KAPPEL PROPELLER TESTED FOR CONTAINER SHIP AND FERRY DESIGNS

The Kappel propeller, sometimes known as the tip fin type, has recently been tested for two significant ship projects - a feeder container vessel and a fast full-displacement ferry. The test programme for a Kappel propeller intended for a conventional container feeder ships consisted of open-water self-propulsion tests, as normally carried out for a commercial propeller design. The Kappel type showed an open-water efficiency gain of 3.3% compared with the conventional type. Compared with a Wageningen B-series propeller with the same design point, the Kappel model showed an efficiency gain of 7.5%. A Kappel cp propeller has been developed for a fast single-screw ferry. Model tests for this project indicated an efficiency gain of 5% compared with a conventional propeller, and around 7% compared with a Wageningen B-series design.
