2. Diesel Engines
2.1 Trend in the World
According to the Annual Analysis by the magazine The Motor Ship, the shipbuilding output in the world in 1996 is 986 ships at 38,462,872 DWT, and increased by 102 (11.5%) in number at 3,958,080 DWT (11.5%).
The total deadweight in Japan occupies 43.2%, and 80.8% of the world production is shared by the Far East 4 countries including Japan and Korea ranking the second in the world (30.1%), China ranking the third (4.4%), and Taiwan ranking the fifth (3.1%). The building output of Denmark, who ranked the third in the previous year was decreased to 1/3, and retracted to the ninth rank. (Table 2.1-1).
Though the increase in new shipbuilding in the world is welcome, cyder tonnage is not being scrapped, expressing the anxiety for the excessive bottoms and the drop of freightage.
Similarly, according to the statistics of the magazine The Motor Ship, the results of the total manufacture of diesel engines in the world in 1996 by the manufacturer are indicated in Tables 2.1-2〜4, and 1080 engines were mounted on 974 ships. The total production in the world is 10,216,595 kW, and increased by 14% compared with that of the previous year. In the low speed diesel engines, MAN B&W engines occupies 64% of the whole engines, running ahead of the second-ranked Sulzer engines occupying 27.5%. Even in the medium-speed engines, MAN B&W engines ranked the fourth in the previous year, jumped to the top with its share of 19.2%, followed by Wartsila, Pielstick, MaK, and Sulzer whose share is 14.7〜12.2% respectively.
Reorganization of the diesel engine manufacturing industry including merging of Caterpillar with MaK, and purchase of New Sulzer Diesel by Wartsila was marked.
2.2 Domestic Trend by Statistics of Nippon Kaiji Kyokai
According to the statistics by Nippon Kaiji Kyokai, 385 newly-built ships were registered with NK class in 1997, showing the increase by about 5% compared with 365 ships in 1996. (Table 2.2-1) Among the total newly-built ships, 382 ships are equipped with diesel engines, and the total output is 2.44 x 106 kW (3.32 x 106 PS), showing greater increase by 17% compared with 2.08 x 106 kW (2.83 x 106 PS) in 1996. This is attributable to the fact that the engines from 7,353 KW (10,000PS) to 14,706 KW (20,000PS) class in output per 2-stoke engine was greatly increased in number.
