General description

Overview of Challenge

5

What is the nature of the challenge? (What is not adequately addressed at present?)

Pipeline route planning needs to accommodate ground subsidence / movement considerations.  Two phases: historical and ongoing.  Ongoing: Ground movement can damage pipelines / threaten integrity of infrastructure.

If  ground movement likely to cause damage can be identified early, then mitigation can potentially both reduce impact of damage and potentially reduce costs of repair.

6

Thematic information requirements

1. Obtain detailed topographic information,        9. Obtain detailed imagery of assets,     13. Monitor ground movement,

7

Nature of the challenge - What effect does this challenge have on operations?

Monitoring and applying suitable intervention measures.

8

What do you currently do to address this challenge?/ How is this challenge conventionally addressed?

Currently, pipelines are monitored by maintenance crews.  However, this is a slow process, and the amount of pipeline that can be covered in a set period of time can be limited.  A remote way of monitoring would be very useful and much more efficient.

9

What kind of solution do you envisage could address this challenge?

Ongoing data to highlight ground movement which could lead to failure events

10

What is your view on the capability of technology to meet this need? – are you currently using EO tech? If not, why not?

EO could be a useful complimentary technology
