POWER turbochargers such as the ABB VTR 4P series, able to develop pressure ratios up to 5:1, can be expected to presage a general uprating of the later models of medium-speed en- gines. It has been tested exten- sively on Wartsila Vasa R32, Sulzer
ZA40S and Bergen BR-type engines and is already the standard fitting on the very new Stork-Wartsila SW38 model.
Reduced crew numbers imply less manpower available for mainte- nance, and engines are expected to run for very long periods without inspection and overhaul. The use of advanced materials has greatly ex- tended the life of wearing parts such as piston rings, and some remark- able experiences have been reported.
Marine-type crankpin bearings or split connecting rods for trunk-pis- ton engines, enabling a piston to be withdrawn for ring inspection with- out having to disturb a bearing which is running well, are now common- place. Engines are cleaner in ap- pearance, with accessible peripheral equipment and much less exposed small-bore pipe work to gather dirt.

The 5th ABB Turbocharger Bonus
A global network of confirmed quality. And that's official.
ABB Turbo Systems have achieved official ISO 9001 certification of all products and services produced and performed by the entire organization. Naturally, the turbo team is proud of these awards. But this accomplishment is far more an incen- tive to proceed in our drive for perfection of the • . • r . "1 advanced techniques and dedicated attitude for which we
IX ICC! Hive l(Jl LI lc have always stood. For at ABB Turbo Systems, we know that innovation, technological efficiency, cost-effectiveness and reliable support are all equally important ingredients of a convincing performance.
And your bonus? With the official ISO 9001 hallmark of quality, ABB turbocharg- ers no longer require individual commissioning formalities. And that's a relief for any operator. At ABB Turbo Systems, quality means an incessant striving for enhancement.
Recognition of
C11U1C the present is our incentive for the future: ISO9001.

The so-called "intelligent engine provided with instrumentation ft on-line or on-demand self-monito ing of performance and condition, likely to become an option taken u by progressive owners.
This can be linked to a planne maintenance system, so as to ind cate a need for inspection of an item earlier than scheduled, shoul this be shown up by the conditio trend monitor.
High-Speed Diesels
Mitsubishi Heavy Industries ha built the 40-knot hydrofoil catama ran Super Shuttle 400 at it
Shimonoseki yard for fast inter-is land commuter traffic. For this typ of application, a lightweight ver sion of its SR 160 x 170mm 1,651 rpm model was developed.
The 16-cylinder S16R-MTK-J engine has an output of 2,100 kV (2,850 bhp) at 2,000 rpm and, framec in light alloy, weighs only 14,735 lb (6.88 lb.-5.00 lb.). It is claimed to b< the first engine of Japanese desigr below 5.3 lb.
Four low-inertia Mitsubishi tur bochargers ensure rapid, smokeless response to demands for accelera- tion, usual in this type of craft. Fue] consumption is less than 7.66 oz, (5.65 lb.).
It has been designed for easy maintenance in the confined situa- tions in which it is likely to be in- stalled. Six- and 12-cylinder light- weight versions will follow later this year.
Another recently-introduced high-speed engine is the Paxman
VP185, an exceedingly compact de- sign developing 2,611 kW (3,500 bhp) at 1,950 rpm with the unusual fea- ture of two-stage pressure-charging by means of six low-cost turbocharg- ers.
Deutz MWM has increased the cylinder swept volume and made some other design changes to its well-known 234 series of lightweight engines. Ratings are increased by some 30 percent to cover from 480 to 1,360 kW (650 to 1,850 bhp) at 2,100 to 2,300 rpm from eight to 16 cylin- ders. These models are now desig- nated the 616 series.
Steam Turbines Only For Gas
Carriers
The last surviving application of the marine steam turbine engine is in propelling LNG-carriers, where it reigns supreme in spite of very determined research and develop- ment efforts and full-scale demon- strations by both crosshead and
