MAN B&W Diesel A/S

Description of the ME Engine.

Please note that engines built by our licensees are in accordance with MAN B&W drawings and standards

but, in certain cases, some local standards may be applied; however, all spare parts are interchangeable with MAN B&W designed parts. Some components may differ from MAN B&W's design because of local production facilities or the application of local standard components. In the following, reference is made to the item numbers specified in the ‘Extent of Delivery’ (EoD) forms, both for the ‘Basic’ delivery extent and for some ‘Options’.

Bedplate and Main Bearing

The bedplate is made with the thrust bearing in the aft end of the engine. The bedplate consists of high, welded, longitudinal girders and welded cross girders with cast steel bearing supports. For fitting to the engine seating in the ship, long, elastic holding-down bolts, and hydraulic tightening tools.

The bedplate is made without taper if mounted on epoxy chocks or with taper 1:100, if mounted on

cast iron chocks. The oil pan, which is made of steel plate and is welded to the bedplate, collects the return oil from the forced lubricating and cooling oil system. The oil outlets from the oil pan are normally vertical and

are provided with gratings. Horizontal outlets at both ends can be arranged for some cylinder numbers, however this must be confirmed by the engine builder. The main bearings consist of thin walled steel shells

lined with bearing metal. The main bearing bottom shell can be rotated out and in by means of special tools in combination with hydraulic tools for lifting the crankshaft. The shells are kept in position by a bearing cap.
