Q

Why is a chain bridle preferable to a wire rope towing bridle on a long ocean tow?

🔍 Key Concepts

• Catenary effect in towing gear and how weight affects shock absorption • Differences between chain and wire rope in terms of flexibility and abrasion • What characteristics are most important for a long ocean tow (sea state, surge, shock loads)

💭 Think About

• Think about what happens to the towing gear when the tow and tug move in heavy seas. Which material shape (chain vs wire) better absorbs sudden changes in distance? • Consider how each option (A, B, C) relates to real-world wear, maintenance, and performance in ocean conditions. Are all three statements equally true for chain bridles? • Ask yourself whether the main advantage on a long ocean tow is one specific characteristic, or a combination of several advantages.

✅ Before You Answer

• Verify how weight and sag (catenary) of chain affects shock loading compared to wire rope • Check which material is generally better against abrasion when lying on chocks, fairleads, or the bottom • Confirm whether maintenance requirements for chain vs wire rope are significantly different in practice for towing applications
