Abstract
The Middle East to India Pipeline (MEIDP) will provide an economic and secure source of gas for India, where the demand for energy will continue to increase over the coming decades. The proposed pipeline will be the deepest major infrastructure pipeline laid with water depths exceeding 3000m for significant sections of the 1200km route. In addition to its depth the MEIDP will have to contend with significant potential geohazards, namely the Indian and Omani continental slopes, the Indus Fan channels and the Owen Fracture Zone.
At the Owen Fracture Zone (OFZ) the MEIDP crosses the continental plate boundary between the Arabian and Indian tectonic plates, which meet forming a right lateral strike slip fault movement zone. The movement on the plate boundary will be investigated and examples of survey data will demonstrate the challenges that need to be overcome in crossing this major geohazard feature. At the Indus fan the MEIDP route crosses deep channel/levee system that are characterized by central channels with a series of adjacent terraces and numerous abandoned channel loops, which are partially refilled by the overspill sediments from active canyon areas. The pipeline route crosses five turbidity current channels with side walls up to 200m high, in water depths between 2100m - 3200m, with channel side slopes up to 25.
This paper reviews the findings of the 2013 geophysical reconnaissance survey in these two areas and summarises the geohazard design process required and work performed on the project to identify a feasible route across the Owen Fracture Zone (OFZ) and the crossing of the Indus Fan Channels. It also gives general guidelines for suitable design solutions for dealing with fault crossings; debris & turbidity current flow, slope stability and run-out.
