Over the course of the last years TWO developed an advanced friction measurement method and probabilistic verification of monopile stability during transit. Both have now received certification from DNVGL. This sets a new standard in monopile seafastening.
Seafastening of future monopiles on heavy lift installation vessels becomes an ever-increasing challenge. One challenge is verification of monopile stability on its supports at high vessel accelerations. With this recently certified method, engineers at TWD are able to increase the workability of designs, while making them safer and more cost-effective.
The optimized methodology results in the ability to increase workability by 20-50% whilst maintaining the highest safety standards.
The offshore wind industry ventures into unexplored territories where severe environmental conditions become the new standard. TWD can use the developed method in future projects related to transatlantic transport or in areas where installation is more challenging than the north sea. TWDs verification method and friction test set-up makes the difference in guaranteeing the stability of monopiles of the future during transit.
