Deviation

Term from Maritime Navigation industry explained for recruiters

Deviation in maritime navigation refers to the difference between true north and magnetic north that affects a ship's compass readings. It's like having a GPS that needs regular adjustments because of nearby metal objects on the ship. Navigation officers need to understand and calculate deviation to ensure their ship stays on the correct course. Think of it as making sure your compass is giving you accurate directions despite interference from the ship's metal structure, cargo, or equipment. This is a fundamental skill in maritime navigation, similar to how a pilot needs to understand their aircraft's instruments.

Example Interview Questions

Senior Level Questions

Q: How would you handle a situation where you notice significant changes in compass deviation?

Expected Answer: A senior navigation officer should explain the process of investigating the cause (like changes in cargo or equipment), conducting new deviation calculations, updating deviation cards, and ensuring all navigation officers are informed of the changes.

Q: Describe your experience in training junior officers about deviation calculations.

Expected Answer: Should demonstrate teaching ability and explain how they break down complex concepts into simple steps, use real-world examples, and ensure proper documentation practices.

Mid Level Questions

Q: How do you calculate and apply deviation corrections during voyage planning?

Expected Answer: Should explain the process of using deviation tables, applying corrections to courses, and maintaining accurate records of compass errors throughout the journey.

Q: What factors can affect compass deviation?

Expected Answer: Should mention ship's metal structure, cargo types, electrical equipment, and how these factors can change over time or with different loading conditions.

Junior Level Questions

Q: What is the difference between variation and deviation?

Expected Answer: Should explain that variation is caused by Earth's magnetic field and is location-dependent, while deviation is caused by the ship's magnetic field and is specific to each vessel.

Q: How do you use a deviation card?

Expected Answer: Should describe how to read and apply corrections from a deviation card when taking compass readings, and understand when these corrections need to be applied.
