According to NAVSEA Crane regulations, how many broken wires in one lay necessitate the replacement of the rope?

The correct answer is based on the specific criteria outlined in NAVSEA Crane regulations concerning the maintenance of wire rope. According to these regulations, if there are six or more broken wires within a single lay of the rope, it indicates a significant loss of integrity and strength in that section of the wire rope. This standard helps ensure safety during operations and prevents potential failures that could lead to accidents.

The regulation sets a threshold that, when met or exceeded, warrants the immediate replacement of the rope. It's important to regularly inspect wire rope for signs of wear, including broken wires, as part of routine maintenance to ensure operational safety. This guideline serves as an industry standard to maintain both compliance and safety in crane operations.
