MARIN is pleased to announce the release of RollPeriod, a new mobile app that enables crew and maritime professionals to measure a ship’s roll and pitch periods directly on board. Available for both iOS and Android devices, the app turns any smartphone into a practical, accurate measurement tool.
Understanding a vessel’s roll period is essential for assessing the risk of synchronous or parametric roll. RollPeriod supports this by using the phone’s built‑in accelerometer, combined with FFT analysis, to determine roll and pitch periods in real time.
The development of RollPeriod aligns with one of the ambitions of the TopTier Joint Industry Project, which aims to reduce the risk of container loss at sea by improving operational awareness.
The app was developed by Diane Queau and Teiva Mettelet during their internship at MARIN. We thank them for their excellent work and valuable contribution.

Key features
- Accurate real‑time roll and pitch period detection
- CSV import and export** for further analysis and reporting
- Direct insight into the relation between roll period and stability (GM)
