SVA Fin System

The shipping world was extremely influenced by the so called oil crisis at the beginning of the 1980^th. In that time all over the world were developed new ideas for reducing the oil consumption of ships.

One of these ideas was the so called SVA Fin System, a hydrodynamic Energy-Saving Device. The Inventor was Dr Hans-Erhard Peters; I was involved in the development and optimisation only.

The design goal of the SVA Fin System is the reduction of the

• Rotational losses in the slipstream via the fin
• Partially reduction of losses in the ships wake via special fin design

The realistic possible power reduction lies between 2 and 4 %.

The SVA Fin System has been realised in full-scale fife times alltogether, three times at container ships (corresponding patent No 1), and at two inland vessels (corresponding patent No 2).

The proved power reduction in full-scale was about 3 % for the container ships; and about 9 % for the inland vessels.
