Overview

Preliminary assessment reveals that lateral accelerations relate more closely to task interruptions in fishing vessels, suggesting need for tailored indices.

Key Points

  • This research aims to assess how vessel motions affect operability and crew welfare in fishing vessels.
  • Characterized vessel dynamics using inertial measurement unit (IMU) on two Catalan trawlers.
  • Identified steady-navigation segments and analyzed them using Motion Sickness Incidence (MSI) and Motion Induced Interruption Index (MII).
  • Evaluated vertical and lateral accelerations to understand their impact on crew stability and task interruptions.
  • Vertical acceleration and MSI do not effectively indicate operability in fishing vessels.
  • Lateral accelerations (MII) show a strong correlation with task interruptions and crew stability during low-speed operations.
