Tugboat to help the ship by berthing operations, the main tool is the main drag cable, in our usual work process, how to properly use and conservation, is a major issue of the tug crew. We do these two tasks: First, to ensure safe production operations; the second is to create economic value. Because the driver is operating correctly, the cable is properly maintained, can extend the service life of the streamer, Shenhua drag 6 round by strengthening the front of the cable to protect the cable to prevent the cable wear too fast to extend the service life of the cable.
Let's talk about the use and protection of the streamer
1, when a new tow rope is used, it should be used after 1 year, the main drag cable for U-turn, because the main cable in the cable when the cable will be a certain wear, but do not cut off the parts , Thus causing the length of the streamer is insufficient, causing the drag force to change.
2, to always check the cable hole and the state chain is smooth, such as the cable hole glitch phenomenon, to smooth polished in time to prevent the cable cut cable caused by cable break phenomenon.
3, when the ship to help berth operations, the cable put away, the cable should be slowly force to prevent sudden force is too large, resulting in cable around the cable hole wear serious.
4, when the towing cable, the tugboat bow and the ship sometimes appear in the direction of the direction of the cable hole, drag rope with force, there will be bow bow phenomenon, at this time the driver in operation, can not accelerate, only Can slow down the force. Because the bow suddenly force, the bow swing too large, while the reaction force is too large, easy to cause serious damage to the cable or broken cable.
5, in order to make the front to enhance the use of cable extension time, in the pipa head 5-6 meters away from the distance of the production of protection, will strengthen the cable all wrapped in the inside without grinding, it is best to use the old reinforced cable to protect , Because the more wear-resistant, because the ship's cable pile and the cable hole between the distance of 3-5 meters, but there are 8-9 meters from the boat is a minority.
6, so that the protection of the use of cable benefits have three points: First, to prevent the main drag the cable outside the wear; Second, the site of the cable assembly, broken strength increases, not easy to break here; third is to ensure that the length of service, Resulting in economic benefits, every three years can save the cost of each boat to enhance the cable.
