Schottel to supply propulsion for China’s first ice-breaking light buoy tender

Schottel has supplied main and auxiliary propulsion units for China’s first ice-breaking navigation aid tender vessel.

Schottel has supplied main and auxiliary propulsion units for China’s first ice-breaking navigation aid tender vessel. Haixun 156, which will perform a wide range of tasks, is a 74.9m long vessel that has recently been launched by the Wuchang Shipbuilding. It was ordered by the Tianjin Maritime Safety Administration (MSA) and is scheduled to enter operation in September 2021.

It will be deployed for setting up, removing, swapping and maintaining navigation aid facilities at ports and on navigation routes in North China.

The main propulsion of the beacon vessel consists of a pair of diesel-driven Schottel EcoPellers type SRE 460 (1,800 kW each) featuring a four-bladed propeller with a diameter of 2.4m. To enhance manoeuvrability and provide DP capabilities, the new build is equipped with a Schottel TransverseThruster type STT 1 (500 kW). With this thruster configuration, it reaches a free sailing speed of 14.5kt.

The azimuth thrusters of Haixun 156 are ice-strengthened according to Chinese ice class CCS 2 (corresponding to Finnish-Swedish ice class 1B). This enables the vessel to break through ice as thick as 0.6 metres, guaranteeing emergency responses in North China’s waters even under extreme weather conditions. Especially when operating in ice, maximum manoeuvrability is of particular importance.
