Tropical Storm and Heavy Weather Navigation

This course provides the knowledge, skills, and behaviors required to safely navigate a vessel in tropical storms and heavy weather conditions. It also aims to minimize damage and cargo loss or claims resulting from cargo loss overboard in severe weather conditions.

Training Outcome/s:

• Explain tropical storm formation
• Identify and plot the tropical storms
• Avoid the dangerous semicircle of the tropical storm
• Create an anti-collision plot to avoid tropical storms
• Explain and recognize the ship’s behavior in the seaway
• Explain the influence of rolling in severe weather
• Determine the parameters needed to assess if the ship is being successively attacked by high sea
• Demonstrate the preparation of the diagram to avoid successive high-wave attacks
• Identify the required control measures to avoid synchronous rolling
• Identify the required control measures to avoid parametric rolling
• Use the diagram to get the period encountered
• Use the Bretschneider diagram to forecast waves, predict the significant wave height, and fetch length/duration
• Demonstrate an accurate meteorological voyage planning necessary to avoid areas with heavy weather and implement the required control measures
