TBM Recovery from beneath the Arabian Gulf

The Herrenknecht AG tunnel boring machine AVN2000AB was safely recovered from the sea bed of Arabian Gulf last month. 14m long 110t 2200/2640 TBM located 10m under the seabed was excavated, transported almost 40km and offloaded using a 350t crawler crane onto a jetty, with sheer precision.

Thanks to a fantastic partnership between JV partners Al Hassanain and Joseph Gallagher Limited, the operation was completed in only 4 days despite adverse weather conditions with winds up to 50kmp/h and temperatures reaching 48 degrees Celsius).

A superb recovery completed by a dedicated multinational team. Utilising state of the art pipejacking and marine recovery led by JGL and JV partners Al Hassanain, combining the talents of both companies resulting in one fantastic delivery team. The final leg of the project will now involve the installation of a 350m long diffuser beneath the Arabian Gulf. Thanks to everyone who has played their part so very well
