Liquid-cooled drives for re-modelled Seili

摘要

Since March 2004, the Finnish Maritime Administration waterways service vessel Seili, which earned a place in history as the first ship to be fitted with an ABB Azipod propulsion plant (The Naval Architect June 1992, page E307), has been sailing again in the Gulf of Finland, powered with Vacon liquid-cooled main propulsion drives. During a nine-month rebuilding project at the Aslemetals yard in Olkiluoto, near Rauma, Seili was modified into a genuine multi-purpose vessel. After altering and lengthening the vessel with a new hull section 7.8m long (to make a new waterline length of 48.60m), the ship is now capable of oil-spill response functions, with two 98m' collecting tanks, and is believed to be the first in the world capable of oil collection in icy conditions. Seili can also be used for icebreaking as well as for various transport and supporting pilot functions in heavy ice conditions.
