Title: | WABS; a system for improving the icebreaking performance of ships / Wärtsilä (Helsinki) Shipyard. |
Author (corporate): | Wärtsilä (Helsinki) Shipyard. |
Date: | 1979. |
Publisher: | Helsinki: Wärtsilä |
Abstract: | Describes Wärtsilä air bubbling system (WABS), first installed on ferry m/s Finncarrier in 1969. Provides method of hull lubrication which reduces friction between hull and ice or snow. Has now become standard equipment on icebreakers and merchant ships designed for operation in ice without icebreaker assistance. Inserted update shows that system has been installed in, or ordered for, 55 ships. |
