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

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


Installation a case study

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


Installation a case study1

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


Installation a case study2

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

Step #8

Positioning, Levelling and welding the Topside on the legs


Installation a case study3

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

SUMMARY

  • Design Parameters - Reconsideration

  • Risk Assessment and Risk Mitigation

  • Installation Methodology – Innovation

  • Custom made procedures/design
