Installation Instructions
D.5 Watercooled Exhaust System
By injecting the outlet seawater into the exhaust manifold, the exhaust gases are cooled and the
noise emissions from the exhaust system are reduced.
D.5.1
Installation of the standard exhaust system
The generator exhaust system must remain completely independent and separate from the
exhaust system of any other unit(s) on board. The exhaust hose has an inner diameter of 30mm.
The water lock must be installed at the lowest point of the exhaust system. An optional noise
insulated water lock can also be installed. The exhaust hose descends from the capsule to the
water lock. Then the hose rises via the "goose neck" to the silencer (see drawing). The goose
neck must be vertical and sit preferably along the ship's keel centre line. The exhaust system
must be installed so that the back pressure inside the exhaust does not exceed 0.4 bar (6 psi)
and total length does not exceed 6m (20 ft.).
Exhaust diameter see Table F.3, “Technical Data Generator,” on page VI.
