Operating modes and restrictions
There are three operating modes:
• Control On
Fully operational. This can be selected when the release conditions are ful-
filled (see in the following).
• Estimate Only
The speed of each engine and the relative phase angle between them is indi-
cated and continuously updated, but not controlled. This can be selected
when the release conditions are fulfilled (see below).
• Off
All control parameters of Synchro-Phasing control are reduced and reset to
initial value (zero). This can be selected at any time.
Release conditions
The following conditions must be fulfilled to activate the Control On and Esti-
mate Only modes. These conditions are:
• Both engines are running in ahead direction in normal operational condi-
tion and unrestricted operation conditions (no protective actions of the en-
gine or major failures)
• Both engines are operated within the speed conditions of the Synchro-
Phasing system
• Heavy Sea Mode is not active on either engine
• No major failure of phase angle control system is active
• Both engines have the same speed set-point and have completed the load
up /down programs to reach this speed set-point
Deactivation of the Control On and Estimate Only modes will occur if required.
Synchro-Phasing is also overruled and reset if engine limitations are reached.
After deactivation, Off will be automatically active.
NOTE
Any phase angle value entered into the user interface must be previ-
ously approved by WinGD’s Dynamics experts, as incorrect settings
can lead to excessive vibrations.
