The project

Al Salam Tunnel

Location: Abu Dhabi

Client: SAAED

Sector: Infrastructure

Period: July 2012 – October 2012

The brief

Al Salam Tunnel, later named Sheikh Zayed Tunnel, is the largest tunnel development in the Middle East, and was built to ease traffic conditions in central Abu Dhabi. The tunnel stretches from Delma Street, at the Sea Palace junction, up to the Corniche and Mina Road and includes four lanes in each direction. The covered section of the tunnel runs for 2.4 km, while the open section covers 1.8 km.

Olsson Fire & Risk was engaged to undertake a Tunnel Safety System Assurance Assessment in form of a full Quantitative Risk Analysis (QRA).

The solution

We conducted an initial analysis assessing risks due to fires, followed by the main tunnel safety system assurance assessment, including Preliminary Hazard Analysis (PHA), a detailed Layers of Protection Analysis (LOPA), Reliability/Availability/Maintainability (RAM) analysis as well as a review of the Safety Integrity Level (SIL).

Olsson Fire & Risk’s involvement in the billion dollar project meant that severe risks could be identified, addressed and mitigated to acceptable levels, ensuring an adequate level of risk to the people of Abu Dhabi.
