| 摘要： | It's important to reiterate that the standard 3-2-1 alongside towing make-up for a tug and barge that I described last month is based on the typical practice of the working deck lines being used are the same size and strength. But that doesn't always have to be the case. For instance, you could use a two-part headline that is substantially larger than the other lines and come out with the equivalent to a three-part line. Sometimes straps or donuts (fixed-length loops) are deployed for this purpose as headlines and spring/shoulder lines. When is it okay to deviate from the standard 3-2-1 make-up? When there is little or no risk of a negative outcome from doing so. Sliding a barge up or down a dock face or doing a short shift between berths in benign environmental conditions are good examples. But err on the side of caution. It's only easier with two parts as long as nothing goes wrong. |
