Remarks:
VIQ requires Compass to be adjusted every 2 years, or whenever deviation is excessive.
Magnetic and Gyro compass errors should be checked and recorded each watch, where possible, using either azimuth or transit bearings. Where errors unobtainable, due to weather, traffic density, or otherwise, the reason should be recorded in the deck log book.
It is clearly given in VIQ that if errors cannot be taken this need not be mentioned in the error book. However, company procedures must be followed.
The inspector cannot confirm that the deviation is excessive when the vessel is alongside just by looking at the difference between Gyro and Magnetic compass because of shore structures which can affect the reading. This is clearly mentioned VIQ 4.9 (last para).
