Latest GV large-bore engine simplified for maintenance

Important new features have been added to Gotaverken's large-bore engine,

GV 850/1700 VGS-U. The levers controlling the exhaust valve movement are now fitted in a hinged bearing block which can be tilted out of the engine. This feature makes all the parts in this section easily accessible.

To reduce the time required for removing the cylinder heads, a regular routine in overhauling work, all cylinder nuts are now of the Gotaverken patented hydraulic- jack type. This means that all 12 nuts in a cylinder head can be tightened simulta- neously by oil pressure.

These two innovations are typical of the several improvements made for the purpose of simplifying maintenance work and increasing the reliability of this engine still further.

The first engine to incorporate these new features, a 9-cylinder unit developing 23,850 b.h.p., has been installed in an ore-bulk-oil carrier of 100,000 tons d.w. built at Gotaverken's Arendal yard. A series of over 20 ships of this type is on order at Gotaverken. Five have already been delivered. The remaining ships in the series will have the latest 9-cylinder large-bore engine as standard propelling machinery.
