Emergency Contact

Understanding a ship's roll period is vital for assessing the risk of synchronous or parametric rolling, both of which can develop rapidly and lead to dangerous angles of heel, particularly in heavy weather or when carrying bulk or container cargo. The RollPeriod app turns your smartphone into an onboard measurement tool, using its built-in accelerometer and FFT analysis to deliver:

  • Accurate, real-time roll and pitch period detection
  • Easy CSV data import and export for deeper analysis — useful for logging readings and sharing with shore-based teams
  • Clear insight into how roll period relates to vessel stability (GM), supporting informed decisions on course and speed adjustments, ballast management and cargo distribution

Traditionally, accurately measuring roll period has required specialist equipment or complex calculations. RollPeriod makes this accessible to any vessel with a smartphone, putting a practical stability assessment tool directly in the hands of Masters and officers.

A compact, powerful aid for safer and smarter ship operations. The app can be downloaded on the App Store and Google Play.
