In addition to proven technologies such as the Dynamic Positioning System and azimuth thruster (360-degree propeller), we support emerging technologies like jacking systems and super-large cranes for the management of every type of offshore vessel.
Offshore Wind Turbine Installation Process
Loading offshore wind turbines on a SEP ship
After entering the port, offshore wind turbines are loaded onto the SEP.
The typical length of an 8MW offshore wind turbine is approx. 80m for blades and 105m for a tower.
Jack-up and setting
The SEP moves to an installation point where it is elevated with four feet while being positioned by the DPS before commencing turbine set-up work.
Jack-down
After the installation of the turbine, the SEP is jacked down and moves to the next installation point.
Installing the other turbines
The above steps are repeated to install the other turbines at their respective installation points.
