Four newly built Wind Turbine Installation Vessels (WTIVs) for Ouyang Offshore in Shanghai will all be propelled by Schottel azimuth thrusters, with the first vessel to be delivered in the last quarter of 2022 and others to follow by June 2023.
The new vessels have been designed to cover the installation of 16 MW wind turbines. Each will be equipped with two electrically-driven type 430 Schottel RudderPropeller azimuth thrusters and two Schottel STT4 TransverseThrusters to ensure DP mode manoeuvrability and precise positioning.
Schottel says that its SRP RudderPropeller has proven itself over a 70-year timespan as a universal all-rounder in a variety of ship designs and areas of operation. The 360-degree steerable SRP combines manoeuvrability and bollard pull with course stability during free sailing to provide powerful thrust in the chosen direction.
The 90m long and 42m wide WTIVs will be able to operate in a working depth of up to 60m. They have accommodation for up to 100 people, on board to install offshore wind turbines and conduct maintenance work.
Schottel acknowledges the importance of the People’s Republic of China as one of the largest shipbuilding nations. As such, the German propulsion company has four sites in China: Suzhou, Shanghai, Dalian and Guangzhou. This offers customers fast service on site and at their premises.
