ULSTEINVIK, Norway – Ship designer Ulstein Design & Solutions BV says that it has introduced a safer, smarter and more competitive solution for transporting, upending and installing large monopiles using dynamic positioning.
The company says that its U-STERN system enables longitudinal storage of monopiles and upending in the ship center line. This allows the ship to head into the waves during the installation process, thereby minimizing ship motions and fuel consumption, while still providing shielding from waves.
Ulstein say that by combining the U-STERN with transverse and longitudinal skidding systems, offshore lifts for monopiles are eliminated, as the main crane is only used to support the upending and lowering of the foundation.
