For placing pipelines and service routes microtunnelling is increasingly popular in the Middle East, but this is not without complexity and risk. Ground conditions can be particularly challenging, with abrasive soils, higher ambient temperatures and high ground water tables on costal projects all posing potential risks.
The key to successful microtunnelling projects is the correct selection of machine, as borehole surveys and old plans may not give a true picture of what is likely to be encountered. The ISEKI range of machines are made to suit all ground types as was evident on our recent project in North Sitra, Bahrain.
Early into the tunnel drive the ISEKI TCS 600 Rock Machine encountered a mixed face of rock and sand with cobbles and boulders on the tunnel horizon. Although this slowed production slightly, the combination of our experienced operators and the capabilities of our chosen microtunnelling machine dealt extremely well with ground conditions, completing the installation successfully.
Our ISEKI range of microtunnelling equipment sets the standard in terms of versatility and reliability in the Middle East. We own and operate over 30 microtunnelling systems with internal diameters ranging from 250mm to 2800mm and ten of these machines are currently based between Bahrain, Kuwait and Abu Dhabi, meaning we can mobilise machines quickly across the region.
