High Accurate Marine Company got an order of tunnel thruster for 8000KW ocean salvage vessel

Nanjing High Accurate Marine Equipment Co., Ltd (High Accurate Marine Company), a subsidiary of NGC signed a contract with Ministry of Transport regarding bow/stern thrusters of three 8000KW ocean salvage vessels, i.e. 9 units of NCT165 controllable pitch tunnel thrusters in total.

The missions of ocean salvage vessel are to rescue the people from the vessels in danger and to help the vessels with the purpose of ship salvage, and other salving operation, such as towing, fire fighting, and so on; what鈥檚 more, they are capable of night search, hatch sealing, leak stoppage, water discharging, air diving, etc as well. One of these three vessels in the order is featured with ice breaking.

Before this, the tunnel thruster for the domestic ocean salvage vessels were all imported. This contract broke the monopoly of equivalent foreign products in domestic ocean salvage market.

NCT CP Tunnel thruster

High Accurate Marine Company is an advanced company in Asia, which is specialized in R & D, manufacturing and service of marine transmission and propulsion system. The product covers controllable pitch propeller (maximum diameter 6.8m), fixed pitch propeller (maximum diameter 11m), azimuth thruster, tunnel thruster, marine standard/non standard gearbox, hydraulic coupling, spiral bevel gear and stern tube components. The technology and performance of the products are ranked in the same level as the equivalent products in international market. Several products have filled up the gap of domestic market.
