🔍 Key Concepts

• Responsibilities of a towing vessel toward an unmanned barge • Basic safety requirements for tank barges (pollution, leaks, unauthorized access) • What actions are continuous duties versus special/rare procedures

💭 Think About

• Think about which option reflects an ongoing safety responsibility whenever you tow an unmanned tank barge, not just in special circumstances. • Ask yourself: which choice best prevents pollution, cargo loss, or tampering with the barge? • Consider which options sound like unusual actions that would only be taken in specific situations (e.g., during loading, inspection, or if there is a known problem).

✅ Before You Answer

• Eliminate any option that sounds unsafe or clearly contrary to good seamanship for a tank barge. • Ask whether a red flag is a standard, always‑required signal for this situation under current regulations. • Check which action you would logically need to maintain safety, security, and watertight integrity of an unmanned barge under tow.
