Top bracing installed to reduce transverse vibration of main engine.
"bad" operation creates cracks of bracing connecting with main engine and hull,
excess transverse main engine vibration and cracks to main engine base chock fasts.
Main engine top bracing has to inspect and adjust:
1.-During official sea trials to partition shipyard responsibilities and avoid guarantee claims later on
2.-Unexpected change of hull vibration level
3.-Turbocharger(s) start to vibrate intensely
4.-After shafting and main engine alignment
