Method to Install Offshore Foundations

10.10.2012
<strong>Background</strong><br>

It is still a main problem in the offshore industry to install foundations that satisfy the acoustic limiting values set by the Federal Maritime and Hydro-graphic Agency (BSH). Current methods mainly focus on passive acoustic protection during ramming that do minimize the acoustic emissions but how-ever cannot reliably observe the acoustic limiting values. <br><br> Thus there is still a need for installation methods that are easy to handle, economic and fulfill the requirements made by the federal institutions. <br><br>

<strong>Technology</strong><br> The currently developed installation method for offshore foundations can overcome the above mentioned problems from the state of the art and easily satisfy the acoustic limiting values set by BSH. <br><br> The main advantage of this method is that ramming - the main noise produc-ing installation step - is no longer necessary. With the proposed method the foundations are installed by flushing away the seabed below the foundation in a controlled way and use it for further stabilization of the foundation.<br><br> <strong>Benefits</strong> <ul> <li>Clearly lower acoustic emissions and thus satisfying the limiting values from the BSH</li> <li>Cheaper and faster than current installation methods </li> <li>Use of ferroconcrete as foundation material -> very well corrosion protection</li> <li>Use of standardized components, no customized products necessary</li> <li>Easy transportation of the foundation to the place of installation </li> </ul> <p><strong>IP Rights</strong><br> German Patent application filed in April 2012 <br> <br> <strong>Patent Owner</strong><br> Technische Universität Berlin

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

International research team makes important step on the path to solving certification problems

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
