A Review on the Mega Offshore Platform Topside Lifting and Jacking Technology

How to complete topside lifting safely and efficiently is the key issue of mega offshore platform construction and mating. This paper focuses on the topside lifting and jacking technology of mega offshore platform mating, and investigates the recent domestic and overseas cases of mega offshore platform topside lifting and jacking. It conducts research on lifting and jacking technical characteristics, which is analyzed in terms of equipment, capability and process, which sums up the technological superiority of lifting and jacking by comparing the weight, height, security and economic factors and proposes a safety factor of lifting process. The paper proposed a reliable theoretical basis and reference for the mega offshore platforms mating.
