  3. Pipeline? Platform Platform Pipeline 3 | Strength and Depth

  4. Pipeline? FPS Onshore Pipeline 4 | Strength and Depth

  5. Main Equipment 5 | Strength and Depth

  6. Conventional laybarge: • Using mooring to keep position • Coverage area up to WD 50-100m • Modern laybarge: • Using DP (dynamic positioning) to keep position • Coverage area more than WD 50m 6 | Strength and Depth

  7. Process Overview • Start-Up / Initiation • Loading and storage • Firing Line • Welding • NDT • Field joint coating • Tensioning • Laydown • Emergency • Abandonment and Recovery 7 | Strength and Depth

  8. Installation Analysis • Installation analysis: • Start up, normal laying, A/R analysis, laydown • Local buckling check • Fatigue analysis • Free span / bottom roughness • Based on DNV OS F101 • Section 12 K300, Simplified laying criteria • Area: Overbend and Segbend • Check: Stress and Strain • Result of analysis is exceed the criteria? • Environmental loads: Hs, T, current • Optimizations: roller setting (barge/stinger), tension, trim, stinger • Others: buoyancy tank 8 | Strength and Depth

  9. S-Lay Method 9 | Strength and Depth

  10. OFFPIPE Software • Static analysis: • Start up, A/R analysis, laydown, free span / bottom roughness • Dynamic analysis • Normal laying: RAO, environment condition 10 | Strength and Depth
