The invention belongs to the technical field of salvage engineering, and discloses a salvage method using a split salvage ship. The split type salvage ship comprises a water surface operation mother body and an underwater operation son body which are connected in a split mode, and a salvage structure is arranged on the underwater operation son body. The salvage method using the split type salvage ship comprises the following steps that S100, the split type salvage ship sails to a ship sinking point, and the underwater operation son body and the water surface operation mother body are separated and sink to the position above a salvaged object to hover; s200, the underwater operation sub-body is fixed to the seabed; s300, the object to be fished is sealed in the fishing structure; s400, the underwater operation sub-body is separated from the seabed and carries the salvaged object to return to the water surface operation main body; S500, the underwater operation sub-body and the water surface operation main body are combined; and S600, the split type salvage ship carries the salvaged object to return to the dock, and the salvage structure and the salvaged object are dismounted. In the whole salvage operation process, only the underwater operation sub-body needs to dive to the seabed, assistance of divers is not needed, the operation risk caused by personnel diving is avoided, and the limitation of salvage depth is broken through. And moreover, the split type salvage ship can independently sail on the sea surface and does not need to be supported by other ships, so that the investment of salvage equipment is greatly reduced. In addition, the salvaged object is sealed in the salvage structure, so that marine pollution such as oil leakage in the salvage process can be reduced, and the marine environment safety is protected.

    本发明属于救助打捞工程技术领域,公开了一种利用分体式打捞船的打捞方法。其中,分体式打捞船包括分体式连接的水面作业母体和水下作业子体,水下作业子体上设置有打捞结构。利用分体式打捞船的打捞方法包括以下步骤:S100、将分体式打捞船航行至沉船点,水下作业子体和水面作业母体分离并下沉至被打捞物上方悬停;S200、将水下作业子体固定在海底;S300、将被打捞物封闭在打捞结构中;S400、水下作业子体脱离海底并携带被打捞物返回水面作业母体:S500、水下作业子体和水面作业母体合体;S600、分体式打捞船携带被打捞物返回船坞,卸下打捞结构和被打捞物。在整个打捞作业过程中,只需使水下作业子体下潜至海底,无需潜水员辅助,避免了人员下潜所带来的作业风险,突破了打捞深度的限制。并且,该分体式打捞船能够独立在海面航行,无需其他船舶支持,大大减少了打捞装备的投入。另外,被打捞物被封闭在打捞结构中,能够减少打捞过程中的漏油等海洋污染,保护海洋环境安全。
