deep submergence vehicle crewmember Interview Questions and Answers

1. What are your primary responsibilities as a DSV crewmember?

   • Answer: My primary responsibilities would include assisting in the operation and maintenance of the submersible, monitoring vital systems, conducting scientific observations and data collection, maintaining situational awareness, and ensuring the safety of the crew and the vehicle during dives.

2. Describe your experience with underwater navigation systems.

   • Answer: I have experience using inertial navigation systems, Doppler velocity logs, and sonar systems for underwater navigation. I understand the principles behind these systems and their limitations, and I am proficient in interpreting the data they provide to maintain accurate positioning and heading.

3. How familiar are you with different types of submersibles (e.g., ROVs, AUVs, HOVs)?

   • Answer: I am familiar with the differences between remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and human-occupied vehicles (HOVs). I understand their respective capabilities, limitations, and operational procedures. I have [mention specific experience if any, e.g., "hands-on experience operating an ROV during a research project"].

4. Explain your understanding of decompression procedures.

   • Answer: I understand the importance of decompression to prevent decompression sickness ("the bends"). This involves carefully controlled ascents to allow dissolved gases in the body to be released gradually. I am familiar with decompression tables and algorithms, and I know the procedures for managing decompression emergencies.

5. How would you handle a pressure leak in the submersible?

   • Answer: I would immediately report the leak to the pilot and follow established emergency procedures. This would include assessing the severity of the leak, attempting to locate and contain the source (if possible and safe), preparing for emergency ascent, and communicating with the support vessel.

6. Describe your experience with underwater communication systems.

   • Answer: I have experience using acoustic communication systems for underwater communication, understanding their limitations in terms of bandwidth and range. I am familiar with procedures for maintaining clear and concise communication with the support vessel.

7. How would you handle a power failure in the submersible?

   • Answer: I would immediately initiate emergency power procedures, which might involve switching to backup power systems. I would then assess the situation, conserve remaining power, and prepare for an emergency ascent using the appropriate safety protocols.

8. What safety procedures are you familiar with regarding DSV operations?

   • Answer: I am familiar with pre-dive checks, emergency procedures, communication protocols, life support systems maintenance, and the use of emergency equipment. I understand the importance of adhering to strict safety guidelines throughout all phases of a DSV operation.

9. How do you maintain situational awareness during a dive?

   • Answer: Maintaining situational awareness requires constant monitoring of the submersible’s systems, navigation data, communication with the support vessel, and visual observation of the surrounding environment. I would also actively participate in communication with the pilot and other crew members.
