🔍 Key Concepts

• Cable penetrations in watertight bulkheads and how watertight integrity is maintained • Purpose of grounding/bonding for electrical systems on ships • Typical methods of securing cables vs. methods that would damage or compromise them

💭 Think About

• Think about how a cable can pass through a watertight bulkhead without allowing water to leak. What kind of fitting or arrangement is normally used? • Consider whether grounding cable coverings is generally a safety feature or a hazard on ships. • Ask yourself which listed methods would realistically be used in ship construction and maintenance, and which sound like they could damage the cable or be impractical.

✅ Before You Answer

• Verify which option maintains watertight integrity while allowing the cable to pass through the bulkhead safely. • Check whether shipboard electrical safety practice calls for proper grounding of metal parts or for avoiding grounding altogether. • Eliminate any choices that would obviously damage insulation or prevent maintenance of cables (e.g., permanent adhesion or welding directly on the cable).
