The loading of submarine cables is usually carried out at the dock of the manufacturer. The loading equipment includes fixed cable hoops and electric rotary tables.

The submarine cables are wound layer by layer and circle by circle on the cable reel, usually in a clockwise direction from the outside in; hard PVC sheets may be used to separate the cable layers as needed, and the layer number, the number of turns, and the inner and outer cable lengths should be marked and recorded; the lead-in cables for each layer should be arranged in a staggered manner to maintain a flat layout.

When coiling, the cable head should be led to the monitoring room for uninterrupted monitoring of the loading process. After the loading is completed, the submarine cable performance test should be conducted, and the handover procedures should be completed.

During the storage and transportation of the cable, the submarine cables in the cable coils should be covered with straw bags or colored tarpaulin. When the temperature exceeds 40°C, water should be sprayed regularly to cool down. All welding and other work that uses open flames on the construction vessel should be carried out away from the cable coils and the cable should be monitored by a designated person.
