Towing System: .................................Multraship Carousel

After introducing the Carrousel concept about a decade ago, Multraship invested signi? cant time and effort into the development and re? nement of the concept. This in- cludes the development of a fully functional prototype tug with which all sorts of tests and experiments, as well as many hundreds of real ship assists were performed. This research and testing has led to a clear grasp of the full spec- trum of operational possibilities and bene? ts of the Car- rousel towing system, with the ultimate aim to come up with the basic blueprint for a tug design which is opti- mized for it. Inline propulsion was always clearly envisaged in that context, and the ultimate marriage of this unique safety device to the outstanding performance of the RAVE hull and VSP propulsion system promises to move tug de- 45 www.marinelink.com MN
