Aiming at the problems that overseas petrochemical jetty platform always covers a relative larger areas and facilities are highly congested comparing with domestic jetty platform,this paper proposes a new layout scheme of operation facilities,that is,the jetty is designed with two layers,top layer is designed for routine operation,while bottom layer is dedicated for mooring.Based on this,the operation facilities can be arranged by three layers,the facilities needing to be operated routinely are arranged on top of layer,and the ancillary piping and electrical cable tray are suspended from the bottom of top layer,while the drain pot and drainage water tank are laid onto the bottom layer.Taking a petrochemical project in Southeast Asia as an example,this paper introduces the application of the proposed scheme and creates digital project model using BIM technology.In addition,it conducts the compatibility analysis and interaction interference analysis between loading arms and gangway to improve the reliability and safety of dock operation.The proposed plan can significantly optimize layout of loading platform,and the occupancy of platform is decreased by 40%,providing space for operation,maintenance and expansion.Meanwhile,BIM technology used for ship-to-shore compatibility analysis can avoid potential operation risks.
