Next NMS-6000 Riffgrund operational 01-2014 Pile integrity by integrated functionality
Each contractor is not only using a piling hammer.
A lot of tools and equipment is involved, consuming: • Deck space • Operators • Energy • Controls • Handling time • Costs • Etc…………..
Combining functionality in one piece of equipment is: • Speeding up the installation • Increasing workability • Ensuring accurate installation • Eliminating risks • Reducing costs

Next Generation NMS & Installation Equipment Research - Develop - Test - Innovate - Research - Develop - Test - Innovate
NMS Improvements
Thanks to FLOW support knowledge and experience is gained during the installation of the Riffgat project. Resulting in the next generation NMS with improved mitigation of approximately 9 dB. The overall under water noise mitigation is expected to be 20-29 dB on the SEL at 750 m.
Cost reduction by: ! Increased workability ! Enlarging the weather window ! Integrated installation tools more functionality ! Less risk ! Safety & comfort for crew ! Contingency by HiLo piling option ! Fatigue reduction piles 30-60% ! Fatigue reduction equipment ! Optimized pile design (by less fatigue to pile during installation) ! Reliable proved installation method (1782 foundations 1.82 – 6.5m) ! No down time (proven design and technology)
