According to the special requirements of the marine engines, basing on the golden medal Z12V190B engine, we made modification of the crank train, lubrication system, monitoring system of series 2000 in point view of safety, reliability and maintenance. The variant speed of the gearbox fulfills the requirements of the ships for transportation and engineering ships with higher speeds and loads. It is convenient for connecting the mudding pump, hydraulic pump and water pump. Furthermore, it also realize the pneumatic and electrical starters, remote operation and two engines combined. 
This series of engine have been wildly used for the main propulsion of fishing management vessels, high speed passenger liners and seafood transporting ship. Additionally, they also provide power take-off for the tugboats and dredgers in Changjiang River, ports and coastal area. They are also sold to North Africa for trawlboats and fishing boats. In naval market, the main applications are for destroyers, frigates, gunboat, electrical detection and measuring boats as the main power of main propulsion and auxiliary engines. 

As users required, some models of engines could be modified to be operated with heavy diesel.
Owning to good economy and reliability, this series engines, with high power, low consumption and easy maintenance, cater for the customers very much. Single engine, fire control pumping sets with single bearing, gearbox sets, marine gensets are well sold to a lot of countries and areas, such as TaiWan, Malaysia, Indonesia, Vietnam, Tunisia, Morocco, Mexico, Ecuador, Peru, Venezuvena, Brasil, Nigeria, Ghana, Tanzania, India, Thailand, etc
