Multi-point anchoring pilling vessel and flatbed barge are usually adopted for piling work on water in domestic port and waterway projects.Before driving piles,the anchoring positions of each cable of the two vessels should be planned to avoid collisions between cables and surrounding structures,as well as scratches between cables.It is also necessary to ensure that each cable has sufficient length to ensure sufficient anchoring force.The anchoring conditions of an offshore oil terminal in West Africa are poor.A flatbed barge with hydraulic support studs (hereinafter referred to as the stud barge) is used instead of a conventional flatbed barge,becoming a new form of “piles carrier”.This article introduces the analysis method for the stability of the stud barge based on its application in this project,using a coupling method of finite element analysis and static mooring analysis to verify of the stud barge structure.The stud barge is anchored with studs,which is convenient to operate,especially suitable for shallow water and weak topsoil.This paper can be used as a reference for relevant industries when selecting offshore construction ships.
