What method is recommended to prevent pinching of the cargo hose between the vessel and the dock?

Adjusting the hose supports is the recommended method to prevent pinching of the cargo hose between the vessel and the dock because proper support ensures that the hose maintains an appropriate bend radius and does not experience excessive stress at any point along its length. When hose supports are strategically positioned, they help to distribute the weight of the hose evenly and prevent it from sagging or kinking, which can lead to pinching. By avoiding sharp bends and unsupported areas, the risk of damage to the hose and potential leaks is significantly reduced, thereby enhancing safety during cargo transfer operations.

In the context of other methods presented, laying out an excess length of hose on deck could lead to tripping hazards or would not necessarily address the issue of pinching effectively. Tying off the topping lifts and runners to winch heads is more related to securing the cargo gear than it is to managing hose arrangements. Installing hose preventers can be beneficial but primarily focuses on securing hoses against movement rather than addressing the support and positioning directly. Hence, adjusting hose supports specifically targets the critical risk of pinching, which is crucial for safe cargo operations.
