They use an air start system that injects a huge volume of air into clyinder that has the piston starting on the down stroke. Same method is used to reverse the motor, but they inject air on the upstroke so that the piston is forced back down, thus reversing the rotation.
The noise in the engine room on these things is deafening and noise protection is a must. I visited the engine room on a cruse ship that had a smaller series than the RT 96. I believe it was two seven clyinder motors, Anyhow, conversation was impossible.
Some other interesting features of these motors, they use a ball instead of a wrist pin so that the piston rotates. Connecting rod is two piece and the upper portion runs up and down vertically while the lower rod swings with the crank throw. These motors run on heavy crude that has to be heated before it can be injected. I do believe that diesel fuel is used at start up though.
The engine block is all welded up from plates rather than being cast. Sulzer apparently was the first to use this construction method. The cranks are made up of indivual pins and counter weights. Assembled with interference fit.
If you every go on a cruise, check to see if an engine room tour is available. They won't usually volunteer these tours due to the enviroment of the engine room.
