Oceanic Exploration Feasibility Study for the East Timor Pipeline

The continental shelf in the vicinity of Suai slopes to the southeast. The pipeline route presented in the A-0129.01-DWG-001 passes down the continental slope at a suitable angle, and is considered to be acceptable for the following reasons:

• The nearshore route by observation is acceptable for the following:
  • From Reference [3] the slope from land is relatively gentle.
  • Close to Suai is outlet for the Talara river. This usually assists in easing the construction of a landfall as the river deposits materials and hence eases pipeline construction.
• The route misses any existing facilities.

4.1.2 Continental Slope – Australia

The pipeline route presented in the A-0129.01-DWG-001 passes down the Australian continental slope at a suitable angle, and is considered to be acceptable for the following reasons:

• The slope from Bayu Undan to the maximum water depth is considered to be of an acceptable gradient from observation.
• The route misses any existing facilities.

4.1.3 Maximum Water Depth

From Reference [3] the maximum water depth is inferred to be approximately 2,500m for the selected route.

4.2 CONCLUSION

From the data available, the maximum water depth for the pipeline to East Timor is approximately 2,500m.

The route at this stage appears to be practical but more project-specific data is required to confirm this.
