1107304/-05 Ocean Space Centre K664-01 Movable Floor (OB and SMB).

Description

Ocean Space Centre (OSC) shall be located at Tyholt in Trondheim, Norway. The Centre shall contain research and higher education institutions operating under one roof, seamlessly integrating basic and applied research areas in marine engineering and life sciences. Once completed, OSC shall consist of a unique selection of laboratories with simple and robust student laboratories, highly advanced laboratories for basic research, some of the world's largest hydrodynamic laboratories for large-scale and industrial research, and full-scale field laboratories in the fjord and marine areas outside Trondheim. All this combined with advanced computational and numerical facilities. The new laboratories shall replace the existing facilities currently located at Tyholt in Trondheim. Lot 1: The ocean basin (OB: 50 x 60) and the rough sea basin (SMB: 180 x 40 m) will both be equipped with a moveable bottom system that can be lowered down in the water, adjusted, and locked in the entire depth from; 0-12 m for OB and 0-6 m for SMB. The bottom has extraordinary high requirements for structural stiffness, dimension tolerances, positioning, and operational performances, and is a key in the realisation of the ambition related to hybrid testing in the basins. OB: The moveable bottom covers almost the entire area of the basin, with an adjustable inclined plane that stretches towards wave machines and the incoming current on one side and the outflow and wave absorbing bars in the other end. The moveable bottom in the ocean basin will, in addition, have a central section (centre hole) of L7.5 x B7.5 x D14 m, equipped with a steel construction that can be further sunken or raised to the desired height in or above the centre hole and locked to the walls. The moveable bottom is built up as a stiff steel construction, consisting of a beam system laid on pillars that go into dedicated shafts in the bottom of the basin. SMB: The moveable bottom in the SMB will cover a section of the basin with a bottom area of 40x50m. The floor construction and the supporting pillars for this floor have an equivalent design as for the OB, but without a deeper central section and adjustable inclined plane. A lot of the assembly work must be carried out on-site, including welding and surface treatment due to the moveable size of the two systems.
