  12. System Components • FMC Chicksan loading arms • Cryogenic loading hoses - Coflexip aerial hose & floating hose - OCL system cryogenic hoses • Amplitude LNG Loading System (ALLS) • Subsea cryogenic pipelines - Jacket insulated pipelines - Vacuum Insulated Pipelines

  13. Subsea Cryogenic Pipelines • ITP InTerPipe subsea cryogenic pipelines - Nickel alloy inner pipe, carbon steel outer pipes - Eliminate the need for a jetty - Not limited by length, diameter or water depth • Chart Industries vacuum insulated pipelines - Connect pipe section with bellow arrangements • - Used at Trinidad LNG plant as a 4” cool down line • - Used at Everett LNG receiving terminal

  14. System Evaluations Criteria • Technical status and qualification • System design and performance • Operability and maintainability • Safety and environmental • Cost and schedule • Shipping and marketing Subjective weighting of each criterion above is project specific

  15. Technical Status / Qualification • Level of development • Technical maturity level • Quality and depth of program • Gap identification and closure • Participation by certifying agency • Success confidential level

  16. Rating and Scoring

  17. Common Concerns • Lack of a common connector technology - Bow loading system - Amidships loading system • Flexibility for terminal and ship - To send our LNG carriers to any terminals - To accept any LNG carriers at our terminals

  18. Conclusions • Many innovative offshore LNG transfer systems are available and reviewed • Criteria for evaluation are safety, environmental, technical, commercial and political drivers • Common connectors and interfaces are important • Need to maximize the utilization of vessels and offshore LNG terminals • This paper offers a methodology for evaluating various LNG transfer technologies for successful deployment of offshore LNG
