1 Floating Hotels Product Presentation Page 1 DualDocker GmbH. Gewerbegebiet Nord 6, 5222 Munderfing, AUSTRIA Mooring System for Floating Hotels up to tons Damped, Secure & Eco-Friendly

2 Floating Hotels Problem Page 2 Chains A lot of movement at low water level High impact on underwater world Lack of Convenience Disturbing movement in windy and wavy conditions Strong jerking due to lack of dampening Lack of Security Damages during storms Damages due to flotsam Caution: No damping results in 5 times higher peak load (wind & waves) 10 times higher peak load (flotsam & collisions) Piles High impact on underwater world Lack of Convenience Strong jerking in windy and wavy conditions Lack of Security Damages due to flotsam (limited damping capacity) High Costs 2/3 of total length needs to be driven into sea/river bed Problematical in deep waters and rocky or sandy sea/river beds Quay Quay 2/3 L Chains Piles

3 Floating Hotels Solution Page 3 DualDocker Jerk-free for highest convenience No Play No sideways movement, regardless of water level High Damping Characteristics Energy caused by wind, waves, flotsam and collisions is absorbed by the DualDocker. (Big damping space results in low strain!) Pier Reduction of Forces High damping characteristics result in 10 times less retention force Security during Storms No collisions with quayside No more sideways movement, the hotel lies damped and secure at its place, even in harsh conditions Cost saving Lower installation costs Lower maintenance costs No running energy cost Lower total project costs! Eco Friendliness No impact on underwater world No more piles, no more concrete blocks, no more chains 100% mechanical, no energy source needed

9 Floating Hotels Damping of Kinetic Energy Page 9 DualDocker reduces retention force! Why? Energy created by wind & waves, flotsam or collisions must be absorbed. Degradation of energy follows a simply physical principle (force x distance) High damping (DualDocker): Long damping travel, low forces (like a crash barrier) Minimal damping (chains, piles): short distance, high forces (like a concrete wall) Additional information (calculation formulae, results): Kinetic energy: Ekin = m v² / 2 Braking force: F = 2(Ekin / distance) Ekin Kinetic energy [Joule] m mass [N]; 1 kg = 9.81 N V speed [] F braking force [N] Distance braking distance [m] Weight: 100 t v [] Damp.
