Lilley & Gillie employs two very experienced and fully qualified D.O.T. certified compass adjusters, who are available 24 hours per day to carry out onboard adjustment and service.

Annex 13 of the MCA publication - Safety of Navigation - Implementing SOLAS Chapter V which superseded MGN 57 states that each magnetic compass required to be carried by the regulations shall be properly adjusted and its table or curve of residual deviations available at all times. Magnetic compasses should be adjusted when:

• they are first installed

• they become unreliable

• the ship undergoes structural repairs or alterations that could affect its permanent and induced magnetism

• electrical or magnetic equipment close to the compass is added, removed or altered; or,

• a period of two years has elapsed since the last adjustment and a record of compass deviations has not been maintained, or the recorded deviations are excessive or when the compass shows physical defects.
