Common Rail At Sea: The Sulzer RT-flex Engine

SUMMARY

The paper gives a brief report on the experience with the first Sulzer RT-flex engine in the bulk carrier Gypsum Centennial. This is the world’s first large low-speed diesel engine in service with electronically-controlled common-rail fuel injection. The Sulzer RT-flex engine brings useful benefits in terms of reducing running costs, extendable times between overhauls, reduced exhaust emissions and ‘super dead-slow’ running. Particularly impressive during the sea trials were the completely smokeless operation at all ship speeds and steady running of the engine at speeds down to 12 rev/min. In service the engine has run well, up to our expectations, although with a few teething problems which are all covered in this paper.
