  1. MFP – Installation using a Jack up Rig Dr. Sanjaya Pillai, Business Head, GLND India, Aswathy Ezhampakkel, Sr. Naval Architect, GLND Qatar

  2. History • October 2006: NDC started operations in Mumbai by opening a project office to execute 4WPP & BCPB2 projects • 1stApril 2008: Noble Denton India Pvt Ltd established • January 2009: ISO 9001 certification awarded to Noble Denton India PvtLtd • April 2009 GL acquired Noble Denton • April 2008-May 2012: NDI executed many warranty projects.

  3. GL Group Business Streams • GL NOBLE DENTON (OIL and GAS) • Advanced Engineering and Consulting • Marine Operations and Consulting • Technical Assurance • Design and Execution • GL MARINE (CLASS) • Classification Society • GL GARRAD HASSAN (RENEWABLES) • Renewables

  4. MFPs -Definition BACKGROUND 1. Production wells on the verge of depletion, Additional wells can be drilled in the near vicinity if some marginal fields are available near the existing facilities. • Existing no. of Production wells is not sufficient to take care of increased flow. Additional wells needed for tapping the resources. • Marginal fields exploitation, Minimum facilities for feasibility considering other factors like cost, grouping of fields etc. • Concept of Minimum Facilities Platforms

  5. MFP - Installation INSTALLATION PERSPECTIVES • Risk during Load-Out, Transportation and Installation • Reconsideration of Design Parameters • Safety during Installation • Size and Weight of the Structure Involved • Installation Methodology - innovative • Identify Marine Procedures • Reasonable risk from Owners/Underwriter’s points of view

  6. Installation – A Case Study INSTALLATION of MFP – A Case Study • Operator – Middle East • Feasibility Study for Installation with a Rig • Additional wells needed for accommodating increased oil flow => adjacent additional platform with Minimum Facilities proposed • Input from various contractors taken during feasibility study • Feasibility Study confirmed after thorough evaluation of feasibility of Installation • GLND developed Installation Procedures and Marine Procedures

  7. Installation – A Case Study INSTALLATION of MFP – A Case Study - Design considerations • Deciding parameters • Rig Capacity of Lift • Rig Reach of Lift • Safety of Existing Platform • Installation Methods • Risk Assessment and Mitigation

  8. Installation – A Case Study INSTALLATION of MFP – A Case Study - Steps • Position the Rig near to the existing platform • Cantilever extended, Install Pin pile • Template loaded, sea-fastened and arrives at the location • Template Lift with Rig, Lowered and Placed on the Bottom • Install Legs(Conductors)/ Work Platforms • Topside Lift after Rigging inspection • Final adjustment using tugger winches • Positioning Levelling and welding the Topside on the legs

  9. MFP – Installation Perspectives Step #1, #2 Position the Rig near to the existing platform, Cantilever extended, Install Pin pile Outreach -45’ Port/Sbd- 14.5’

  10. MFP – Installation Perspectives Step #3 Template loaded, sea-fastened and arrives at the location No welding to the deck (timber)

  11. MFP – Installation Perspectives Step #4 Template Lift with Rig, Lowered and Placed on the Bottom Mooring: Bow -1 Stern - 2

  12. MFP – Installation Perspectives Step #5 Install all other Legs/ Work Platforms Cutting at the desired elevation

  13. MFP – Installation Perspectives Step #6 Topside Lift after Rigging inspection Crash rail Air gap

  14. MFP – Installation Perspectives Step #7 Final adjustment using tuggerwinches Positioning is a delicate job

  15. MFP – Installation Perspectives Step #8 Positioning, Levelling and welding the Topside on the legs

  16. Installation – A Case Study INSTALLATION of MFP – A Case Study - Issues • Rig Limitations – DAF to be considered • Weather during Installation – very important • Positioning of the Rig – rig move and soil assessment • Placing of the Topside simultaneously on conductors/legs • Tugger Line and Lifting Gear – to be designed • Leveling of the Platform – suit to site

  17. Installation – A Case Study SUMMARY • Design Parameters - Reconsideration • Risk Assessment and Risk Mitigation • Installation Methodology – Innovation • Custom made procedures/design
