3 years of offshore experience with more than 1000 designed hose rings ensures constant Big Bubble Barrier optimization. A suggestion for improvement comes from an offshore team at least every 4 weeks. Laying on the seabed and hauling in is constantly improving. For example, when hauling in the bladder tube, a large amount of mud ran onto sensitive parts of the hose winch. The team reacted and had the local blacksmith make a sheet metal for them during the next port visit, which now protects these parts. A topic that only becomes visible during use.
What really sets us apart is that our on-site colleagues have been with us for 3 years now. You have gained immense experience in this field. This is very important in order to be able to react to the ever new challenges.

Skilled engineers strengthen the team
After 3 years of using the Big Bubble Barrier, more basic research is being carried out again. The HYDROTECHNIK LÜBECK team now includes students from various technical universities. As part of your master’s thesis, you will examine, for example, the hose material or the ascent speed of the bubbles.
These skilled engineers help me a lot in my work. The areas that are relevant to us are marked for me from the specialist literature. I save time and can concentrate on the essentials.

The public sector’s interest in the further development of the bubble veil has meanwhile expired. Funding is no longer available, although the potential of bladder technology is far from being exhausted. The limit values are adhered to, but there are fluctuations in the measurement results that no one can explain.
Measurement results are depending on the amount of air, the air pressure that is put into the hoses, the nature of the ground, the current, and of course on the ramming energy with which the pile is driven into the seabed.
Optimization gives more security
To obtain more security, HYDROTECHNIK LÜBECK continues to optimize the bubble curtain on its own. The measurement results got better and better over the years. In this way, the installation vessels can increase the ramming energy and still comply with the guide values. The duration of the pile driving is reduced. That is a contribution to environmental protection.
