Gas pipeline construction - Import export

The QuellTech laser sensor family Q4 or Q5 used for these tasks is generally mounted on an arm of a rotational axis, to scan along the complete 360° angle of the internal surface in a sequence of strips. The Q4 sensors can also be used to control the weld seam tracking itself for rapid setup and ease of use. Even during a project, the range and scope of the Q Series sensor demonstrates the advantages of a modular system to quickly adapt to project needs, where the smallest system has provided fast analysis of pipes as small as 105mm. The low power, with standard communication protocols, enable battery powered systems to transmit wireless data to other systems for review and cloud back up.

During the Nord Stream 2 project several Aerolift lifting solutions were used on multiple locations. It is world’s largest pipeline project. During the project, a pipeline is laid through the Baltic Sea, which will transport natural gas over 1,200 km. From the world’s largest gas reserves in Russia via the most efficient route to consumers in Europe. Over 200.000 pipe segments needed to be handled. Almost all handling movements are carried out by an Aerolift lifting solution!

The Aerolift pipe lifting solutions are applied for many different situations and places. During production, storage, transhipment, and internal transport. For this specific situation we designed a lifting solution to handle bare and coated pipes aboard the ship. The ship, The Amazon, was converted to an ultra-deepwater J-Lay vessel. Our vacuum lifting devices are installed on 4 cargo hold cranes. In tandem mode the cranes will be used to load and unload 24-meter-long pipes in a cargo. The lifting devices are designed to limit deflection of double joint pipes or to handle the entire pipe by vacuum only.
