Chains

Piles 2/3 L

Floating Pontoons Page 2 Problem

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 & Security • Strong jerking in windy and wavy conditions (loose piles)

• Overload damages due to 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

Innovation for Floating Pontoons

• Jerk-free for highest convenience

• No Play

Limited 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!)

• Reduction of Forces

High damping characteristics result in 10 – 20 times less retention

force

• Security during Storms

No more collisions with quayside. The Pontoon lies damped and

secure at its place, even in harsh conditions

• Safe Money

20 times less retention force results in considerably lower forces

Lower overall project costs !

• Eco Friendliness

No impact on underwater world

No piles, no concrete blocks, no chains/deadweights

Convenience • Jerk-free

• Damping without play regardless of water level differences

Security • No collisions with quay

• Reduced forced due to high damping capacity

• Less movement, pontoon lies stable even in harsh

conditions.

• Ultra high damping to prevent collision damages

Cost Reductions

• 20 times less force results in considerably lower

overall project costs.

• Negligable maintenance costs

• No collisions, no repair costs

• No adjusments of chains, concrete blocks or piles

Eco Friendliness • No impact on underwater world

• No piles, no concrete blocks, no chains
