3] ZP-31CP type z-propeller
The ZP-31CP type Z-propeller of 1,544 kW(2,100 PS) in the rated input horsepower and having the controllable pitch propeller (CPP) function, was developed based on the 360｡?ull-turn, Z-type propulsion system of the fixed pitch propeller (FPP) with many experiences. Because it is the CPP, the power of the main engine can be distributed to the drive of the fire-extinguishing pumps, hydraulic pumps, generators, etc., in addition to the drive for the propulsion system, and the electric propulsion system is characterized in that the speed control of the drive motor is unnecessary. The main particulars and the photo of the general view of the ZP-31CP type propulsion system are indicated in Table 2.4.6-3 and Fig. 2.4.6-3 respectively.
(2) Annual results of manufacture
Table 2.4.6-4 indicates the total number of production of main engines, auxiliary engines, turbo chargers, elastic couplings, Z-type propulsion systems, and water-jet propulsion systems in 1997, and the total output of the main engines and auxiliary engines.
2.4.7 NKK Corporation
1) Annual results of manufacture
The NKK-SEMT-PIELSTIK engines for ship propulsion manufactured by NKK in 1997 include 6 PC2-6 type engines, 2 PC4-2 type engines, totaling 8 sets and 197,600 PS.
2.4.8 The Hanshin Diesel Works, Ltd.
(1) Development of New Model
Since the manufacture of Kawasaki MAN B&W 2-cycle engine was commissioned by Kawasaki Heavy Industries, Ltd. in 1986, this type of engines have been manufactured.
The 8L35MC engine of 7,040 PS was newly manufactured in the MARK6 rating advancing the line-up from the 4L35MC engine of 3,520 PS to the 8L35MC engine.
