Recently, the research ship Xiangyanghong 28 successfully passed its sea trial. The propulsion system with fixed pitch propellers was transformed into a propulsion system with adjustable pitch propellers by Nanjing High Accurate Marine Equipment Co., Ltd. (hereinafter referred to as 鈥淣GC Marine鈥�), a subsidiary of NGC, which satisfies the low-speed sailing requirements for scientific investigations. With 74.55 m in length and 10 m in width, the research ship Xiangyanghong 28 was driven by two low-speed diesel engines, which were manufactured in the 1970s. Such engines were connected to the thrust bearing and the fixed pitch propellers with the pneumatic tube clutch. The original shafting vibrated violently in operation, and the torque transmission capacity of the pneumatic tube clutch decreased. Following repeated demonstrations and analysis with the owner and the manufacturer as well as field investigations, NGC Marine determined to reserve the original engines, and replaced the pneumatic tube clutch with a gearbox with a built-in hydraulic clutch and thrust bearing. In addition, a high-elastic shaft coupling was installed between the gearbox and the engine. In order to satisfy low-speed sailing during scientific investigations, the fixed pitch propellers were replaced by adjustable propellers. With the advantages of low cost, high efficiency, and less transformation work, this solution was accepted by the owner and the manufacturer. Meanwhile, NGC Marine designed a new oil distributor for small-sized adjustable propellers, which successfully resolved a series of technical ...

The sea trial of the 8000HP deepwater towing/anchor handling/supply vessel (marine oil 641) was recently commenced. The main propulsion system was designed and produced by Nanjing High Accurate Marine Equipment Co., Ltd., a subsidiary of NGC Marine. The trial voyage over many days showed that the performance and velocity of the main propulsion system satisfied vessel design requirements. The bollard pull test conducted at the Huangchuan Wharf in the Nansha Islands attested to the fact that the bollard pull was greater than vessel design requirements under 100% MCR power. With the propeller and axles of the main propulsion system running smoothly and the pitch-controllable precision reaching internationally advanced levels, the sea trail achieved complete success and received the positive acknowledgement of the owner. The vessel was successfully delivered on June 19, 2015. An 8000HP deepwater towing/anchor handling/supply vessel is one category out of 5 types of 14 ships under construction by China Oilfield Services, among which two were simultaneously constructed by Cosco Shipyard in 2014. In addition, domestic propulsion systems were first applied in China Oilfield Services vessels. To facilitate the vessel better achieving the need to fulfill new marine tasks, the main propulsion system adopts the double controllable-pitch propeller with a fairwater structure and 4 medium-speed diesel engines.Designed by SDARI, 8000HP deepwater towing/anchor handling/supply vessel features long axles and stern tubes. The propulsion system is equipped with four engines and two propellers w...

Nanjing High Accurate Marine Equipment Co., Ltd. (High Accurate Marine), a subsidiary of NGC Marine Group, recently received an export order for 20 sets of azimuth thruster propulsion system for ten 鈥�42T bollard pull azimuth tugboats鈥� registered by American Bureau of Shipping. The contract for this order amounts to nearly RMB 40 million. The main propulsion system of the ASDs tugboat is composed of Caterpillar CAT3512C diesel engines and High Accurate Marine鈥檚 NRP180 azimuth thrusters.
