NASDIS is currently involved in the Conceptual Design and Class Documentation of a 10000 tons Floating Platform/Dock. The project is done for STX RO Offshore Tulcea and under approval with Bureau Veritas. The Floating Platform/Dock with controllable ballast is an integrative type, built up with a continuous bottom pontoon and partially extended side towers. The pontoon is divided in ballast tanks, void technical spaces for pumps, piping and two recesses to test the retractable thruster of a ship. Purpose: the transfer of the ships from the syncrolift to the platform and from the platform to the syncrolift, building a ship with up to 40,00m breath, mega blocks erection, launching/lifting and repairing ships.
