AI Overview
Installing a 59 km, 18-inch offshore gas pipeline typically takes 8 to 14 months from start to finish. This timeframe heavily depends on the vessel used, seabed conditions, and weather.
Actual offshore pipe-laying usually progresses at a rate of 1 to 3 km per day, but the total project timeline includes several vital phases.
Phase-by-Phase Timeline
Engineering & Procurement (3–6 months): Ordering the steel, applying anti-corrosion coatings, and finalizing the route survey.
Logistics & Stating (1–2 months): Transporting the pipe joints to the coastal "spool base" or loading them directly onto the pipe-lay vessel.
Offshore Pipelaying (1–2 months): The physical welding, coating, and lowering of the 59 km of pipe to the seabed.
Trenching & Backfilling (1–2 months): Burying the pipeline into the seabed for protection against anchors and currents (if required by water depth).
Pre-Commissioning (1 month): Flooding, gauging, hydrotesting (pressure testing), and drying the pipeline before gas is introduced.
