Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, specifically relating to a height adjustment device and method for a ship's compass. Background Technology

[0002] An gyrocompass is an electronic navigation instrument that provides true north as a reference point, used in ship navigation to determine course and the bearing of landmarks. The course compass, as a complementary instrument to the gyrocompass, is typically installed on either side of the bridge, with the compass dial generally between 1200-1400 mm high. Obviously, this height is unsuitable for taller crew members. To avoid later modifications, although shipyard technicians have communicated with the shipowner and confirmed the height of the course compass during the early stages of ship construction, it is inevitable that some ships nearing delivery will require modifications to the course compass height after the crew boards, resulting in significant modification work and economic losses for the shipyard.
