The tests, designed to shed light on both the physics and the practicalities of moving the GBS in varying ice conditions where towing force and structural stability, influenced by ice resistance are central for a successful platform design. The current model test is the first...

... Abstract The air bubbling system for use in reducing ice resistance of icebreaking ships was introduced in late 1960ies. After extensive development and testing the system has been used in several vessels till early 1990ies. The idea of the system is to blow compressed air down in the bilge...
