Magnetic Compass · Position & Heading
The RIVIERA BW2 is a magnetic compass. It is normally installed at the bridge or wheelhouse top away from avoidable magnetic interference. It is designed for independent ship heading indication without reliance on electrical power. The operating principle relies on alignment of the compass system with the Earth's magnetic field. Compared with neighbouring models, the relevant differences are bowl/card/mounting/repeater arrangement and vessel-specific compensation; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on fluid/card condition, mounting, deviation records, compensators and independent heading comparison. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect bowl, fluid, card freedom, lubber line, mounting and illumination. Review the deviation card and recent compass-error records and check for new magnetic influences around the compass. Compare with an independent heading reference and verify any repeater or periscope arrangement.
Carry approved illumination lamps or LEDs, fuses and minor mounting or cover hardware where applicable. Major compass repair, fluid replacement and compensation should be handled by qualified personnel using the correct equipment.
