MARITIME ASIA activity, though, it was significant that Japanese completions of 2.131 million-gt and 1.444 million-com- pensated gross tons (cgt), during the third-quarter of the calendar year, remained in excess of South

Korea's deliveries.

Japan's work tally, accounting for 31 percent and 27 percent of the world total by gt and cgt respec- tively, is at its highest level in years, 50 percent more than it was in 1985 and three times that of the slump years of 1987-88.

Nonetheless, South Korean yards have trebled their workload over the same period, and their current two-year contract backlog repre- sents a substantial platform from which to launch a restructure of the industry. Figures issued by the

Japan Ship Exporters' Association (JSEA) showed that the export- designated contract intake in the 1997 calendar year, including ton- nage built for foreign affiliates of

Japanese companies, had reached

In line with the positive trends in demand, and out of consideration of recent years' generation of new capacity in South Korea, govern- ment controls on Japanese capaci- ty have been relaxed to some degree. A number of yards have been permitted to increase the extent of simultaneous construc- tion of ships up to a certain size, thereby providing builders with

New Japanese Engine Designs

Following on from the development in 1996-97 of the UEC43LSII engine,

Mitsubishi Heavy Industries is to add a smaller long-stroke design to its portfo- lio, in the shape of the UEC37LSII.

As Japan's only designer of large two-stroke diesels, and the single com- petitor in the field to the European- based market leaders MAN B&W and

Wartsila NSD Corporation,

Mitsubishi's diesel engine division has sought to increase the number of options available in its range of machinery up to 63,600-bhp, while pursuing an active product moderniza- tion program. The 430-mm-bore

UEC43LSII, covering a power band from 5,720 to 11,440-bhp, is posi- tioned as a replacement for the

UEC45LA type, while the nascent, 370- mm-bore UEC37LSII engine provides for powering configurations in the 5,250 to 8,400-bhp sector at a run- ning speed of 186-rpm, compared with the 160-rpm of the 43-type.

The prospective addition to the series has the same stroke-to-bore ratio of 3.49 as the UEC43LSII, a similar brake mean effective pressure (bmep), and a specific fuel consumption rating of 129-g/bhp-h, marginally above that of the 43 engine's 127-g/bhp-h.

A simplified and compact form of construction has been adopted, as reflected in the cast monoblock compo- sition of the camshaft box and engine frame, on the one hand, and the cylin- der jackets and scavenging trunk, on the other. The Japanese company has also unveiled a 520-mm bore diesel aimed principally at the market for

Panamax bulkers and smaller vessels.

The UEC52LSE has been designed to produce 2,320-bhp per cylinder at a crankshaft speed of 127-rpm, and is claimed to be one of the most fuel-con- servant in its class, requiring just 123- g/bhp-h. With its comparatively high power rating, the new type offers the same output as competing designs but with the advantage of one cylinder less.
