海外石化码头项目装卸设施多层布置方案

Multilayer arrangement of operation facilities for overseas petrochemical jetty projects

针对国外石化码头平台相对于国内码头占地面积较大、设施拥挤严重的问题,提出一种新型装卸工艺设施布置方案,即码头结构采用双层设计,上层为日常操作平台,下层为靠泊系缆平台。在此基础上,装卸工艺设施分3层布置,其中需要日常操作的工艺设施布置在上层平台,辅助管道设施及电仪桥架悬挂在首层平台下,残液罐及废水收集池布置在下层平台。以东南亚某化工码头项目为例,介绍该布置方案的运用,并采用BIM技术创建码头装船工艺设施模型,进行装卸臂、登船梯的兼容性分析及相互间操作干涉分析,以提高码头操作可靠性及安全性。设计方案可显著优化装船平台布置,平台占用率降低40%,为运营操作、检修及改扩建提升了空间。同时,BIM技术用于船岸兼容性分析可避免装卸操作潜在的风险。

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.
