7.9.1 Engine exhausts

The onboard engine exhaust system is equipped with a double smoke treatment system:

  1. The first stage consists of insulated, dry-steel marine mufflers suitable for reducing engine noise emissions;
  2. The second stage consists of a composite muffler, in which the exhaust gases are cooled and silenced by means of sea water injection.


WARNING

When starting the engines, check that water comes out of the exhausts; this means that the engines cooling system works correctly and that the exhaust is cooled. Accelerate if no water comes out.
If the problem continues, contact the Service Department.

MAINTENANCE

At least once every three months carry out the tightening of the discharge raiser bolts.

CAUTION

A strong smell and a light smoke from exhaust insulation are normal dur-ing the first period of use.
