Next message: Otis ltd: "T&T: Bahamas crossing conditions"
In an offline discussion this week, it occurred to me that one aspect of
turbo operation leads to what I believe is INCREASED reliability. I don't think
we've discussed this. When turbo installations utilize a dry riser to power the
turbo via engine exhaust heat, the wet riser is eliminated.
On my DD 8V71TI's for example, the risers to the turbo are cast iron,not
water cooled, and wrapped in insulation blankets. Now the hot risers can be a
potential fire problem themselves, however the elimination water cooled risers
greatly reduces failure from a water leak entering a rear cylinder. That's a
fairly common failure point in older engine installations, such as 8V53 stainless
water cooled risers. Water in my installation is injected after the exhaust
hump. During an exhaust hose replacement, I looked inside to confirm the water
runs down and out the exhaust, not down and into the engine cylinders...
