It is more than two decades since the first MC engines entered service. By now more than 6000 MC and MC-C engines are in service, and a general description of all the service experience obtained would make little sense. This paper describes the behaviour of the latest generation of MC/MC-C engines, which largely means engines having entered service since 1997. In this period the introduction of very large container vessels has attracted a lot of attention in the marine market, and the service experience gained from the main engines of the MC/MC-C types installed in these vessels are described. Irrespective of the fact that these engines have been given a lot of attention, other sizes of MC/MCC engines have also been given careful attention, for instance the S-MC-C engines introduced in 1996. This paper describes the present status of service experience with regards to the combustion chamber, the cylinder condition, including wear rates, is thoroughly dealt with. Furthermore, the performance of bearings, exhaust valves, fuel oil injection gear and engine structure are described. Also, in the aforementioned period, the electronically controlled cylinder lube oil system, the Alpha Lubricator, has been introduced. The experience with this system is dealt with, both with regard to the cylinder liner wear rates achieved, in conjunction with the cylinder lube oil feed rates used, as well as the service experience with the Alpha Lubricator itself.
