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 tugger winches
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
