A high-profile dry dock project in Romania utilised the skills of Unique Group’s Buoyancy & Ballast division and the supply and operation of 840t of Seaflex inflatable buoyancy.
The hull and lower decks of the Australian Antarctic Division’s (AAD) new icebreaker Nuyina (which means ‘Southern Lights’ in palawa kani, the language of Tasmanian Aborigines) were constructed in the dry dock at Damen’s Galati Shipyard. For the next phase of construction, the installation of the upper decks, to take place the dry dock needed to be flooded and the hull then towed to the wet dock.
Detailed engineering discussions took place over 18 months ahead of the work to determine the sizing, positioning and securing of the buoyancy units to the hull, so as to ensure sufficient clearance between the sill of the dry dock and the keel of the vessel when the dry dock was flooded.
42 x 20t Seaflex Inflatable Buoyancy Units and a system of hoses and manifolds were supplied to Damen on a rental basis, and two Seaflex technicians were deployed to offer
on-site support throughout the two-week operation which took place during the early autumn of 2018.
