  8. 8. FLNG Docking and Mooring Systems General Observations  Onshore/near shore docking and mooring FLNG / FSRU applications.  Majority of current projects are floating onshore regasification.  Floating regasification applications more complex from a mooring system integration standpoint.  Many of the mooring scenarios involve a compound mooring arrangement.  The docking and mooring system elements tend to be considered in isolation.  LNGC/FSRU – Shipbuilder focusing on primarily FSRU Ship-to-Ship mooring system hardware.  FSRU/LNG Jetty – Civil EPC focusing on jetty construction.  The total mooring system must be considered in its entirety.  The “system” includes mechanical elements, instrumentation and control & monitoring. 8 29-11-2013 TRELLEBORG GROUP
  9. 9. Mooring A Primer  Structural Element between entities  Jetty to Vessel  Vessel to Vessel  As it is dynamic it requires observation and adjustment  Because there is a designed state  And an operational state  Aim is to achieve the designed state to limit vessel excursion. 9 29-11-2013 TRELLEBORG GROUP
  10. 10. Docking A Primer  Jetty / Berths, designed berthing speeds  Based on structure loading  Fender criteria (PIANC)  Hull Pressures   Ship to Ship berthing speeds have set limits Once moored during product transfer, predefined vessel excursion limits apply   10 Docking systems monitor all those states Implements a feedback loop for control of the process 29-11-2013 TRELLEBORG GROUP
  11. 11. Environmental & MetOcean A Primer  Designs have set MetOcean and Environmental States  Prior to berthing  Sea States  Wave, Current, Water Level , Tide Trend  Weather Conditions  Wind , Barometric Pressure, Temperature , Humidty  Lightning / Storm  During berthing  Sea States  Wave, Current, Water Level , Tide Trend  Weather Conditions  Wind , Barometric Pressure, Temperature , Humidty  Lightning / Storm  Purpose is to ensure Operations can be safely carried out within designed conditions and limits. 11 29-11-2013 TRELLEBORG GROUP
  12. 12. System Integration A Primer  All Data - one system  Distribute relevant data to each party in the operations  Correlation of data for reporting and analysis  Logical control and monitoring   One System Provide a feedback loop for : Human Control of the process    12 Expert Vendor Fully considered system architecture One clearly defined maintenance and support path 29-11-2013 TRELLEBORG GROUP

  20. 20. Design Considerations Instrumentation, Control and Monitoring considerations  Who requires monitoring system data? – Plant operations/Process Oversight – FSRU and ashore – Terminal operations floating and ashore – LNGC deck officers  Where will the cargo operations be controlled from?  Safe execution of emergency release – assurance that only the desired vessel is released during an emergency.  Equipment choices for Hazardous Areas: Zone 1 Zone 2 Explosion proof (Ex d) or Increased Safety (Ex e)?  Ingress Protection (IP Rating) 20 29-11-2013 TRELLEBORG GROUP
  21. 21. Compliance Requirements  Compliance to Class DNV , ABS , BV , RINA  IMO MSC /1175 (Guidance on Ship Towing & Mooring).  ISO 28460:2010 Petroleum and natural gas industries — Installation and equipment for liquefied natural gas — Ship-to-shore interface and port operations.  OCIMF MOORING EQUIPMENT GUIDELINES (2009)  SIGTTO, LNG operations in port areas  SIGTTO, ESD arrangements and linked ship/shore systems for gas carriers 21 29-11-2013 TRELLEBORG GROUP
  22. 22. Mooring System Arrangements  Consider impact on system integration  Where will centralized control and monitoring be located? Golar KHANNUR West Java Höegh LNG 22 29-11-2013 Petrobras Guanabarra Golar Spirit Dubai LNG Golar Freeze TRELLEBORG GROUP

  25. 25. Spread Mooring Solutions  Load Monitoring to 250t  Releasable at Full SWL  MBL > 1200 t 25 29-11-2013 TRELLEBORG GROUP
  26. 26. Design Considerations Mechanical mooring system elements Quick Release Hawser Hooks  Coordination of QRH sizing (SWL) between Jetty and FSRU  OCIMF guidelines versus MCS – Operational based “recommendations” versus defined maximum structural limits  QRHs on the jetty may also be utilised by the transient LNGC  Semi Permanent nature of FSRU creates special challenges – mechanical equipment difficult to access for maintenance  The jetty mooring lines may be terminated by chain stoppers on the FSRU – typically the mooring winch brake is the limiting factor 26 29-11-2013 TRELLEBORG GROUP
  27. 27. Design Considerations Mechanical mooring system elements Ship-to-Ship FSRU/LNGC  Length of mooring line affects shock absorbing capabilities  Lines are potentially provided by transient LNGC  Pneumatic fenders and deployment system 27 29-11-2013 TRELLEBORG GROUP
  28. 28. Fender Deployment Systems Considerations for Floating LNG  Operator safety & risk minimization during operation.  High structural integrity, considering possible “damage state” integrity.  Lift capacity, considering dynamic factors.  Slack wire tensioning  HPU power & redundancy options.  Demanding open sea protection needs.  Deck footprint area minimization 28 29-11-2013 TRELLEBORG GROUP
