In other words: "allows the nowadays state of the art technology a safe operation of large Diesel engines at all".

To approach this question, another aspect is coming up first: what is a "safe operation"? Should the answer be either following the sense of SOLAS (Safety of Life at Sea) or should we go further to include also the protection of material value?

Also the definition of "Safety of Life at Sea" is to be seen under two aspects :
direct protection of the human body against impact by an exploding engine, fire or mechanical destruction or on the other hand indirect by protection of the engine itself against damage. Even the loss of material value e.g. a dropped out, not reparable engine on the high seas could lead to the loss of the entire ship.

Safety measures however reach economical limits. But as long as the investments into safety measures are not exceeding a one percent level of the hole investment cost for the engine it should be considered.

Assuming the cost of a 5.000 kW Diesel engine of about 1,2 Mio. US$, 1% of this amount should be enough to protect this engine high grade against a heavy damage. A based assumption however must be the investors confidence into the efficiency of the security system.
If this Forum deepens the investors confidence due to a better knowledge about OMD, the Forum's goal is reached.
