests carried out in February and March 2012.
