Title: Experimental study into the mining of coarse sand by undercutting of a fine sand layer Client: fa. Zeldenrust An experimental study into different methods for the undercutting of fine sand by means of a plain suction dredger and the application of in-situ separation of sand particles through fluidisation. Experiments in the laboratory have been carried out to gain a qualitative insight into the in-situ separation of sand particles for different extraction methods. Finally a conceptual design of the excavation tool has been developed.

Title: Dredgeability study for a dredge mining project Client: Southern Era Resources Evaluation and dredgeability study for a diamond deposit in Southern Africa. Several large batches of core samples were tested on dredgeability to assess possibilities. Based on this sample testing and further evaluation of the project constrains, several scenarios for possible dredge operations were analysed. This also included the directly connected pre-processing unit. The dredgeability study is used completely as an add on to the feasibility report for the envisaged dredge mining operation.

Title: Framework for the set-up of a Research and Engineering Research Centre Client: PT Timah This study aimed at the set-up of an Offshore Research and Engineering Centre for PT Timah - Indonesia. First a site visit to evaluate possibilities for modernisation of an offshore tin mining operation (dredging and processing) was carried out. This was followed by a set-up of a frame work for the set-up of the Centre, evaluation of objectives, required organisation, first planning of the establishment and analysis of the required research and engineering topics to be carried out by the envisaged organisation. Balancing requirements, resources and time frames led to a budget indication for initial investment and operating costs for the first 5 years.
