无人货驳的坐底式打捞起重工程船改造设计

Reconstruction Design and Application of Bottom-supported Salvage CraneVessel from Unmanned Cargo Barge

为有效实施针对浅水礁区搁浅失事船舶的海难打捞作业,将1艘无人货驳改造为坐底式打捞起重工程船,基于合理的坐底稳性和强度评估,通过船体布置优化设计、船体结构加强及相关设备系统的配置,结合结构应力监测系统的设置,使得改造后的船舶能安全可靠地进行坐底打捞起重作业。

In order to effectively implement the salvage work of the wrecked ship at reef area in shallow water,an unmanned cargo barge was transformed into a bottom-supported salvage crane vessel.Based on the reasonable bottom-supported stability and strength evaluation,and through the optimization design of general arrangement,strengthening of hull structure and the configuration of relevant equipment system,combined with the setting of structural stress monitoring system,the reconstructed ship can carry out the bottom-supported salvage and lifting operation safely and reliably.
