Floating systems ship Peter Pan
Our customer German Dry Docks required a total buoyancy of 950 tons of inflatable
float systems for their operation, to be designed, engineered,
produced and erected within 2 months.
This floating system is applied to temporarily lift the stern of a
ferry and have floating. German Dry Docks has an assignment to
enlarge an existing ferry. The ship is cut in half, the back end of
the ship is moved out and later on back into the dock in order to
weld a new part in between the two existing parts.
Inside the dock insufficient space was available to use steel
pontoons as well as insufficient capacity of the hull to carry the
steel pontoons when the ship was lifted out of the water. It needs
sufficient surface area on the hull to fit on the pontoons.
Below pictures explain the inflatable float systems project. In
this example the stern remains in the dock while the bow is
navigated out of the dock.
1.2 Design and engineering
We developed the inflatable float systems and sized the cushions
in close cooperation with German Dry Docks.
During engineering we took into account:
- required buoyancy
- maximum inclinations
- force on the attachment
- tension in the tubes
- maximum inflating pressure
- available budget
Finally the project route resulted in:
Floaters Type 1: 8 floats with a diameter of 2
meter and a length of 34 meter. Each inflatable float has a buoyancy of 100

Floaters Type 2: 8 floats with a diameter of

Supervised and assisted by Buitink Technology the floaters were
connected to the ship. Manifolds and air compressor systems were
connected and the floats were pressurized to make the system
The stern of the ship was floating during 10 days carried by
Buitink Technology delivered floating system.
During the course of the operation Buitink Technology was
responsible for a 24/7 surveillance of the system. We took care of
the correct air pressure inside the cushions.
