Alkimos Outfall Pipeline

Description

Abyss Solutions was engaged by Water Corporation to undertake an in-service inspection of the interior of the Alkimos Ocean Outfall pipe. The objective of the work was to demonstrate Abyss Solutions’ ability to safely capture detailed imagery of the pipe interior during its operation on a small section of its length.

Inspection Overview

Abyss Solutions performed a visual inspection using a crawler type vehicle equipped with a set of 4 high-fidelity cameras positioned upwards to capture imagery of the pipe crown and downwards to capture imagery of the pipe wall and invert below water.

Methodology

The data collected was processed off-site and consisted of two stages:
1. Image Processing: All high-fidelity imagery captured was subjected to algorithmic enhancement to minimise any loss of colour information and detail for accurate fault identification.
2. Condition Assessment: Fault analysis was undertaken to identify defects such as cracked, delaminated, missing and spalled lining, etc.

Outcome

Abyss Solutions has successfully demonstrated its technology for the safe in-service inspection of the interior of ocean outfalls. Detail rich imagery was captured using a crawler type vehicle equipped with its high-fidelity imaging system. The data collected can be used to establish a visual baseline of the asset and assess its condition.
The inspection found that much of the inspected section of outfall pipe was in good to very good condition. However, several defects requiring monitoring, risk assessment and/or remediation were also identified.
