SUPERPROP

EUROPEAN FP6 EU R&D PROJECT “SUPERPROP”

canal.etsin.upm.es/superprop

The consortium has been formed by:

  • CEHINAV-ETSIN-UPM (Spain)
  • PESCANOVA (Spain)
  • C.N. P. FREIRE (Spain)
  • SISTEMAR (Spain)
  • INSEAN (Italy)
  • FUNDILUSA (Portugal)
  • VTT (Finland)
  • MARINTEK (Norway)

The test cases for the study have been the trawler “ILA” from PESCANOVA and the Italian tug “VAL” from OCEAN. SISTEMAR designed a CLT propeller for the trawler and the improvement obtained in the efficiency over the former conventional propeller has been in the range of 5%.

The project is focussed in obtaining the optimum method for updating old ship propellers from technological and economic points of view, in order to improve the fuel consumption rates and reduce the maintenance costs. The objectives of SUPERPROP are:

  • Most fixed pitch propellers installed on fishing vessels are Marin B-series. Results from methods for recovering shaft speed to the whole B-series calculated using CFD codes and model tests will be obtained, as well as cavitation predictions.
  • Development of an economic strategy to predict the profitability of propulsion updating in old fleets.
  • Improvement of the knowledge about the state of the art in old ships propulsion and their ageing.
  • Thrust the knowledge in correlation methods to extrapolate results obtained from model testing to full scale.
  • To apply CFD codes to predict propeller behaviour, to collate computational and model testing results and to estimate prediction accuracy of both methods.

The main innovative features of SUPERPROP are:

  • To study economic profitability of old fleets and the saving that could be reached in fuel consumption, machining maintaining and contaminant gases emission.
  • To use extensively full scale measurement for improving propulsion efficiency.
  • Development of a strategy to reuse old propellers with low cost by means of machining or deforming to readjust it to new working conditions.
  • Scientific and Technological Prospects :
  • SUPERPROP addresses important research aspects in the areas of economic impact of ageing effect in old ships, marine propeller design, CFD modelling of propeller flow and scaling of propeller model test performance data to full-scale predictions. All these research achievements will be transferred into design tools, procedures and databases that can directly be applied in practical propeller design.
