1] DU-Sulzer RTA58T
Engine
Following the DU-Sulzer RTA48T-type engine completed in 1996, the DU-Sulzer RTA58T-type engine which had been developed as the main engine for medium to small bulk carriers and tankers was completed in February, 1997, and after the confirmatory tests for about 1 month on the reliability and various performances were carried out, the engine was delivered to the customer. The first model is the 7RTA58T 19,040 PS x 103 rpm, for the main engine for the AFRAMAX tanker built by NKK. The development targets of the RTA58T type engine are as follows based on the experiences with the conventional RTA series engines, and the particulars of the engine as the main engine most suitable for the market requests were determined.
1) Output and engine speed optimum for the ship planning
2) Realization of low fuel consumption and improvement of the propeller efficiency by the super-long stroke
3) Excellent reliability
4) Reduction in maintenance works
5) Simplification of installation and outfitting
The principal particulars and the section of the DU-Sulzer RTA58T type engine are indicated in Table 2.4.5-1 and Fig. 2.4.5-I respectively.
