Transcript of "Modularization the-key-to-success"

  1. 1. Modularization; The key to succesDockwise – 24 August 2011
  2. 2. Agenda■ Introduction to Dockwise■ Why Modularization■ Designing Module Transports■ Advantages of Self Propelled Vessels■ Dockwise Logistical Management■ Conclusion and Closing Remarks
  3. 3. Dockwise Group of Companies
  4. 4. Dockwise Engineering Services Floating Structures Fixed Structures Platform Float-Over Module Design Design verification
  5. 5. Offshore Installation EquipmentDesign, fabrication and testing of float-over installation systems
  6. 6. Dockwise Yacht Transport
  7. 7. New super vessel; Dockwise Vanguard
  8. 8. Technical details of the new vessel A■ Overall length: 275 m■ Deck width: 70 m■ Hull Depth: 15.5 m■ Water above the deck: 16 m■ Draft: 11 m■ Max. carrying capacity: 117.000 metric tons (DWT)■ Power: 27 MW (diesel electric)■ Propulsion configuration: 2 Main propellers (controllable pitch in HR Nozzle) 2 Retractable Azimuth thrusters■ Speed : 14 knots
  9. 9. Target market A■ Floating production structures: TLP (integrated with topside) Semi’s (integrated with topside) Spar hulls■ Gravity based production structures■ Semi-submersible rigs■ FPSO’s■ FLNG■ Semi-submersible crane vessels■ Vessel dry docking
  10. 10. Why Modularization ? Reducing Risk and Interfaces , while optimizing cost (control )Global Sourcing; More quality More competitionBetter controlled fabricationresults in tighter tolerancesImproved site infrastructure
  11. 11. Optimizing Transport design■ Stowage forms■ Vessel strength■ Load out issues■ Stability■ Motions■ Ballast capacity
  12. 12. Example modular transports -piggyback■ Quick load / discharge of barges■ HTV not tied up for lengthy operations■ Barges can go into shallow ports and rivers
  13. 13. Example modular transports – direct stowage on deck■ Modules trailered or skidded on/off■ Quayheight / waterdepth are critical during loadout
  14. 14. Loadout analysis - skid on Critical parameters: ■ Waterdepth at quay ■ Quay height above water ■ Load spreading in HTV
  15. 15. Load out analysis - roll on Critical parameters: ■ Waterdepth at quay ■ Quay height above water ■ Load spreading in HTV
  16. 16. Waterdepth and quay height
  17. 17. Quay height and tide■ If the quay is to high the vessel can not keep the deck in line with the quay.■ The vessel must ballast fast enough to keep up with the tide.
  18. 18. Seafastening / Structural analysis■ Accelerations during transit are important design factor■ HTV motions much better than tug / barge■ Designing for the right transport vessel can safe a lot of steel in the module
  19. 19. Advantages of Heavy Transport Vessels■ Carrying capacity■ Sailing speed – reduced transit time■ Cargo Safety■ Better motion behavior → smaller accelerations / steel
  20. 20. Safety at sea OCTOPUS Onboard - SPOS with Motion Monitoring■ Voyage Calculations Design Sea-state Loads on Cargo■ Safety limits/margins Statistical data Probability of Exceedence■ What will be encountered in reality?■ How will your vessels respond to waves?
  21. 21. Method – System description■ System description sensor box: sensor:
  22. 22. Purpose and Principles (1)■ Decision Support - provide Master with: expected motion response real-time measurement of accelerations■ Motion Monitoring provide client with actual motion data provide Engineering with data for: validation of engineering tools validation of long term statistics
  23. 23. Purpose and Principles (2)■ Safety increase more decision information for Master more insight in engineering calculation accuracy■ Design improvements reduced design wave? generally accelerations are 50% or more below design values■ Operational costs reduce weather delays
  24. 24. Dockwise Logistical Management Door-2-Door Solutions1. Load-out fabrication yard 2. Heavy Marine Transport 3. Load Off and Land Transport 4. Installation and Site-Assembly
  25. 25. Dockwise Logistical ManagementBenefits Traditional Project Dockwise Logistical Logistics Management Multiple charter parties Single logistical management partner Time chartered vessels Dedicated project vessels including management and engineering Separate onshore/offshore heavy Complete lumpsum D2D haul service agreements transportation solutions Full schedule risk with Owner Manages schedule risk
  26. 26. Why Dockwise ? Reducing Risk and Interfaces , while optimizing cost (control ) Risk Interfaces Cost (control)Decades of track record Manages interfaces with Lumpsum full scope onshore transportation contractingMost experienced PM & Manages third party Economy of scaleEngineering vesselsSelf propelled vessels Accepts full schedule riskAccepts full schedule risk 29
  27. 27. Conclusions and Recommendations■ Early Concept Selection and Transporter Involvement■ Designing Logistics into the Project■ Think BIG Reduce interfaces What limits the size of the modules you can get to site?■ Transport is critical part of the design !!!! Dimensions – which vessels are available ? Check load out facility – can we get in ? Piggyback or direct stowage on deck ? Float on, skid on or roll on ?
  28. 28. Conclusion:Always plan ahead carefully…..!!!
