3 TRELLEBORG MARINE SYSTEMS INTRODUCTION Trelleborg Marine Systems provides safe berthing and mooring solutions for demanding marine environments History Harbour Marine Engineering was established in 1971 Focus on onshore and offshore mooring equipment since 1980 Acquired by Trelleborg in 2006 Technical capabilities Proven ability to integrate complex solutions 50% of LNG jetties worldwide World leader in the supply of quick release hooks Complete Design Control Mechanical, electrical, instrumentation and software in-house design, procurement, manufacturing, QA, project management and after sale service 3

4 Past and Current FSRU Projects Recent Projects : Excelerate Escobar Argentina Golar Freeze for Dubai LNG Golar Frost for Livorno LNG Golar KHANNUR West Java LNG Hoegh FSRU 2459 & 2450 Golar Winter for Bahia LNG Mooring System Elements STS Quick Release Hooks Load Monitoring Remote Release RTK GPS Berthing Aid Fenders and Deployment System 4

6 FSRU Docking and Mooring System General Observations This presentation is focused on onshore/near shore docking and mooring FSRU applications Majority of current projects are floating onshore regas We are finding that floating regas are more complex from a mooring system integration standpoint 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 entirety The system includes mechanical elements, instrumentation and control & monitoring 6

7 Potential for a fragmented system 7

8 Mooring System Integration Challenges Safe and coordinated emergency release is critical 8

9 COMPLIANCE REQUIREMENTS DNV FLNG TERMINAL GUIDANCE DNV OTG -02 DNV SHIP RULES PART 3 CHAPTER 3 (2012) 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 9 August 25, 2010

10 Mooring System Arrangements Effect System Integration Considerations Where will centralised control & monitoring be located? Golar KHANNUR West Java Petrobras Guanabarra Golar Spirit 10 Höegh LNG Dubai LNG Golar Freeze

11 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 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 11

12 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 release 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) 12

13 Design Considerations Overall control and monitoring elements MetOcean and Environmental Docking Aids Mooring System Load Monitoring Interface with Ship-to-Shore Link (SSL) Ship-to-Shore Link (SSL) What is the ESD philosophy across all vessels? SSL Hot Line and general comms are consistent across all vessels SSL will mooring line data be transferred via the link or will an independent system? The demand for data sharing is increasing... Equipment location? Optimization of cabling (Fibre Optic Link, Copper, Wireless) 13

15 Project Evolution Petrobras Bahia Regasification Terminal Experience from Petrobras s previously implemented Pecem & Guanabara Regasification Terminals Petrobras required a permanent monitoring system on the FSRU for monitoring the complete mooring system as well as process data. A separate Fibre Optic LAN was specified for communicating process data. The Ethernet based system with multiple protocols over the new LAN supporting data exchange and control of outer Jetty LNGC QRHs from the FSRU without compromising safety. Data can be viewed from any suitably equipped remote workstation on the network 15

16 Project Evolution Petrobras Bahia Regasification Terminal FSRU side Control the release of outer LNGC jetty hooks Data output for LNGC is via the standard SSL Marine Load Monitoring Repeater FSRU is able to view Mooring loads from LNGC and the total loads as viewed from the Jetty The system has a provision for a RTK GPS STS docking system FSRU has access to all Met Ocean data as measured from shore side systems FSRU controls remote release of all LNGC lines, terminating on both the FSRU & the Jetty 16

17 Acquisition of SeaTechnik Key focus on interoperability between FSRU, LNGC and the Jetty Our plan is a single link between vessels and berths that allows for safety and integrity of ESD functionality as specified in ISO 28460:2010 Digital capable SSL is a reality and being installed on new build LNGC The backbone is based on utilization of a traditionally spare fibre optic pair which allows high integrity remote release control and interoperability with Trelleborg shore side and FSRU systems This eliminates the need to design a separate interface (as describe for the Petrobras Bahia project) This supports worldwide compatibility of the LNGC and FSRU fleets FSRU s removed from service for operational or maintenance issues can be easily replaced The new digital backbone is able to pass process control data from the FSRU to shore using industry standard protocols and enhancing interoperability 17
