1 Floating Structures Product Presentation Page1 DualDocker GmbH. Gewerbegebiet Nord 6, 5222 Munderfing, AUSTRIA Mooring System for Floating Structures

2 Floating Structures Problem Page2 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 Structures Solution Page3 Innovationen for Floating Structures 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 more collisions with quayside, other houseboats etc. No more sideways movement, the house lies damped and secure at its place, even in harsh conditions Safe up to 75 % 10 times less retention force results in: considerably lower forces on the pontoon (fixed of floating) considerably lower pontoon mooring costs (Piles, Seaflex,..) Lower total project costs! Eco Friendliness No impact on underwater world No more piles, no more concrete blocks, no more chains

5 Floating Structures Application & Installation Page5 Diagonal Lines With high damping capacity for side forces Arm are rotating freely High damping capacity in pull & push direction TOP: Installation on top of the quay/pier SIDE: Installation on the side

6 Floating Structures 100 % Capacity Increase Page6 DualDocker increases capacity by 100 %

7 Floating Structures DualDocker Advantages Page 7 Convenience Jerk-free for high standard of living Defined, fixed distance to the quay/pier No sideways movement, regardless of water level Quay Security No collisions with quay, neighbouring houseboats, etc. Reduced forces due to high damping capacity Less movement, houseboats lies damped and secure at its place, even in harsh conditions Ultra high damping to prevent collision damages Cost Reduction 10 times less force results in considerably lower overall project costs - Reduced forces transmitted on to floating pontoon - Reduced mooring forces (piles, Seaflex) Negligable maintenance costs No collisions - no repair costs for damaged pontoons Eco Friendliness No impact on underwater world No piles, no concrete blocks, no chains

8 Floating Structures Customer Feedback Yachts & Marinas Page8 Oulton Broad / Suffolk / UK, 42 Sealine Luke Smith, Dezember 2011: I am seriously impressed with the DualDocker. We have had very strong gales with gusts up to 105 km / h and my yacht lay stable and secure at her unprotected berth. She used to swing around a lot in the past, but that s history. Great! Fiorenzo Lupieri, Manager Marina Portoroz/Slovenia, January 2012: We have been testing the DualDocker in our marina for almost 6 months now. The System has convinced us, especially during storms. Our own yacht, a Princess 44, lies stable and secure at her berth. A stress test using both 550 hp engines in December was very impressive.

32 Floating Structures Damping of Kinetic Energy Page 32 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 [m/s] F braking force [N]; 1 kg=.,81 N Distance braking distance [m] Weight: 10 t v [m/s] Damp.
