[0002] At present, there are two types of offshore oil spill collection: surface collection and underwater collection. Surface collection is the main method, using oil spill cleaning ships, oil booms, oil absorbent mats, oil skimmers, etc. to recover oil spills. The main advantage of above-surface collection is that the technology is mature and the operating facilities are complete. The disadvantage is that the oil spill spreads on the sea surface and pollutes a large area. The advantage of underwater oil spill collection is that it basically collects from the source and has little pollution. The disadvantage is that the operation is difficult.
