NGC Successfully Completes Dynamic Positioning Sea Trials for Propulsion System Matched for Singapore Marine Ship

Recently, the subsidiary corporation of NGC Marine Group鈥斺�擭anjing High Accurate Marine Equipment Co., Ltd (鈥淣anjing High Accurate Marine鈥�) successfully completed sea trials for the primary propulsion system, including controllable pitch propeller and controllable propeller gearbox matched for 65m AHTS (anchor handling towing supply) of Singapore Miclyn Express Offshore, and finished the dynamic positioning sea trials. In recent years, after accumulating experience in terms of multiple dynamic positioning marine ship projects, Nanjing High Accurate Marine has become a unique equipment supplier able to completely grasp propulsion system design and seal trail technology of the dynamic positioning ships amongst domestic brands. The ship is the leading ship of the series built by the Wuchang shipyard and exported to Singapore; with the successful sea trails and delivery in batches of those ships, the products representing Nanjing High Accurate Marine are gradually entering the Singapore marine ship market.

figuration of dual-machine dual-propeller. Classification society is ABS, host is import Daihatsu, and the product has power of 2666kW. The design requirements of the project are that the thruster be capable of producing 90T of bollard pull power in standard sea conditions when the host power is 100%, with a maximum ship speed of 13Kn. After the sea trials were tested onboard, the bollard pull power of the ship was found to rise to 92T, and the ship speed rose to 13.4Kn. As the two most important design indexes of the anchor handling towing supply, the bollard pull power and the ship speed exceed the designed values. The project is highly automated and meets the requirements of DP2 and FMEA. The pitch time of the controllable propeller provided by Nanjing High Accurate Marine is short and the accuracy is high, so that the controllable propeller can perfectly work when matched with DP2 system, and the FMEA requirements can be perfectly met. The ship owner gives a good review.

The successful sea trial of 65m AHTS once again shows that Nanjing High Accurate Marine has the full capacity of packing and exporting ship thrusters and the gearboxes in the field of marine engineering ships, and the technical level of its products reach international advanced levels.
