SCHOTTEL has supplied main and auxiliary propulsion units for China's first ice-breaking buoy-layer. The "Haixun 156", which will perform a wide range of tasks, was recently launched by the contracted Wuchang Shipbuilding Industry Group, Hubei Province, China. The ship was ordered by the Tianjin Maritime Safety Administration (MSA) and is scheduled to enter service in September 2021.

SCHOTTEL EcoPeller for China's first ice-breaking buoy layer

SCHOTTEL drive package

The ship's main drive consists of a pair of diesel-powered SCHOTTEL EcoPellers type SRE 460 (1,800 kW each) with a 4-bladed propeller and a diameter of 2.4 meters. To improve maneuverability and offer DP capabilities, the new building is also equipped with a SCHOTTEL TransverseThruster Type STT 1 (500 kW). With this drive configuration, the ship reaches a free speed of 14.5 knots.

The azimuth drives of the "Haixun 156" are ice-reinforced according to the Chinese ice class CCS 2 (corresponds to the Finnish-Swedish ice class 1B). This enables the ship to break through ice up to 0.6 meters thick and to carry out emergency measures under extreme weather conditions in the northern Chinese waters. Maximum maneuverability is particularly important when used in ice.

Highly efficient, sustainable, versatile

Thanks to the particularly powerful combination of powerful propeller thrust and course stabilizing fin, the SCHOTTEL EcoPeller meets all the requirements of a modern high-performance drive. Thanks to its hydrodynamically optimized design, the EcoPeller generates the highest steering forces and enables top values ​​in terms of overall efficiency and course stability. This reduces fuel consumption and ensures lower operating costs and emissions.

In action for the Navigational Security Center

With a length of 74.9 meters and a width of 14.3 meters, the ship has a displacement of 2,400 tons. "Haixun 156" is used for the installation, removal, replacement and maintenance of navigation aids in ports and on shipping lanes in northern China.

The AtoN ("Aids to Navigation") system in the port of Tianjin is tight and developing rapidly. It is responsible for maintaining all navigation aids in the Tianjin area.

About the Port of Tianjin

The Port of Tianjin is the largest port in northern China and the main maritime gateway to Beijing. It is the largest man-made port in mainland China and one of the largest in the world. It extends over an area of ​​121 square kilometers, with over 31.9 kilometers of coastline and around 151 production berths.
