High-pressure underwater jet-cutting (Water Abrasive Suspension, WAS) is an effective method to disassemble underwater structures. Because jet-cutting tools do support a very flexible configuration, even complex tasks like cutting piles below the sea-bottom from inside-out, can be handled. However, up to now the cutting of multi-layer piles causes a problem because a.) fluid-filled voids in the concrete layers may absorb the energy of the cutting jet, and b.) tools to remotely supervise the cutting process and confirm its success are not available yet. CoCut will improve state-of-the-art WAS tools to enable the efficient and reliable underwater cutting of multi-layer piles. The new tools to be developed in CoCut will include devices to create an in-situ habitat with close-to-atmospheric conditions, sensors to transmit visual and acoustic signals to the operator, and signal-analysis software to automatically control the cutting process and to confirm the success of a cut. The new CoCut technology will greatly enhance the reliability, efficiency and quality of underwater cutting operations. It will allow the cost effective dismantling of complex layered structures, such as multi-layer strings used in oil-rigs, conductors and other offshore facilities, at depths up to several hundred meters and below the sea-bottom. Partners for the development of CoCut ANT Applied New Technologies AG (http://www.ant-ag.com/) has many years of experience in underwater jet-cutting and is producer of highly efficient, state-of-the-art Water Abrasive Suspension (WAS) jet-cutting equipment. ANT?s field-proven cutting tool AMU 2500-100 will be the basis for the new CoCut underwater jet-cutting system. ANT will improve this system with a nozzle for cutting of piles inside-out. ANT will also develop a new system to create an in-situ habitat with close-to-atmospheric conditions to allow for effective cutting of multi-layer piles. The Robotics-Lab of the DFKI German Research Center for Artificial Intelligence (http://www.dfki.de/robotics) has extensive expertise in underwater robotics. The DFKI develops, among others, sensor-based software solutions for the user-friendly, intelligent control of ROVs, deep-sea robotic manipulators and other underwater equipment. In CoCut, DFKI will develop the signal analysis tools and sensor-based control software for the CoCut system. Speakers at UWT 2010 ?
