SOLAS Chapter V – safety of navigation – magnetic compass – deviation and adjustment

Regarding SOLAS Regulation V/19.2.1.1, the NSI requires for every standard magnetic compass on board (update of the Ships Decree 1965):

• a current table or curve of residual deviations, which must be available at all times in the ship’s wheelhouse, so that the ship’s course and bearings can be corrected to the correct position;
• the date of each adjustment and other details must be recorded in the compass log;

Also, with reference to Annex G of ISO standard 25862:2019, every standard magnetic compass on board must be (re)adjusted:

• upon initial installation;
• when the heading reading on the standard magnetic compass has become unreliable (for example, after an accident);
• after repairs or structural modifications to the ship that affect the permanent and/or induced magnetism of the standard magnetic compass;
• after the installation, modification, or removal of electrical or magnetic equipment near the standard magnetic compass; • when the recorded deviations exceed 5 degrees;
• when the standard magnetic compass exhibits physical defects;
• after dry-docking the ship; and
• when the ship’s master deems it necessary for navigational safety (normally at intervals of not more than two years).
