Tokyo Keiki standby compass maintenance for oil tankers

⏱️ 5 min read

Tokyo Keiki Standby Compass Maintenance for Oil Tankers is a vital service to ensure continuous navigational reliability when electronic systems fail. The standby compass, particularly models by Tokyo Keiki, acts as the last line of defense in marine navigation. SEANAV specializes in the inspection, testing, and maintenance of these critical instruments, ensuring oil tankers remain compliant and operational under SOLAS regulations.

Why Standby Compass Maintenance Matters for Oil Tankers

Oil tankers often traverse long, complex routes and must rely on accurate heading data. In cases where the main gyrocompass fails, the Tokyo Keiki magnetic standby compass ensures safe navigation. Regular maintenance helps eliminate deviation errors, correct damping issues, and maintain proper fluid levels—all essential for safe voyage planning and execution.

What We Do at SEANAV

  • Visual inspection of compass housing and fluid
  • Correction of magnetic deviation and card alignment
  • Checking compass gimbals, pivot, and damping fluid
  • Lubber line realignment and dial recalibration
  • Testing for heading stability during vessel motion
