Floating systems ship
Our customer 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. This customer 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 this client.
During engineering we took into account:
- required buoyancy
- buoyancy distribution
- 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 tons!
Floaters Type 2: 8 floats with a diameter of 2,4 meter and a length of 4.5 meter
We solve it with a lightweight flexible solution!

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 operational.
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.
