Televiewer site investigation at Fujairah for Stage Two of the Etihad Rail Project

Stage Two of the Etihad Rail Project www.etihadrail.ae extends 605 kilometres from Ghuweifat on the border with Saudi Arabia to Fujairah on the UAE’s East Coast, to be followed by future route additions.

The volume of goods transported on the full Etihad Rail network will increase from the current seven million tonnes per year on Stage One, to more than fifty million tonnes annually.

The network will connect the Emirates via Abu Dhabi, KIZAD, Khalifa Port, Jebel Ali Port, Dubai, Sharjah, Ras al-Khaimah, and Fujairah on the East Coast, linking with the existing line at Ruwais, effectively uniting the major industrial ports and trading centres of the country.

Robertson Geo client – The Arab Centre for Engineering Studies (ACES) www.aces-int.com – commissioned the subsurface investigation of the site located within the emirate of Fujairah. Optical and Acoustic televiewer logging was used to evaluate the geophysical properties of rocks to confirm the information on joints for the slope design of the proposed sites. The High Resolution Optical Televiewer (Hi-OPTV) generates a continuous orientated 360-degree image of the borehole wall using optical imaging to give detailed structural data of fracture detection and evaluation, location, strike, and dip of joints. The High Resolution Acoustic Televiewer (HRAT) provided a continuous orientated 360-degree image using ultrasound transmitting pulses to give detailed orientated structural information.

22 logging tests were successfully completed on the site.
