Critical Running

When running undercritical, significant varying
torque at MCR conditions of about 100150% of
the mean torque is to be expected.

This torque (propeller torsional amplitude) induces
a significant varying propeller thrust which, under
adverse conditions, might excite annoying longi-
tudinal vibrations on engine/double bottom and/or
deck house.

The yard should be aware of this and ensure that
the complete aft body structure of the ship, in-
cluding the double bottom in the engine room, is
designed to be able to cope with the described
phenomena.

Overcritical running

The natural frequency of the onenode vibration
is so adjusted that resonance with the main criti-
cal order occurs about 3070% below the engine
speed at specified MCR. Such overcritical con-
ditions can be realised by choosing an elastic
shaft system, leading to a relatively low natural
frequency.

The characteristics of overcritical conditions are:

• Tuning wheel may be necessary on crankshaft

fore end

• Turning wheel with relatively high inertia

• Shafts with relatively small diameters, requiring

shafting material with a relatively high ultimate
tensile strength

• With barred speed range (EoD 4 07 015) of

about

±

10% with respect to the critical engine

speed.

Torsional vibrations in overcritical conditions may,
in special cases, have to be eliminated by the use
of a torsional vibration damper.

Overcritical layout is normally applied for engines
with more than four cylinders.

Please note:

We do not include any tuning wheel or torsional
vibration damper in the standard scope of supply,
as the proper countermeasure has to be found af-
ter torsional vibration calculations for the specific
plant, and after the decision has been taken if and
where a barred speed range might be acceptable.
