Mammoet transports two onshore oil rigs from the UAE to Oman

Company manages entire logistics chain for transport of units weighing up to 471t each from factory to the final destination under contract from Oman’s Khimji Ramdas Shipping

Mammoet has transported two pre-assembled onshore oil rigs and accessories, each weighing up to 471t, by sea and land from the UAE to Oman under a contract by the sultanate’s Khimji Ramdas Shipping (KRS).

The global heavy lifting and transport specialist said it had been contracted by KRS to safely deliver the rigs from its fabrication facility in Dubai’s Jebel Ali to the site in Nimr, Oman. Manufactured in the UAE, the new-generation, fast-moving rigs are a new addition to the current fleet of Oman’s largest drilling company – Abraj Energy Services SAOC.

“Shipping of oversized and heavy cargo requires specific expertise, as infrastructure limitations create bottlenecks that demand alternative transport approaches. At 37.7m long and 10.7m high and up to 471t, the sheer size and weight of the pieces meant Mammoet had to compose an optimal route for the cargo by performing the necessary route studies and obtaining required permits,” said a statement from Mammoet.

Advanced preparations were needed, added the company, including road infrastructure modifications to temporarily replace over 100 streetlight poles and traffic signals, plus construction of temporary bridges protecting underground electrical cables and pipelines, to ensure transport safety and infrastructure integrity. The route also crossed the UAE’s most frequently used highway – E11 – connecting Abu Dhabi with Dubai.

Each rig comprised three major parts and three smaller parts, weighing 147–471t, and the largest rig component measured up to 37.7m long by 13.5m wide by 10.6m high. They were jacked up onto beams and stools at the fabrication facility in the Jebel Ali Free Zone, then transported to the Port of Jebel Ali using conventional trailers and trucks. The cargo was then loaded-out at the port onto a Mammoet 300-class barge for onward shipment to Oman, where it was received and loaded-in at the Port of Duqm. From there, the rig sections were transported over a distance of 400km to the site in Nimr.

Muthu Esakki, project manager, Khimji Ramdas Shipping, said: “The prompt logistics for the movement of the packages based on the client’s timeline was critical to the overall success of the project. KRS and Mammoet team worked closely and managed the end-to-end logistics from the UAE to Oman. The challenge was to overcome hurdles arising due to the sheer size of the packages and moving them between two countries using sea and road modes. This involved extensive coordination and support from the government authorities in both countries and we are thankful to all stakeholders for their support.”

Ali Kobeissi, project manager, Mammoet, added: “Teamwork and cohesive collaboration with government authorities and police, in both the UAE and Oman, were the key to mitigate risks and have all permits in place. Thorough planning and coordination ensured we were able to meet the needs of our customer by safely delivering the rigs to their final location.”
