Overview of MNTB NOS MSA 45 certification course. 

This course covers the competence to plan for and establish system variances and their causes in magnetic compass, electronic compass and gyro compass navigation systems in compliance with safety rules, regulations and organisational requirements. The effect on associated machinery and interfaced systems and any further problems to be investigated and identified. Logical fault-finding techniques are applied to identify and isolate deviations, the causes are determined and equipment is adjusted as and where necessary. A full description of the variance, its symptoms and causes are accurately recorded for future use.

Target Group.

This course applies to individuals at the management level with responsibility for navigation systems on vessels of any type and of any registered power.

Pre-requisite; Students CV of experience and/or qualifications to be submitted at the time of booking this course. 


Part A (1).

1. Properties of magnets. Meanings of terms.

2. Terrestrial magnetism – variation, dip, total force, horizontal force, vertical force, local attraction; effects on deviation.

3. Ships magnetism; effects of permanent and induced magnetism. Sub-permanent magnetism.

4. Compass design; general principles.

5. Siting and alignment of compasses with due regard to proximity of magnetic material, electrical devices and other disturbing influences.

Magnetic screening.

Meaning of lambda (λ), mu (µ), and a ships multiplier. How to find and use these quantities.

 Part A (2).

Compass compensations;

Methods of swinging ship.

Construction of a curve of deviations and its practical use in coefficients analysis.

Part A (3).

Asserting the true bearing of the sun or a star and thence the compass error and deviation.

Recognition of the principle bright stars.

Checking accuracy of instruments used in connection with compasses.

Part B.

1. Use of compass adjusting apparatus.

2. Different methods of taking bearings. Use of pelorus and azimuth ring.
