Efficient Application of Super Moon Pool Special Engineering Barge in Integral Salvage and Relocation Project of Ancient Ship

doi:10.16183/j.cnki.jsjtu.2023.S1.19

Abstract

Abstract:

This paper introduces the design concept of the innovative barge “Endeavor” for the super-large moon pool project and its high-efficiency application in the integral salvage and migration project of “Yangtze River Estuary II” ancient ship. It also introduces the calculation of the lifting force of the ancient ship compared with the actual lifting weight. The successful application of barge “Endeavor” in the integral salvage and relocation project of “Yangtze River Estuary II” ancient ship provides technical reference for future salvage of ancient ships.

Key words: super moon pool, barge “Endeavor”, integral salvage, synchronous lifting, Yangtze River Estuary II
