深水海底管道铺设安全辅助系统

此次研发的铺管安全辅助系统是一套自动化、简易化、旨在提高安装经济性和安全性的实时运行安全辅助系统,通过实时数据采集及处理,达到对安装期海管强度进行实时监测目的。系统组成包括设备系统和监测软件两部分。设备为系统提供辅助决策数据源;监测软件采用C++语言编写,用于数据接收、解析,并通过OrcaFlex API调用商业有限元软件OrcaFlex为分析内核进行实时分析计算,以可视化界面输出管道应力、应变、触地点等信息,给予船上作业人员安全指导,及时作出决策。

A vessel motion based pipeline safety installation assist system

Ocean engineering companies focus more attention on technology research and development for decreasing cost and increasing benefit to match lower oil prices. Offshore operation become a key research item as it costs 30-50% of the total package. Subsea pipeline installation has characteristics of "hidden", and its design is often based on a lot of conservative assumptions. The pipeline installation monitor is a set of automatic and easy operation safety assistant system to improve economy and safety by monitoring subsea pipeline strength during installation through the real-time data acquisition and processing. The system is composed of devices and monitoring software. The devices provide real time analysis data. Monitoring software is developed by c++ language, and used for data receiving, parsing and real time analyzing through calling commercial finite element software OrcaFlex by OrcaFlex API, thus finally visually outputting pipeline information such as stress, strain, TDP, etc., giving the ship operation personnel safety instruction, and making decisions in time.
