Tide Tables are essential tools in maritime navigation that provide predictions of water levels at different times and locations. They help maritime professionals plan safe vessel movements, particularly in ports and shallow waters. Think of them as a schedule book that tells you when the water will be high or low at specific locations. These can be printed documents or, more commonly now, digital applications. Similar tools include tide charts, tide prediction software, and nautical almanacs. Maritime professionals need to understand and use these tables to ensure safe navigation and efficient port operations.

Q: How would you integrate tide tables into port operation planning?
Expected Answer: A senior maritime professional should explain how they would use tide tables to create schedules for vessel movements, considering factors like vessel draft, channel depth, and safety margins. They should mention coordination with pilots, port authorities, and vessel operators.
Q: How do you handle situations where actual tide conditions differ from predictions?
Expected Answer: Should discuss backup plans, safety protocols, and decision-making processes when tide conditions don't match predictions, including communication with relevant parties and emergency procedures.
Q: What factors do you consider when using tide tables for voyage planning?
Expected Answer: Should explain consideration of vessel draft, under-keel clearance, loading conditions, and how tide heights affect passage planning through shallow areas.
Q: How do you verify the accuracy of tide table information?
Expected Answer: Should discuss cross-checking multiple sources, using real-time tide gauges, and considering local conditions that might affect tide predictions.
Q: Can you explain how to read basic tide table information?
Expected Answer: Should demonstrate understanding of basic tide table format, including how to find high and low tide times, tide heights, and how to interpret the data for a specific location.
Q: What safety margins do you apply when using tide tables?
Expected Answer: Should show understanding of basic safety concepts like minimum under-keel clearance and the importance of adding safety margins to tide predictions.
